Abstract: A database server is communicatively coupled to a database storing multiple data records which are accessible by a number of data access systems communicatively coupled to the database server in order to claim exclusive access to a data record for a specifiable time period by one of the data access systems. The database server stores associations of the data records with the data access systems defining which data access system is generally allowed to access to which data record and an exclusive access times inventory defining which of the data access systems with allowed access has already been granted exclusive access to which data record for which time periods.

Abstract: Systems and methods for monitoring user authenticity according to user activities on an application server. A user-modeling process and a user-verification process are performed. In the user-modeling process, a user model is adapted session-by-session to user activities in which the user model includes a plurality of adaptive feature-specific user-behavior models. The user-verification process includes determining a plurality of feature-specific risk-score values, comparing the at least one of the adaptive feature-specific user-behavior models with a respective feature extracted from user activity in the user session on the application server, and determining a total risk-score value indicative of user authenticity by weighting and combining the plurality of feature-specific risk-score values. If the total risk-score value is greater than a given threshold, a corrective action is performed.
