In particular, the Center will uniformly manage, centrally connect and distribute electronic health declaration data, domestic movement declaration data, people’s reflection data, quarantine point data and data on control of entry and exit of quarantine points between Covid-19 epidemic prevention and control technology systems… Step 1: Visit https://www.bluezone.gov.vn or download directly at App Store or CH Play. Step 2: Once downloaded, the application will ask for permission to use Bluetooth to record contact with other Bluezone installed users. If Bluetooth is not open, drag the status bar and turn on Bluetooth; or go to Settings, select Bluetooth and turn it on. Step 3: Once the installation is done, click Scan Around. If someone near you less than 2m has used Bluezone, the application will automatically identify these users and put them in the contact list.

“Last March, I flew to Hanoi for work. Before that, I made a medical declaration on the web, but forgot to take a photo. I thought the data would be on the Bluezone app because this app also has a declaration section. , when I went to the airport to open the app, I knew I had to make a medical declaration from the beginning, which took time,” shared Ngoc Mai, an office worker living in Ho Chi Minh City. “On the last election day, I still had to make a medical declaration when I went to the place. I don’t understand why they didn’t let me scan the QR code that I just declared a few days ago,” said Ngoc Phuong, living in Ba Dinh district, Hanoi. said. Minister of Information and Communications Nguyen Manh Hung said that anti-epidemic applications currently use a unified data store. Photo: VGP. Share with Zing , a representative of the Department of Informatization, under the Ministry of Information and Communications affirmed that the database of applications is now interconnected, helping to increase the efficiency of the applications and reduce the cumbersome for people. Why does the application need data communication? Mr. Do Lap Hien, Deputy Director of the Center for E-Government, under the Department of Informatization, explained the inconvenience when applications use independent and unconnected data. “In the past, there were cases where people declared their health on the NCOVI app, then downloaded more Bluezone to protect themselves. When going to a quarantine point, opening the health declaration function on Bluezone, there is no previously declared data. This is really inconvenient. In the opposite direction, the trace group when accessing the information of the Bluezone app, the data in the app is just the phone’s code. They have to find the corresponding information in the NCOVI or VHD database to know who and where the close contact is. This process will reduce the tracking speed,” said Mr. Hien. Anti-epidemic applications all have medical declaration functions. Data warehouse interoperability ensures this functionality works across applications. Photo: Tuan Anh. During the National Online Conference on the situation and urgent solutions to prevent and control the Covid-19 epidemic on the morning of May 29, Minister of Information and Communications Nguyen Manh Hung said that the current anti-epidemic applications have used a unified data warehouse. . “Once synchronized, only one operation can access all information on the applications, more effective in fighting the epidemic,” Mr. Hien shared. Centrally connected IT applications, linked data. This is an important development step in the application of technology and data. Minister of Information and Communications Nguyen Manh Hung According to the representative of the Center, when updating to the latest version, the applications will use the linked data. This is to ensure that the people’s experience is seamless and unaffected. The latest version of Bluezone will be updated on the iOS and Android app stores this week. “For citizens and users, all changes must be ‘transparent’ to them. The application must not change anything about the user experience, only more convenient, “said Mr. Hien. App data will delete itself after a month Despite being propagated about anti-epidemic applications, many users said they encountered difficulties and inconveniences when using. For example, with the Bluezone application, having to constantly turn on the Bluetooth connection makes users worry about consuming the smartphone’s battery. “I installed Bluezone since last year, but sometimes it bothers me because there are too many notifications. Also, I don’t know if the app is effective because now I don’t see the number of people exposed to almost the same amount of time,” Anh Hoang said. , working in Hanoi shared. In addition, the information that people who do not install Bluezone may be fined is also confusing. Reply Zing , a representative of the Information Technology Department, Ministry of Health said that the fine or not will depend on local regulations. Bluezone application supports the process of tracing, close contact. Photo: VH. “The regulation clearly states that when going to a public place, it is mandatory to install the Bluezone application and turn on Bluetooth. If it is in a personal space, at home or in a place where there are not many people, it is not necessary. The sanction will depend on the risk or development of the epidemic in the locality. Thus, depending on the local situation, the sanction will be assigned to the People’s Committees of the provinces and cities for their own consideration and decision”, said Mr. Nguyen Truong Nam, Deputy Director of the Information Technology Department, Ministry of Industry and Trade. Health said. Personal data will be deleted after one month of storage so that people can rest assured to comply. Minister of Information and Communications Nguyen Manh Hung In addition, there are also concerns about the security of people’s personal information. Sharing about this issue, a representative of the Center for E-Government said that current data according to regulations will be deleted after 30 days. This number may change depending on the development of the disease and the requirements of the Ministry of Health. “Currently reserved data will be deleted after one month. When deleted, it will be completely deleted and cannot be retrieved, in order to ensure the privacy of users, “said Mr. Hien. Due to anti-epidemic requirements, many units and objects can access anti-epidemic data. However, depending on the scope and needs, these objects will have limited access. Not everyone can access the user’s data and information. In addition, according to the Minister of Information and Communications, wearable isolation monitoring devices will be deployed from June 1, immediately for workers in industrial parks. This bracelet is part of a seamless system, data will also be shared with other applications to ensure isolation. “Currently, the new bracelet solution is being tested at the request of the Ministry of Health. Regardless of the technology application, we will ensure that the data is attached to the application, which is part of the system.” representative of the Center for E-Government said.

The website of the Ministry of Public Security has just said that on June 1, Minister To Lam had a letter of commendation and recognition of the results and achievements that the members of the Steering Committee for building the project “Database of National population data” and the project “Production, issuance and management of citizen identification”, the Ministry of Public Security and local police have achieved in recent times. According to Minister To Lam, the campaign to implement the two projects has achieved important results. Despite difficult conditions due to the impact of the Covid-19 pandemic, by June 1, the national police force had reached the milestone of receiving 50 million dossiers for issuance of citizen identity cards with electronic chips. Complete the target 1 month ahead of schedule. According to the original plan, the Ministry of Public Security aims to issue about 50 million citizen identification cards with electronic chips by July 1. (Photo: haiphong.gov.vn) Along with that, the police force nationwide has cleaned 80% of the national population data on the system, creating a solid basis for granting identification numbers to 100% of citizens nationwide and ready to connect with the Internet. ministries, branches and localities, contributing to promoting the building of e-Government and national digital transformation. In his letter of commendation, Minister To Lam also emphasized that the time from now until the completion of both projects on July 1 is not much, the tasks posed are very heavy, difficult and urgent. Therefore, the head of the Ministry of Public Security requested the Ministry’s Steering Committee and the Directors of the Public Security of the provinces and cities to continue directing and promoting the synchronous and comprehensive implementation of the contents of the project “national database” on population” and the project “Production, issuance and management of citizen identification”, striving to complete on schedule, contributing to building e-Government, administrative reform and serving economic development – society of the country. Previously, answering people’s questions about whether the citizen ID card with an electronic chip can replace documents in administrative transactions, the Ministry of Public Security said, the citizen ID card with an electronic chip with high security, large storage capacity, allowing the integration of many accompanying applications such as: digital signature application, biometric application, one-time password application … can be used and connected widely for public and private services. In the coming time, when the citizen ID card with an electronic chip has fully integrated information, people will not have to carry many types of documents when they go to transactions and do the procedures, just use a valid citizen ID card. Inserting electronic chip will perform transactions. In addition, the chip integration on the Citizen ID provides flexibility when it is necessary to add or modify information on the card after it is issued by the police. Data on the chip can be accessed immediately without being dependent on the network connection through devices that allow reading information on the chip, making identity authentication done immediately, minimizing multiple identity spoofing. Currently, the Department of Informatization, the Ministry of Information and Communications and the Police Department for Administrative Management of Social Order (C06) and the Ministry of Public Security are urgently coordinating with localities to connect information systems to serve the public. providing more than 200 level 4 online public services with the National Population Database, through the National Data Sharing Integrated Platform – NGSP. Once completed, people when using more than 200 online public services of this level 4 will be reduced to require personal papers.

Always wear a mask, open the Bluezone app, declare health when going to public places. Accordingly, for technologies that are promoting effective epidemic prevention and control, it is necessary to change and switch from voluntary encouragement to compulsory installation of some basic applications. THREE “Attack” against COVID-19 Currently, there are three “attacks” to prevent the Covid-19 epidemic: Increasing testing on a large scale, implementing a vaccine strategy and applying technology for tracing. In particular, the use of technology chaired by the Ministry of Information and Communications is promoting effectively. Deputy Minister of Information and Communications Nguyen Huy Dung said that the new approach from the Prime Minister’s point of view is a harmonious combination between prevention and attack. Previously, medical declaration applications for epidemic prevention and control, and support for tracing only recommended people to use, but now will become mandatory. Second, anti-epidemic data sources must be centralized in one processing hub. Previously, because people declared through different applications, the data was scattered. Now the data must be centralized so that advanced and modern technology can be applied to perform the analysis to produce the required results. Mr. Nguyen Truong Nam, Deputy Director of the Information Technology Department (Ministry of Health), said that for the health declaration for the entire population, people can declare through 3 applications: NCOVI, Bluezone and Vietnam Health Declaration. Specifically, Vietnam Health Declaration is a software of the Military Telecommunications Industry Corporation (Viettel), so the declared data is stored at Viettel. Data declared by people on Bluezone (of Bkav Technology Group) and NCOVI (of Vietnam Posts and Telecommunications Group – VNPT) are stored centrally at the Department of Informatization (Ministry of Information and Communications). After being collected, the medical declaration data will be collected by the Centers for Disease Control and Prevention (CDC) in provinces, agencies and units according to their competence. This data is used for control, analysis and case tracing. Meanwhile, many units still use paper declaration and electronic declaration in parallel. Faced with the fact that medical declaration data is still scattered, the Information Technology Department (Ministry of Health) is working with units to promote data interoperability and build a centralized medical declaration database. central, connected. INSTALLATION AND USE OF THE APP WILL BE REQUIRED According to experience from previous infections, the next epidemic is more difficult, complicated, unpredictable than the previous one, the consequences are more severe, the treatment is more difficult, and the impact is worse. At the Government Standing Meeting on Covid-19 epidemic prevention a few days ago, the Prime Minister noted: currently the number of new infections and deaths on the world epidemic map continues to increase; illegal entry and residence tend to be more in recent times; appeared subjective, negligent and unwary thoughts of many localities, agencies, units and people; centralized isolation management, after isolation (when returning to the locality) is still inadequate; The new strain of the SARS-Cov-2 virus spreads quickly, is difficult to detect, and has complicated developments. It is predicted that the epidemic situation will continue to be complicated, it will be long, it is not possible to confirm the time when the epidemic will end. Therefore, we must be ready to deal with the epidemic at the highest level, and we must live safely while the epidemic is still around us. Following the direction of the Prime Minister, the Ministry of Information and Communications has issued the document “Guide to use the set of solutions to support Covid-19 prevention, control and tracing in the community”. This set of solutions includes Bluezone (a close contact warning application for suspected Covid-19 patients), NCOVI (voluntary health declaration management system), medical declaration for people on entry, and a system to record people coming and going to public places (via QR code scanning) and Covid-19 safe anti-epidemic map system. Currently, there are 9 provinces and cities nationwide that have implemented Covid-19 epidemiological information mapping software (called CovidMaps). The CovidMaps map allows real-time monitoring of the epidemic situation in Da Nang, Bac Giang, Vinh Phuc, Bac Ninh, Quang Ninh, Quang Nam, Gia Lai, Phu Yen and Lang Son. The Covid-19 epidemiological information map (CovidMaps) helps the community to visually monitor epidemiological information of local cases via the Internet, the government has more digital technology solutions to serve management and control. practice in epidemic prevention and control. According to the information in the document “Guidelines for using a set of solutions to support Covid-19 prevention, control and tracing in the community,” if 60% of adults install the Bluezone application on their phones, the reported data about cases of close contact, contact with people with Covid-19 will reach an almost absolute level of accuracy. Therefore, in order to promote effectiveness in epidemic prevention and control, it is necessary to join hands to use and voluntarily declare accurately information of the people and the community. Many people think that installing and using the application will become a mandatory requirement, like wearing a mask. For industrial parks and factories, the Ministry of Information and Communications has proposed that people working in industrial parks, factories and enterprises must install the Bluezone application and the NCOVI medical declaration application. .
At public places, offices need to scan QR Codes to be able to collect digital data on the system to record arrivals or departures at public places. In addition, any citizen when going to crowded places needs to install the Bluezone application, to be able to detect close contact with infected people (data already stored on the system). The Government Office issued Official Letter No. 3440/VPCP-KGVX to the Ministry of Health and the Ministry of Information and Communications with the content considering the proposal of the Ministry of Information and Communications on the implementation of a number of information technology applications and Connecting surveillance cameras to support the prevention and control of the Covid-19 epidemic. Persons subject to medical supervision and isolation must declare mandatory information on the application. This mandatory also requires the awareness of the community not only to install the application on the mobile device, but to enable the connection for the application to work. Moreover, using Bluezone and turning on Bluetooth when going to public places, when exposed to large numbers of people, will help people protect themselves and the community, and at the same time help in zoning out the epidemic and tracing it quickly. . When a Covid-19 patient is detected, only those at high risk are quarantined instead of isolating everyone involved. The Ministry of Information and Communications has just sent an official dispatch to the People’s Committees of the provinces and centrally-run cities and the Departments of Information and Communications of the provinces and cities about the implementation of the surveillance camera system at the agencies. centralized isolation facility to prevent Covid-19.

Accordingly, in the face of increasingly complicated developments of the Covid-19 epidemic in the city, the Department of Informatization recommends agencies and units under the Ministry of Information and Communications to use technological solutions for medical declaration. Manage people entering and exiting the office. Specifically, in addition to officials, civil servants, public employees, and employees in the agency, all guests coming to contact work are required to install and turn on the application to install the Bluezone proximity detection application before go to work. This rule only excludes those who do not use smartphones. Bluezone application is the most effective tool to trace people suspected of being infected with Covid-19. Photo: Trong Dat At the entrance of offices and units under the Ministry of Information and Communications, the Department of Informatization recommends that you paste a QR Code to install the Bluezone application at a recognizable location to support users. Guests who come to work at agencies and headquarters of the Ministry of Information and Communications also need to make an electronic medical declaration. The declaration will be made on 1 of 3 applications Bluezone, NCOVI, Vietnam Health Declaration or on website tokhaiyte.vn. The paper medical declaration will only be applied to those who do not have a smartphone. In addition, agencies and units in the Ministry of Information and Communications have also been advised to manage people entering and leaving the office by scanning QR codes. To do this, units need to register for a “quarantine point” and get their QR code at website tokhaiyte.vn. This QR code will be printed and pasted at a recognizable location at the entrance of each agency or unit. Scanning QR codes is a measure to save users’ epidemiological milestones. Guests coming to contact business will be forced to scan a QR code for quarantine using one of the 3 applications Bluezone, NCOVI, Vietnam Health Declaration. In the event that after scanning the quarantine QR code, the application says that the user has not made a medical declaration or the declaration has expired, they will be forced to make a medical declaration and re-scan the code. At the entrance to the offices, the Department of Informatization also recommends arranging a department to check and monitor the scanning of quarantine QR codes of employees and visitors to contact for work. Using the Bluezone tracing app, electronic medical declarations and scanning QR codes for quarantine are just 3 of the 5 anti-epidemic solutions with technology proposed by the Ministry of Information and Communications to localities. Previously, sharing at the current news at 19:00 on May 26 of Vietnam Television, Deputy Minister of Information and Communications Nguyen Huy Dung said that renewing the approach to technology in Covid-19 prevention and control is a combination balance between “defence” and “attack”. In terms of technology, “attack” is the mandatory use of some key applications to prevent Covid-19, instead of just recommending as before. If before, data was distributed by application, now data must be managed centrally. Deputy Minister of Information and Communications Nguyen Huy Dung. The Ministry of Information and Communications has proposed mandatory use of Bluezone application. Workers in industrial parks, factories and enterprises are required to make medical declarations. People using smartphones are required to use an application to identify close contact when going to a public place, where there are many people. Public places and offices must control people coming, going, leaving and entering by scanning QR codes. The fourth measure is to use technology to support the monitoring of people in medical isolation. According to Deputy Minister Nguyen Huy Dung, turning on Bluetooth and using the Bluezone application when going to public places will help users protect themselves, protect the community, assist in zoning out the epidemic, and quickly trace. When that happens, it will also help isolate high-risk people, rather than everyone. For agencies and organizations, effective disease prevention will help agencies, organizations, factories and enterprises maintain normal production and business activities. Trong Dat

Hanoi is the locality with the most people downloading the anti-epidemic application Bluezone Out of 33 million people using Bluezone, more than 20.58 million people have entered their phone number in the information on the application. The number of people providing phone numbers to the authorities has increased by nearly 1 million people compared to April 28, 2021. The two localities leading the country in the number of people downloading the Bluezone application are Hanoi (3.1 million people) and Ho Chi Minh City (2.83 million people). In the opposite direction, provinces like Dien Bien (70,500 people), Tuyen Quang (121,000 people), Yen Bai (130,000 people), … are the localities with the lowest number of people downloading Bluezone. Considering the percentage of population, Da Nang (43.7%), Hai Duong (40%), Hanoi (38.6%), Quang Ninh (37%), Bac Ninh (34%) are localities has the most number of Bluezoners. However, there is a fact that the number of people who download and actually use the Bluezone application is still a significant difference. In Hanoi, where the most people download Bluezone, the number of Bluezone accounts actually active is only 1.23 million, accounting for 40% of the total number of accounts. Meanwhile, in Ho Chi Minh City, the number of real Bluezone users (turn on Bluetooth for Bluezone to work) is about 1.1 million people, accounting for 38% of the total number of accounts. The same thing happened in Da Nang (40%), Hai Duong (38%), Quang Ninh (38%), Bac Ninh (39%), Hai Phong (38%), Thai Nguyen (38%) when not Which province or city has the number of people actually using Bluezone exceeding 50% of the population. Currently, Hanoi, Bac Ninh, Bac Giang, Vinh Phuc, Da Nang,… all have documents to encourage people to apply technological solutions such as electronic medical declaration and install Bluezone application to prevent , anti-epidemic. The Bluezone application is currently one of the five recommended technology solutions to prevent the spread of Covid-19. This is a low energy Bluetooth technology application solution. Smartphones with Bluezone installed can communicate with each other, recording close contact. The exposure history data will only be saved on the user’s mobile device. When there is a new infection and that person’s mobile phone has Bluezone installed, the contact history will be used to alert those who also have Bluezone installed and have been in close contact with the case. Bluezone can also help alert F2 people (close contact with F1). Bluezone warns if the user has been in close contact with someone infected with Covid-19, helping to reduce the risk of spreading in the community, helping people return to normal life.

The number of people downloading and using Bluezone has increased sharply recently, since the new wave of the Covid-19 epidemic broke out in Vietnam. According to information from the Department of Informatization, as of 5pm on May 11, the Bluezone application has surpassed 31.88 million downloads. The number of downloads of Bluezone applications has increased by 131,000 times compared to May 10 and 1.3 million times compared to April 28 – the beginning of the wave. Covid-19 The current. Many people have downloaded and used the Bluezone application when they heard about new developments about the situation of the Covid-19 epidemic in Vietnam. The Department of Informatization also said that out of a total of nearly 32 million downloads of Bluezone application, the total number of phone number subscribers has surpassed 20 million. These are encouraging results for epidemic prevention and control in Vietnam, especially when Bluezone is currently one of the five recommended technology solutions to combat the spread of Covid-19. Currently, Da Nang, Hai Duong, Hanoi, Quang Ninh, and Ho Chi Minh City are the 5 leading localities in the country in terms of the percentage of Bluezone users in terms of the total population. Accordingly, there were 491,000 Bluezone users in Da Nang (accounting for 43.28%). This number in Hai Duong is 676,000 people (accounting for 39.65%) and in Hanoi is more than 3 million people (37.74%). The number of Bluezone users in the remaining provinces in the top 5 are Quang Ninh 470,600 people (accounting for 35.64%) and Ho Chi Minh City 2.8 million people (accounting for 31%). In the opposite direction, the provinces of Thanh Hoa, Nam Dinh, Dak Lak, Nghe An and Dien Bien are ranked at the bottom with a low percentage of Bluezone users, accounting for less than 14% of the total population. Bluezone is currently the most effective technology solution to prevent and combat Covid-19. Bluezone is an application that records contact history, thereby providing early warning and helping to accurately trace people suspected of being infected with Covid-19. The effectiveness of Bluezone has been proven when this application helps health authorities trace thousands of suspected cases of close contact with infected people or new suspected infected people. Notably, 17 positive cases were found thanks to Bluezone during the second outbreak in Hai Duong in January 2021. These are all cases found outside of the trace list by normal epidemiological investigation. The advantage of Bluezone is to help detect early cases of close contact with people infected with (suspected) Covid-19 but do not know or have no symptoms of the disease. Bluezone users will therefore be warned early in case they have ever been in contact with a potential carrier. The use of Bluezone in combination with epidemiological investigation methods will help minimize the number of people who have to be isolated. Instead of thousands of people having to go to quarantine for prevention as before, the number of quarantined people will now be reduced to a minimum. According to experts’ estimates, for Bluezone to be effective, the percentage of users of this application must reach at least 60% of the adult population. In Vietnam, 50 million people install and use Bluezone is enough to effectively protect the whole community. Currently, the number of Bluezone users in Vietnam is still low. Therefore, for the application to be effective, it is necessary to have the cooperation of the whole community through downloading and using Bluezone.
