In the information age, sharing and transfer of data has increased tremendously. Usually, the information exchange is done using open channels which can make it vulnerable to interception. The threat of intruder accessing secret information has been a continuing concern for data communication experts. One of the ways of protecting the data is by use of images. This research tries to explore the use of public images for secure communication. Novel algorithms were developed for data hiding and data encryption using public images. Initially a method for hiding classified data in images based on a password is introduced, which is further improved into a data encryption technique. Further, two more techniques were proposed for data encryption using the parity block of the public image. Simulation results showed that ciphered gray scale images have flat histogram with entropy almost equal to eight and a correlation between pixels in all directions which is almost equal to zero. The proposed stream encryption techniques are also highly sensitive to the starting pixel of the block. Both the encryption techniques have a simple structure and can generate a key stream faster than other generators.
