System and method for assigning quality to cryptographic identities used in a digital transaction

摘要

A method of assessing risk in an electronic transaction involves assignment of quality attributes to cryptographic identities presented in a digital transaction. The quality assignment supports assessment of risk in the transaction. The evaluation of risk in the transaction is made by assessing machine readable attributes of the digital identities along with transaction details. The digital identity attributes may be constructed using extensions of existing standards. A guarantee against risk of loss may be obtained by procuring insurance on the transaction before execution. Third party insurers may analyze the risk of loss in a transaction by assessing the attributes of digital identities along with transaction details and may provide a requestor with an insurance premium quote. Based on the value of the quote, the transaction participants may decide whether or not to execute the transaction.

1. A method comprising:
evaluating a quality attribute of machine-readable digital certificate to assess a quality of the digital certificate, the quality attribute comprising the identity of at least one item that was provided to a certifying authority in order to obtain the digital certificate; and evaluating a second attribute indicating an intended use of the digital certificate to determine a risk associated with the digital certificate, the second attribute indicating the intended use of the digital certificate comprising an indication of an amount of time the digital certificate will be used.
