1. Author- access control model Authorizations in the Author- model have the following format: < users, protection-objs, priv, prop-opt, sign > Component users denotes a (set of) user(s) to which the authorization applies. Component protection-objs denotes the (portions of) documents/DTDs (called protection objects) to which the authorization applies. The priv component denotes the access modes that can be exercised on the protection objects specified in the authorization.

An important feature of this protocol is that it tries to avoid disputes between the transacting parties. If disputes still arise, the protocol can handle these automatically, without manual intervention and within the protocol itself. The protocol allows the customer to be confident that he is paying for the correct product before actually paying for it. The protocol also ensures that the customer does not get the product unless he pays for it and that the merchant does not get paid unless he delivers the product.

If they do, the trusted third party next validates the payment token with the customer’s financial institution by presenting the token as well as the agreed upon sale price, Agreed_Price (from the purchase-order).
