The Encryption of Electronic Professional Certificate by Using Digital Signature and QR Code

QR code certificate verification

Nowadays, it’s extremely difficult to judge the legitimacy of an e-Signature on a certificate. They can be easily hacked into by third parties, forged, and duplicated. But QR code certificate verification does away with these problems while making it easier to sign, store, and share professional certificates.

Wondering how? Keep reading to find out.

How Can Blockchain Encrypted QR Code be Used to Solve Digital Signature Problems?

Digital signatures on professional certificates—issued by educational institutions, government agencies, training organizations, or enterprises—can be easily copied and replicated by bad actors.

This makes it difficult to trust the authenticity of a certificate and checking them one-by-one manually is not only time-consuming but also expensive, deterring organizations from verifying their legitimacy.

But blockchain encrypted QR codes can make it extremely simple for organizations to encrypt electronic professional certificates by using digital signatures and QR codes.

You might be wondering if the process is complex. Let’s find out.

Well, in the case of blockchain digital signature, a professional certificate’s issuer receives a cryptographic hash function (basically, numerical codes). These are generated to secure the blocks linked together, forming a part of the chain.

Now, the issuer’s private key encrypts the professional certificate to protect it from being intercepted by bad actors during the sharing stage.  A corresponding public key is also issued and shared with the receiver to decrypt the document.

Moreover, the unique hash code gets produced and is submitted to the algorithm. However, if the private key encrypts the document, then what is the function of the hash code? Why is it needed to safeguard the certificate?

Though the private key is vital for accessing the encrypted document, the receiver of the document is sent the hash code to compare their hash code with the original one. This lets the receiver know if the document has been tampered with or not during transit.

Even if someone manages to grab hold of the blockchain encrypted document and alters it, its hash code will change, notifying the issuer and the receiver of the tampering.

Sounds a little complex and technical, right? Additionally, where does QR code fit into all this and can anyone use blockchain and QR code to protect certificates?

Although the process sounds technical, this all takes place in the backend and you don’t have to personally take action or carry out the process described above. What you do need to do is find a dependable blockchain and QR code platform, like ProofEasy, and upload your signed certificates for safekeeping.

Now, place the unique QR code anywhere on the certificate and voila! your certificate gets encrypted by blockchain. You can share this certificate directly through the ProofEasy platform or copy the link and share it via mail, social media platforms, or other means. The receiver will have to scan the QR code and enter the OTP sent to the receiver’s verified mail id to gain access to the certificate.

The presence of QR code adds an extra layer of security for the issuer and makes it easier for the receiver to decrypt the document received. So don’t waste time and try out ProofEasy for FREE today!
