Abstract

The invention relates to an image signature method and device, computing equipment and a storage medium. The image signature method comprises the steps of obtaining user feature information and a first image; processing the user feature information to obtain a plurality of color values corresponding to the user feature information; and modifying the color value of the first pixel point in a predetermined area of the first image according to the plurality of color values to obtain a second image. By using the signature method provided by the invention, the user feature information is hidden in the first image, and the reliability of right protection of the first image is improved. In addition, when the second image with a signature is displayed, information except the second image is not displayed, so that the impression of the whole picture of the image is prevented from being influenced.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to an image signature method, device, computing device and storage medium. Background technique [0002] With the gradual enhancement of intellectual property awareness, in order to realize the protection of rights such as copyright and authorship, watermarks can be added to documents, and the content of watermarks can be the author's pen name, name, website address, etc. The watermark can be covered in an important position of the image, generally as close to the edge of the screen as possible and rich in information, so as to prevent attribution and related legal issues caused by unauthorized use of the image. [0003] However, the watermark will also be displayed while displaying the file, which will affect the look and feel of the overall image of the file. Moreover, watermarks can be weakened or removed through certain technical means, resulting in low reliabili...
