Enhancing the Information Security in Web Stegnography

In the era of information technology a large amount of digital information is distributed over the Internet in the form of videos images text and audio. The main purpose of widespread distribution enables users to share knowledge between one another. As a result data transmission and information sharing are effected due to malicious activities. Different techniques exist to protect user authentication data privacy and copyrights. Two main techniques that improve security and data protection are Cryptography and Steganography. Cryptographic algorithms convert the secret message from plain text into cipher text then the message is sent over the communication channel. Steganography hides a secret message inside the carrier media. This book will investigate different Steganography algorithms and present technique to embed text message in HTML carrier file by using an encryption algorithm to secure the secret message to be sent. The proposed model hides secret data in the HTML file by applying various properties into tag attribute by inserting data in name attribute in the HTML file. In addition the suggested model can be applied in both XML and HTML languages.
