A Three Dimensional Model for Image Based Information Security

Images not only represents the information itself but also work as the carrier to keep the information in it. These kind of images work as the cover objects to hold secret communicating information over public network. But steganography itself is not efficient to provide effective security. To attain higher degree, in this work a three dimensional model is defined to improve the communicating data capacity, reliability. To achieve this information cryptography, compression approaches are combined with steganography. To obtain image cryptography bit transformation scheme is used in this work. To perform the compression bit encoding scheme is suggested in this work and finally to hide the information data, LSB scheme is used. As the complete work is based on mathematical formation and operators, effective data retrieval is obtained from stegano image. The results are applied on real time images and the analysis of work in performed based on MSE and PSNR values.
