摘要：Steganography is a method in which secret message is embedded into a cover image to protect it from unauthorized access. The challenge of steganography technique is to maintain a rational balance between the quality of file and size of data that can be transferred. This paper presents a secured and robust steganography method capable of embedding high volume of information in digital cover image without incurring and perceptual distortion. This method is based compression and encryption. In this method the message to be transmitted first using Lempel-Ziv-Welch compression technique and is encrypted by using and hide compress data in image using kekre’s algorithm. The proposed method is tested with different images and text of various lengths.
