MUMBAI, India, Aug. 10 -- Intellectual Property India has published a patent application (202641089321 A) filed by Vellore Institute Of Technology on July 22, 2026, for “an Adaptive Privacy-Protection System For A Digital Display”.
Inventors include Jagadeesh; and Ms Shabreena.
The application for the patent was published on July 31, 2026, under issue no. 31/2026.
Abstract: The present invention relates to an adaptive privacy-protection system for digital displays configured to predict, detect and neutralize unauthorized visual access to sensitive information. The system comprises a multi-modal sensor network, an edge processing unit, a display-content analysis engine, a display-control unit, a graphics-rendering engine and a display-driver interface. Observer position, movement trajectory, posture, viewing direction and gaze behaviour are analysed to determine observer intent and forecast a future visual-exposure condition. Displayed content is classified according to sensitivity and represented as a dynamic privacy heat map. Based on observer intent, gaze correlation, content sensitivity and environmental risk, the system selectively modifies pixel emission, sub-pixel characteristics, opacity, refresh-cycle behaviour, temporal frame rendering or directional light output of sensitive display regions. The system further detects reflection- based viewing and image-capture devices and generates adversarial rendering patterns to degrade unauthorized photographs or recordings while preserving readability for an authorized user.
