Abstract
Remotely located lottery terminals, for operation by purchasers of lottery tickets, are adapted to be coupled by telephone to each other and to a central host computer as for verification of tickets by storing backup lottery data. Individual terminals are self-sufficient to approve ticket sales, issue tickets, encrypt data, register data and verify winners. Tickets are sold by terminals on the basis of various payment forms, e.g. cash, credit cards and payslips. One aspect of security in the relationship between the host computer and the remote terminals is provided by monitoring for operating anomalies, as a disconnected terminal, format irregularities or identification failures. Detection of an anomaly prompts corrective action, e.g. commanding a fresh call, realigning data or calling numbers for identification confirmation, as by use of ANI calling number identification.
