A Secured Watermarking Technique With Rc5 Encryption

In the digital world, that is currently evolving at such a rapid pace, intellectual copyright protection is becoming increasingly important. This is due to digital data being particularly simple to copy and resell without any loss of quality. Digital representation and distribution of data has increased the potential for misuse and theft and thus gives rise to problems associated with copyright protection and the enforcement of these rights. The main technical approaches to address the challenge of intellectual copyright protection are digital watermarking techniques. The encryption algorithm is proposed to use a block cipher. While the proposed technique embeds watermark in the encrypted domain, the extraction of watermark can be done in the decrypted domain. Double encryption technique will be used with RC5 symmetric cipher for providing increased level of security to the digital content. Experimental results show the security as well as copyright protection of the proposed algorithm.
