Title:
SECURE ENCRYPTION METHOD AND SYSTEM FOR FACE DATA OF DOOR ACCESS CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/007095
Kind Code:
A1
Abstract:
A secure encryption method for face data of a door access control system, comprising the following steps: S1: acquiring original face image data of a door access control system, and determining a region to be encrypted according to the position of the face in an image; S2: extracting image data of a pre-encrypted region in a face image, and obtaining a sub-image to be encrypted; S3: extracting face feature data in the sub-image to be encrypted, and generating a first processing matrix; S4: according to a bit plane, performing layering on the sub-image to be encrypted, and outputting a corresponding three-dimensional matrix as a second processing matrix; S5: separately performing encryption operations on the first processing matrix and the second processing matrix, and obtaining encryption matrices corresponding to the first processing matrix and the second processing matrix, respectively; and S6: performing encryption processing on the sub-image to be encrypted by using the encryption matrices, and obtaining encrypted face image data. The described secure encryption method improves the security of face image data of the door access control system.
