The Central Board of Secondary Education (CBSE) has forged a partnership with American technology giant Microsoft to prevent leaks of examination question papers. The year, the board came under severe criticism following the leak of class 10 mathematics paper and class 12 economics paper. In order to keep a check on such incidences, the board has collaborated with Microsoft which developed an encrypted security solution for digital question papers for the board within a period of three months. This year, the question paper leak had triggered nation-wide outrage among students and parents.
"We have developed for CBSE an innovative solution which makes question papers leak-proof until 30 minutes prior to the start of the examinations," Anil Bhansali, Managing Director, Microsoft India (R&D) and Corporate Vice President, Cloud and Enterprise, told IANS in a telephonic interaction. "But if the question papers get leaked after they are allowed to download (just half an hour before the start of the exam) due to some bad actors, the system allows easy traceability as question paper for each centre are watermarked," Mr. Bhansali said.
On the other hand Microsoft claims that currently the solution is having its pilot run, but it has passed the first test with flying colours. As part of the collaboration, CBSE and Microsoft have successfully executed in July the first ever pilot of the digital question paper generation and delivery process at 487 centres for compartment examinations for class 10.
How does the system work?
In the new process, the system allows the Controller of examination to track the entire process using a software solution built on Windows 10 and Office 365. In the new system, the overall process is encrypted and a two-factor authentication process is embedded. This will help the examiner to identify themselves before they can download the examination papers. They are allowed to download the papers (after authentication) only 30 minutes prior to start of the exams. "The system allows various authentification processes. For example, it can be OTP (one-time password) based or biometric based. It is up to the clients what two authentification process they want to choose," Mr. Bhansali added. "The authentification can even be Aadhaar-based," said the Microsoft executive.
The solution leverages features in Office 365 to encrypt and watermark the papers. The watermark has the individual center's code imprinted on it which allows for localisation and traceability in the eventuality of a paper leak. A CBSE administrator initiates the distribution of the examination papers, which results in the generation of emails to the respective centres with a link to OneDrive, a file-hosting service operated by Microsoft, where an exam paper, specific to the exam centre can be downloaded.
Apart from securing the system, this digitisation process is expected to save significant amount of time and cost for examination administrators due to online paper generation, automated delivery process and reduction in approval cycles.
"The system that we have developed for CBSE can be easily replicated for other boards or examination administrators. We will be happy to share it with other central or state authorities that conduct examinations for various purposes," Mr. Bhansali told IANS.
