Abstract
For successful business, information technology is becoming increasingly important. After all, with the help of its information system, each company organizes all internal processes, interacts with external partners, contractors and customers, government agencies. About the provision of information security a lot has already been written, but in this article the authors pay attention to one of the methods that can be used to protect against committing malicious acts directed against the company from within. The proposed method perfectly copes with the internal threat, however, as well as with the external one. The main task in this manuscript is to create a method for countering counterfeits of digital photos, and describes the algorithm for protecting the image. (c) 2017 The Authors. Published by IASE.
