Secure Data on HTML Web Page using Steganography with Encryption and Compression Technique

Abstract

Many methods are used to securely transfer data, but the greatest challenge is to be careful of being detected by the intended recipient. The most famous methods are encryption and steganography. Encryption method draws the attention of third parties, but Steganography is a method to hide data inside a carrier such as Image, Audio, Video and Text without drawing any suspicion. In this thesis, the data transfer as a text medium and in more accurate HTML file was used. This method is difficult type of the steganography because text files have a small amount of redundant data to hide a secret message and the structure of the document is observe. So to make detection more difficult both encryption and steganography are used with compression in addition to them, called Secure Hiding Data on HTML Web page using Stego-Crypto- Compression Schema. The Schema has been applied in three levels, level one has been applied using encryption by ElGamal Elliptic Curve Cryptosystem, the input is a secret message and the output is a decrypt message. Level two is compression the decrypt message to generate compress message in format 0 and 1. In level three do steganography to hide the compress message in HTML file as a comment for tags. The analysis shows that
