Denso QR code: Increasing the amount of information with color: Strengthening security
Denso Wave: “SQRC”
DENSO WAVE recommends using “SQRC (with reading restriction function)”.
“SQRC” contains “two types of information: public information and non-public information”.
However, it cannot be determined visually.
“SQRC”: Non-public information
Non-public information is available only for “SQRC”.
It can be read only with a specific code reader (encrypted).
“SQRC” can only be issued by Denso Wave’s code generation engine.
Non-public information: field of use
Feature points extracted from face photos can also be recorded in the private part of SQRC.
A face recognition system using this system has been adopted for Kagoshima Bank’s field trials and office entrance / exit management.
Take a picture of yourself with a camera installed at the entrance of an ATM or office
Matching information with feature points of face photos stored in SQRC
If they match, it will be recognized as the person.
The advantage of this system is that face authentication is possible without connecting to the Internet.
There is also a sense of security because personal information is not stored in the cloud.
