Tamper-Proof Operational Activity Tracking System

Abstract

This paper presents a Tamper-Proof Operational Activity Tracking System (TPOATS) designed to provide secure and immutable monitoring of organizational activities. The system is developed using the MERN stack framework and utilizes SHA-256 cryptographic hash chaining to ensure data integrity and prevent unauthorized modification of activity logs. Each log entry is connected with the previous hash value, forming a secure tamper-detection mechanism. The proposed system includes secure authentication, real-time monitoring, audit trail generation, and dashboard-based activity analysis. Experimental evaluation shows that the system achieves 99% tamper detection accuracy with an average log generation time of 0.25 seconds and dashboard response time of 1.2 seconds. The proposed solution improves accountability, transparency, and operational security in enterprise environments such as banking, corporate organizations, and administrative systems.
