This paper presents the Pure/Epos approach to deal with the high complexity of adaptable operating systems and also to diminish the distance between application and operating system. A system designed according to the proposed methodology may be automatically tailored to satisfy an speciic application. In order to enable this, the application must be written referring to the innated interfaces ...

In order to ensure a secure data life cycle, it is necessary to delete sensitive data in a forensic secure way. Current state of the art in common database systems is not to provide secure deletion at all. There exist academic demonstrators that address some aspects of secure deletion. However, they are limited to their deletion approach. We argue, due to different data sensitivity levels (prob...

The quality of recommendations and usability of six online recommender systems (RS) was examined. Three book RS (Amazon.com, RatingZone & Sleeper) and three movie RS (Amazon.com, MovieCritic, Reel.com) were evaluated. Quality of recommendations was explored by comparing recommendations made by RS to recommendations made by the user’s friends. Results showed that the user’s friends consistently ...

This article examines the potential of application profiles and domain profiles as means to adapt technical specifications of data structures to particular needs. The authors argue that application profiling is better suited to increase the use of formal specifications than the creation of new specifications. The authors also describe a method to generate specific conformance test systems for m...

This paper presents the Pure/Epos approach to deal with the high complexity of adaptable operating systems and also to diminish the distance between application and operating system. A system designed according to the proposed methodology may be automatically tailored to satisfy an specific application. In order to enable this, the application must be written referring to the inflated interface...

In the last few decades, technological progress has been made important information systems that require high security, Use safe and efficient methods for protecting their privacy. It is a major challenge to Protecting vital data and the ability to threaten attackers. And this has made it important and necessary to be sensitive to the authentication and identify of individuals in confidential n...
