Study of Qualitative and Quantitative Metric for Pixel Factor Mapping and Extended Pixel Mapping Method
No full textIn this paper, an approach is presented to investigate the performance of Pixel Factor Mapping (PFM) and Extended PMM (Pixel Mapping Method) through the qualitative and quantitative approach. These methods are tested against a number of well-known image similarity metrics and statistical distribution techniques. The PFM has been performed in spatial domain as well as frequency domain and the Extended PMM has also been performed in spatial domain through large set of images available in the internet
Hiding & Analyzing Data in Image Using Extended PMM
No full textAbstractInternet technologies are now charring a vital role in our day to day life. It has the advantages along with the disadvantages also, which in term generates the requirements of information hiding technology for maintaining the secrecy of the secret information. Extensive amount of work has been carried out by different researchers in this field. In this paper, a novel special domain image Steganography method has been proposed which has been design based as an extension of the PMM method

Biometric Steganography using Variable Length Embedding
No full textRecent growth in digital multimedia technologies has presented a lot of facilities in information transmission, reproduction and manipulation. So the concept of information security is one of the superior articles in the present day situation. The biometric information security is one of the information security mechanisms. It has the advantages and disadvantages also. The biometric system is at risk to a range of attacks. These attacks are anticipated to bypass the security system or to suspend the normal functioning. Various hazards have been discovered while using biometric system. Proper use of steganography greatly reduces the risks in biometric systems from the hackers. Steganography is one of the fashionable information hiding technique. The goal of steganography is to hide information inside a cover medium like text, image, audio, video etc. through which it is not possible to detect the existence of the secret information. Here in this paper a new security concept has been established by making the system more secure with the help of steganography along with biometric security. Here the biometric information has been embedded to a skin tone portion of an image with the help of proposed steganographic technique
