Abstract: The present disclosure relates to an improved method for digital communication and, in particular, an improved method for digital communication in terms of improved authentication and traceability. More specifically, the present disclosure relates to a method of performing a transaction between a first device and a second device wherein the first device having an established trusted communication relation with a first trusted device and the second device having an established trusted communication relation with a second trusted device, the first and the second trusted device each having an established trusted communication relation with a fourth trusted device, the first and the second device being aware of a policy for the transaction specifying a role definition for the first and the second devices.

Abstract: Policies are used when performing a transaction between a first and a second device, the first device having an established trusted communication relation with a first trusted device and the second device having an established trusted communication relation with a second trusted device, and the first and the second trusted device each having an established trusted communication relation with a third trusted device. A policy defines a set of constructs for creating rules to control the boundaries of a transaction. The policy defines role definition stipulating what interacting identities must have been validated as for the transaction to occur. The policy also defines a set of digest method algorithms or data referral methods to be used in the transaction.

Abstract: A method of performing a transaction between a first device and a second device, the first device having an established trusted communication relation with a first trusted device and the second device having an established trusted communication relation with a second trusted device, the first and the second trusted device each having an established trusted communication relation with a fourth trusted device, comprises the steps of the first device sending, to the first trusted device, first input data, and the second device sending, to the second trusted device, second input data, the first trusted device confirming the originality of the first device and sending the first input data to the fourth trusted device, and the second trusted device confirming the originality of the second device and sending the second input data to the fourth trusted device, the fourth trusted device, upon receipt of the first and the second input data, sending to the first trusted device a first receipt message comprising the f
