USING BLOCKCHAIN FOR VERIFYING AND ISSUING CERTIFICATES.


Here, we are giving insights on the benefits of using block-chain for document (certificate) sharing and why we should adopt this method for issuing and verifying certificates in the Nigerian Education industry.

At Study-Local, authenticity of documents during our information verification process is very important to us.

Our e-send document sender file sharing system is operated using the block-chain technology, which is currently the most secure way of data file sharing.

Block- chain, is a growing list of records, called blocks, which are linked using cryptography. It is an advanced distributed database system that maintains a continuous growing record blocks secured from tampering. Each block contains a timestamp and link to a previous block, in a Merkle Tree Structure. Block-chain stores data using a decentralized cloud. A decentralized cloud is the advanced and next level cloud where the data is encrypted and each user controls their own encryption key. This makes the block-chain concept a rock solid, unshakable and unbreakable solution to help eliminate document modification, thereby allowing a document to maintain its originality and authenticity.

Study-Local has devised a secure means of issuing and verifying certificates by following the block-chain principle which works from a non-repudiation perspective. This means that the sender cannot later deny that they did not generate the document.

Typically, how this works is that the certificate that is sent out (upon receipt from the concerned institution) to the client requesting for his/her certificate or to the organization requesting for certificate verification for their staff, will have an electronic seal. An electronic seal is a piece of data attached to an electronic document or other data (certificate – as the case may be) which ensures data origin an integrity. For this purpose, electronic seal must be linked to the data sealed with it in such a way that any subsequent change in the data detectable and in such a way that a fake seal cannot be created without access to the data (usually a private key) used through use of a qualified digital certificate that is involved in the creation of a digital seal. The unique private key used in the creation of the digital seal ensures non-repudiation as earlier explained (the entity that created the digital seal cannot later deny that it did not create the seal for that document). If the document is modified after its digital seal was created, the digital seal is not valid for the modified document.

So, this basically allows certificates to be encrypted and delivered through a secure and trusted document exchange network.

Some benefits of this document sharing system are:

  • ·        As earlier said, the entity that generated the document cannot later deny that it did not create the seal.
  • ·        The document cannot be forged or faked.
  • ·        Documents are delivered in an encrypted format and are located in only one place.

You stand to be a part of all these benefits by requesting for your certificates or certificate verification through Study-Local.
