Zerolocated

Zerolocated is a term used in discussions of privacy-preserving geolocation to describe systems and practices that minimize or eliminate the disclosure of precise user location. It is not a standardized technical specification, but rather a broad category of approaches intended to reduce location exposure while preserving usable service functionality.

In practice, zerolocated methods encompass techniques such as on-device processing to avoid transmitting exact coordinates, geo-indistinguishability or differential privacy to add uncertainty to location data, spatial cloaking to generalize coordinates to larger areas, and k-anonymity in location datasets. Some implementations rely on cryptographic methods or trusted execution environments to prevent leakage of location information during processing or transmission. The overarching goal is to enable location-enabled services without exposing exact positions.

Applications of zerolocated approaches appear across mobile applications, social platforms, and analytics that require some geographical context but cannot or should not reveal precise coordinates. These approaches pose trade-offs between privacy and accuracy, potentially affecting service quality, user experience, and regulatory compliance. Challenges include defending against inference attacks, ensuring transparent user consent, and aligning with data minimization and privacy-by-design principles.

The term is used variably and is not tied to a single protocol or standard. Related concepts include location privacy, geo-indistinguishability, differential privacy, synthetic location data, and location-based data minimization. For specific implementations, the details of the methodology and the intended privacy guarantees typically determine how zerolocated is applied.
