Abstract: | In the period of innovation, editing, control and replicating of computerized mixed media has turned out to be predominant and a significant issue in the present situation. Computerized watermarking is one of the answers for managing this issue. It is a strategy in which example of bits are implanted into the advanced information so as not to block the real information. Subsequently it keeps up its dependability. Computerized watermarking can be connected in the assortment of utilization regions, for example, copyright security, fingerprinting, broadcasting checking, duplicate assurance and medicinal application. The principle issue is to keep up the adjustment between indistinctness, strength and limitation as expanding one factor aggressively has an impact on the other and a decent advanced watermarking framework has to be chosen. To achieve good imperceptibility, watermark should be embedded in high frequency element whereas robustness arises in low frequency component. In order to analyze and choose best encryption methods initially RC6 (Rivest Cipher 6) encryption method is employed with an embedding algorithm for generating robust watermark images. RC6 (Rivest Cipher 6) is a transformative change of RC5 (Rivest Cipher 5), intended to meet the prerequisites of the Advanced Encryption Standard (AES). Like RC5, RC6 makes fundamental utilization of information subordinate pivots. New highlights of RC6 incorporate the utilization of four working registers rather than two, and the consideration of whole number increase as an extra rough task. Even though the expansion of working registers in RC6 improves the nature of security, diminishes the rounds, and raises the throughput, RC6 is found to have an issue with the RGB computerized pictures which have an odd pixel measure. This issue occurred if the quantity of pixels does not coordinate with the division of the square so the cushioning is required. On the off chance that cushioning happens then the information size of the encryption will change newline |
