Claim 26:
27. A computer-implemented method for exchange of verifiable digital information, using a fact certification module and a fact verification module, the fact certification module, and the fact verification module each comprising a processor, a computer network interface, and wherein the fact certification module and the fact verification module each have access to an associated permanent storage system,
wherein during a fact certification stage, the fact certification module performs the method comprising:
receiving a digital fact for certification at the fact certification module from a fact presenter via the computer network interface;
issuing a digital certification data structure corresponding to the digital fact received for certification, wherein validity of the digital fact received for certification is verifiable upon presentation of the digital certification data structure to the fact verification module;
archiving the digital certification data structure in the permanent storage system associated with the fact certification module; and

wherein, during a fact verification stage, the fact presenter communicates the digital certification data structure to a fact receiver via a computer network;
wherein the fact receiver receives the digital certification data structure from the fact presenter; and
wherein the fact verification module performs the method comprising:
receiving a verification request at the fact verification module from the fact receiver via the computer network interface, the request comprising the digital certification data structure received from the fact presenter;
accessing said archived digital certification data structure in the permanent storage system associated with the fact verification module;
using said archived digital certification data structure to computationally verify said digital certification data structure received from the fact presenter; and
returning to the fact receiver via the computer network interface a verification response to the received verification request, the response comprising any of:
a search result,
a digital certification data structure retrieved from the permanent storage system, and

a formatted response data structure;
wherein the fact certification module is embedded in a digital device comprising one or more sensors that are adapted to make measurements;
wherein the fact presenter comprises said digital device;
wherein said digital fact presented for certification comprises the measurement made by said digital device;
wherein communication between the fact presenter and the fact certification module is internal to the digital device.
