A Time Stamped Virtual WORM System
نویسنده
چکیده
When backup operators have to handle giga bytes of information daily, they usually find the task hard enough to leave security aside. This paper consequently intends to focus on proving documents’ authenticity regarding both content and date. In the context of WORM technology, it proposes a media independent tamper evident system using original cryptographic hash function techniques and secure time stamping within a given accuracy. Finally, time stamping upgrade mechanisms are proposed to extend security guarantees over years.

Streamed or Detached Triple Integrity for a Time Stamped Secure Storage System
Organizations and companies with integrity concerns for their archivals are currently left with very few and unconvenient solutions. To cope with those needs, a Time Stamped Virtual WORM system has been proposed previously, but only its concepts and theory have been examined yet. Hence, this paper focuses on defining practical block formats to help implement this system in reality. But there ar...
متن کاملNovel Approach for the propagation and detection of active worm in a Virtual System
Active worms are one of the major security threats to the Internet. This is because of their ability to propagate in an automated fashion as they continuously compromise computers on the Internet. Camouflaging Worm (C-Worm in short) is one of the active worms. The C-Worm is different from traditional worms because they can camouflage (hide) itself from the detection schemes by manipulating thei...

Apart from regular wheel wear such as decreasing wheel diameters and reduced flange thicknesses and heights, wheel flats (WF) and oval wheels (or OOR, Out-Of-Roundness) are the most common wheelset problems for railway vehicles. Within the FP7 Research Project “Saferail”, APT has developed an innovative wheelset monitoring system so-called “Wheel flat and Out of Roundness Monitoring (WORM) syst...
متن کاملAn active camera system for acquiring multi-view video
A system is described for acquiring multi-view video of a person moving through the environment. A real-time tracking algorithm adjusts the pan, tilt, zoom and focus parameters of multiple active cameras to keep the moving person centered in each view. The output of the system is a set of synchronized, time-stamped video streams, showing the person simultaneously from several viewpoints.
