RoundImage Towards Secure Graphical Password Authentication via Rounded Image Selection in IoT
Our study aims to develop a Multi-Factor Authentication System that integrates RoundImage-based graphical password verification with Time-based One-Time Password (T-OTP) authentication to ensure secure, reliable, and observation-resistant user login. The system is designed to enhance trust, prevent unauthorized access, and reduce credential-based attacks by providing a tamper-resistant, user-friendly, and highly secure authentication framework suitable for modern digital environments, including IoT and web applications.
Transchain: Blockchain-Based Management of Allografts for Enhancing Data Provenance
Aim:
The aim of this project is to develop a secure, transparent, and tamper-proof blockchain-based system for managing allografts throughout their entire lifecycle—from donor registration to tissue processing, storage, distribution, and transplantation. The system seeks to ensure authenticity, complete data provenance, regulatory compliance, and real-time traceability by leveraging decentralized ledgers, smart contracts, and digital tagging technologies. This helps enhance patient safety, reduce fraud, and build trust among medical institutions and regulatory authorities.
