- 摘要：
- A log file is generated from data supplied by cards readers that are part of an access control system and that read access control cards in connection with restricted areas. Probabilities of card holders entering the restricted areas are computed based on the data in the log file. Unusual access patterns are detected from the data in the log file based on the computed probabilities. Group associations between card holders are detected based on common movement of the card holders in connection with the restricted areas. A new log file is created based on those of the detected unusual access patterns that are not associated with the group associations.
