LandChain: A MultiChain Based Novel Secure Land Record Transfer System
Amritesh Kumar, Lokendra Vishwakarma, Debasis Das · IEEE Transactions on Reliability · 2024
The process of transferring land records (LRs) and ownership between users is facilitated by a LR transfer system. This system encompasses a series of procedures, including conducting title search, establishing agreements, executing legal documentation, verifying and transferring ownership, and updating LRs. Despite its importance, the system encounters notable challenges, such as insufficient tamper-proof record-keeping, lack of system compatibility, time-consuming processes, and the presence of intermediaries and brokers leading to potentially fraudulent claims. To address these challenges, a novel solution calledLandChainis proposed in this article. TheLandChainutilizes MultiChain, consisting of MainChain and SideChain, to securely transfer LRs among users, such as buyers, sellers, land donors, and owners. TheLandChainincorporates innovative algorithms like record forwarder selection (RFS), trust establishment (TE), and record transfer and confirmation (RTC). Furthermore,LandChainverifies the legitimacy of users before transferring LRs through the verify user legitimacy algorithm. Security analysis showsLandChainis secure from double-spending, liveness, Sybil, replay, and man-in-the-middle attacks. The implementation ofLandChainis developed and tested on the docker engine platform. According to performance analysis, theLandChainreduces record confirmation latency by 18% (MultiChain) and 50% (Blockchain).LandChainalso increases throughput by 34% (MultiChain) and 45% (Blockchain) when compared to state-of-the-art approaches.
