An Efficient and Secure Data Hiding Technique ? Steganography

Abhilasha Ramdas Bhagat, A. Prof. Ashish B Dhembhare

The technique to hide secret data in some carrier without any apparent evidence of data exchange is called as Steganography. The main goal of Steganography is to hide securely in a completely undetectable manner and to avoid drawing suspicion to the transmission of a hidden data. Steganography is used to secretly communicate information between people. The propose of a framework for the detection of the least significant bit (LSB) steganography with the use of digital media files as cover objects. It can compute a robust estimate of the length of a secret message hidden in the LSBs of samples for a large class of digital media contents such as image, video, and audio, in which the signals consist of correlated samples. In the traditional steganography techniques principle was either to replace a certain part of the frequency components of the carrier image, or to replace all the least significant bits of a multi-valued image with the secret data. Our new steganography uses a video as the carrier data, and we hide secret information in the bit-planes of the carrier.
