Block Chain Based Certificate Validation

Abstract

The "Blockchain Based Certificate Validation"
system revolutionizes the validation of academic
certificates by utilizing blockchain technology. It
introduces a decentralized, tamper-proof ledger for
recording and verifying certificates, mitigating the
risks of certificate fraud. Each certificate is
assigned a unique digital identifier and stored on
the blockchain network, ensuring transparency and
immutability. The system employs smart contracts
to automate the validation process, enhancing
efficiency and accuracy. This eliminates the need
for intermediaries and reduces administrative
overhead. Real-time verification of credentials is
conducted by querying the blockchain ledger,
providing instant and reliable results. The system
supports the validation of historical certificates,
offering a comprehensive solution for institutions,
employers, and individuals. Overall, it establishes a
secure, transparent, and decentralized framework
for certificate validation, bolstering the integrity of
academic credentials. The main aim of this project
is to secure academic certificate and for accurate
management and to avoid forge certificate. To
achieve all this features, we are converting all
certificates into digital signatures and this digital
signatures will be stored in Blockchain server as
this Blockchain server support tamper proof data
storage and nobody can hack or alter its data. The
same data is stored in different blocks to perform
security feature. If by any chance if its data got
altered then verification gets failed at next block
storage and user may get intimation about data
altered.
