Hiding Data Using Efficient Combination of RSA Cryptography, and Compression Steganography Techniques

Data compression is an important part of information security because compressed data more secure and easy to handle. Effective technology creates efficient, secure, easy-to-connect data. There are two types algorithm techniques, lossy lossless. These technologies can be used in any format such as text, audio, video, or image file. The main objective this study was reduce the physical space on various storage media time sending over Internet with a complete guarantee encrypting hiding it from intruders. Two techniques implemented, loss (Lossy) without (Lossless). In proposed paper hybrid increases input encrypted by RSA (Rivest-Shamir-Adleman) cryptography method enhance level executing lossless compacting Steganography methods. This technique decrease amount every transmitted aiding fast transmission while using slow internet take small different media. plain text Huffman coding algorithm, also cover Discrete wavelet transform DWT based that compacts through order image's dimensions. least significant bit LSB will then implant compacted image. We evaluated system criteria percentage Savings percentage, Compression Time, Ratio, Bits per pixel, Mean Squared Error, Peak Signal Noise Structural Similarity Index, Speed. shows high-level performance methodology compared other systems use same methodology.
