Today’s face of the day is the face captured by a technology called BriefCam which helped catch the Boston Marathon bombers.Thanks to this video search engine technology hours of footage can be condensed into minutes, enabling the good guys to catch the bad guys faster. People like Nicky Hager after a hard day pawing through other people’s hacked correspondence, will no doubt decry this technology as being controversial and ‘ shocking ‘ because it is taking away people’s privacy. I say, if you are in a public place expect to be under surveillance for both your protection and the protection of others. The crime solving capacity of this technology is exciting.

Films like ?Minority Report? are no longer considered futuristic: video surveillance methods portrayed in this 2003 film are already in use. In fact, such methods have already helped in catching criminals and terrorists, albeit being controversial.

One of the most innovative technologies in this field was developed by Israeli company BriefCam, which helped in catching the Boston Marathon bombers. Using tracking algorithms, BriefCam enables users to track events caught on tape much more quickly, thus maximizing the potential of video surveillance.

Minority Report exists

From the development of earthquake after-shock software has come new software that can predict high crime areas:

Large earthquakes are unpredictable, but the aftershocks that follow are not and their occurrence can be predicted with mathematical models. It occurred to?Dr. George Mohler, one of the Santa Clara mathematicians, that criminal activity might not be random and that, similar to aftershocks, some crimes might be predicted by other crimes that precede them. The reasoning is based on the assumption that crimes are clustered ? it?s what police call ?hotspots.? Burglaries will occur in the same area and at the same houses because the vulnerabilities of that area will be known to the burglars. Gang violence is also clustered. A gang shooting will often trigger retaliatory shootings.

Using the aftershocks-inspired algorithms Dr. Mohler and his team?came up with a model, then sought to test it. In collaboration with the LAPD they plugged in data on 2,803 residential burglaries occurring within a block of the San Fernando valley 11 miles by 11 miles throughout 2004. For a given day the software calculated the top 5 percent of city blocks most likely to be burglarized. The results convinced the LAPD that, had they been using the program, they could have prevented a quarter of burglaries across the entire test region for that day.

The current, real world test of the software involves generating a map of the city areas most likely to be burglarized, the time of day they are most likely to get hit, and deploying personnel accordingly. The software is recalibrated every day when burglaries from the previous day are added to the dataset. They don?t actually expect to catch people in the act, but to deter more crimes with more effective patrolling. The test that is underway will be evaluated at six months, but already the data is encouraging. Zach Friend, crime analyst for Santa Cruz police,?confirmed to the New York Times that the program led to five arrests in July. Even more impressive, compared to July 2010 burglaries, the number of July 2011 burglaries are down 27 percent. Whether or not that trend holds remains to be seen, but so far it appears that being in the wrong place at the right time works.

Hmmm…will the NZ Police look at setting up a pre-cog department?
