Data Hiding Using Blind Algorithm of Steganography
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 9
Abstract
The process of hiding messages or information within other non-secret text or data is called steganography. Steganography may be text, image, audio or video steganography. Digital image Steganography is popular because images have high data hiding capacity and are used for transmission. We propose and implement a data hiding method using blind algorithm of steganography which hides secret data in colour images by maintaining good visual quality and takes very less time in hiding and extraction of message. This method is based on third level two dimensional discrete wavelet transform (DWT) set by Haar wavelet. The main advantage of blind steganography methods is that there is no requirement of original image in extraction process which makes secret communication undetected by third party user or any steganalysis tools. In order to obtain a better imperceptibility result secret message Huffman encoding is used. The security of communication is also increased by these modifications. The experimental activities are carried out by using software MATLAB R2014a.
