Abstract

The invention provides a watermark adding method and device, a watermark recognition method and device and electronic equipment, and the method comprises the steps: processing a first image based on awatermark, and obtaining a second image; and processing the original image by using the second image so as to add the watermark into the original image. According to the invention, the watermark information is added to the original image through the second image, and then whether the image is tampered in the transmission process can be determined by extracting and analyzing the watermark information carried by the subsequent image information, so that the normal operation of each system in the network is ensured, and the security of the network is also ensured.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a watermark adding method, a watermark recognition method, a device and electronic equipment. Background technique [0002] The description of the background technology of the present invention belongs to the relevant technology related to the present invention, and is only used to illustrate and facilitate the understanding of the content of the present invention. prior art on the filing date. [0003] Image can be defined as the reproduction of things on a certain medium, such as pictures, movies, faxes, televisions and other media can enable people to obtain image information. The process of transmitting image information to other storage devices through the network is image transmission. With the rapid development of the Internet, more and more images need to be transmitted in the network. [0004] Multiple images are usually stored in the system, and users need to exchange...
