TallyCalculus 2.0: Outsmarting Impersonators
- TallyCalculus is an assessment platform by TEPL designed for Tally certification and exam preparation, featuring tools like Question Bank Management and on-screen calculators.
- The platform includes proctoring tools to ensure exam integrity, monitoring candidates through webcam feeds, screen activity, and audio analysis.
- Challenges like false positives due to environmental noise led to the implementation of smart thresholds and machine learning models in TallyCalculus.
- Identity verification was improved with face comparison and liveliness detection to prevent impersonation risks during exams.
- A progressive face comparison approach was introduced, capturing fresh images at the start of exams to reduce false positives.
- Technologies like TensorFlow and OpenCV were utilized for face comparison and liveliness detection, optimizing the in-house proctoring service.
- Privacy concerns were addressed by keeping all exam data within the infrastructure, avoiding external processing in cloud-based solutions.
- TallyCalculus stands out for its cost efficiency, data privacy, and customization compared to cloud proctoring services.
- While the system excels in identity verification, there are ongoing improvements needed for low light conditions and liveliness detection.
- Overall, the new proctoring enhancements have made TallyCalculus more efficient and cost-effective while maintaining exam integrity.
