Privacy Issues Surrounding Biometric Technology

The terrorist attacks on the World Trade Center have provoked in-depth discussion and study of existing security measures, their deficiencies, and how to enhance security to prevent similar terrorist attacks from occurring in the future. Biometric technology has risen to the top of the list as a possible solution. The government is not the only entity exploring biometric security systems. The financial services industry see biometrics as a way to curb identity theft. Biometrics are intrinsic physical characteristics used to identify individuals. The most commonly used biometric is fingerprints but others include, handprints, facial features, iris & retinal scans, and voice recognition.

Soon after 9/11 there were calls for the issuance of national ID cards containing biometric information on an RFID chip implanted on the card. The argument is that national ID cards will increase security by identifying individuals with their unique fingerprints which are much more difficult to counterfeit than standard photo ID cards. There is also a movement toward biometric passports. It looks like biometric passports are coming soon. National ID cards may follow.

Biometric identification is nothing new. Humans have been identifying other humans biometrically since the beginning of time. You recognize people you know by their facial features, their voice, and other biometric features. What’s new is introducing technology into the mix that compares a given biometric with a stored database of biometrics to verify the identity of an individual. An individual place their finger on a fingerprint scanner and the image is compared with the database to verify the person’s identity. Promising as it is, biometric technology has not been without hiccups but biometrics are advancing quickly and becoming more and more prevalent in security systems.

Fingerprints are the most commonly used biometric identifiers. The National Institute of Standards and Technology (NIST) conducted a study that showed single fingerprint biometric systems had a 98.6 percent accuracy rate. The accuracy rate rose to 99.6 percent when 2 fingerprints were used and an almost perfect 99.9 percent when 4 or more fingerprints were used. The study results show that biometric identification is nearly perfect which is not surprising given the uniqueness of human fingerprints.

The US-VISIT program, which is an acronym for United States Visitor & Immigrant Status Indicator Technology, currently requires foreign visitors to the US to present a biometric passport containing 2 fingerprints and a digital photo for identification purposes before being granted admission to the U.S. Of course the biometrics are compared against a vast network of government databases full of known and suspected terrorists and other criminals.

On the surface biometric technology may sound like a panacea but it’s use has raised significant privacy concerns that need to be addressed. Here are six major privacy concerns: storage, vulnerability, confidence, authenticity, linking, and ubiquity.

Critics wonder how the data will be stored and how vulnerable it will be to theft or abuse. Confidence issues center around the implications of false positives and false negatives. Can the biometric data be used to link to other information about the individual such as marital status, religion, employment status, etc.? And finally ubiquity. What are the implications of leaving electronic “bread crumbs” to mark a trail detailing every movement an individual makes?

Until these issues are addressed, privacy advocates will lead a charge to resist biometric technology claiming it as a way for the government to assume a “Big Brother” type of rule as described in George Orwell’s novel 1984. But protest as they may, it’s likely national security concerns and the ability of biometric systems to enhance the security of US border and possibly prevent another major terrorist attack will win out over privacy concerns.

5 Reasons Why Fiber Optic Patch Cables Are Beneficial

In the modern era of technology, fiber optics has started to play an important role in data transfer and communication. The data transfer that happens in these cables is based upon the technology of optical networks. Light waves are encoded and modulated to send and receive data. And fiber optic patch cables play an important role in completing the end-to-end connection of systems using this technology.

First of all, let us understand what makes the optical fiber communication important. The fiber optics makes sure that certain desired properties of any communication are satisfied. And the quality that they maintain with respect to these properties makes using these network cables desirable.

Interestingly, the fiber optic patch cables require being compatible with all these properties to keep up with the network quality. So the attributes desirable of the fiber cables are also good for the patches. Some of the important properties are listed below.

Rate of data transfer: Data of high volume can easily be transferred using the optic cables. In fact, with the mainline network cables, one can transfer terabytes of data every second as done in case of the worldwide Internet exchange data. The same can be said about the fiber optic patch cables. The bandwidth of these cables is extremely high.

Speed of communication: The physical communication happens over modulated waves of light. As a result, the speed of communication is extremely fast with the fiber optic networks. One can use these networks to access real time data across the globe. The patch cables are compatible with the speed and they can transfer data at the same speed as the main network cable.

Absence of attenuation: Attenuation of signal is a critical factor in most of the networks. However, for an optical network, this is practically absent. The data can traverse along the network with no amplifier installed in the route. The patch cables also do not attenuate the data.

Accuracy of transferred data: The transfer of data takes place with a high degree of accuracy. The data suffers from practically no external hindrance. No signal coming form outside really changes anything about the data. As a result, the data transfer preserves the accuracy of information exchange. The fiber optic patch cables maintain high levels of accuracy when it comes to data transfer.

Security factors: Fiber optic patch cables are as secure as the overall optical fiber network. They are extremely difficult to break into and hence the possibility of data leaking out of the network is practically minimal.

All of the above makes using fiber optic patch cables beneficial when it comes to real life application. Make sure that you have got the right patch with the right length and aperture, and you are all set to enjoy the benefits of a secure and high speed communication.

Fashion Jewelry Facts and Care Tips

Why we love fashion jewelry?

Fashion jewelry, also referred to as costume jewelry, is a fun and inexpensive way to express your individual style. Its low cost composition means that it is easy to get your moneys worth of use out of it and allows for a much greater variety of bolder, attention grabbing styles and colors that can be mixed and matched according to your mood or wardrobe.

Caring for your fashion jewelry

Although fashion jewelry doesn’t require much of an investment, it is still important to get the most bang for your buck by taking proper care of your costume jewelry by following a few simple steps:

- NEVER allow fashion jewelry to come in contact with oils, soaps, perfumes, or any harsh chemicals which can fade or even ruin the item.

- ALWAYS remove jewelry before sports, swimming, exercising, washing hands, showering, cleaning, doing laundry, or applying lotions or creams.

- NEVER store jewelry wet. Always dry with a soft cloth before storing.

- When cleaning, be gentle! Use a soft toothbrush and jewelry cleaner that specifically states that it is safe for costume jewelry. Make sure it does not contain acid, alcohol, or ammonia. Only use jewelry cleaner as directed. DO NOT over scrub.

- Store jewelry in a plastic ziploc bag or soft jewelry pouch away from other objects and jewelry items to avoid scratching.

- Store jewelry in a clean, dry, cool, not cold place away from heat and dust.

- Use a jewelry cloth for buffing.

- Regularly check for loose stones.

Fashion jewelry typically consists of three elements:

1. A base alloy such as brass, nickel, aluminum, tin or a combination of metals that has been altered to resemble more precious metals such as silver, gold, or platinum. This is achieved by a variety of methods including:

· tone: Have you ever heard of fashion jewelry that is referred to as silver or gold tone? This means just what the name implies. Tone refers to the color of the metal only. Gold and silver tone jewelry are silver and gold in color but contain no actual gold or silver.

· electroplating: This is probably the most common method. In this process an electric current is used to deposit a thin layer, as little as 2 micro inches (a micro inch is one millionth of an inch) onto the base alloy metal which is immersed in a salt bath solution of the precious metal that will be used to plate the object.

· layering: This method also utilizes the process of electroplating. However, the plated object is immersed for a longer period of time allowing for a much thicker layer of precious metal to be deposited. Layered gold or silver consists of approximately 20-50 micro inches of gold or silver. Although it doesn’t sound like much. This thicker layer results in a much more durable, longer lasting jewelry piece.

· overlay: This method utilizes heat rather than electricity to combine the base metal with the precious metal to form a new alloy. This creates a permanent bond between the metals which creates jewelry that can be as durable and long lasting as the real thing with proper care. Gold overlay jewelry is also sometimes referred to as gold filled. It is generally safer for sensitive skin than costume jewelry made by other methods.

· Technibond: This is considered to be one of the most desirable methods of gold plating because it uses a full 40 micro inches of 14kt gold over .925 sterling silver rather than a typical base alloy. It is the best of both worlds.

· vermeil: This is the top of the line in gold plating. This method uses as much as 100 micro inches of gold over .925 sterling silver and as you can expect is also a bit pricier. It may be worth it for someone looking for something closer to the real thing without paying the exorbitant price for solid gold.

2. Man made stones such as cubic zirconia, crystals, rhinestone, glass, or epoxy are the second component of most fashion jewelry The most popular of which is cubic zirconia because of its physical characteristics. It is used to create simulated versions of precious gemstones such as diamonds, rubies, sapphires, and emeralds. Its sparkly appeal and inexpensive price tag allow for much larger, more glitzy fashion pieces that instantly attract attention. Colored glass can also be used to simulate precious stones and faux pearls. Rhinestone and crystal jewelry is also popular because of its glitzy appeal and color choices. Epoxy and acrylic are plastics that is often used to make inexpensive bead jewelry.

Although typical fashion jewelry consists of man made stones sometimes natural crystals and semiprecious stones such as pearls, topaz, black opal, amethyst, or peridot is used to provide a more fine jewelry appeal.

3. Fashion jewelry may also consist of unusual materials such as wood, stone, and shell which can be either natural or colored.
