A new research paper introduces a method for detecting tampering in surveillance cameras by monitoring for lens occlusion and abrupt scene changes. The system compares luminance and gradient statistics against a clean reference, incorporating filters for structured light and brightness fluctuations. Tested on controlled sequences and public datasets, the method achieved high accuracy and a low false-alarm rate, demonstrating its potential as an auditable subsystem for sensor health monitoring.
