“…The coefficients are encrypted with the Advanced Encryption Standard ͑AES͒ as proposed in Ref. 4. Similarly, the more watermarked coefficients are in the low-frequency bands, the more robust the watermark is to signal processing operations ͑compression, noise, filtering, etc.͒.…”

“…is used as the watermark algorithm. To obtain a trade-off between the security and robustness, the coefficients in the highest level frequency bands ͑LL 4 ,HL 4 ,LH 4 , and HH 4 ͒ should be encrypted, and the coefficients in the second highest level frequency bands ͑HL 3 ,LH 3 , and HH 3 ͒ can be watermarked.…”

“…However, until now, no solutions have been reported. In the past decade, some partial encryption algorithms have been reported that encrypt only some significant parts of the media data, such as the significant frequency bands, bit planes, and/or coding passes in JPEG2000 images, 4,5 the motion vectors or discrete cosine transform ͑DCT͒ coefficients in MPEG2 streams, 6,7 and the intraprediction modes and/or DCT coefficients in advanced video coding. 8,9 Similarly, media watermarking often embeds watermark information into parts of media data, such as the dc or ac's in DCT blocks, 10,11 and the wavelet coefficients in middle frequency bands.…”

“…The selective encryption of significant bit-planes of wavelet coefficients in high and low frequency reduces the encryption data ratio to less than 20% and encryption time ratio deducted to less than 12%. This scheme is tough to various attacks such as plaintext attack and brute-force attack and not to compression ratio [8].…”

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.

In this paper, we propose two format-compliant encryption schemes for JPEG2000, which preserve the syntax of the original codestream and do not introduce superfluous markers into the encrypted bitstream. The proposed efficient scheme randomly encrypts either low or upper half bytes of those randomly selected bytes in Codeblock Contribution to Packets (CCPs). The secure scheme encrypts both low and upper half bytes and can protect the nearly whole codestream except for the header information. The proposed schemes can provide efficient, secure, scalable and completely format-compliant protection of JPEG2000, which is proved by lots of experiments.
