Hiding Compressed and Encrypted Data by using a Technique of Steganography

Amrita Bhatnagar , Shweta Chaku , Monica Sainger

The steganography is a technique which hide the text data in the color and gray images .We can use different type of steganography techniques. Some Techniques are used in spatial Domain Technique. Some techniques are used in frequency Domain. Some steganography techniques are very popular like LSB, MSB and 7 bits in hiding the invisible information in various file formats images. In this paper, Steganography and Cryptography is combined for hiding and unhiding a text file into an image file. Data Compression is also used in this technique. LSB insertion technique is used for Steganography and LZ algorithm is used for Data Compression. Cryptography is done with RSA algorithm

LSB Encoding Algorithm

LSB Encoding algorithm works in binary data so firstly we have to convert our image in binary format and then embedded the message bits with cover image pixel. Each pixels least significant bit will be replaced by message bit . In this way data will be hide in cover image.
