Towards Secure Biometric Solutions: A Multifactor Authentication Framework for Facial Recognition While Protecting User Data

IET Biometrics, Volume 2026, Issue 1, 2026.
Storing raw facial images or face embeddings in an authentication database creates a persistent privacy liability. A single breach can permanently expose a person’s biometric identity. This paper presents a multifactor authentication (MFA) framework for facial recognition systems that removes this liability by never storing biometric data, in any form,

A New Technique in Rank Metric Code-Based Encryption

Cryptography, 2018
We propose a rank metric codes based encryption based on the hard problem of rank syndrome decoding problem. We propose a new encryption with a public key matrix by considering the adding of a random distortion matrix over F q m of full column ...

FPGA Realization of a Novel Hyperchaos Augmented Image Encryption Algorithm

IET Computers &Digital Techniques, Volume 2026, Issue 1, 2026.
With the rapid growth of multimedia communication, protecting image data has become increasingly critical. This article proposes a novel 3‐stage hyperchaos‐based augmented image encryption technique (3SHAIET) that utilizes a three‐stage process with chaotic systems of increasing dimensionality (e.g., six‐dimensional [6D], 8D, and 9D) to enhance ...

A Lightweight, Secure and Reliable Geographic Routing Protocol for Urban VANETs

IET Communications, Volume 20, Issue 1, January/December 2026.
This paper proposes a Lightweight Secure and Reliable Geographic Routing (LSRGR) protocol. The protocol operates in two phases: (i) a greedy forwarding strategy with location verification, which leverages key urban routing parameters to select the most reliable forwarder and employs a recovery mechanism against routing failures, and (ii) reliable route
