摘要：In any communication, security is the most important issue in today’s world. In Steganography we have various techniques in different domains like spatial domain, frequency domain etc. to hide the message. It is very difficult to detect hidden message in frequency domain and for this domain we use various transformations like DCT, FFT and Wavelets etc. In this project we are developing a system in which two techniques, steganography and cryptography are combined, which provides a strong backbone for its security. The scenario of present day of information security system includes confidentiality, authenticity, integrity, non-repudiation. This present work focus is enlightening the technique to secure data or message with authenticity and integrity. In this project work, the secret message is encrypted before the actual embedding process starts. The hidden message is encrypted using Tiny algorithm using secret key and DCT technique is used for embedding and extraction file.
