Application of Random Block Selection and Random Bit Selection in the Field of Image Steganography

Abstract

In current scenario many of the information passes through electronically for communication and information. To secure information is an important and fundamental issue. Steganography is an approach for can secure the secret data by hiding its presence in multimedia carriers (text, image, audio, and video.) during storage and transmission. Digital image are most popular object for embedding process. Steganography uses an image as the cover, Spatial Domain and Frequency Domain are two techniques for conceal information in a cover image. Spatial domain approaches manipulate the cover image pixel bit values to embed the secret information. Frequency domain techniques are complex and hard to implement. It propose an image steganography technique for secure data hiding system based on random block and random bit selection and image stenography in frequency domain using DCT and IWT Embedding Prevent the system from Steganalysis.
