Image encryption schemes have been increasingly studied to meet the demand for real-time secure image transmission over the Internet and through wireless networks. Encryption is the process of transforming the information for its security. With the huge growth of computer networks and the latest advances in digital technologies, a huge amount of digital data is being exchanged over various types of networks. It is often true that a large part of this information is either confidential or private. The security of images has become more and more important due to the rapid evolution of the internet in the world today. The security of images has attracted more attention recently, and many different image encryption methods have been proposed to enhance the security of these images. Image encryption techniques try to convert an image to another one that is hard to understand. On the other hand, image decryption retrieves the original image from the encrypted one. In this project implementation of data encryption is done on basis of bit algorithm the scenario follow for data encryption and decryption is as follow
1. Firstly have image in which data is to encrypt
2. Enter message text which is to hide in image
3. Select particular bits of pixels of image as per algorithm and hide data in form of binary in that
4. Finally save image and get encrypted image
5. Decryption of image message is vice verse.
