Abstract

The invention discloses an image encryption method. The method comprises the steps of determining whether an original image uploaded to a data server is an image containing a biological characteristic; if so, extracting an eigenvalue of the original image and a characteristic point of the biological characteristic in the original image; changing coordinates of the characteristic point in the original image; and combining the image after the coordinates are changed, corresponding process data in the coordinate change process and the eigenvalue to generate an encrypted image. According to the technical scheme, after the biological characteristic image is uploaded to a data server, the image uploaded to the data server is subjected to encryption processing firstly, and then the encrypted image is stored in the data server. Therefore, after the data server is broken through, image information stored in the data server has a security guarantee and cannot be directly obtained, and the storedimage information can be obtained only after the encrypted image is decrypted.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to an image encryption and decryption method and system thereof. Background technique [0002] With the popularity of smart mobile devices (including smart security devices) and the development of the Internet, countless biometric authentication methods have emerged. In the early days, it mainly focused on face and fingerprint recognition, and later extended to iris recognition, palm recognition, and finger vein recognition. Existing application scenarios at least include saving the above-mentioned biological characteristics collected through the terminal device through the terminal device and uploading it to a data server for storage. In particular, it is necessary to collect and record the biological characteristics through the device terminal, and then upload and save the recorded information to the data server. [0003] At present, most of the biometric information ...
