Complex Events are Composed of Objects Defined by States

2008-07-15 06:17:30 by Tim Bass in The Complex Event Processing Blog
 
...objects. Caution is advised, because a complex event is more than just a simple composite or aggregation of other events For example, in my earlier post Modelling Situations for Event Processing , we illustrated modelling in CEP by looking at an example situation, airplane collision. This complex event is composed of many objects than are not...

Spying on Computer Monitors Off Reflective Objects

2008-05-20 10:44:31 by schneier in Schneier on Security
 
...objects that one commonly finds in close proximity to the screen and uses those reflections to recover the original screen content. Such objects include eyeglasses, tea pots, spoons, plastic bottles, and even the eye of the user. We have demonstrated that this attack can be successfully mounted to spy on even small fonts using inexpensive...

Modelling Shoplifting

2008-09-07 07:30:15 by Tim Bass in The Complex Event Processing Blog
 
...objects we must track In the most simple model, we have merchandise-objects. Stores normally (physically) trackmerchandise-objects only at the exit/entry points of the store using some electromagnetic proximity detection technology. In this model, the detection configuration is a combination of simple alerting with humans watchingthe store...

...objects, aircraft-objects,accurately with very high confidence. In addition to trackingaircraft-objects, there is a database of information about the aircraft (ideally), such as make, model, age, range, passengers and other properties about the aircraft-object. In addition, there is a state-model for each aircraft, for example the aircraft...

A Question of Integrity: To MD5 or Not to MD5

2008-06-25 19:50:57 by Craig Balding in Cloud Security
 
...objects we are retrieving are not checksumming to the correct values. we hash and store objects by checksum and rehash the objects when we retrieve to ensure there is no data corruption. all the objects were having issues with were uploaded at approximately the same time period a few days ago weve stored 10s of millions of objects in S3 and...

A Complex Event = Sum (Events) + Situational Knowledge

2008-08-16 09:11:34 by Tim Bass in The Complex Event Processing Blog
 
...objects. If you follow this (flawed) logic, then counting integers is complex event processing; because 1 plus 1 is 2, and 2 is an aggregation of 1 and 1, so 2 is a complex event (not Since we know that counting is not a complex processing operation, then some folks would say that you can process complex events with very simple operations...

Towards a Streaming SQL Standard

...objects. In almost all advanced CEP/EP applications is is necessary to perform robust track and trace operations on streaming event objects, like tracking the position of an airplane. Tracking the position of an aircraft can be modelled very nicely with event stream processing. Tracking individual event objects is a precuror to multiclass...

Maslow's heirarchy of security posture?

...objects look big and farther objects look small?" This made me think about blindness that is created by obviousness in our thinking process. "Pride" that we [adults] know more than kids put an end to our constant questioning of our surroundings. "Pride" is one among the 7 deadly sins of Website Vulnerability Disclosure according to Jeremiah....
