Creating Personal, Social, and Urban Awareness through Pervasive Computing

A new book that explores emerging research trends of pervasive computing, providing an overview of the theories, techniques, and practical applications related to the three dimensions of context awareness.

Facebook allows private chat with ‘Rooms’ app

The Facebook Creative Labs team rolled out Rooms today, a new stand-alone mobile app that’s designed to let people create small, topical watering holes on their mobile devices and then invite others to join. Josh Miller, who runs the project for Facebook, says the app was inspired by the forums, chat rooms, and communities of the early Web, but designed for the modern mobile era.

Notifications to rule the smartphone interface

When iOS 8 hits, the notification centre is going to be the most important screen in your iPhone. Interactive notifications will spur all sorts of new behaviours. ┬áSome of these will be simple, like the ability to reply to an email or text message. But they’re powerful in that you can do this without quitting whatever you’re already doing. And this interactivity is not just limited to system apps. Third-party developers can take advantage of this new capability as well, so you could comment on something on Facebook, respond to a tweet, or even check in on Foursquare. But others are going to be radical, stuff we haven’t imagined yet. Once developers begin to really harness what interactive notifications can do in iOS 8 — and they will — it’s going to cause one of the most radical changes since third-party apps. With the advent of iOS 8, notifications are the new interface frontier.

Hiding in the Mobile Crowd: Location Privacy through Collaboration

Location-aware smartphones support various location-based services (LBSs): users query the LBS server and learn on the fly about their surroundings. However, such queries give away private information, enabling the LBS to track users. We address this problem by proposing a user-collaborative privacy-preserving approach for LBSs.

CROWDSENSING: The 1st International Workshop on Crowdsensing Methods, Techniques, and Applications

With phones in their pockets, millions of people have access to sensing, computation, and connectivity, making it possible to harness the power of the crowd to collect and share data about their surroundings and experiences on a massive scale. Crowdsensing is a novel data collection paradigm that leverages this vast mobile sensor network, making it possible to expand the scope of research endeavors and address civic issues. This new data collection paradigm introduces several research challenges, including the need for usable and transparent privacy controls, incentive mechanisms, and approaches that transform large-scale user-generated data sets into meaningful information. This workshop provides a forum for discussion, debate, and collaboration focused on ideas, trends, techniques, and recent advances in crowdsensing.


Restoring the privacy and confidentiality of users over Mobile collaborative learning (MCL) environment

Mobile collaborative learning (MCL) is extensively recognised field all over the world. It demonstrates the cerebral approach combining the several technology to handle the problem of learning. MCL motivates the social and educational activities for creating healthier environment. To advance and promote the baseline of MCL, different frameworks have been introduced for MCL. From other side, there is no highly acceptable security mechanism has been implemented to protect MCL environment. This paper introduces the issue of rogue DHCP server, which highly affects the performance of users who communicate with each other through MCL. The rogue DHCP is unofficial server that gives incorrect IP address to user in order to use the legal sources of different servers by sniffing the traffic. The contribution focuses to maintain the privacy of users and enhances the confidentiality. The paper introduces multi-frame signature-cum anomaly-based intrusion detection systems (MSAIDS) supported with innovative algorithms, modification in the existing rules of IDS and use of mathematical model. The major objectives of research are to identify the malicious attacks created by rogue DHCP server. This innovative mechanism emphasizes the security for users in order to communicate freely. It also protects network from illegitimate involvement of intruders. Finally, the paper validates the mechanism using three types of simulations: testbed, discrete simulation in C++ and ns2. On the basis of findings, the efficiency of proposed mechanism has been compared with other well-known techniques.

Auto-diary turns every action into part of your story

EVER given up keeping a diary because you never remembered to fill it in? Don’t worry, your cellphone could soon be helping you write one. A team at McGill University in Montreal, Canada, is tapping into the wealth of information that your smartphone sensors collect to automatically describe your daily activity in the form of a timeline.
