Answer picture anti-capture method and device and computer readable storage medium

Abstract

The invention relates to the technical field of digital encryption, and discloses an answer picture anti-capture method and device and a computer readable storage medium, and the answer picture anti-capture method comprises the steps: obtaining an answer picture, and extracting the answer content in the answer picture; performing encryption processing on the answer content; and carrying out steganography encryption on the encrypted answer content to a preset template picture. According to the anti-capture method for the answer picture, the answer content in the answer picture is extracted for encryption processing, and the encrypted answer content is steganographically encrypted into the preset template picture, so the processed preset template picture does not have any change and is directly stored in the cloud. At this time, if the picture downloaded by the unauthorized party through the picture cloud storage address is a preset template picture and has no answer content, the problem that the answer content is leaked after the picture resource is captured is effectively solved.

Description

technical field [0001] The invention relates to the technical field of digital encryption, in particular to an anti-grabbing method, device and computer-readable storage medium for answer pictures. Background technique [0002] With the rapid development of the Internet industry, education has moved from offline to online, and the protection of intellectual property rights in the field of online education is also particularly important. Most of the data for answering questions in existing online education is presented online in the form of pictures, so there will be a problem of pictures being captured, that is, the pictures for answering questions are automatically exported in large batches from the picture data interface through scripts, etc., resulting in Answer picture resources are leaked, illegally used or profited. At present, most of the methods used by the industry to prevent image capture or protect intellectual property rights are to add digital watermarks to ima...

Problems solved by technology

[0004] The cost of digital watermarking is low, but the technology for image watermark removal is also very mature. Illegal users can decrypt the captured answer image resources simply by removing the watermark, and there is no way to completely guarantee the privacy of the answer image.
