An Authorship Protection Technology for Electronic Documents Based on Image Watermarking

Abstract

In the field of information technology, information security technologies hold a special place. They ensure the security of the use of information technology. One of the urgent tasks is the protection of electronic documents during their transfer in information systems, including smart systems. This paper proposes a technology for protecting electronic documents containing digital images. The main idea is that the electronic document authorship can be protected by embedding digital watermarks in the images that are contained in this document. The paper considers three cases of using the proposed technology: full copying of an electronic document, copying of images contained in the document, and copying of text. It is shown that in all three cases, the authorship confirmation can be successfully implemented. Some areas of the proposed technology application are described, including augmented reality applications. Computational experiments are conducted with robust watermarking algorithms that can be used within the technology. A scenario of technology implementation is proposed which provides for the joint use of different class algorithms.

The second one consists of a series of transposed convolutional layers with a kernel (2, 2), a concatenation with the corresponding tensor from the first part of the network, and two subsequent convolutions with a kernel (3,3) and ReLU activation. The output layer for the segmentation problem is convolution with kernel (1, 1) and SoftMax activation.…”

“…Watermarks can be used both to protect the rights to a digital object [3,4] and to store additional information, for example, links to product information in promotional materials [5,6]. If the watermark is used to imperceptibly store additional information in a video stream, the ex-pected user's scenario for obtaining such information is as follows:…”
