Methods and apparatus for providing proof of multiple entities being co-located at a specific time and location. An attestor transmits an attestation message via short range communication; the attestation message includes a time stamp, a location stamp, and a verifiable digital signature. An attestee that stores the attestation message can produce the attestation message at a later time to any interested party, as proof of co-location with the attestor at the specified time and location. In one exemplary embodiment, the methods and apparatus are substantially “open” for public implementation. Such public implementation enables attestors and attestees without prior affiliation, to provide attestation. Furthermore, the device-agnostic methods and apparatus can provide attestation capabilities even in previously deployed systems and devices.
An apparatus adapted to generate a digital attestation, the apparatus comprising:
A method for securely recording the co-location of a first device and a second device at a time and a location, comprising:
An apparatus configured to receive a digital attestation from a second arbitrary device, the apparatus comprising:
A computer readable apparatus comprising a storage medium, the medium containing at least one computer program which, when executed by a computerized device:
A method of doing business, comprising charging at least one of a shipper or recipient of goods consideration for a digital attestation, the digital attestation providing substantially unequivocal proof of delivery of the goods at a particular location and a particular time based at least in part on a digital cryptographic element.
