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.

A method of controlling information exposure in a multiparty transaction includes an originating transaction participant cryptographically encoding all information for each of the transaction participants such that a unique data content and encryption are used for each of the messages destined to the other transaction participants. The cryptographically encoded messages are transmitted to the transaction participants such that each may decrypt their message and respond to a primary transaction participant with status concerning their portion of the transaction. After reception of affirmative status messages from the transaction participants, the primary transaction participant may transmit messages to the responding transaction participants to execute the multiparty transaction. The originating transaction participant may also be provided an indication that the multiparty transaction is executed.

A trusted data store is provided for use with a trusted element of a trusted operating system on a computing machine. In the trusted data store, a storage medium stores data in a pre-determined arrangement, where the data includes trusted data from the trusted element of the trusted operating system on the computing machine. An access controller writes data to and reads data from the storage medium, and a trust controller is interposed between the computing machine and the access controller. The trust controller allows only the trusted element to perform operations on the trusted data thereof on the storage medium.
