Abstract
With the development of digital media technology, the security and copyright protection of media files have become particularly important. This article proposes an encrypted digital watermark technology based on HTML5 Canvas and JavaScript, which can embed and extract digital watermarks from images in the field of front-end development. In addition, this article discusses the necessity of combining encryption technology with digital watermark technology to provide a security protection mechanism for data security. The paper then introduces in detail the process of using HTML5 Canvas and JavaScript to operate image pixels to implement encrypted digital watermark embedding and extraction and achieve covert embedding of data by modifying the Least Significant Bit (LSB) of image pixels. Finally, by comparing the visual differences of the images before and after the experiment and measuring the PSNR value of each group of experimental images, it can be concluded that the encrypted digital watermark technology can effectively hide and transmit encrypted information while maintaining the visual quality of the image and is suitable for copyright protection of images. and covert communication, etc., which have high practical application value in the field of Web front-end.
