Current graphical password systems implementation algorithms by digital watermarking

摘要

The paper considers current systems of user identification. The author proposes an algorithm of client-server system creation using the methods of steganography, in particular those of digital watermarking (DW) for user identification/authentication in various telecommunication systems. The use of the proposed algorithm makes it possible to create a stable system of identification/authentication and reduce the time of password memorizing and user authorization.
