The government promotes safe travel with red and yellow codes to protect overseas Chinese: electronic needle card network comparison data

The government officially announced the reduction of the quarantine period for stores and the introduction of red and yellow codes. Regarding the technologies involved, Fang Baoqiao, Honorary President of the Hong Kong Information Technology Chamber of Commerce, pointed out that the key lies in the electronic needle card, the updated version of safe travel, and the verification QR code used in the premises. All scanners need to be connected to the Internet, and the user's electronic pin card contains personal data, which will be encrypted and uploaded to the "Government Cloud" for comparison. The scanner will sound a siren.

Every time you open the Anxin Travel Electronic Card, the data will be uploaded to the "Government Cloud"

Fang Baoqiao, Honorary President of the Hong Kong Information Technology Chamber of Commerce, pointed out that according to his understanding, under the new system, after users update the Safe Travel app, every time they open the app, the electronic pin card loaded in the app will be encrypted, resulting in a bunch of unique , and then compare it with the data in the "Government Cloud".

The "Government Cloud" has a list of confirmed cases and quarantined persons. By comparing it with the encrypted "serial number" uploaded by the user, if the user is found in the list, their safe travel will be displayed as a red code or a yellow code.

Fang Baoqiao also mentioned that in addition to uploading the data every time it is opened, it will be compared with the data in the "Government Cloud". After the electronic pin card, the data is also encrypted and uploaded to the "Government Cloud" for data comparison. This approach is "the second layer of protection".

If you travel with peace of mind, it is also valid to scan the paper needle card at the place where there is no electronic needle card.

He continued to point out that even if the user does not put the electronic pin card into the safe travel, or the mobile phone has no Internet access, or even uses a paper pin card, under this mechanism, the premises can be uploaded through the "verified QR code scanner" And compare the data to confirm whether the people entering the venue are diagnosed or quarantined.

Worried about system overload, but authorities say they have tested

Fang Baoqiao continued to raise a few concerns, including that every time the updated version of Anxin Travel is opened, the data will be encrypted and uploaded and compared. Whether the system can cope is another concern.

However, he revealed that the government department had said that it had done tests and believed it was sufficient to cope with the huge usage.

Mobile Internet speed may become a bottleneck

He also said that the updated version of Safe Travel requires the Internet to travel. Citizens’ mobile phones have different Internet speeds, and whether it will affect their travel will be observed after implementation.

At the same time, the verification QR code scanner used in the premises, but the mobile phone currently used as the scanner may not have Internet access function, the person in charge of the premises may need to add a calling card or use Wi-Fi.

He did not mention that some public Wi-Fi speeds are slow and the reception in some places is not good, which may become a bottleneck for the implementation of the new system.
