Applying A New Localization Approach Based On Multidimensional Wifi Fingerprinting

Personal sensing devices are becoming more commonplace in everyday life. Unfortunately, radio transmissions from these devices can create unexpected privacy concerns if not carefully designed. We demonstrate these issues with a widely-available commercial product, the Nike+iPod Sport Kit, which contains a sensor that users put in one of their shoes and a receiver that users attach to their iPod Nanos. Students and researchers from the University of Washington found out that the transmitter in a sneaker can be read up to 60 feet away. Through the use of a prototype surveillance system, the researchers could track someone wearing Nike+iPod sensors, plot their location on a GoogleMaps-based website and emai and

Tri Chip is a start-up company striving to make all consumers lives easier day-to-day. This small yet powerful chip can be placed on everyday items, you would care if they went missing. Basically you can place a tag on your keys, purse, and backpack; in essence anything. This chip is going to be equipped with GPS technology so you can locate your item if you misplace or lose it. To find your item you can simply log into our free app and it will tell you where the item is within 5 feet radius. To find the exact location you can opt in for your phone to ring louder the closer you get to it.

Our product, Tri-Chip solves this problem of losing or misplacing items by implementing a small GPS tracker that makes it easier to find your lost items in just a few seconds. Attach, stick, or place our Tri-Chips inside everyday items and keep track of them in the easy to use app. Tri-Chip’s future plans look bright, the company is conservatively projected to sell 300,000 units in the next 3 years. That equates to $9 million in revenue by 2019. Tri-Chip is also planning to conquer different markets like law enforcement, military, and outdoor sports and recreation.

There was an option to rent an interactive table which serves as a hand held GPS device. The users can click on a building a read facts.

This depends on the location of the customer , whether they are indoors or outdoors. Their location helps pinpointing their exact GPS location. They would need to move to an area where they ca receive GPS signal so that the app accurately reflects their current location. If they have a latest phone I'd recommend them to click ‘Pickup Location’ and manually enter in the SAP’s address. Otherwise they might have to request metered service from an UberTAXI .

In 1991 wifi was invented, and as the years go on wifi has been developing and changing in the most incredible ways. Wifi has also changed on how we communicate with people, and how we shop for items. As changes come, trouble also comes with it. In recent years, parents have been blaming wifi for the recent problems their children have been facing. The research and studies that have been conducted shows that an increase in wifi access and coverage does not pose a danger to students in

We live in a hyperconnected world where linking up with someone thousands of miles away is easier than making your own doctor 's appointment, and all that you would need to accomplish this is the nearest wifi password. So its no surprise that we can see how each culture is noticeably influencing many of the other cultures around the world. We can also see how each of these cultures are not entirely unified throughout a country, as people can be effected by their regional location, and even the way they speak. So each culture can become increasingly diverse, and have a variety of different effects on many different people depending on the part of that culture that those people have been exposed to.

If so you should be aware of the new technology that the government is using.”A technology, called the indoor positioning system,could push your worry meter to the max” (DesMarais,2012) she argues that the IPS service could easily track you right down to, say the table you’re occupying in the mall’s food court but as long as your WiFi is on. Desmarais claims that skyhook developed first hybrid location system to use wifi positioning,GPS, and cell tower triangulation to determine the coordinates of a device even indoors.”because we’ve been running the location on about 100,000,000 people are doing we have tremendous amounts of knowledge into overall human behavior”(desmarais,2013). This is significant because skyhook also figures out where all these devices live it also adds demographic data such as age and ethnicity.the author is addressing this issue because when you use a location enabled google service, we may collect and process information about your actual location like GPS signals sent by a mobile

Today the accuracy of GPS navigation is not questioned, however, there are still some Applications that use GPS to plot routes between two points and can be very inaccurate because it is hard to determine the difference between locations [5]. For example if you are on a trail that is not registered a GPS could give you an incorrect route. Also a GPS receiver will give inaccurate readings in a forest or a city with tall buildings because satellites have to send clear signals to GPS

GPS has made our lives so much easier. We don't have to print out directions before heading to an unknown address. GPS-enabled devices we carry with us daily allows us to travel freely without worrying about getting lost. There are also a number of GPS devices to help us keep track of our children. It's a dangerous world out there, and at any moment, we might need to know where our children are located.

Abstract— The proliferation of Location Based Services (LBSs) and Geo Social Networks (GSNs) significantly increase the exposure risks of location information leading to leakage of sensitive information. Location privacy preserving methods are designed to provide a specified level of privacy based on some pre-defined privacy guarantees such as k-anonymity and e-differential privacy. In certain situations, we note that users would need different privacy protection levels based on their relationships and trust associated with the users of the exposed location data. For instance, users of a location-based social network may need a smaller privacy protection level in interaction with their close friends and a larger privacy protection level in relationship with public users. In this paper, we present a privacy aware access control model that provides different location privacy protection levels based on various access control list of users.

Global Positioning System (GPS) technology has been on the market for a number of years now. Originally developed by the military for logistical tracking and navigation, it has seen a number of applications for personal and commercial uses in recent years, with more coming down the development pipeline. GPS uses a constellation of low earth orbit satellites to determine the exact longitude, latitude and altitude of the user or vehicle with the tracking monitor. This location is determined by using trilateration between at least three, and preferably four satellites overhead.

The Global Positioning System (GPS) is used by an almost endless amount of people and professions. Although originally designed for

systems with integrated computational and physical capa-bilities that can interact with humans through many new

evolved from ground penetrating radar systems applied to walls and many applications since 1990’s have been developed to sense beyond a wall from near range. These approaches revolve around basic wave physics to form matched filters for each and every single point in target space. Only Doppler processing is not sufficient since imaging of building contents requires 2-D & 3-D systems. So a concept knows as “multilateration” is used. This uses the fact that the possible locus of a point(transmitter) in
