Steganography Project Ideas How To Return It

Data t hat has been encry pted, although unreadab le, still exis ts as data.

It serves as a better way of securing message than cryptography which only conceals the content of the message not the existence of the message.

Original message is being hidden within a carrier such that the changes so occurred in the carrier are not observable.

This paper also analyses the performance of some of the steganography tools.

Steganography is a useful tool that allows covert transmission of information over an over the communications channel.

Combining secret image with the carrier image gives the hidden image.

This paper will take an in-depth look at this technology by introducing the reader to various concepts of Steganography, a brief history of Steganography and a look at some of the Steganographic technique.

Steganography on the Internet Cover Image Stego Image After implementation of this technique if we take a look on the histogram of both the images cover image and stego image respectively we will find both are very different from each other.

The following figures show the histogram of cover image and stego image.

INTRODUCTION Internet users frequently need to store, send, or receive private information.

The mo st commo n way to do this is to transform the data into a d ifferent form.

The resulting data c an be understood only by those who know how to return it to its original form.

This method of protecting information is known as encryption.

A major drawback to encryption is that the exi stence of data is no t hidden.
