Defending against Fake VIP in Scant-Transparency Information Systems with QoS Differentiation
PublicationIn client-server information systems with quality of service (QoS) differentiation, Client may deplete Server’s resources by demanding unduly high QoS level. Such QoS abuse has eluded systematic treatment; known defenses using Client authorization, payments, or service request inspection prior to QoS assignment, are heuristic and environment-specific. We offer a game-theoretic approach on the premise that a service request is occasionally...

Uprawnienie do uzyskania od administratora informacji o odbiorcach lub o kategoriach odbiorców a cele prawa dostępu do danych. Glosa do wyroku TS z dnia 12 stycznia 2023 r., C-154/21 (RW przeciwko Österreichische Post AG)
PublicationGiven the complexity of modern data processing, individuals often do not know to whom controllers provide the information collected about them. In the commented judgment, the Court ruled that the controller is bound by the data subjects’ request to access information about the identity of the specific recipients of their data and has limited ability to provide them with information about the categories of recipients. This interpretation...

Aspect-Oriented Management of Service Requests for Assurance of High Performance and Dependability
PublicationA new approach to service requests management in case of insufficient hardware resources is proposed. It is based on wide aspects of requests analysis and it assures reliable and fast access to priority services. Requests are analyzed for, among others, time of occurrence, category of user who made the request, type of service, current system load and hardware utilization. Deterministic but dynamic rules help to manage system load...
