High Efficient Data Embedding in Image Steganography Using Parallel Programming

Abstract

Steganography is the art of hiding the fact that communication is taking place, by hiding information in other information. Many different carrier file formats can be used, but digital images are the most popular because of their frequency on the Internet. For hiding secret information in images, there exist a large variety of steganographic techniques some are more complex than others and all of them have respective strong and weak points.. As embedding data in an image, is independent of one another. Parallelism can be used to achieve considerable time gain. nography, although it has made communication safe, it has its own drawbacks. One among it is time required to embed data in pixels of the image. This problem is bugging computer scientists from long time. This paper discusses a method which makes OpenMP parallel library to parallelize embedding of data, which basically reduces the time by almost fifty percent and to achieve PSNR ranging from 30 to 50 after embedding data in the pixels of the image.
