Image encryption system based on a nonlinear joint transform correlator for the simultaneous authentication of two users [PDF]
, 2019 We propose a new encryption system based on a nonlinear joint transform correlator (JTC) using the information of two biometrics (one digital fingerprint for each user) as security keys of the encryption system.

An RGB Image Cipher Using Chaotic Systems, 15-Puzzle Problem and DNA Computing
IEEE Access, 2019 The application of confusion and diffusion processes on the three individual components of an RGB image is not secure and efficient, so this problem needs to be addressed.

Improving the security of LSB image steganography
JOIV: International Journal on Informatics Visualization, 2019 Steganography is the technique of hiding secret data (message) within any media such as digital color image. In this paper we will merge steganography process with cryptography process in order to increase the security of the proposed method.

General Impossibility of Group Homomorphic Encryption in the Quantum World [PDF]
, 2014 Group homomorphic encryption represents one of the most important building blocks in modern cryptography. It forms the basis of widely-used, more sophisticated primitives, such as CCA2-secure encryption or secure multiparty computation.

Ad Hoc Multi-Input Functional Encryption [PDF]
, 2019 Consider sources that supply sensitive data to an aggregator. Standard encryption only hides the data from eavesdroppers, but using specialized encryption one can hope to hide the data (to the extent possible) from the aggregator itself.

Tissue factor: mechanisms of decryption [PDF]
Frontiers in Bioscience, 2012 It is generally believed that only a small fraction of the tissue factor (TF) found on cell surfaces is active whereas the vast majority is cryptic in coagulation. It is unclear how cryptic TF differs from the coagulant active TF or potential mechanisms involved in transformation of cryptic TF to the coagulant active form.

, 2021 The topic of Aadhaar links with the Indians in various ways. Aadhaar can be thought of as a digital infrastructure that has been an enabler and disabler in its ways. I exploresome of these ways through my article. I tried to question the proposition of introducing Aadhaar and carefully studied its theoretical bene?ts. Furthermore, I wish to explore the
