Security with Noisy Data (Extended Abstract of Invited Talk)

摘要

An overview was given of security applications where noisy data plays a substantial role. Secure Sketches and Fuzzy Extractors were discussed at tutorial level, and two simple Fuzzy Extractor constructions were shown. One of the latest developments was presented: quantum-readout PUFs. Biometrics and Physical Unclonable Functions. Noise plays an essential role in a number of security applications based on biometrics and Physical Unclonable Functions (PUFs). In biometric authentication, the best way to preserve user privacy would be to store a one-way hash of the biometric, just like the password hashes in a unix password file.
