Biometrics Gaining Ground in Law Enforcement

Even though biometric recognition systems are "inherently fallible", that shouldn't be a reason to deny the PoPo their new toys. Surely, all good citizens won't mind being scanned, even if a "false positive" results in their temporary incarceration...

Biometric facial recognition isn’t as unique as a fingerprint, but it will reduce the number of possible matches in the data pool to something manageable

All of us accumulate a lot of keys over time. We have locker keys, door keys, desk drawer keys, car keys, padlock keys, and keys that just appeared one day with no apparent use or function. If you have keys, you’ve probably lost keys, too. What if you had a key that was impossible to lose? That’s biometrics.

We’ve been using biometrics for over a hundred years to identify people. Fingerprints are the measurement that first comes to mind, but people are included or excluded from a sample of interest by more evident characteristics such as gender, hair and eye color, height and weight, and age. Some of these things can be changed at will, and other change over time all by themselves, but many key measurements remain constant.

A face changes with age, weight gain and loss, and when disguises or facial hair is added or removed. What doesn’t change are the distances between facial landmarks such as pupils, corners of the mouth, tip of the nose, and the polygons formed by drawing lines between these landmarks. Biometric facial recognition isn’t as unique as a fingerprint, but it will reduce the number of possible matches in the data pool to something manageable...

TERMINOLOGY

fuNctioN cReeP: is what occurs when an item, process, or procedure designed for a specific purpose ends up serving another purpose for which it was never planned to perform.

Big Brother: an entity that is able to watch over all our actions in a unknown restrictive, controlling way with covert technology or other clandestine activities. It is commonly used to refer to a fear of the day when we will have zero privacy, due to government surveillance and personal accurate knowledge. The term was born from George Orwell's book "1984" where a government controls its citizens through continual surveillance.

The 4th Amendment: "The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."

Panopticon: first used by Jeremy Bentham as an architectual model in designing a prison. The concept follows that you could save money by building a circular prison with a singular tower in the middle for the guard. By keeping the guard in the dark and all the prisoners in the light, those being guarded could not tell when they were being watched.

Surveillance: In the middle ages, Surveillance was a man on a horse who was called a "scout." Now surveillance includes satellite imagery and aerial photography, sometimes from unmanned aircraft, and computer network hacking. Some more common, everyday surveillance techniques include eavesdropping, dumpster diving, video monitoring, and RFID.

Biometrics: automated methods of recognizing a person based on a physiological or behavioral characteristic. Among the features measured are; face, fingerprints, hand geometry, handwriting, iris, retinal, vein, and voice. Biometric technologies are becoming the foundation of an extensive array of highly secure identification and personal verification solutions.

Iris Scanning is a method of biometric identification; pattern recognition is used to determine the identity of the subject. Iris scans create high-resolution images of the irides of the eye; IR illumination is used to reduce specular reflection from the cornea. The iris itself is a "good subject" for biometric identification, because it is an internal organ that is well protected, it is mostly flat and it has a fine texture that is unique even for identical twins.

RFID stands for Radio Frequency IDentification, a technology that uses tiny computer chips smaller than a grain of sand to track items at a distance. RFID "spy chips" have been hidden in the packaging of Gillette razor products and in other products you might buy at a local Wal-Mart, Target, or Tesco - and they are already being used to spy on people.

The VeriChip passive RFID device is the core of key VeriChip applications. About the size of a grain of rice, each VeriChip contains a unique verification number, which can be used to access a Subscriber-supplied database providing specific information. Once implanted just under the skin, via a quick, painless outpatient procedure (much like getting a shot), the VeriChip can be scanned when necessary with a proprietary VeriChip scanner. A small amount of radio frequency energy passes from the scanner energizing the dormant VeriChip, which then emits a radio frequency signal transmitting the individuals unique verification (VeriChipID) number.
