Embodiment Construction

[0053] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0054] refer to figure 1 , the embodiment of the present application provides a method for detecting image steganography, including steps:

[0055] S1. Obtain the picture to be detected;

[0056] S2. Determine whether the format of the picture is a preset format;

[0057] S3. If yes, acquire the dimensions of the image matrix of the picture;

[0058] S4. Determine whether the channel information of the picture has changed according to the dimension;

[0059] S5. If the channel information of the picture does not change, divide the picture into blocks to obtain multiple...

Abstract

The invention discloses a picture steganography detection method and device, computer equipment and a storage medium. The method comprises the following steps:; after a picture to be detected is obtained, the picture is judged to accord with a preset format firstly, then channel information of the picture is judged not to be changed, then the picture is partitioned, byte codes of three primary colors of the partitioned picture are subjected to a series of calculation, and then the sizes of the byte codes corresponding to the three primary colors are compared, so that whether steganography exists in the picture or not is judged. According to the method and the device, whether the uploaded picture has steganography or not can be quickly and accurately detected.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method, device, computer equipment and storage medium for detecting image steganography. Background technique [0002] Steganography is a technology about information hiding, that is, a skill and science that prevents anyone other than the planned recipient from knowing the transmission of information (not just the content of the information). Steganography and cryptography are two of the core technologies in the field of information security. Both have the characteristics of easy steganography (encryption) of information and difficulty in detection (cracking) of information. [0003] With the development of the Internet, every Web site relies on multimedia, such as audio, video and images. Steganography is a technique that enables the embedding of secret information into digital media without compromising the quality of its carrier. The third party is neither awa...
