Spatial Domain Block Based Blind Image Watermarking for Hardware Applications

Internet revolution led to a vast growth in multimedia applications. So, it has turned to be a common practice to copy, transmit and distribute digital data and this, in turn, resulted in using the resources of data illegally and users who are not authorized hack by using such applications.Digital watermarking is regarded as one of the proposed solutions, which is suggested for copyright protection. This research accentuates the digital image watermarking, which protects the image by means of hiding a watermark image in an original image to demonstrate legal ownership.This paper suggests a new method of embedding and retrieving a watermark image besides the works within the (spatial domain) of digital images in which an invisible watermark image is embedded. By using a secret key to encrypt the watermark image for the sake of more security and implementing the block based spatial watermarking method embeds to the watermark to achieve a good robustness against many attacks. MATLAB has been used to perform and implement this work.”
