Design of Land Administration and Title Registration Model Based on Blockchain Technology

Abstract

Land administration and title registration system is the system for storing land title information and managing<br>transactions involving land titles. Due to the sensitivity of land issues, land administration and title registration<br>system should be strong to avoid any document forgery, available all the time, and take a short time to complete<br>tasks. Thus, this study aims at designing a model for such system based on blockchain technology. The proposed<br>model is designed using UML diagrams and then tested for verification using statistical usage models (Markov<br>chains). The proposed model integrates the Integrated Land Management Information System (ILMIS) with<br>factom and bitcoin blockchains which enables encryption of information from ILMIS to get the fingerprint<br>information of each land title and store it to the blockchains. The model further encrypts the land information<br>from ILMIS when needed and then compare it with fingerprints from blockchains for verification. Such<br>implementation of the proposed model will help ILMIS to have the capability of providing tamper proof for<br>stored data, providing the self-notarization mechanism, and availability of evidence for the land title from<br>distributed databases. Furthermore, the society is expected to benefit from this study as the time and cost for<br>registering land title will decrease and the possibilities of a piece of land having more than one owner will not be<br>there.
