Pervasive computing also known as Ubiquitous computing (ubicomp) is a concept in software engineering and computer science where computing is made to appear everywhere and anywhere. Eg:laptop computers, tablets and terminals in everyday objects such as a fridge or a pair of glasses.
•It is also termed as ambient intelligence, Ubiquitous computing ,everyware,physical computing, the Internet of Things, haptic computing, and 'things that think’.
Pervasive Computing : You're Already Knee Deep In ItRob Manson
Presentation for Web Directions South 2009 on Pervasive Computing that outlines 5 key metrics that can be used to measure how pervasive computing is collapsing your sense of space.
These measurements can be used to define and refine specific elements of a business model to make your operating and distribution platforms more pervasive.
Ubiquitous computing is one of the most prodiously growing topic which will be covering all facets of life.In the course of ordinary activities, someone "using" ubiquitous computing engages many computational devices and systems simultaneously, and may not necessarily even be aware that they are doing so. This model is considered an advancement from the older desktop paradigm. More formally, ubiquitous computing is defined as "machines that fit the human environment instead of forcing humans to enter theirs".

Secure Network Design with High-Availability & VoIPArpan Patel
Networking, the communication between two or more networks, encompasses every aspect of connecting computers together. With the evolution of networking and the Internet, the threats to
information and networks have risen dramatically and performance has depleted enormously.
As a company grows its business its network design needs to be updated from the existing network
and expand it to accommodate additional users or workloads. But the diculty arises as networks
are being pressured to cost less, yet support the emerging applications and higher number of users
with increased performance. As personal, government and business-critical applications become
more prevalent on the Internet, it is imperative that all networks be protected from threats and
vulnerabilities in order for a business to achieve its fullest potential. Hence a Secure Design for a
network is critical in todays expanding corporate world.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

1. Ubiquitous Computing
……Providing computations and
communications everywhere !!
April 2012
Presenter : 09BCE035 Arpan Patel
Guide: Dr. S.N. Pradhan
Nirma University of Technology
2. Flow of Presentation:
- Issues & Challenges in Ubiquitous Computing
(The Problem Space!)
Research Thrusts
Design & Implementation Problems
- Solutions for Certain Problems
- Various Other Applications
- The Future of Ubiquitous Computing
- Conclusion
18. Security and trust issues in ubiquitous environments:
• Security implies protecting corporate resources
against threats and attacks.
• Security goals includes:
- Access control
- Data confidentiality and integrity
- Availability of services
- Accountability of actions
• Various solutions that are used includes:
- Firewalls
- Virtual private network
18
19. Solutions for Security and Privacy
• Sandboxing
- executing code in a restricted and safe environment.
- restricting access from the code to operating system
functionality.
- highly effective but at the expense of flexibility.
• Certification
- Trusting the code as safe on someone else opinion.
- Most often code being signed by a large corporation.
• The Volume of transmitted data should be kept
Minimum
• Data that require transmission should be encrypted and
sent anonymously (without reference to the owner)
19
20. Proof Carrying Code (PCC)
Attaches additional data to a piece of code which can be
interpreted as a proof of a particular property.
Verify the proof and check whether or not it is valid.
Requires no certification , no restrictions so it strikes effective
balance bet security &flexibility.
Direct Code Analysis
Direct analyses of executable code on client machine.
Removes the need to depend on the external trust of
organizations.
Full flexibility and security.

21. • Biometrics
It is the science of verifying and establishing the identity of an individual
through physiological features or behavioral traits.
Physical Biometrics: Fingerprint, Hand Geometry, Iris patterns
Behavioral Biometrics: Handwriting, Signature, Speech, Gait
Chemical/Biological Biometrics: Perspiration, Skin composition(spectroscopy)
• Biometrics offers a promising solution for reliable and uniform
identification and verification of an individual. These traits are
unique to an individual and hence cannot be misused, lost or
stolen. Biometrics are based on established scientific principles as
a basis for authentication.
• Advantages:
– Uniqueness
– No need to remember passwords or carry tokens
– Biometrics cannot be lost, stolen or forgotten
– Security has to be incorporated in the design stage
– Traditional authentication and access control paradigms cannot scale to
numerous and ubiquitous devices 21
22. Some Possible Applications
Pervasive Computing involving Hybrid (Regular and
Sensor Network-based) Internet works for:
• Natural disaster-specific warning purposes like:
Tsunami Warning, Forest Fire Warning, Volcanic
Eruption Warning, Flood-warning etc
• Large-scale monitoring and tracking purposes like:
Wildlife monitoring, Baggage / cargo monitoring,
Intelligent Transportation Systems, Inter-planetary
Networks, Intelligent Transportation Systems,
Wearable and Vehicular Computing
23. Future of Ubiquitous Computing:
• Pervasive computing is the next generation computing
environments with information & communication technology
everywhere, for everyone, at all times.
• Information and communication technology will be an
integrated part of our environments: from toys, milk cartons
and desktops to cars, factories and whole city areas - with
integrated processors, sensors, and actuators connected via
high-speed networks and combined with new visualization
devices ranging from projections directly into the eye to large
panorama displays.
• Pervasive computing goes beyond the traditional user
interfaces, on the one hand imploding them into small
devices and appliances, and on the other hand exploding
them onto large scale walls, buildings and furniture.
23
24. Conclusion
• Today, people's experience of computer technology is, for the most
part, time-consuming and frustrating. Researchers are looking to
address the increasing, sometimes overwhelming, complexity that
comes with digital living and will explore ways to measurably
simplify the digital experience.
• Much research has yet to be done to determine how to simplify
technology. The challenge grows as devices become more capable
and thus more complex. The complexity increases substantially as
users demand that their digital devices work together seamlessly.
Researchers are starting to leverage machine learning and new
networking and data access techniques to address the challenge of
making digital living less frustrating and more intuitive.
