Assignee: DE-IDENTIFICATION LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A method for de-identification processing of image files whilst maintaining a level of similarity between an original and a modified image file, the method comprising:
receiving at least one image file;
determining, for the at least one image file, at least one face for de-identification processing;
applying at least one transformation on the at least one face to create at least one modified image file, thereby limiting identification by computerized algorithms; and
validating the at least one modified image file by:
receiving, from a computerized human vision predictor trained to recognize similarity between image files similarly to the perception of an actual human, a measure of human-perceptual similarity between the at least one modified image file and the corresponding received image file;
receiving a recognition score from an existing computerized face recognition algorithm configured to identify the at least one face in the at least one modified image file;
determining if the measure of human-perceptual similarity exceeds a visual similarity threshold and if the recognition score is below a de-identification threshold; and
iteratively updating the at least one applied transformation and applying such updated transformation to the received at least one image file if either the recognition score is not below the de-identification threshold or the measure of human-perceptual similarity does not exceed the visual similarity threshold, else outputting the modified image file.
