,This project "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 with in an image by changing Least Significant Bit to be the message bits. Then the image can be transmitted through Network.
LSB based Steganography 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 transaparent. Hence there are a number of LSB based steganography techniques in the passive warden model as it difficult to differentate cover-images from stegoimages, given the small changes that have been made.
The index terms used in this project are
LSB Technique.
Transmission.
Image Viewer.
Here using LSB technique, the information is hidden in the least significant bits of the image data. By means of server sockets, the image containing information transmitted to network. Image viewer used to view the normal and stegoimages. Quality measures gives the variation between original and stegoimage information.
In the receiver side the same software is to be installed. When the image file is opened the software tells the user whether that contains any hiding information or not. If the image contains hidden information then client sockets will receive it.
