Abstract :

One of the major problems in today’s society is the tampering and altering of government records such as police case information, Aadhar card information, driving license and using such false information for obtaining various benefits such as government jobs, passports, visas, and other organizations requiring trust. This project proposes a solution to this problem using blockchain implementation. The idea is to create a block for each individual and branch their various information in these blocks and chain them together. These blocks use hashing and digital signatures as a primary security requirement. Hash values of these blocks are created using the entire contents of the block, and each block contains the hash of previous block, thereby creating a chain. The various hashing algorithms used are SHA-256, and the public-key cryptography is using RSA or ECC algorithm. If someone tries to tamper with the contents of the block, the hash values change and get disconnected from the chain. Every operation on the each of the blocks will be recorded with a time stamp, and it cannot be altered. Hence, this permissioned blockchain network of all the individuals can be used to prevent the tampering and altering of various government records such as police case records, passport records, and PAN and help various organizations such as visa verification and income tax department. This blockchain network provides a solution for all the existing problems in tampering and altering of government records. © Springer Nature Singapore Pte Ltd 2021.
