An identity authentication method authenticates valid purchases of restricted products or services such as alcoholic beverages from unattended vending machines. The authentication method is designed to comply with all 50 States' requirements, as the equipment includes a field-programmable age requirement verification mechanism. The process consists of two primary steps: 1) Registration, a one-time procedure where a Patron's age is verified, fingerprint enrolled and information entered into an electronic tag, as well as a central database (if applicable); and 2) Purchase, which occurs each time a product is purchased, where the Patron presents the electronic tag to a tag reader (located on the front of the vending machine), authenticates his / her Identification by placing the appropriate finger onto a fingerprint scanner (also located on the front of the vending machine), then proceeds to purchase the product via cash, credit card, or whatever other method is applicable to that particular location.

Complex, end-to-end network services are set up via the configuration method: each component has a finite number of configuration parameters each of which is set to definite values. End-to-end network service requirements can be on connectivity, security, performance and fault-tolerance. A number of subsidiary requirements are created that constrain, for example, the protocols to be used, and the logical structures and associated policies to be set up at different protocol layers. By performing different types of reasoning with these requirements, different configuration tasks are accomplished. These include configuration synthesis, configuration error diagnosis, configuration error fixing, reconfiguration as requirements or components are added and deleted, and requirement verification. A method of performing network configuration management by model finding formalizes and automates such reasoning using a logical system called Alloy. Given a first-order logic formula and a domain of interpretation, Alloy tries to find whether the formula is satisfiable in that domain, i.e., whether it has a model. Alloy is used to build a Requirement Solver that takes as input a set of network components and requirements upon their configurations and determines component configurations satisfying those requirements. This Requirement Solver is used in different ways to accomplish the above reasoning tasks.
