“…Other similar work based on this approach has recently been proposed (Ahmed et al, 2010) where the authors calculate and record a vector of 4-bits called "Perturbation information". This additional transmitted information has the same dimension of the extracted features.…”

“…Generally, the image authentication schemes can be classified into two catego− ries: signature−based schemes [7][8][9][10] and fragile water− mark−based schemes [11][12][13][14][15][16][17][18]. In a signature−based scheme, the given image is processed by using the hash function and the hashed result is encrypted by using the public key cry− ptosystem to generate the digital signature.…”

A novel image authentication scheme for the compressed images of block truncation coding (BTC) is proposed in this paper. In the proposed scheme, 1-bit authentication data is generated from the quantization levels of each image block. Multiple block permutations are generated by using the random sequences induced by the selected random number seeds. Multiple copies of the authenticaiton data are embedded into the bit maps of BTC-compressed image blocks based on the block permutations. Experimental results show that the proposed scheme achieves good detecting accuracy while keeping good image quatiy of the embedded image.

“…Image hashing techniques use data from different domains such as DCT coefficients [5], Wavelet transform coefficients [19] and Fourier transform coefficients [13], [15], Daubechies wavelet transform [3] to generate the signature for image authentication. A digital signature is an encrypted form of the whole data generated from original data.…”

“…The secret key is used randomly modulate image pixels to create a transformed feature space. A 4-bit quantization scheme is employed to decrease the size of the hash [19]. Harsh Kumar Sarohi et al have presented perceptual hashing scheme for content based image retrieval.…”

Authentication is one of the image security issues solved by hash function and another one issue is providing security for illegal manipulation of digital image is solved by an encryption. An optimized hybrid image security mechanism for authentication and secrecy of images by means of Particle Swarm Optimization (PSO) in daubechies4 transform is illustrated in this paper. This mechanism provide solutions to the issues such as authentication, robustness, security and statistical attacks. The PSO technique is employed to select feature vectors to form the image hash and select high energy coefficients for partial encryption. The shuffling of bits , coefficients and blocks of an image is performed by interweaving technique. The Completeness of Signature (CoS) is used to recognize the image as authentic or unauthentic. The image quality distortion is computed with help of image quality index metric(IQIM) with respect to three factors namely loss of correlation, luminance distortion, and contrast distortion. The experimental results are computed with respect to CoS, IQIM, PSNR and correlation coefficient andpresented to demonstrate the efficacy of the proposed scheme.
