Image data secure transmission method and device, processing equipment and storage medium

Abstract

The invention discloses an image data secure transmission method and device, processing equipment and a computer readable storage medium, and the method comprises the following steps: S01, modifying an original picture to generate an adversarial sample picture; S02, comparing the original picture with the adversarial sample picture to generate difference data; S03, respectively encrypting the adversarial sample picture and the difference data, and independently transmitting the adversarial sample picture and the difference data; S04, after receiving the encrypted adversarial sample picture and the difference data, respectively decrypting the adversarial sample picture and the difference data; and S05, restoring the decrypted adversarial sample picture according to the decrypted difference data. According to the method, the adversarial sample picture data and the difference data are encrypted and transmitted respectively, so that the difficulty and the cost of correctly restoring the original picture by a stealer are improved.

Description

technical field [0001] The present invention relates to computer data security, and specifically relates to a method, device, processing device, and storage medium for realizing secure transmission of image data using an adversarial example. Background technique [0002] In Internet / mobile Internet applications, there is a large demand for image transmission, such as portrait photos and ID card photos used in identity verification. These image data involving personal privacy have a huge risk of being intercepted and stolen during transmission. Stealers can use stolen data to carry out illegal and criminal activities, such as using portrait photos to deceive face recognition systems, using information on ID card photos to forge ID cards, etc. [0003] At present, the image encryption algorithm with a key is generally used to solve the problem of secure image transmission. The image is encrypted with an encryption key for transmission, and decrypted with a decryption key at t...

Problems solved by technology

To a certain extent, this method can ensure that the original image will not be identified and copied, especially when the time provided by the virtual seal or the system time is used as a parameter to encrypt the image coordinate pixels. The encryption method is complicated and is not applicable to ordinary images.
