Find out what is Ubiquitous Computing?

Lesson Objectives Identify the benefits and concerns of using cloud computing and cloud storage. Understand the term ‘Ubiquitous computing’ Be able to give examples of Ubiquitous computing. Explain the benefits and concerns with ubiquitous computing.

Cloud computing and cloud storage Data and files may be available anywhere in the world where there is an internet connection As the files are being stored by the host, you have no control over them. You need to be aware of their security terms and policies. The host might not be using the latest, fastest and most secure version You only pay for the storage that you have used. You don’t have to provide and maintain hardware locally The speed of retrieval of data may be slower than it would be in the local database held in-house You need to be able to get through to the host to access and process data Benefit Availability Concern

RFID Radio Frequency Identification systems Ubiquitous Computing RFID Radio Frequency Identification systems

What is Ubiquitous computing Ubiquitous means ‘everywhere’ Processors (computers) can be embedded in any device including clothing, Appliances vehicles, buildings and people to connect them to the internet.

Radio Frequency Identification (RFID) Currently RFID chips are used for Ubiquitous computing. These chips use radio waves to transfer data to a tag on a person or object. These tags contain information that is stored electronically. It is similar to a bar code but does not need to be scanned.

Examples Cat flaps that only open when the correct animal that has a chip on their collar. Oyster touch cards to pay for travel in London. Agriculture – monitoring the health of livestock.

Find three more examples and explain the benefits for each. http://www.simonsothcott.com/2011/11/what-is-rfid-10-examples-of-rfid.html http://www.pixelpod.co.uk/blog/2008/12/04/12-examples-of-rfid-across-industries/ http://www.rfidc.com/docs/introductiontorfid_technology.htm

Government Government – The U.S. Department of Defence is planning to use RFID technology to trace military supply shipments and in soldiers. Benefits: this means that if any of the military supplies go missing they can track them and they can track soldiers.

People tracking People Tracking – The United Nations uses RFID technology to track the movements of its personnel. Disadvantages: people disagree with having their lives tracked Benefits:if everyone had one there would be a reduction of crime and birth cetificates etc would not be needed.

pharmaceuticals Pharmaceuticals – Pharmaceutical companies have embedded RFID chips in drug containers to track and avert the theft of highly controlled drugs, such as OxyContin
