Secure Image Compression Using Auxiliary Information
نویسنده
چکیده
Secure transmission of data in these days is the need of the hour. Here we have used some techniques to effectively encrypt and compress the multimedia data for transmission. Effective transmission of information is required in many fields like defence,medical field etc. In our proposed scheme the sender uses auxiliary information for compression and image reconstruction. Auxiliary information has two parts one part is useful for image compression and the second part is useful for image reconstruction. At receiver side, the original image content can be reconstructed using the compressed encrypted data and the secret key. Result shows the ratio-distortion performance of the proposed scheme is better than that of previous techniques.

Intelligent scalable image watermarking robust against progressive DWT-based compression using genetic algorithms
Image watermarking refers to the process of embedding an authentication message, called watermark, into the host image to uniquely identify the ownership. In this paper a novel, intelligent, scalable, robust wavelet-based watermarking approach is proposed. The proposed approach employs a genetic algorithm to find nearly optimal positions to insert watermark. The embedding positions coded as chr...

Within recent years the use of medical images for diagnosis purposes has become necessity. The limitation in transmission and storage space also growing size of medical images has necessitated the need for efficient method, then image Compression is required as an efficient way to reduces irrelevant and redundancy of the image data in order to be able to store or transmits data. It also reduces...
متن کاملA Novel Secure Image Coding Scheme Using Fractal Transformation
Lossy image coding by partitioned iterated function systems (PIFS), popularly known as fractal image compression, has recently become an active area of research. In this technique an image is encoded as a set of contractive transformations which represent the image compactly and produce an approximation to the original image. In this paper, we present a new application of fractal image compress...
متن کاملDither-based secure image hashing using distributed coding
We propose an image hashing algorithm that is based on distributed compression principles. The algorithm assumes the availability of a robust feature vector extracted from the image. Then a suitable dither sequence is added to this feature vector, and the resulting dithered feature vector is compressed using distributed compression principles. We prove that the dither sequence can be used to gu...
متن کاملEnhance Performance of Secure Image Using Wavelet Compression
The increase popularity of multimedia application especially in image processing places a great demand on efficient data storage and transmission techniques. Network communication such as wireless network can easily be intercepted and cause of confidential information leaked. Unfortunately, conventional compression and encryption methods are too slow; it is impossible to carry out real time sec...
