The application for the patent was published on August 28, 2026, under issue no. 35/2026.
Abstract: The present invention relates to a method (100) and a privacy-preserving facial stress detection system (200). The method (100) comprises obtaining a facial image (105), identifying a facial region and generating facial positional information (110), extracting a forehead region, a left eyebrow region, and a right eyebrow region (115), suppressing facial portions outside the extracted regions to generate privacy-preserved image data (120), generating region-specific feature vectors (125), generating stress prediction values (130), generating confidence values (135), generating a consolidated stress assessment score (140), and determining a stress condition of the subject (145). The system (200) comprises an image acquisition module (202), a face localization module (204), a region-of- interest extraction unit (206), a facial region suppression unit (208), a feature extraction module (210), a stress inference module (212), a confidence determination unit (214), a fusion unit (216), and an output module (218) configured to perform privacy- preserving stress assessment.
