CBSE Board Exam Results Being Secured Using Blockchain Technology

In a bid to go completely paperless and keep board results secure and tamper-proof, the Central Board of Secondary Education (CBSE) has introduced blockchain technology. Speaking to ANI on Sunday, CBSE Director of Information and Technology Antriksh Johri said, "Blockchain implementation has been done by CBSE. Earlier we introduced Artificial intelligence (AI) and Machine learning (ML) for affiliation systems. Here, the data is linked and stored with cryptographic security so that it is immutable and traceable."


What is blockchain technology?

Blockchain technology is a digital technology which is used to conduct public, private and nonprofit transactions securely without having a trusted third party. It is a decentralized digital ledger of transactions which are stored across a global network of computers, called the Blockchain. In the context of CBSE, it works as a verifiable and permanent record of all transactions, thus offering reliability to all the transactions and proof that a student's score has been assessed by the right person. Johri added, "The idea is to digitise all the processes and introduce transparency in the process by making everything traceable. If the result gets used to decide something in career, then we want to make sure that it is honest and genuine.


How the CBSE Board Exam Results Are Secured Using Blockchain Technology

Here are some reports from the ground, while breaking this story: The study material is assessed and uploaded through a 'Knowledge Management and Distribution System' (KMS) within the CBSE network. The students take a digital print out of the same and carry a copy in their possession in addition to the original paper copy.

A discrepancy can occur as one system can have 100 percent evidence and the other system can have just 50 percent evidence, and the one with less evidence cannot accuse the other system. These problems can be resolved with the use of Blockchain," Johri added.


Better security

A solution which ensures 100 per cent digitization, 100 per cent transparency and traceability of the scores and the marks secured through it. To begin with, around 27 lakh Class 10 and 11 students have successfully completed their CBSE board exams. The results of students who will sit for Class 12 exams would be available in the first week of June, Johri said. Taking steps for block chain The CBSE has set up 25 blocks of data. "There is a three-tier security mechanism — data level security, application-level security and network-level security. And then there is a hybrid of each of the layers," he added. Johri also said that the results are encrypted before they are given out. "The main chain is only used for information exchange and is not visible to the public.



"The data is stored on a network, then validated, added to a blockchain that gets sent across nodes to the CBSE Central Processing Center. This is the last point that is actually managed and monitored, and if a wrong copy is transmitted, the data is encrypted and destroyed." He said that this would create a secure environment and protect the data from being copied and tampered with. Meanwhile, according to the latest information from the Central Board of Secondary Education, the overall pass percentage is 83.05 per cent as against last year's 82.02 per cent. While the boys have secured a pass percentage of 89.67 per cent, girls have registered a pass percentage of 89.27 per cent.
