Abstract

Development of digital watermarking technology has enabled the copyright protection and content authentication of digital multimedia data. Watermarking technique for digital images uses either spatial or frequency domain method. This paper describes a discrete cosine transform (DCT) based blind watermarking method for digital images and its hardware implementation using BeagleBoard. Experimental results show that the developed method is robust against various attacks and potentially compatible with JPEG compression.
