INTRODUCTION

Secured Data Transmission through Network handleshiding a secret message with in an image in such a way

that others cannot discern the presence or contents of

the hidden message.

A message might be hidden with in an image bychanging Least Significant Bit to be the message bits.

Then the image can be transmitted through Network.

LSB based Stenography is perhaps the most simple and

straight forward approach. In this project we embed the message in to the least

significant bit planes of the image.

Since this will only affect each pixel by +/- 1, if at all, it is

generally assumed with good reason that degradation

caused by this embedding process would perceptually

transparent.

Hence there are a number of LSB based steganography

techniques in the passive warden model as it difficult to

differentiate cover-images from steno images, given the

small changes that have been made.

ADVANTAGES

Secure data transmission or information hiding systemhas been developed to provide confidentiality securityservice.

Second and main advantage is if the hacker wants toextract the embedded message in image file he must

and should the following algorithms:a) Algorithm to extract the message from the image (Stego

algorithm),

b) Encryption algorithm,

c) Correct password for algorithm, and

d) Message process algorithm for check integrity ofmessage.

This increases levels of protection using encryptionalgorithm, the proposed system for steganography isstronger from the attacks than any other existing system.

MODULE DESCRIPTION

There is 1 module in this Secured Data Transmission

over the Network. They are:User

User Module

The functionalities of the User module are:

A user runs application.

User selects data to process.

Application processes the data Encrypt or Decrypt data.

User sends or receives data securely.

CONCLUSION

Until recently information hiding techniques received verymuch less attention from the research community and

from industry than cryptography.

Steganography has its place in security.

It is not intended to replace cryptography but supplementit.

In this system it has given an idea to enhance the

security of system with a by combining techniques.

It can enhance confidentiality of information and ofinformation and provides a means of communicating

privately.


25/27

Here message is encrypted and then embed in imagefile with help of Steganographic system.

The system security further enhance by using password

to embed the message. This system explains a tiny fraction of the art of

steganography; it goes well beyond simply embedding

text in an image.
