“The most profound technologies are those that disappear .They weave themselves into the fabric of every-day life until they are indistinguishable from it .” Mark Weiser


• Pervasive Computing

– A Web of computing devices and sensors embedded in everyday objects ranging from cars to house.

– The devices are context sensitive and user aware.

INTRODUCTION


Aspects of Pervasive Environment

• User Interaction User interacts with speech, gestures and movements The sensors and communication devices are ‘aware’ of the user and they

are also aware of his/her intent .• Proactively• The computing devices should interact and query devices on transparency.• Technology has to be transparent Behalf on user and his intent.• Device Interaction Frequent multiparty interactions

No central authority or third party


Solution: Biometrics?• Definition

– Biometrics is the science of verifying and establishing the identity of an individual through physiological features or behavioral traits.

• Examples– Physical Biometrics

• Fingerprint• Hand Geometry• Iris patterns

– Behavioral Biometrics • Handwriting• Signature• Speech• Gait

– Chemical/Biological Biometrics• Perspiration• Skin composition(spectroscopy)

Applications

• Health-Care Remote sensors and monitoring technology will allow

continuous capture of human physiological data . Medical staff could be immediately alerted to any detected irregularities. The continuous collection of data could provide accurate pattern/trend analysis of long term conditions such as heart disease, diabetes and epilepsy. Wearable sensors may offer greater patient mobility and freedom within hospitals and save both time and money by reducing the number of repeated testing. Hospital administration could also be transformed .


Environmental Monitoring

• Pervasive computing provides improved methods to monitor the environment.

• It will allow for continuous real time data collection and analysis via remote, wireless devices.


Intelligent Transport System

• Pervasive Computing is being employed to alleviate the traffic congestion and accident costs.

• Electronic devices could be directly integrated into transport infrastructure and vehicles themselves with the aim of better monitoring and managing air, road and sea transport systems.

• The vehicles could become capable of receiving and exchanging information ‘on the move’ via wireless technologies and be able to communicate with devices integrated into the vehicles alerting drivers of traffic congestion, accident hotspots and road closures.


Privacy,Security and Safety

• PrivacyWith personal information transmitted and stored

in greater volume the opportunities of data interception, theft and ubiquitous surveillance(official, unofficial) will be heightened.

PCS could be installed in places considered private and many aspects of personal life could be recorded and stored, with the risk of breaches of privacy.


Privacy,Security and Safety

• Pervasive computing also gives debate over safety. Integrated transport systems could involve road vehicles having actuating devices that intervene in the driving process, possibly responding to hazards more quickly than humans.

For eg:The new Mercedes S-class features an active-braking system that can detect rapidly slowing vehicles in front, activating the brakes without driver intervention. While this may help avoid accidents ,there are also potential risks, for example the security of the vehicles software is breached.


Advantages

• Invisible• Socialization• Decision-making• Information processing• Convergence


Applications


Conclusions

• There is a wide range of potential benefits for government, service providers and consumers as computing technologies become more pervasive.

• There is a debate over how to address concerns over privacy,security safety and sustainability while still realising the benefits of pervasive computing.
