摘要

As digital tools are in abundance, forging event-related certificates or replicating them has considerably become very easy these days, which at times reduces the quality of well-deserved certifications. Many ways are offered by businesses and organizers to reproduce sham certificates that look similar to the real ones. The authentication of credentials is made extremely difficult for companies by this, thus posing the most serious barrier to business and employers in verifying certain employees’ skills and achievements. In this paper, a novel solution is proposed based on merging the advantages of blockchain technology with the Interplanetary File System. In our scheme, the certificate data is persisted securely over IPFS, generating a unique hash for each certificate. This IPFS hash, along with a digital signature with the issuer, is stored over the blockchain. Some of the inherent core properties of blockchain—immutable, decentralized, and transparent—find immense application in enhancing security and reliability aspects of the system. Blockchain and IPFS are combined to issue and verify processes for digital certifications in a brand new, secure, and highly efficient system, making an effective solution to the global problem of fake certificates.
