As India faces a rise in cybercrime, deepfake threats and digital fraud, an award-winning Assam school teacher has emerged as an unlikely but formidable innovator in artificial intelligence-powered cybersecurity solutions.
Prasenjit Sarma, a teacher from Barpeta district and recipient of the prestigious Global Teacher Award 2025, has developed three advanced AI-based mobile applications designed to enhance digital safety, counter cyber threats and protect users from online fraud. His work seamlessly bridges education, technology and public interest, putting Assam’s grassroots innovation on the national technology map.
Among his innovations, DeepGuard has received particular attention for its ability to accurately detect and verify deepfake content. Powered by artificial intelligence, the application distinguishes between real and AI-generated images and videos with high accuracy, addressing growing concerns about misinformation and manipulation of personal information. The app’s impact was recognized nationally by winning the Tech Avishkar Award at the eRaksha competition.
The second application, VirusGuard, is a comprehensive cybersecurity solution designed to identify digital threats across platforms. This app scans files, internet links, images, and applications for malicious APKs, viruses, and other cyber threats. By integrating intelligence from over 100 globally recognized antivirus engines, VirusGuard provides real-time threat detection to instantly protect your smartphone or computer as soon as a risk is identified.
Rounding out the trio is FraudGuard, a real-time fraud detection tool focused on voice-based fraud. During live calls, the app uses AI to transcribe conversations and instantly analyze them for suspicious patterns commonly associated with phishing, financial fraud, and identity theft. FraudGuard sends alerts as soon as it detects potential threats, allowing users to take immediate preventive action.
Beyond cybersecurity, Sarma has also developed several AI-powered tools aimed at transforming classroom instruction and leveraging technology to support agriculture, underscoring his broader vision of leveraging artificial intelligence for social good.
From the classrooms of Barpeta to the forefront of India’s digital safety ecosystem, Prasenjit Sarma’s innovations prove how educators can play a vital role in shaping the country’s technology future.
