Certificate Validation using block chain
- 1. SUBMITTED BY: UNDER THE GUIDENCE OF : R.VASANTHAKUMAR Ms .S .VINOTHINI AP/CSE M.VIMALRAJ DATE : 21.06.2022
- 2. Aim To validate the digital certificate through using blockchain.
- 3. DOMAIN : BLOCK CHAIN A blockchain is a distributed database. blockchain stores information electronically in digital format. Blockchains are best known for their crucial role in cryptocurrency systems, such as Bitcoin. maintaining a transaction is very secured decentralized record of transactions.
- 4. EXISTING SYSTEM According to various researches about one million graduates passing out each year, the certificate issuing authorities are seems to be compromised for the security credentials of student data. Due to the lack of effective anti forge mechanism, events that cause the graduation certificate to be forged often get noticed.
- 5. DISADVANTAGE Less security Miss use the certificate There can be incidents where students may produce the fake certificate and it is difficult to identify them.
- 6. PROPOSED SYSTEM Our system is being proposed to issue, store and retrieve university certificates through a common portal. Companies can retrieve valid certificates of students through this portal through permission from both the student and the institution that’s hosting the certificates. The hashes of the certificates are stored in block chain.
- 7. ADVANTAGEs More secured. The certificate is hashed.
- 8. ALGORITHM Secured Hash Algorithm (SHA-2). It is used for cryptographic security.
- 9. ARCHITECTURE
- 10. LITERATURE SURVEY 1.ethereum Ethereum is an open and decentralized platform Incorruptible Secure Permanent
- 11. 2.A Secure E-Qualification Certificate System The development of the system will adopt the SOA of the eframework to meet the distributed stakeholder user case. SOA allows developers to build applications from sets of services.
- 12. 3.AUTHORIZATION AND DELEGATION ON BLOCKCHAIN This scheme is implemented in the form of smart contracts over the Ethereum platform. It enables the user to audit authorization operations and inspect how access control is actually performed.
- 13. 4. Graduation Certificate Verification Model The university, the graduate and the verifier are the three parties involved in the proposed solution in order to accomplish accurate certificate verification. Internal benefits External benefits
- 14. MODULES Certificate Upload Security and authentication module Verification module
- 15. CERTIFICATE UPLOAD To create the block chain based unmodifiable certificates, initially the university needs to get registered. Each university will be having its wallet address from which it is going to send transaction. University can be added only by the owner of the smart contract
- 16. SECURITY AND AUTHENTICATION MODULE Once added the university can access the system and can create certificates with data fields. Each created certificate will be stored in the Inter planetary file system (IPFS) which in turn will return the unique hash generated using SHA-256 algorithm. This will serve as unique identity for each document.
- 17. VERIFICATION MODULE Anyone can use this transaction id to verify. the certificate details and can view the original copy of certificate using IPFS hash stored along with data. it is almost impossible to modify this certificate or to create fake certificate with same data. Hence with this we can solve the problem of counterfeit certificates
- 19. SYSTEM REQUIREMENTS Hardware Requirements Hard disk : 1 TB RAM : 4 GB Processor : Core i3 Monitor : 15” Color Monitor Software Requirements Front –End : Java,XML Back end : Fire Base DB Operating System : Windows 10 IDE : Android Studio
- 20. CONCLUSION Various technologies have been discussed to reduce the incidence of certificate forgeries and ensure that the security, validity and confidentiality of graduation certificates, even though there are many limitations regarding the security and privacy of data. A new block chain-based system reduces the certificate forgery.
