Blockchain-Based Criminal Information Management System in Sri Lanka

Due to the current economic crisis in Sri Lanka, people's lifestyles are in difficult conditions. Due to this, crimes are increasing rapidly. The graph of criminal activities is steadily increasing in the country because of an economic crisis and the globalization of ultra-modern technology. In many industries today, blockchain applications are being explored as a secure and cost-effective method to manage a distributed database and keep track of all types of digital transactions. In Sri Lanka, the existing criminal information management system is a traditional paper-basis approach. Storing, retrieving, and updating criminal records are highly time-consuming. As a result, it causes many drawbacks. To address the drawback, our team is proposing blockchain-based technology for a criminal information management system called “CRYSIS.” Blockchain can take the position of the accumulation of criminal records with a network where criminal records information is easily accessible within the organization, secure, and cannot be altered. A P2P (peer-to-peer) network called blockchain aids in the decentralization of criminal records. As a result, to maintain a ledger to prevent a single point of failure (SPOF), and all the criminal records will be updated and validated in real-time. Because they are easily accessible and unbreakable, decentralized networks with straightforward algorithms are safe and cryptographically secured. Blockchain's peer-to-peer network facilitates the sharing of information within organizations. To ensure criminal records' confidentiality and integrity, this system will be built on the immutability feature of blockchain. By developing this blockchain-based system, the corruption of risk factors can be reduced.
