Abstract

With the rapid growth of communication/transaction over internet and continuous efforts by eavesdroppers or Cyber attackers, there is a continuous need for new strong alternative algorithm. Techniques for information hiding are becoming increasingly more sophisticated and widespread. The primary goal, for designing such algorithms, is to provide security. However, performance and implementation ease and execution time are other factors that make an algorithm more usable. An improved encryption model, which is an extension of an existing algorithm based on Unicode and colours map can be used & Steganography using indiscrete wavelet transform (HCSSD) is proposed. The cipher text generated by this method can be varying in size as the plaintext and will suitable for practical use in the secure transmission of confidential information over the internet.
