Trusted watchdog method and apparatus for securing program execution

Abstract

An electronic controller for conducting trusted lightweight e-commerce transactions. A trusted transactional cache and the associated transactional protocol allow e-commerce transactions to be committed to a remote server extremely quickly and with little network overhead. The end-to-end transactions are completed is just a few seconds or less. The invention operates equally well on robust private networks as on unpredictable Internet or wireless networks. The transaction is automatically completed following a temporary communication failure with the central site or following a temporary local controller failure. The invention can advantageously be used in embedded Internet products such as fixed or mobile Internet kiosks, transactional terminals, and Internet Appliances.

Problems solved by technology

Moreover, existing e-commerce methods can leave the consumer wondering whether the online transaction was successfully completed.

At times, the consumer may not be certain that the online transaction was successfully completed until the goods actually show up at the door.

Removing the issue of bad or non-payment, such a transactional model for executing an online transaction is essentially biased in favor of the provider, in that the provider always knows whether the purchase request is valid or is invalid.

In contrast, the shopper may have doubts as to the success of his or her purchase request until such time as an explicit acknowledgment is provided, which may not occur until a quite a significant time after the online order has been submitted.

This is because e-commerce servers are not optimized to provide an instantaneous acknowledgment, especially when a clearing bank is involved in validating a credit card purchase.

Consequently, because of the lack of a reliable, speedy and trusted e-commerce transactional model, consumer-oriented Internet appliances optimized to carry out e-commerce are quasi-inexistent.
