The invention presents a method and system for recording a detailed record or "transcript" of the acts, events and forensic circumstances related to a party's affirmation of an electronic document, transaction or event. The transcript is recorded in a data object made secure through the use of encryption and a checksum. The system directs a ceremony whereby the party affirming the document, transaction or event is required to undertake a series of steps in order to successfully complete the affirmation and have the affirmation recorded; thus participation in the ceremony must take place before an affirmation will be accepted. The steps of the controlled procedure serve to gather evidence to confirm specifics such as that the affirming party: i) is in fact the identified party; ii) understands that by entering affirming data, e.g. a password, key, biometric sample or other affirming data he or she is thereby affirming or becoming legally accountable for the undertakings of the document, transaction or event triggered by computer interaction; iii) has adequately reviewed the document, transaction or statement to be affirmed (where a client application presents such a document transaction or statement to the system of the present invention); and iv) understands the undertaking of an event or the provisions within the document, transaction or statement and the consequences of affirming it. The system of the present invention is flexible and can be configured to accept all types of biometric, infometric and cryptographic signatures or affirming acts, such as those created by passwords, secret cryptographic keys, unique secret numbers, biometric recordings such as handwritten signatures or other biometric information, or multi-media recordings of affirming statements. It also permits the affirmation procedure to be tailored to the specifics of a client application through the use of an authentication policy component.
