In this paper, we describe a novel encryption algorithm, which converts a greyscale image into a colored JPEG image. Firstly, it creates MCU (Minimum coding Unit) of the colored JPEG image from the DU (data Unit) of the greyscale image by the 8 x 8 construction matrix randomly. Secondly, it shuffles all the DUs with quantized DCT (Discrete Cosine Transform) coefficients according to a random ergodic matrix. Lastly, it rearranges the DUs as the format of the colored JPEG image and proceeds with the normal compression and encoding. The results show that the encryption speed of the algorithm is fast enough for real-time transmission and the encrypted image has almost the same size as original image after direct compression.

A novel approach is presented for edge detection using the USAN area feature at a pixel, since the USAN area characterizes the structure of the edge present in the neighborhood of a pixel. Next, Gaussian edge detector mask is applied at each pixel taking the membership function of the USAN area. The resultant is then modified and thresholded to yield the binary image. The results of the proposed edge detector is compared with other well known edge detector like Canny, SUSAN, Gradient diffusion operator etc. The edge detected image from the proposed approach seems to fare well over others. Moreover this edge detector also preserves the structure of the image unlike Canny. This is an added advantage with this approach.

3rd International conference on Intelligent Information Hiding and Multimedia Signal Processing

作者： Cai Mian Jia Jia Yan Lei Beijing Univ Technol Sch Elect Informat & Control Engn Beijing 100022 Peoples R China

H.264 video coding standard supports a broad range of application, and how to guarantee its security has already become an urgent problem. In this paper, we propose a, video encryption algorithm for H.264, which combines stream cipher algorithm with entropy coding process. It obtains video content security by encrypting codeword index to scramble the position of the codeword. Experiments show that, the proposed algorithm is, able to provide compromise between security and complexity, has little effect on compression performance. It's believed to be applied in the fields of video conference, digital rights management, multimedia storage, etc.

7th conference on mathematics of data/image coding, compression, and encryption

Past research in the field of cryptography has not given much consideration to arithmetic coding as a feasible encryption technique, with studies proving compression-specific arithmetic. coding to be largely unsuitable for encryption. Nevertheless, adaptive modelling, which offers a huge model, variable in structure, and as completely as possible a function of the entire text that has been transmitted since the time the model was initialised, is a suitable candidate for a possible encryption-compression combine. The focus of the work presented in this paper has been to incorporate recent results of chaos theory, proven to be cryptographically secure, into arithmetic coding, to devise a convenient method to make the structure of the model unpredictable and variable in nature, and yet to retain, as far as is possible, statistical harmony, so that compression is possible. A chaos-based adaptive arithmetic coding-encryption technique has been designed, developed and tested and its implementation has been discussed. For typical text files, the proposed encoder gives compression between 67.5% and 70.5%, the zero-order compression suffering by about 6% due to encryption, and is not susceptible to previously carried out attacks on arithmetic coding algorithms.

7th conference on mathematics of data/image coding, compression, and encryption

作者： Holtz, K Holtz, E Kalienky, D Autosophy San Francisco CA 94108 USA

Multimedia data may be transmitted or stored either according to the classical Shannon information theory or according to the newer Autosophy information theory. Autosophy algorithms combine very high "lossless" data and image compression with virtually unbreakable "codebook" encryption. Shannon's theory treats all data items as "quantities", which are converted into binary digits (bit), for transmission in meaningless bit streams. Only "lossy" data compression is possible. A new "Autosophy" theory was developed by Klaus Holtz in 1974 to explain the functioning of natural self-assembling structures, such as chemical crystals or living trees. The same processes can also be used for growing self-assembling data structures, which grow like data crystals or data trees in electronic memories. This provides true mathematical learning algorithms, according to a new Autosophy information theory. Information in essence is only that which can be perceived and which is not already known by the receiver. The transmission bit rates are dependent on the data content only. Applications already include the V.42bis compression standard in modems, the gif and tif formats for lossless image compression, and Autosophy Internet television. A new 64bit data format could make all future communications compatible and solve the Internet's Quality of Service (QoS) problems.

The suggested device includes a spatial light modulator (SLM) allowing varying the polarization state of an input illumination source. Attached to the SLM a sub wavelength grating is placed per each pixel of the device. This grating is used to encode the input information. The decoding is done by another sub wavelength grating. When the two gratings are attached a variation of the energetic efficiency between the two polarization states occurs. The polarization ratio encrypts the spatial information strewn. The sub wavelength grating are hard to copy and thus high encryption capability is obtained.

mathematics of data/image coding, compression, and encryption V, with Applications

Interferograms obtained from Fourier transform spectrometers (FTS) can be used to obtain high resolution optical spectral measurements. Accompanying high resolution spectra is the resulting large date volumes. This paper describes efforts directed at defining a predictor that will result in efficient lossless coding of interferograms. Interferograms generally contain informational redundancies that can be exploited by lossless coders. In addition, many interferograms show regions exhibiting short term periodicity. The short term periodicity is derived by taking the Fourier transform of the points preceding the desired prediction point. Prediction residuals are then losslessly coded with the Rice entropy coder. Compared with interferograms compressed with the Rice coding algorithm, the proposed predictor shows improved compression in most cases.

4th conference on mathematics of image and data coding, compression, and encryption

In this work, we extend arithmetic coding and present a data encryption scheme that achieves data compression and data security at the same time. This scheme is based on a chaotic dynamics, which makes use of the fact that the decoding process of arithmetic coding scheme can be considered as the repetition of Bernoulli shift map. data encryption is achieved by controlling the piecewise linear maps by a secret key in three kinds of approach: (i) perturbation method, (ii) switching method, and (iii) source extension method. Experimental results show that the obtained arithmetic codes for a message are randomly distributed on the mapping domain [0,1) by using different keys without seriously deteriorating the compression ratio, and the transition of the orbits in the domain [0,1) is similar to the chaotic dynamics.
