Abstract

In information security, the authentication and detection of tampering and forgery are of primary concern. Data hiding or watermarking for binary images authentication is a promising approach to alleviate these concerns. Even the use of a secret static key is not secured due to various attacks. To mitigate the damage of secret key exposure, key updating signature schemes can be used. Key updating is done using a one-way function. The one-way function used in this paper is the message-digest 5 (MD5) hash function. MD5 provide a unique relationship between the input and the output hash value. An additional string of data is appended with this hash value to represent the time elapsed and hence makes the key 140-bit long, which will vary dynamically. The objective is to develop real time, reliable and secure watermarking systems, which can be achieved through hardware implementations. In this paper, we present a hardware implementation of an invisible spatial domain image watermarking algorithm with dynamic key updating for binary image. The proposed architectures were modelled, simulated and synthesised in Xilinx ISE.
