OBJECTIVES
Overview of different stegnographic algorithms and comparing them in means of speed and quality of hiding.
Testing the efficiency and accuracy of hiding the data through algorithms using different software.
EXISTING SYSTEM
Earlier cryptographic technique is used to send secret messages and this can be done through some standard algorithms.
No Security
No Integrity
No Authentication
PROPOSED SYSTEM
By implementing LSB technique if we are sending message there is no possibility of hacking .
The hackers may thought that we have send just a picture they don’t know we have hidden the message inside the pictures.
Sender Side
The sender A transmits a message to the recipient B by ciphering the data or information in a cipher text format.
The sender A would embed the cipher information in the image by creating a stego file name and encode the stego file by creating password to the stego file and send to the recipient B.
LSB INSERTION
Replaces least significant bits with the message to be encoded
Most popular technique when dealing with images
