Abstract: In an example, a client-server platform identity architecture is disclosed. The platform identity architecture may be used to enable a venue operator to provide online services and to collect telemetry data and metrics while giving end users greater control over privacy. When entering a compatible venue, the user's device generates a signed temporary pseudonymous identity (TPI) in secure hardware or software. Any telemetry uploaded to the venue server includes the signature so that the server can verify that the data are valid. The TPI may have a built-in expiry. The venue server may thus receive useful tracking data during the term of the TPI, while the user is assured that the data are not kept permanently or correlated to personally-identifying information.
