| Abstract | ||
| The manual process of issuance and validation of academic documents in Iraq has long been frustrating and time-consuming, risking the students losing their hard-earned certificates. It is clear that this calls for a new and unconventional technique to upgrade this archaic system. This is where innovation in blockchain technology provides a powerful, extendable, and private solution for processes of certification. Blockchain is a decentralized database or distributed ledger recording transactions or digital events across participating parties who have executed the transactions. With this understanding, we have come up with a groundbreaking management system for export and verification of academic certificates. In this system, we automated laborious processes of certification, reducing all the manual work necessary in certification processes and thus incredibly reducing the overall cost. The idea is straightforward; a certificate is issued by the university, it is uploaded and hashed into the IPFS for storage. A unique QR code is generated for verification. When a verifier presents a file or a QR code, our system compares the hash with those previously stored in the blockchain for its existence. If it exists, the corresponding certificate is retrieved from the IPFS while an absent hash will result in denied request. By leveraging the power of blockchain technology, our system ensures that academic documents are securely and efficiently validated; a means of freeing up time and resources of institutions. Our proposed solution aims to improve the efficiency and security of academic document issuance and verification in Iraq. | ||
