A public key infrastructure comprising a participant that issues digital certificates. Each digital certificate can be relied upon in at least two different trust domains. The public key infrastructure does not employ policy mapping between or among the trust domains. Furthermore, the public key infrastructure does not link any pair of trust domains via cross-certificates. Just one trust domain is bound to the digital certificate at any given moment. The current trust domain that is to be bound to the digital certificate is elected by a relying party at the time of reliance, based upon a specific certificate validation methodology selected by the relying party.

Binding a digital certificate to multiple trust domains

A system and method are disclosed for transparently providing certificate validation and other services without requiring a separate service request by either a relying customer or subscribing customer. In a preferred embodiment, after the subscribing customer digitally signs a document (e.g., a commercial document such as a purchase order), it forwards the document to a trusted messaging entity which validates the certificates of both the subscribing customer and relying customer and the respective system participants of which they are customers. If the certificates are valid, the trusted messaging entity appends a validation message to the digitally-signed document and forwards the document to the relying customer. A validation message is also preferably appended to a digitally-signed receipt from the relying customer and transmitted to the subscribing customer. In this way, both the relying customer and subscribing customer obtain certification of their respective counterparty to the transaction.

Electronic Tags are mounted on swimmers to reduce their risk of drowning by identifying when their heads are underwater for periods of time which may indicate a dangerous submersion situation, and for triggering corresponding alerts and alarms. In this method, each monitored person is equipped with a lightweight electronic Tag worn on the body that communicates with monitors that issue the alerts and alarms, including audible and visible distress signals. The monitors, in turn, communicate the alarms to receivers used by supervisory personnel, such as lifeguards or parents. The invention may be used in aquatic environments, such as public recreation facilities, pools, waterfronts, and water parks, as well as in more private settings, such as homes, apartment buildings or hotels.

A system and method for providing warranties that financially guarantee one or more facts associated with an electronic transaction. In a preferred embodiment, warranties issued to the present system comprise a contract between a first party and a second party in which the first party: (1) warrants one or more warranted facts (2) for damages up to a warranted amount (3) if claimed by a relying customer within a claim period. The warranty is preferably issued by a participant in response to a request received from a customer that specifies a desired warranted amount and claim period. The participant and root entity evaluate the request in light of a plurality of factors and determine whether or not the warranty should be issued. In a preferred embodiment, the warranty comprises a contract between the buyer and its issuing participant. The seller is preferably a third-party beneficiary of this contract.
