Biometric Analysis and Facial Recognition Technology
The day whilst get admission to badges and PIN codes could be previous may be coming. Facial Recognition Technology is a warm topic in recent times. It is shooting up on line, in newspapers, and on TV. All you’ll want to bring with you may be your face. And whilst that day comes your face can also show to be your quality pal, or your worst enemy

Recently, Google and Samsung added Galaxy Nexus, built on the Android four.0 Ice cream Sandwich platform. One of the alternatives it gives is facial recognition. Upon setup, you hold the display up for your face so the smartphone can scan and shop your picture. That’s all it takes. Next time you take a look at your messages, simply check out it and if the real time experiment suits the stored picture, get entry to is authorised and the telephone unlocks, and you are geared up to go.

The FBI is making ready to inaugurate a nationwide facial recognition machine. Authorized employees of participating states can be capable of upload a picture of a suspect into the bureau’s biometric identification machine. If there are feasible fits, a file of mug pictures ranked by way of similarity to the facial capabilities of the man or woman within the image will be sent to the inquiring organisation. Hopefully you’ll no longer be on both quit of this process.
The Privileged Few
Facial popularity verification techniques are already hooked up at business along with banks, retail shops and places of leisure where high rolling customers revel in VIP privileges. If you meet the membership necessities, your face is scanned into the device and on next visits a actual time scan need to suit up with the stored photo so as in order to revel in something privileges your fame entitles you to.
Keep the Line Moving
The practices so far discussed are designed for one-at-a-time identification exams but what about time critical locations in which scanning faces separately would bring about big bottlenecks and loud outcries? In the hobby of rushing up the technique without comprising ultra-modern security requirements, crowd-based solutions were advanced that barely sluggish the tempo of foot traffic. These make use of biometric analysis of facial features.
In order for most fulfilling facial analysis certain standards observe:
– Video Cameras have to be established at eye degree of a person of average top.
– The face need to be captured in as close a frontal role as feasible with a pan or tilt of no extra than +/-15.
– It is vital that the eyes be seen.
– Only minor parts of the face can be blanketed.
The video streams to a tracking station where it’s far analyzed for face visibility, function, and rotation angle, depending heavily on eye role. Next the face is cropped from the body, scaled, and rotated to a length of 128×128 pixels. The extracted face is then time stamped and given a camera identifier earlier than being sent directly to be compared to a information base of similarly configured snap shots of folks on targeted watch lists of terrorists, kidnappers, and fugitives. If a fit is made, an alert is issued and despatched to manned alert monitors devoted to receiving and showing just such indicators, permitting safety officers to consciousness at the diagnosed individual.
Video content analysis like any analytic method is developed and tested in controlled cooperative parameters. Unfortunately video surveillance is neither controlled nor cooperative. Due to the nature of surveillance, the majority of human beings passing thru don’t have any idea they’re beneath this type of scrutiny and so a positive share will not be optimally positioned. In addition environmental troubles can arise which include
– Cameras hooked up improperly, e.G. On a ceiling mount, will supply a bad pose perspective
– Bad illumination will result in indistinguishable texture records inside the facial area
– Thick lenses or sun shades hinder right face reputation
– An unstructured region offers suspects an possibility to hide.
Some of these problems may be removed, the most effective and most direct being digital camera placement. Since a frontal picture gives the pleasant hazard of recognition cameras can be hooked up at the end of an extended hallway technique or at the lowest of an escalator. A clever trick is probably mounting a digital camera near an information screen which include the arrivals/departures postings in an airport. But if someone wants to take an indirect route at the back of pillars or crowds, conceal at the back of darkish or reflecting glasses, or cover his face along with his fingers there are not any corrective measures, and the he maximum possibly might be able to thwart the gadget.
Likewise not all illumination troubles are surmountable. Indoor lighting fixtures can be minimized by means of adjusting the artificial lighting fixtures or the usage of dim outs. Outdoor use, however wherein the mild modifications because the day progresses, gives greater of a project.
The apparent application for biometric analysis is anti-terrorism. TSA agents at airports and border crossings would use it to compare the cropped pix against a terrorist watch list. But different industries are looking into it as properly. Might no longer casinos seize traffic upon entering and flow the video for evaluation and comparison to a facts base of acknowledged card counters? Similarly, shopping malls ought to do the same, checking site visitors’ photographs to convicted shoplifter databases.
So, is biometric analysis a alternative for skilled officers manning video consoles? Absolutely now not. The software relieves security officers of the tedium and attention lapses added on by way of viewing simultaneously streaming screens of video all day, but its pinpoint precision may be compromised or circumvented. However someday facial reputation generation, along with an IP digital camera device will function a treasured 2nd set of eyes for skilled safety personnel
