Abstract

A measure of security is provided by determining authenticity of an object (e.g., credit card, cell phone, car keys, etc.) by letting the object predict at which nodes multiple specific data packets are going to be in a distributed network in the next time slot.

Claims

1. An object with a predictor to predict at least a part of a pre-determined itinerary of at least one data packet in a distributed data network.

2. The object of claim 1, comprising logic circuitry.

3. A method of determining authenticity of an object, the method comprising receiving from the object a prediction of at least a part of a pre-determined itinerary of at least one data packet in a distributed data network;

and verifying the prediction.

4. The method of claim 3, wherein the data packet comprises an instruction as to its next destination in the network.
