Program Overview ：

The fingerprint Key Take control of MCU At the core , The memory stores fingerprint digital template and authentication information . The fingerprint collector collects fingerprints and sends them to MCU, USB For controller Thousand connection PC End and MCU Communication for , Perform verification and comparison operations , All operations need a unified timing control . Secure authentication encryption IC Use thousands to ensure user trust The safety of interest .

Hot spots in the industry ：

At present, network identity authentication methods are divided into single factor authentication ／ Two factor authentication ／ Multifactor authentication , The more factors, the higher the safety . The most typical way of multi factor authentication is certificate +us bke y, And fingerprints ke y+ Certificate is the most secure and reliable multi factor authentication

A convenient , Therefore, it has become the most perfect way to solve identity authentication . among Adopt financial grade security chip , It can resist various physical attacks .
