Secured Data Transmission
ABSTRACT
Secured Data Transmission through Network handles hiding 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 within an image by changing 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.
Module Description:
There is 1 module in this Secured Data Transmission over the Network. They are:
1. User
User Module
The functionalities of the User module are:
1. A user runs application.
2. User selects data to process.
3. Application processes the data Encrypt or Decrypt data.
User sends or receives data securely
Software Requirements
A set of programs associated with the operation of a computer is called software. Software is the part of
the computer system which enables the user to interact with several physical hardware devices.
