Steganography for Secure Communication Using BPCS and HDWT
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 1
Abstract
Steganography is an invisible communication for hiding existence of communicated information bits. In this paper, we propose Steganography for Secure Communication using BPCS and HDWT (SSCBH). The Bit Plane Complexity Splicing (BPCS) is applied on the cover image of size 512 x 512 to generate bit planes. The HDWT is applied on each bit plane to generate four subbands. The HH subband of the cover image is used to embed the payload. The permutation process is used to generate stego key which is used to extract the payload. The payload is converted into binary form and last 4-LSB bits of each column are embedded into the HH band of cover image. It is observed that the value of PSNR is high for the payload image of size 90 x 90 for different images of cover image.
