Blockchain technology in document verification
In the period of IoT, People still depend on customary techniques like paper records for issuing declarations and authoritative reports. The motivation behind why they are still using the old technique is because of the lack of knowledge in new techniques and security concerns while maintaining the digital records in the servers and limit the accessibility of the data
Numerous Institution and association also require the original certifications need to be cross-checked before issuing to the students since the documents are very important a slight variation on the certificates will arise many issues so it ought to be without mistakes. Also, the hard copies of the certificates need to be carried for verification, students need to be extra while carrying the certificates because there is a possibility of misplacing.
Many institutions are using barcode technique to identify the certificates are original or not, but nowadays these techniques are not reliable anymore. Because anyone can generate lookalike barcodes and easily manipulate the certificates
A potential answer to resolve this issue is to apply blockchain technology to store the information where the blockchain organizes and stores the information in a decentralized and secure mode that makes the information difficult to change or to remove. The Blockchain based Document Verification can be applied using the blockchain Network. In order to do this, Certificates are set on an appropriated record before issuing but uploading or storing the whole record in Blockchain is definitely not a smart idea. The most proficient technique is to store the hash of the certificates, instead of uploading the whole certificates into the blockchain network. The principal procedure is to convert each certificate into a single hash using the common technique in. The code is currently accessible on the blockchain Network. The code can be used as a verification method to identify the certificates are altered or not. Blockchain Document Verification process is achieved by hashing the code to a cryptographic mode. At the point when a business or an establishment needs to check the record submitted is original or not. The business or the institution will check to confirm that the declaration given is true or not by hashing the hash code into the cryptographic mode. If the submitted certificate is original the hash code matches and if the report contains any change the markers won’t match. This is the way the Blockchain Document Verification Process is done and can be used to verify any type of documents
