Image antitheft chain method and device and electronic equipment

Abstract

The embodiment of the invention provides an image antitheft chain method and device and electronic equipment. According to the scheme, the method comprises the steps: firstly extracting a to-be-encrypted image block from a to-be-processed image after a server obtains the to-be-processed image; encrypting the to-be-encrypted image block, and obtaining an encrypted image block; finally combining the encrypted image block and an unencrypted image block obtained after the extraction of the to-be-encrypted image block from the to-be-processed image, and obtaining an encrypted image. According to the scheme provided by the embodiment of the invention, the server carries out the encryption of the extracted to-be-encrypted image block, does not encrypt the unencrypted image block, thereby saving the time in encryption operation, and improving the safety of the to-be-processed image because of the encryption operation.

Description

technical field [0001] The invention relates to the technical field of data encryption, in particular to an image anti-leeching method, device and electronic equipment. Background technique [0002] With the rise of the Internet and big data, more and more users upload images and other files on mobile terminals such as mobile phones to the network for storage. Misappropriation, leading to the disclosure of user privacy, requires a series of anti-theft operations on images stored in the network. [0003] Images stored in the network will match a URL (Uniform Resource Locator, Uniform Resource Locator). In order to prevent unauthorized third parties from accessing the image through the URL address, thereby causing the image to be leaked, at present, the prior art usually An encryption algorithm is used to encrypt the URL address to set up an image anti-leech link. [0004] However, the inventor found in the process of implementing the present invention that at least the foll...

Problems solved by technology

[0004] However, the inventor found in the process of implementing the present invention that at least the following problems exist in the prior art: although the image anti-leeching chain set in the above-mentioned manner can prevent illegal users from obtaining images to a certain extent, for the encrypted URL address, It is easier to crack it by capturing packets, etc.

Once the URL address is cracked, illegal users can directly obtain related images through the URL address, resulting in lower security of image storage
