Robust image watermark embedding and extracting method and system based on deep learning

Abstract

The invention discloses a robust image watermark embedding and extracting method and system based on deep learning. The method comprises: 1, collecting image data and dividing the image data into a training set and a test set; 2, obtaining a carrier image vector; 3, obtaining a watermark image by using the watermark embedding network, and calculating the distortion loss of the watermark image; 4, converting the watermark image into a lossy watermark image; 5, inputting the lossy watermark image into the watermark extraction network, extracting watermark information and calculating information extraction loss; 6, inputting the carrier image vector and the watermark image into a discriminator, and calculating the difference between the carrier image vector and the watermark image; 7, repeating the steps 2-5 by using the test set to calculate the robustness and imperceptibility of the watermark of the test set; 8, adjusting corresponding parameters according to the overall loss, repeating the steps 3-8 until the imperceptibility of the robustness watermark image of the test set watermark reaches a threshold value, and completing the training; and 9, carrying out watermark embedding and extraction by using the trained network. The invention further discloses a system using the method.

Description

technical field [0001] The invention belongs to the field of information security technology and deep learning, and relates to a neural network-based digital image watermarking technology, in particular to a deep learning-based robust image watermark embedding and extraction method and system. Background technique [0002] With the rapid development of the Internet and multimedia technology and the maturity of social networks, the sharing and dissemination of digital data has become extremely easy, bringing great convenience to people's work, life and entertainment, but illegal copying, forgery, malicious tampering, Illegal dissemination and other acts have seriously violated the legitimate rights and interests of digital product owners, so the copyright protection of digital products is a problem that needs to be solved urgently. Digital watermarking technology is a technology that embeds specific watermark information into digital images, audio, video, text and other carri...

Problems solved by technology

These two points are called the invariance of the histogram. This feature makes the histogram-based watermarking method more robust, but the embedding capacity is much lower than other methods.
