According to a report on Bijie.com on August 6th, the Ministry of National Security's WeChat official account stated that in the digital age, biometric recognition technology has rapidly developed and been widely used due to its accuracy and convenience. Biometric recognition technology allows for the rapid collection, analysis, storage, and identification of facial, fingerprint, iris, body shape, and gait data, bringing significant convenience to our lives. However, the potential risks of data leakage associated with this collection should not be ignored. Publicly available cases have revealed that an overseas company, under the guise of issuing cryptocurrency tokens, scanned and collected user iris information worldwide and then transferred the data source, posing a threat to personal information security and even national security.
