Cryptography techniques need some algorithms for encryption of data. Many of available encryption techniques are used for textual data, a few of encryption methods are used for multimedia data; however, this algorithms that are used for textual data may be inefficient for multimedia. The most popular symmetric key algorithms are Data Encryption Standard (DES). However, DES may not be suitable for multimedia because it consumes times. Encryption and decryption of these data require different methods. This paper proposes an encryption and decryption of data by using the nature of Fractional Fourier Transform (FrFT) in signals analysis, based on multi-order FrFT. A different indicators to evaluate the security of an encryption technique have been discussed. These indicators are: sensitivity proposed techniques for the key, the complexity of the processes, and statistical analysis. The key is formed by combination of order of FrFT. The encrypted data is obtained by the summation of different orders. Numerical simulation results are given to demonstrate this proposed method.

The usage of fractional Krawtchouk transform (FrKT) in the digital image watermarking has given better robustness by using eigenvalue decomposition [1]. The scale invariant feature transform (SIFT) is used to extract high invariance feature points then by using non-sub sampled contourlet transform (NSCT) the watermark will be embedded using extracted features [2].…”

Abstract-Digital watermarking is one of the ways to have Copyright protection for digital information. The digital watermarking scheme used for watermark embedding has to satisfy robustness property to ensure the security of the secret information hidden. The scheme presented here will support the above said statement significantly. We propose here the scheme as composition of both blind and non-blind digital watermarking technique in a process of serial watermarking. A secret binary image is embedded in the first cover image to get first watermarked image by using blind watermarking technique. Then this first watermarked image is again embedded into second cover image to get serial watermarked image using non-blind watermarking technique. To extract secret binary image, first non-blind watermark extraction technique and then blind watermark extraction techniques are used. From this composite approach and serial watermark embedding procedure, we achieved considerable fidelity and robustness against -Rotation, JPEG compression and for noises Salt & pepper, Gaussian, Speckle, Poisson and multiple noises.Index Terms-Composite scheme, Serial watermarking, First cover image, Second cover image, Serial watermarked image, Blind, Type-II Non-blind.
