Abstract

There are still forged documents, no clear records of past history of ownership, and the absence of verification systems that cannot be tampered with which plague land verification and the property ownership transfer in India. The current literature shows that blockchain is used to register land in a safe manner, but most studies fail to incorporate automated document verification via OCR and discuss the possibility of tokenizing fractions of ownership in a single system. The purpose of this study is to fill this gap and suggest Landsure a blockchain-based property verification and token transfer model that will guarantee transparency, immutability, and reduction of fraud. The system has automated document extraction based on Tesseract OCR, backend validation based on Node.js and MongoDB, and tokenizing ownership based on Solidity smart contracts on a private Ethereum network (Hardhat). Experimental results indicate that OCR-based verification is effective at extracting structured fields of scanned documents and smart contracts are effective at keeping ownership records which do not change, eliminating 38% of manual verification in simulated workflows. The findings reveal that OCR and blockchain integration enhance the document authenticity checks and tokenization provides transfer of ownership in a secure and traceable manner. The research incriminates the high possibility of practical implementation with further extensions to AI-based checking and publicly implemented blockchains.
