Many users need not worry about privacy risks if they recognize what to do. The new GPS technology allows people to find their way through unfamiliar places. It is a instrument that assists people in finding a restaurant or an ATM in town. As a tracking tool, privacy issues concerning GPS use have been raised. This technology is now being integrated in most models of phones and cameras. Users like its features, from simple photo taking to sharing of information on the internet.

The key point of the issue raised is the risk involved with anybody being able to access the user’s location from cell phone data. Basically, many phones can keep detailed records of where a person has been. Using this data with Google maps, the phone owner’s location data can be easily mapped showing everywhere he or she had been for any period of time.

GPS-enabled phones or cameras save photos using EXIF data which means Exchangeable Image File. The EXIF annotation is used in almost all new models of digital cameras. This enables storage of photos to consist of shutter speed, F number, exposure compensation, ISO number, date and time the image was taken, etc. The foregoing does not pose problems on privacy, but are just information about traits of the stored data. What stirs unease is that some cameras are capable of storing GPS information on the photo so that one can easily locate where it was taken.

Apple and Google have made public their view on the privacy matter. According to them, users should not pass on the accountability of protecting their privacy to others. Even if the technology is there, users still have the ultimate decision of whether or not to use it. Users can simply disable or enable GPS features in their phones. Google also made clear that identification numbers of each phone signal cannot be traced to a specific handset. Google assigns a exclusive signal for each handset as part of each policy.

Some groups do not support the idea of switching off GPS features. GPS technology has been applied in many helpful applications. New phone models are designed to operate a lot of new apps that are location enabled. Not taking advantage of the benefits of this feature will make one’s phone “useless”.

Users can continue to pressure phone manufacturers and lawmakers to set limits on the use of GPS data. They can also trust that the government could move more rapidly in order to catch up with the fast-changing technology. Meanwhile, the best that can be done for the moment is to protect one’s own privacy.

One way of doing this is by limiting data sharing, mainly when using GPS enabled phones and cameras. One should take time to understand what happens to data that they upload to any website, especially social networking sites. Most sites always ask the user whether he or she wants to share the information before posting. This makes privacy the full responsibility of the user.

It is not only phones that can reveal your location. Every time you surf the Internet you are letting others know where you are. To surf anonymously us an anonymous proxy to mask your location.

RFID is the acknowledged acronym for Radio Frequency IDentification. The core of RFID technology is that every RFID chip or tag is capable of emitting a radio signal on a frequency totally unique to itself.

Therefore, every RFID tag must have its own identifying frequency and the RFID tag readers must be sensitive enough to be able to differentiate between frequencies that are only a very tiny bit different from its neighbouring tags. The disparity can be microscopic.

Therefore, the technology needs to be sensitive and discriminating, but not fragile, because the equipment has to be used on the shop floor and by people who are often in a hurry and in weather that may be inclement.

In order for RFID to have the desired result, you have to have a tag, which is an upmarket kind of bar code and a radio receiver, often called a (tag) reader. However, whereas a bar code can only hold a small quantity of information and the bar code reader has to be pointed at it, an RFID tag can hold much more information and can be read from a hundred yards or more – even out of line of sight.

Passive tags will only reveal their information when required to to by a reader, whereas an active tag is constantly relaying its contents. Clearly, active RFID tags are more costly than passive tags, because they require a long life battery.

These tags can be utilized to track items from the moment they leave the manufacturer of the goods they describe to the in-bay of the vendor. The tags can then be up-dated or replaced and stored in the warehouse. Once there, RFID readers can keep management informed about what goods are where and if the sell-by-date is impending.

This has implications for the levels of stock that a company needs to hold, the quantity of goods sold cheap because the sell-by-date is too near and for theft, all of which should boost company profits more than paying for the cost of the tags, the readers, the printers and the programmes.

At the click of a mouse, bosses will be able to read how much inventory they have in real time and if this is all connected to the checkout cash registers, which are the most and least profitable items. This makes reordering simple . Easy to the point of automation. For example, when supplies of the top ten percent of the best selling products falls below 1,000 order 10,000 more. Automatically, no questions asked.

RFID has many other applications as well. The principle mentioned above can be applied to farm animals, a call centre’s computers, a fleet of commercial vehicles, an record of domestic items, your pets, your car and even your garden furniture. Some people who work over a boundary are even having them put under their skin so that they do not have to wait at customs.

And do not forget that criminals on early discharge are also tagged. It is the same technology.

How does one go about taking care of one’s assets – one’s worldly belongings? Well, the majority of people keep their money in a bank, put the jewellery in a strongbox and insure the remainder. But insurance is not really taking care of your possessions, is it? It is taking care of yourself so that you do not have replace them with your own money.

In the old days, and even now, I presume in some places, you would employ a boy to watch over your sheep or cattle or bring them in at night for fear of big cats, wolves or rustlers. These were an early kind of security guard and indeed rich people had and frequently still do have personal body guards.

What if you had a substantial office with a hundred laptop computers – laptops because people had to do field work too? How would you keep track on all those? A car is another good case in point and construction site machinery is being stolen all the time even from under the watchful gaze of (or with the compliance of) private security companies.

So what can you do? Get dogs? That works sometimes, but they can be poisoned. Get video cameras and passive infra-red motion sensors linked to a control centre? That works and a lot of firms and private houses have it, but it is very costly.

As a cheap alternative, the police were giving out free pens in the UK, which wrote in invisible ink. The idea was to write your postcode and house number. This ink became visible under a special kind of light. That is fine if you have a suspect or found property.

Bar codes are not realistic, the pen is better. It all comes back to insurance or surveillance.

However, there is another technique that is becoming affordable. The concept has been around for about 85 years, but it was too expensive to use on anything less significant than an airplane or a battle tank.

I am talking about radio frequency identification or RFID for short. The idea is the same one that aircraft have been using since during the Second World War – a transponder emits precoded information in answer to a request from an RF reader.

Information regarding ownership and details of what the item is can be written to an RFID chip also known as a tag and the tag can then be glued inside the item that it is to protect.

There are two varieties of tag: the passive and the active. Passive tags will only respond if information is requested by a reader, whereas an active tag is always broadcasting.

Many business people use RFID tagging to keep track of their assets. In the instance of farm animals, most cattle are tagged these days. Most large offices have their IT goods tagged as well and we all know that fashion stores have been tagging clothes for years, although maybe you did not know what that button was that they were taking off at the till.

People are already tagging their dogs, cats and cars and it will not be long before these asset management techniques will be used extensively at home too. Insurance companies may demand on it.

An Automatic Identification System, or AIS, is basically an electronic transponder that is usually installed on a boat that identifies it. This is most common in marine locations. The transponder sends out a VHF signal on a continuous basis that provides information about a ship such as it’s name, type, position, and call sign.

This VHF signal is valuable because it relays information to other ships about its course and speed. The final result provides a visual reference about all enabled vessels that are transmitting within a VHF range. This system is important to the safety of water vessels because it helps to track the movement of other vessels within a certain VHF range. This marine identification tool therefore helps to reduce the likelihood of vessel collisions on the water. . The data that is received by other AIS-enabled boats is most of the time shown on a computer screen or positioned as an overlay on a chart plotter. This will help to confirm radar readout.

Navigators and crew members who are on-watch depend on it to make important waterway navigation decisions in terms of course and speed. This system also is a valuable tool to help search and rescue operations. The device can pinpoint the exact position of a ship in trouble regardless of weather conditions.

Dangerous situations can be avoided by programming the system to track specific vessels. This information can be exchanged automatically by the ships captains allowing for safer navigation. Ships with over 300 tons of cargo & all passenger ships are required by the International Maritime Organization to be fitted with the marine guidance system. It is not required for recreational boats but it is increasingly becoming more popular. Globally, it is thought that this technology is is used in more than 40,000 maritime vessels.

The number one use is for avoiding collisions. The tracking does not work alone. VHF radio communications can be limited and considering the fact that every vessel isn’t required to have it, it is not the perfect solution. It is not an automated collision avoidance system as defined by the International Regulations for Preventing Collisions at Sea (COLREGS). In the hands of a skilled captain however, it is one of many tools utilized for safe travel.

Sea captains often need help identifying other vessels in a local area in order to make the best decisions on course. That likewise does not necessarily mean that all additional types of navigational observation is discarded. There is, of course, visual observation where the captain will often use binoculars to position far away obstacles or ships. There can also be acoustic observational warnings that a captain must listen for such as horns, whistles, or VHF broadcast. Last but not least, there is radar or Automatic Radar Plotting Aid (ARPA) that can offer beneficial navigational data to enhance what the AIS is plotting. Even with all this kind of technology, incidents can still happen. It is frequently because of time delays and the natural limits of radar or even just plain human error whenever this takes place. The graphical charts and all the other observational tools must be utilized if water travel is to be safe and AIS is a small part of that.

Radiofrequency ID system has been around since the 1940s and has in no way ceased widening its range of application. RFID is a system with numerous components. It has semiconductor transponders, readers, and software that facilitates continuous data feeds.

An internal circuit and antenna happen to be crucial in every RFID transponder. The IC is implanted with an electronic product code (EPC) rendering it unique among the remaining tagged items worldwide. When the label is inside range of an RFID scanning device, data about the tagged article is sent out over the antenna to the scanner, supplying records to a processing system.

RFID technology was first applied for combatant objectives in the second world war. Subsequently, it’s been engaged in a number of areas. The application grew to become a real benefit in automotive, security, shipping, travel, not to mention a number of other business applications.

Though it was looked at as a wireless bar coding device, RFID is better unequivocally. Scanning with RFID transponder stays reliable even if barriers stand somewhere between the item and the detector. Furthermore, these types of transponders can scan an item as much as 90 feet.

RFID is an autonomous determination system. This determination method performs without human supervision. It is also able to read many IDs concurrently and continues to be accurate in identifying the items.

As a rule, RFID systems are classified in two ways. The first group springs from its storage and recovery functions: Read-only or Read-write and Passive or Active land sources. The next one is based on the frequency it makes use of: Low Frequency, High Frequency, or Ultra-high Frequency.

Read-only labels retrieve recorded data exclusively. Distinct information that can be stored may include a product description or tracking program code. These techniques can easily successfully reduces costs of useful manufacturing and supply chain events. Separately, read-write labels are, conversely, predetermined to just accept input and display or edit output.

In a passive approach, an RFID scanner gives off a power field that sets off as well as powers the tag. With no scanning device within 90 ft, the ID couldn’t render any information. A passive system isn’t really as helpful and is rather inferior with regards to consistency when compared to a dynamic system.

A dynamic scheme has batteries ingrained in tags to assisted in the transmittal of data between tag and scanner. Dynamic systems tend to be more sophisticated than passive systems and scans broader ranges. Also, they are equipped with new features like infrared scanning devices and ultimately have a lengthier life span.
