The work analyzes the methods and technologies used to develop Web services, discusses the foundations of steganography, the principles of embedding digital watermarks into images, requirements and peculiarities of implementation, noted the drawbacks of modern analogue embedding of digital watermarks. The article investigates a web service for embedding digital watermarks in bitmap images and removing them. The web service implements an embedding algorithm similar to the Koch and Zhao algorithm, but differs in that the information is placed in the spatial area of the image, embedding information is performed by changing the brightness of the pixels. Developed a web service for embedding DWM in the image. The structure of the web service, its client and server side are described in detail. The interaction between the client and the server in the system takes place via HTTP protocol. The customer part is responsible for the ability of users to interact with software products. Here information is displayed, data is collected and processed and requests are generated, which are then sent to the server for further processing. The interaction between the user and the client is due to the user interface. The user interface in the web server is built thanks to the hypertext markup language HTML, cascading style sheet CSS and JavaScript. The server part of the developed web service is responsible for data processing, saving files, embedding the DWM in the image or removing it.
