Abstract: A network has a plurality of user accounts and a network enabled analysis system, which can receive selected information from a first user. A pattern can be established based on the received information, and responsive thereto a comparable pattern can be sought. A data base of patterns can be provided to which the established pattern can be compared using pattern recognition techniques. In one aspect, a processed pattern can be generated. The processed pattern can be compared to patterns of selected information received from other users in the network. In response to finding a comparable pattern, feedback can be provided to the first user.

Abstract: A number of fault-tolerant methods for purchasing digital goods with a digital token over a network in which the token's value resides either with a customer or a merchant are disclosed. One version of the method comprises the steps of establishing a price with a merchant for a digital good. A merchant-signed invoice and the digital good in encrypted form are then sent from the merchant to the customer. The invoice is signed with the customer's signature to produce a countersigned invoice. The countersigned invoice, a token (which can be an anonymous token), and identifying information for the token are sent from the customer to the merchant. The countersigned invoice, the token, and the identifying information are sent from the merchant for verification. The token is verified with the identifying information and the other information in the countersigned purchase order is checked.
