Fort2bck: Hybrid Cryptographic Validation For Robust Healthcare Data Protection

Abstract

Fort2BCK is a robust security framework designed to address major vulnerabilities in healthcare blockchain systems, including data tampering, unauthorized access, and limitations in consensus protocols. The framework introduces a dual-layer verification mechanism that strengthens existing consensus algorithms using advanced cryptographic techniques such as RSA, ECDSA, and Zero-Knowledge Proofs (ZKPs). This additional security layer improves authentication, auditability, and resistance against malicious activities within system.
