Abstract
A method can be implemented in a portable device operating in a wireless communication network. The method is for securely reporting an indication of a current geographic location of the portable device to a server without revealing the current geographic location of the portable device to the server, where the server is communicatively coupled to the communication network. The method includes generating a pseudo-random value using a signal from an environment in which the portable device operates, generating a location descriptor based on the current geographic location of the portable device, applying a cryptographic function to a combination of the pseudo-random value and the location descriptor to generate a secure location indicator for the portable device, and causing the secure location indicator to be electronically transmitted to the server via the communication network.
