Evidence Collection Reporting using Blockchain for Preserving Integrity of Digital Investigation

Abstract

In the current scenario, crime rates increase day by day. The police department plays a vital role in maintaining law and order, and to enforce safety. The project is aimed to develop a blockchain based record keeping system for crime investigation details using smart contract. This can be used to report various crime activities with much authenticity than the traditional way of maintaining records. The records are stored in the database using blockchain architecture and validation is done using proof of work. This is implemented as an online web application using python framework in which police officers can store crime details and FIR details and is managed in a distributed environment. The project interface is made user friendly so that the officials can use it without much learning. The FIR is maintained around the block chain concept in which blockchain administrators play the role of decision makers. Each block is created using finger printing and implemented using the SHA-256 algorithm.
