Reconstruction of Patch Face Reducing Malicious Attack in Secure Computation
|Related article at Pubmed, Scholar Google|
Secure Computation of Face Identification (SCiFI) is a recently developed system which combines security with face recognition system and that ensures the list of faces it can identify remains private. A detailed study that shows the outcome of distorted input attacks on the system—from both a security and computer vision standpoint is given. In particular, the following is proposed, 1) a cryptographic attack that allows a fraudulent user to unnoticeably obtain a coded representation of faces on the list, and 2) a visualization approach that turns the lossy recovered codes into human-identifiable face sketches exploiting the breach.
