Abstract:  In today's world, everyone prefers submitting documents in digital format rather than in hard copy, as Digital Document Management is the current trend for submitting documents to officials, authorities, and others. This scenario sparks curiosity in verifying documents in digital settings. When submitting documents online, it is important to provide clarifications about their security, novelty, trustworthiness, and other relevant aspects. On the flip side, the user must ensure they have additional privacy measures in place when submitting documents online for further processing. The suggested system addresses the challenges of Security, Novelty, Integrity, Access Control, and Durability to find solutions to the mentioned problems and queries. Blockchain is a term that encompasses all industries today, whether government or non-government, as it extends its influence across various sectors to demonstrate its importance universally.

The banking industry also utilizes Blockchain to offer security to account holders. The suggested program utilizes Blockchain technology for document verification, offering the highest level of security for users to digitally submit documents to authorities. The authorities can verify the documents intelligently while adhering to security protocols. The Blockchain system generates necessary data as a Block, with the first block being called the Genisis Block, guiding subsequent blocks sequentially without interference. The Miner Verification process in Blockchain checks the records in a Block against incoming records to ensure uniqueness before allowing them to be added to the next block. In the current system, records are blocked by Miner Verification process if they are already in the block. However, in this new system, Miner Verification is a voluntary process where volunteers physically verify Blockchain Miner verification process. More details will be provided later on. Every block in the Blockchain has a unique identity represented in cipher form through the use of SHA, a strong one-way encryption algorithm with a 256-bit encryption process. The whole procedure of the suggested system guarantees a secure and smart document verification scheme using Blockchain technology with effective innovation.

Keywords: Blockchain, Crypto Hashing, Document Check, Integrity Analysis, Secure Hash Algorithm, Cloud Interface, Miner Verification Process, Volunteer, Genisis Block.
