Biometric data is attractive in the eld of cryptography because it uniquely identi es and authenticates an individual. The biometric data itself can also be used as a key for encryption which can later be uniquely decrypted by the same person. We discuss some of the uses of biometric data in cryptography and, in particular, its use in the Fuzzy Identity-Based Encryption scheme, a scheme which i...

The Bayesian reliability estimation under fuzzy environments is proposed in this paper. In order to apply the Bayesian approach, the fuzzy parameters are assumed to be fuzzy random variables with fuzzy prior distributions. The (conventional) Bayesian estimation method will be used to create the fuzzy Bayes point estimator of reliability by invoking the well-known theorem called ‘Resolution Iden...

In this paper, we present an improved biometric identity based encryption scheme which is based on Baek et al’s scheme. By using fuzzy extractor to construct the public key of a user, we reduce the number of exponentiations of encryption algorithm, the number of MaptoPoint hash function and the length of ciphertext from O(n) to O(1). Furthermore, we proved the proposed scheme satisfy the securi...

General automata are considered with respect to normal-ization over semirings. Possibilistic automata are deened as normal pessimistic fuzzy automata. Possibilistic automata are analogous to stochas-tic automata where stochastic (+=) semirings are replaced by possi-bilistic (_=^) semirings; but where stochastic automata must be normal, fuzzy automata may be (resulting in possibilistic automata)...

Biometric systems play an important role in authenticating the identity of an individual. Such authenticated systems are still prone to attacks and securing them is an important issue. To overcome this, biometric based authentication is blended with cryptography resulting in a framework called fuzzy vault which provides a high level of security. Fuzzy vault is a biometric cryptosystem used for ...

Urbanization, characterized by the rapid growth of cities and associated changes in social, economic, physical landscapes, has been a significant global phenomenon recent decades. As expand transform, they play crucial role shaping cultural identity projecting distinct city image. The constructed framework process comprises multi-modal image processing with Gaussian Coordinate estimation Optimi...
