Reducing Forgery in Land Registry System Using Blockchain Technology

Forgery of land documents is one of the major problems faced by any state government in land registration system. Even though the documents are now secured in the database, but these records can be tampered because there is no proper security and time-stamping present in the database system. To overcome this problem, the use case can be deployed using Blockchain. Blockchain being a distributed system, data is available to everyone in the network. Every block added into the blockchain is time stamped and proof-of-work is required to add the block, making the data very hard to be tampered. In this paper, we have used a private-permissioned Blockchain - Multichain, where the authority lies with the registrar making the process faster because proof-of-work [13] is not required. The implementation of land registration use-case involves recording the documents into blockchain and verifying it with the one stored in digital locker thereby reducing forgery of documents.
