Privacy-Utility Trades in Crowdsourced Signal Map Obfuscation. (arXiv:2201.04782v1 [cs.CR])

Cellular providers and data aggregating companies crowdsource celluar signal
strength measurements from user devices to generate signal maps, which can be
used to improve network performance. Recognizing that this data collection may
be at odds with growing awareness of privacy concerns, we consider obfuscating
such data before the data leaves the mobile device. The goal is to increase
privacy such that it is difficult to recover sensitive features from the
obfuscated data (e.g. user ids and user whereabouts), while still …
