Location Privacy

Definition ∞ Location privacy concerns the ability of individuals or entities to control access to and disclosure of their physical geographical coordinates and movement patterns. It protects against unauthorized surveillance and the aggregation of personal location data. This concept involves safeguarding information that could reveal sensitive details about routines, associations, and activities. Technologies such as obfuscation, anonymization, and decentralized identity solutions aim to bolster location privacy.
Context ∞ In the realm of digital assets, location privacy gains relevance with the increasing use of blockchain for supply chain tracking, geo-located NFTs, and decentralized physical infrastructure networks. Debates arise regarding the balance between transparency for verification and the need to protect individual or business location data. Zero-knowledge proofs offer a potential solution for verifying location without revealing precise coordinates. Future developments will likely focus on integrating advanced cryptographic techniques to secure location data within decentralized applications.
