Biometric templates can be inverted for attacks, but also protected with hashing

A pair of papers from the Idiap Research Institute’s Biometrics Security and Privacy Group show the potential vulnerability of biometric templates to 3D reconstruction attacks, and a possible way to protect those templates through hashing.

Both papers were shared over LinkedIn by Idiap Senior Researcher Sébastien Marcel, who also co-authored each.

A new method of cancelable biometric template protection was presented in “MLP-Hash: Protecting Face Templates via Hashing of Randomized Multi-Layer Perceptron” at the EUSIPCO 2023. The research’s …
