About Electronic Biometric Access Control

Biometrics, or the recognition of the identity of a person based on a biological aspect of a person is actually a very old technology. We use every day When biometrics is used "computer" we call the human mind: for example, when we recognize someone looking at your face, or when a written signature verifies contrary to what we hope to be a bona fide copy of a signature. The futuristic biometric technology feeling arises when we compare the traditional biometric with the new capabilities we have in electronics. Now we can use electronic devices to make judgments about the authenticity of biometric person, ie "X is the person who claims to be?" Since the information and digital age is here, technology has happened that makes it exceptionally accurate authentication and, potentially, a much more reliable authentication of a person than traditional fingerprint ruling man.

Technology experts authentication usually classify the criteria used to verify someone's identity based on a few different categories. "What you know" or Wyk, is a form of authentication: a common version of this will occur if an electronic banking terminal PIN (personal identification number). "What you" or w and h, is another criterion, and this refers to the possession of an object, such as identification of an ID card or passport, but you might even consider a simple key to the door as a sort of w and h proof of identity to allow access on private property or controlled access. Biometrics according to this classification scheme, usually named "What you are" or WYA. It is the presentation of a physical you that is enough unique and individual, in order to obtain authentication.

Electronic access control (EAC) on the properties based on biometrics is not a new technology, since for decades and has taken many forms. Hollywood movies have long represented high-security facilities that finger use and handprints, eyes (iris and retina) scans, facial and voice recognition and so on, in order to verify identity. Of course, the media usually represents the technology as used by spies, corporate facilities high tech, ultra-wealthy elites and society: possibly protect invaluable assets and information, or to prevent espionage and treason. Only recently has become an exciting time for rest of us, technologically speaking, as "the digital age has brought biometrics-mail to a standard of quality and price that is within reach of the average consumer.

Scanning biometric fingerprint door locks

The most recent article is a consumer device access control biometric fingerprint scans of a person in order to allow access to a property, or even a vehicle. commentators of the high tech industry see biometrics as a new emerging technology that will eventually replace, or at least offered along with all other forms of access control (such as keys or electronic devices to control access based on PIN code keypads, swipe the magnetic or radio frequency identification (RFID) cards / key fobs). One of the main reasons for this is that the biometric device potentially offers an entry control solution is free of the typical problems that plague older technologies. That advantage may simply be avoiding that horrible feeling you get when you are standing at your door and can not find your keys, or when you have pins in his head that he can not remember the right to access a property. Maybe is when the so-called magnetic stripe card has lost its magnetic properties, or you have lost your card, or when a RFID key fob is out of batteries, stolen, or simply has not notified the lock. Biometrics can be an advantage for those with physical difficulties of managing some of these technologies old. With biometrics, all you need is a finger placed on a small screen that scans the fingerprint and then then get access to your property.

This is a relatively new technology for the consumer market, and so if you're planning to test a biometric access control device, it pays to be prudent in terms of the unit you select. What do you need to take into account? Knowing this could mean the difference between having a new and more friendly to your front door, or one that ends with a great frustration, because imitating Jack Nicholson in a double ax "Here's Johnny "scene in the movie" The Shining. "Therefore, the following are some points to consider when selecting a biometric device.

When to Use Biometric EAC

The wide range of benefits does not carry or use keys or other physical devices are not can describe in great detail here, and most people immediately think of a list of benefits for your home. Suffice it to say, the potential benefits can be many and varied. They can range from greater accessibility potential for disabled, elderly and young children through the profits made in our great Australian beach culture, where many will see it as an ideal to be able to go to the beach and not have to take along a set of keys (or other devices that could be lost or stolen). Some applications can achieve significant benefits of implementing a biometric access control, inventory control keys or other devices in an ever changing customer would be "a nightmare", or simply cost prohibitive. Examples include nurseries, schools, industrial complexes and corporate offices, and government high security and commercial operations. "The USA in Disneyland" (and also the location of Hong Kong) have implement a system to scan fingerprints called "Ticket Tag" to control all its visitors with the control system of the complex range of levels access depending on what type of visitors to purchase inputs. Hotels can also greatly benefit from the elimination of the need to maintain inventories of key or card, while the release of it's guests to take away or to check key at reception each time you enter / exit the building. Computer networks remotely can control some biometric locks and some locks are programmable to remove an authority customers to access a room automatically, after a specified time interval. Many biometric devices have built in audit trail "that can keep a record of entries by the user, date and hour. This can be useful to avoid the "friend bundying" in the workplace, or provide a form of surveillance on children for parents concerned. Applications and potential benefits of biometrics are only limited by imagination, and some benefits can make a big difference compared to technologies older.

Fortunately, in most applications, biometric technology is an adequate substitute for older technologies, and biometrics can offer a solution for versatile access control for residential, governmental and commercial / industrial situations. However, There are some exceptions. In one case a few years ago in a British prison invested in devices biometric fingerprint scanning to control access through internal components of the prison. Because the biometric device selected for the prison was inaccurate, the inmates were quick to exploit the weakness of the mechanism in particular, that simply did not have a good discrimination between different enough fingers to keep prisoners out. Consequently, they were able gain unauthorized access to internal areas. (The important issue of the accuracy of biometric devices will be discussed below.) While the total security of prisoners is not compromised for a short time the prison black market flourished. Some commentators rightly pointed out that this event was not a prison completely good place to have a biometric device, as some prisoners might not hesitate to cut the finger of a guard, if it meant free access to (or in some cases, an extra box of cigarettes). It is certainly the last place I want to install biometric access control, but not necessarily for security reasons, because biometric modules can sometimes discriminate between a connection and a cut finger, based on measurements such as body temperature reading. The main reason for not installing such devices in prison is simply that prisoners may misperceive that they could use to access the broken finger on his freedom, and, regardless of his success in escaping-the false perception alone could work much to the detriment of a prison officer of bad luck.

Physical attributes sometimes do not mix well with biometrics. A visitor to Disney had problems with readers because there lymphodema in her right arm, which was the one who chose to have their fingers scanned. When the arm swelled up during the course of the day, fingers spread and became different fingers in the eyes of the biometric scanner. A simple cure if the arm would have been used not swell, but it gives us an idea of a problem that could occur for some users. Rarely, people has little actual fingerprint that can confuse some biometric readers, resulting in the malfunction of the device for that user.

Precision Biometrics

When buying a biometric lock one must be careful to select one brand of device that has high levels of accuracy, or to put it another way, low levels of error. In biometrics, there are two typical measurements made in the field of biometric error: that of FRR or False Reject Ratio "and FAR or" false acceptance ratio. " The lower each ratio or rate, the better the biometric product.

FRR is also known as the rate of "insult", and this is quite an appropriate term. This is the number of times they are insulted its lock on the door, and who mistakenly but quietly beeps to inform you that you really are not you, but rather a pretender to the throne. FRR equals directly to the usability of the device. A registered user (ie someone whose fingerprint is carried out within the memory of the lock or locking the controls as a authorized operator) should be allowed to enter with ease. If a biometric device has a low FRR, then it should not require a series of attempts before you can enter your home or workplace. A high FRR rate or insult biometric device can be a frustrating life.

The second measure of accuracy, FAR, is critical. You have to do with the security provided by the device. How easy it is for a user's fingerprint, a real "pretender" to enter the device? How easy is a technology to imitate the lock fool to think that truth is the finger? A high rate of FAR or fraud may be a violation security waiting to happen.

Lies, Damn Lies and Statistics

With buying a biometric lock, look carefully at the FAR and FRR rates. Should be as low as much as possible. However, it also worth considering how specifications are collected. Some biometric locks use what might be called a security environment "in order to compromise between the fingerprint discrimination and authorized users the ease of entry, that is, a configuration that allows you to trade off performance between insults and false is false or permission granted to persons unauthorized. In my view an entirely bad thing to have a biometric device, because the user should not have to be forced to modify key settings: everything must be purely automatic. Performance of a biometric lock should be about achieving both accuracy levels, while because that is what is required in the real world. The manufacturers who build a level of adjustment on your device are possibly trying to achieve better performance numbers than your product that can deliver in practice.

Nor is it worth to be too serious about the performance specifications that are offered by manufacturers. While it may serve as a useful guide, the specification that states, for example, a "false rejection 1:10000 relationship" could never reach the maximum performance in practice. These performance figures are based on a combination of empirical data and mathematical analysis. The best thing to do is test the model your fingerprint, finger placement entered in the device and access a number of times and see how repeatable. If fingers are scanned repeatedly allowed until you get tired of the operation control input, then it is likely that the blockade is going to be easy to live with. If you find a lock that only beeps a denial input, and requires time to look back one hundred, it would be safe to say that this is going to be a good lock for use on a daily basis. Rare physical attributes (such as noted above) can sometimes confuse some biometric readers. So the first test and make sure the product is specifically appropriate finger.

Another indicator of reliability can be checked with the supplier as to who does the form of biometric data in the biometric device. Are they a reliable and recognized source of high-tech hardware?

Ease of use biometric

Figure 1: A biometric device with a friendly, easy to use menu driven interface main navigation button, the industry standard and a large screen. Figure SEQ ARABIC * A complete, standard numeric keypad on the front of an assistive device with ease of operation.

Not much use having a biometric device if you need the proverbial Ph.D. in order to use it. Some locks are so difficult to use that even a video of the steps required to operate the device (let alone program it) is somewhat confusing. Of course, the ease with which you can use a biometric device helps or hurts a lot in terms of how happy he is with your purchase. Look for a large and easy to see the screen, with roles control to navigate an intuitive menu. If the biometric device is configured as, for example – mobile phones or cameras easy to use digital keyboards with features such as four-way navigation, then it is probably easier to use. Try to make sure that if you want to reach a function, it requires both a user manual and a penchant for astrophysics: rather, it only has the ability to read a simple menu and press the navigation keys, buttons.

Do not neglect the interface to operate outside, when it comes to choosing a good biometric device. If the unit has an industry-standard keypad lock body outside, this is indicative of input control easy when you choose to use a number Pin in place of, or in addition, a fingerprint scan. A full keyboard in front of the device is also an indication that the numbers entering the biometric device (for programming the basic operations) will be somewhat easier than it is only a few buttons and do not adequately represent the full range of numeric digits (0-9).

Biometrics and Privacy

There has been some justifiable concern raised by privacy advocates and the press in general on privacy issues related with biometrics use. Look for biometric units that capture and process only the image of the fingerprint, but rather use "minutiae points" which are very specific details taken from a fingerprint. A biometric device works with the minutiae points immediately capture certain aspects of the finger and fingerprint followed by mathematical analysis and then encrypted encoding of these facets. Therefore, as a biometric device is not really a comparison of images but rather the very specific data it has collected. Drawing data from the biometric system may lead to little, but the collection of useless data, rather than compromising biometric data of an individual. Some locks and network software programs that connect to them (if they are capable network) also allow blocking programming for a guest user is only kept in memory during a given period of time. At the end of that period, the data is automatically fingerprint minutiae purged from the system.

Biometrics Durability & Appearance

Durability is very simple. Take a look at the lock: is protected from the elements? Some locks have sliding roofs to protect biometric scanning window and buttons from dust, dirt, water and so on. Is the body healthy? Some locks have thicker walls of the alloy in its construction to make stronger, some have plastic parts that make the unit more vulnerable. Is it the end built to last? Some biometrics are "nanotechnology" finishes that make them as high-tech on the outside, as they are inside, and make them highly resistant to scratches that can make them less attractive. Solidly blocks built based on a shroud design can be a bit more expensive but are more robust in terms of security, which of course is what they are there the end of the day.

This leads to the final criterion to consider when buying a lock: it is attractive, and it does add visual (or load) in building. Unfortunately, it appears that many biometric locks were designed with functionality in mind, and little or no consideration was given to appearance, but no no rule etched in stone that a biometric device has to be ugly, and some units are beautiful and elegant and make a strong statement on any door.

Conclusion

When everything is taken into account, take the step to adopt this New technology can be a rewarding experience: just be careful to select the appropriate device for you, your situation and your aesthetic sensibilities ". You might be very rewarded for his care in the purchase, and be able to truly enjoy the best things that this exciting new technology can provide.
