| Resumen en español | This paper describes a mechanism for detection of changes in a data set to be protected or monitored. The mechanism is based on the creation of detectors derived from self character str ings from the data set. The data str ucture used for stor ing detectors is a tree array. Each tree in the array stores detectors for a sequence of r adjacent char acter s within a lchar acter string extr acted fr om the data set. Each node in a tr ee r epr esents a char acter in a detector. In the monitoring phase, changes in the data set are detected going acr oss nodes of the tree ar r ay. A character string being analyzed is compared with detectors in the tree array. A change is detected when no matching route from the |
