Tencent face data encryption patent published, which can improve the security of face data

CTOnews.com news on December 21, according to the China Patent announcement of the State intellectual property Office (application no.: CN115495720A), the patent applied by Tencent Technology (Shenzhen) Co., Ltd. for "face data signature method, device, electronic device and storage medium" was authorized to be announced.

The patent summary shows that by obtaining the face data to be signed and the corresponding reference acceleration data, the two are fused to get the fused face data, and the feature coding is carried out to get the coding information. The feature of the coded information is reconstructed to get the acceleration security factor, and the hash value of the face data is obtained by hashing the acceleration security factor and face data. Based on the key corresponding to the face data, the hash value is encrypted and the signature information of the face data is obtained.

CTOnews.com learned that the application embodiment can encrypt face data combined with acceleration data, which is helpful to improve the security of face data encryption.
