Abstract

The invention relates to the field of data processing, and provides a watermark adding method and device, computer equipment and a storage medium. The method comprises the following steps of acquiring target data to be added into a picture, performing byte conversion on the target data to obtain an original byte array; processing the original byte array based on an encode method of base64 to generate a specified byte array; according to a preset updating rule, sequentially using every three bytes in the specified byte array to perform one-to-one correspondence updating processing on the color values of the three color channels in the corresponding pixel points of the corresponding row in the picture; and filling the specified pixel points in the picture with the character length to obtain a target picture so as to complete watermark adding processing of the picture. The target data is added into the picture in an implicit manner, so that the sharing safety and concealment of the target data are ensured. The invention can also be applied to the field of block chains, and the target pictures and other data can be stored on the block chains.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular, to a watermark adding method, apparatus, computer equipment and storage medium. Background technique [0002] In order to protect still pictures, watermarking technology can be used to embed the picture to be protected with some information that can prove copyright attribution or track infringement, such information can be the author's serial number, company logo and meaningful text, etc. Wait. By adding an explicit watermark, the purpose of protecting the copyright of the picture and tracking the infringement of the picture is achieved. However, this method of adding and displaying the watermark will affect the display of the picture information, and the appearance is poor, and there are problems of poor concealment and poor security. SUMMARY OF THE INVENTION [0003] The main purpose of this application is to provide a watermark adding method, device, co...
