The Secure CEO Problem With Physical Identifiers Under Logarithmic Loss and Quadratic Distortion Measures. (arXiv:2301.12526v2 [cs.IT] UPDATED)
cs.CR updates on arXiv.org arxiv.org
In this paper, we investigate the fundamental limits of the chief executive
officer (CEO) problem in which physical identifiers are treated as information
sources. To make the information leakage of the identifiers to the eavesdropper
via helper data negligible, private keys, uniformly and independently chosen,
are bonded to measurements of the identifiers at the encoders to generate the
helper data. The CEO problem is renowned for the difficulty in characterizing
the tight rate-distortion region, which is still an open question …
