Patent ID: 8719929

Claim:
A method for recognizing attacks on a self-service machine that has a series of components, comprising the steps: Identifying all sources of information in the self-service machine and weighting the sources of information with a two-dimensional input variable that includes a variable degree of confidence value corresponding to a degree of confidence that a statement from the corresponding source is accurate and a plausibility of an event value selected from a range of probabilities with a lower bound and an upper bound; Modeling the self-service machine with a system of rules that includes states and events of the components, based on the identified sources of information and the weighting; Monitoring the states and events of the components by a monitoring unit; Applying the system of rules stored on a memory system to the states and events through a processing unit that loads the system of rules from the memory system and receives the information from the monitoring unit; Checking whether the system of rules has determined an attack through the processing unit by applying the system of rules and the states and events to each other in order to report said attack to a message system.
