PMSChain: A Blockchain-based Prison Management System using the Ethereum Platform

Abstract

The prison system in India lags other industries, such as healthcare, in terms of automation. The existing prison management system often lacks transparency, consistency in security information, and well-defined procedures. To address this issue, we developed a system to digitize daily prison operations. The proposed blockchain-based prison management system is a comprehensive software application designed to manage activities related to prisons using a distributed ledger for efficient storage and managing information related to lawbreakers. The prison authority can have access to add, delete, or update the lawbreaker data that is collected from the police. The suggested system defines various roles for accessing the data inside the prison. Proper and timely access to data is enabled for the prison authorities. The proposed system has been implemented using the Ethereum Sepolia test net with 1000 tractions and its total transaction cost is 0.015357. Additionally, gas price, throughput, and latency has been computed for the proposed work. This system has been designed to provide secure, efficient, and user-friendly management of inmate records, scheduling, and communication. This system enables tamper-proofness, accountability and security of data by incorporating blockchain technology for secure and immutable record transaction within prison which prevents fraud, and corruption. © 2025 IEEE.
