Decreasing the spotlights level of vector images after installation digital watermarks

Abstract

Today, steganographic methods are widely used to solve the following tasks: protecting confidential (official) information from unauthorized access; protection of copyright in intellectual property. The most widely used are methods of concealing information used as an image container, in particular a vector. This is due to the following reasons: relatively large amount of digital representation of images; lack of restrictions imposed by real-time requirements; the presence in most real images of areas of textures that have a noise structure and correspond to the embedding of information; the necessity of protecting photographs, pictures, videos from illegal copying and distribution.In the world there is an incredible number of projects, including advertising, design, website design and presentations, architectural design drawings, geographic maps, etc. The risk associated with the use of images from the Internet is enormous. However, given the high degree of anonymity, the ease of dissemination of information, a significant audience, there is a problem of copyright protection of electronic documents.For their protection, steganographic methods of embedding digital watermarks are used. An analysis of existing methods shows that for most of them, the problem of impairment of image quality in the embedded DVB is relevant. When displaying real objects on a scale (architectural structures, geographic maps, etc.), this problem is especially relevant, since a significant change in the coordinates of the points can significantly impair the quality of information about existing objects or affect their creation. Therefore, the method optimizes the method of embedding the central digital output vector in the vector image, by reducing the distortion of the image-container.
