Problems solved by technology
This scheme has the following disadvantages: First, it is difficult to accurately control the mosaic effect
For example, the coding effect obtained by operations such as disorder or transformation is not stable. Sometimes some original images can be seen, and the encryption effect is not ideal; And the decoding operation is not an accurate and reversible process, and there will be deviations at the pixel level, so there may be some differences from the original image after restoration
Therefore, the existing face encryption method has low decoding accuracy, resulting in low image restoration

The embodiment of the invention provides a face encryption method and device, electronic equipment and a storage medium. The method comprises the following steps: obtaining to-be-encrypted face image data and face encryption box data; according to the face encryption box data, determining a to-be-encrypted face key area in the to-be-encrypted face image data as first face key part data, copying the face key area as second face key part data, and respectively performing first encryption and second encryption on the first face key part data and the second face key part data to obtain first encrypted image data and second encrypted image data; and packaging the first encrypted image data, the second encrypted image data and the face encryption frame data into encrypted face image data. According to the embodiment of the invention, the method and the device are simple to implement, good in encryption effect and high in face image decryption and restoration precision.
Description
technical field [0001] The invention relates to the technical field of data encryption, in particular to a face encryption method, device, electronic equipment and storage medium. Background technique [0002] With the large-scale commercialization of face recognition technology in public places such as smart security, urban transportation, smart commerce, and smart communities, the privacy protection of face information has also attracted more and more public attention and concern. In order to effectively protect In response to public privacy and social concerns about face information security, a security mechanism for face information encryption needs to be introduced into the new generation of face recognition systems. For unauthorized users, only encrypted face pictures or information can be obtained, and for authorized users, unencrypted face picture information can be easily obtained. This requires face image encryption technology to be safe, reversible, and lossless....
