“…With this key space, it is possible to generate very large number of keys which addresses the challenge of revocability. Also in the proposed scheme the expected entropy of transformed biometric template stored using chaotic maps is about 0.9991 [67][68][69][70][71][72][73][74][75][76], which is close to the theoretical value (=1). This property provides privacy and security by providing it impossible to guess the keys.…”

Modern biometric technologies claim to provide alternative solution to traditional authentication processes. Even though there are various advantages of biometric process, it is vulnerable to attacks which can decline its security. Towards addressing these concerns and improving public confidence, Biometric Cryptosystems and Cancelable Biometrics represent emerging technologies. This paper presents a comprehensive survey of Biometric Cryptosystems and Cancelable Biometrics along with the open issues and challenges. A new approach is proposed to address these open issues and challenges based on Cancellable Biometrics using chaotic maps, which are known to posses desirable properties of pseudo randomness, high sensitivity to initial conditions and very large key space.

Voting is vital part of democratic country as it allows citizen to choose their own government. Government plays important role in progress of each country. Result of election is good if most of the people votes. In today's digital world, it is necessary to have secure online voting system at place which will save voter's time and motivate citizen to vote. Secure authentication is the main issue in online voting system. The authentication module should allow authentic voter to cast their vote. Even though secure authentication is provided, someone having access to authentication database may use it to get authentic entry into the system. Research in this paper shows new and secure authentication module which provides confidentiality to authentication database so that no one can use the authentication database to pass through the system. We have achieved this using PIN based image secret sharing.

“…The shares of Visual Cryptography are printed on transparencies which need to be superimposed. A Visual Cryptography method proposed by T. Monoth et al, [7] uses random basis column pixel expansion technique. The encoded shares are further encoded into number of sub shares recursively which is computationally complex.…”

Steganography is the art and science of writing hidden messages in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message. It is a form of security through obscurity. The word Steganography in the modern day usually refers to information or a file that has been concealed inside a digital Picture, Video or Audio file. Essentially, the information-hiding process in a steganographic system starts by identifying a cover medium's redundant bits. The embedding process creates a stego medium by replacing these redundant bits with data from the hidden message. In this paper a new type of cryptographic scheme is proposed, which can decode concealed images without any cryptographic computations. The scheme is perfectly secure and very easy to implement. This is extended into a visual variant of the k out of n secret sharing problem, in which a dealer provides a transparency to each one of the n users, any k of them can see the image by stacking their transparencies, but any k − 1 of them gain no information about it.
