Outer Bounds on the CEO Problem with Privacy Constraints
Vamoua Yachongka, Hideki Yagi, Hideki Ochiai
We investigate the rate-distortion-leakage region of the Chief Executive Officer (CEO) problem, considering the presence of a passive eavesdropper and privacy constraints. We start…
Secret-Key Agreement Using Physical Identifiers for Degraded and Less Noisy Authentication Channels
Vamoua Yachongka, Hideki Yagi, Hideki Ochiai
Secret-key agreement based on biometric or physical identifiers is a promising security protocol for authenticating users or devices with small chips due to its lightweight securit…
Biometric Identification Systems With Both Chosen and Generated Secret Keys by Allowing Correlation
Vamoua Yachongka, Hideki Yagi
We propose a biometric identification system where the chosen- and generated-secret keys are used simultaneously, and investigate its fundamental limits from information-theoretic…
Secret Key-based Authentication With Passive Eavesdropper for Scalar Gaussian Sources
Vamoua Yachongka, Hideki Yagi, Yasutada Oohama
We analyze the fundamental trade-off of secret key-based authentication systems in the presence of an eavesdropper for correlated Gaussian sources. A complete characterization of t…
Unified Expression of Utility-Privacy Trade-off in Privacy-Constrained Source Coding
Naruki Shinohara, Hideki Yagi
Privacy-constrained source coding problems have become increasingly important recently, and the utility-privacy trade-off has been investigated for various systems. As pioneering w…
Biometric Identification Systems With Noisy Enrollment for Gaussian Source
Vamoua Yachongka, Hideki Yagi, Yasutada Oohama
In the present paper, we investigate the fundamental trade-off of identification, secrecy, storage, and privacy-leakage rates in biometric identification systems for hidden or remo…
