A blockchain-based application which will automatically generate certificates as well as validates them. The data will be authenticated, reliable and unchangeable. It offers ease of determining whether a document is authentic or not and also checking the integrity and originality with the help of distributed technologies like IPFS and Ethereum smart contracts.
With the use of distributed technologies like IPFS and Ethereum smart contracts, our system makes it simple to determine whether a document is real and to validate its integrity and originality. The participants which interact with our smart contract are as follows:
a) College: The College serves as the issuing authority for certificates. Any organisation that wants to issue a certificate can be this entity. Only one or more certifications can be issued by a college or certificate issuing body in the system. It will also contain a phase during which the College will issue certificates after validating and authorising the information.
b) Student: Digital documents will be available for students to download and read. Students also obtain the ID of the document that was provided to them, which may be utilised in the future.
c) Company: With the use of the document's ID, the company will be the user who has access to information about the document's originality, validity, and integrity.
In the initial screen, the user has the opportunity to produce or validate certificates by browsing via the navigation bar.
The issuer of the certificate will be prompted to fill up their certificate form first. The issuer will be prompted to fill in the data of the various fields based on the number of fields. That data will be grabbed by our system and appended to the pre-inserted template.
For the Document, a preview will be created. IPFS will conduct its hashing process and save it if the issuer accepts it. The same hash will be sent to the Blockchain Node, where the issuer must accept the Document Generation costs in Metamask before it is recorded in the Blockchain.
The user may then upload it and have it forwarded to their relevant email address, along with the certificate ID and a link to preview the certificate.
Now follows the verification section, where the verifier may check the legitimacy of a candidate's certificate by entering the certificate Id given by the issuer.
If an issuer gives a fake Certificate Id, the system will show that no other certificate with the same Id exists.
After verification, the verifier can look at the certificate to double-check the candidate's information and certify his or her qualifications.
