Mobile devices are considered to be the next logical step in social networking as they become more pervasive and are able to establish direct communication with each other. Mobile social networking is a new movement in social networking as people have membership of both a virtual community through an online social network environment, and a physical community where they are located. A move in mobile social networking is the decentralised exploration of friendships. Short-range wireless protocols like Bluetooth enable collaborative applications between mobile devices of users. Unlike conventional centralised social networks that rely upon a central authority to organise the opinions of each member of the social network and protect their personal information, members of a decentralised network are completely autonomous and responsible for their own individual behaviour. When people meet for the first time, they thus need help to determine if they can trust each other. This book presents BlueTrust, a trust model for use in decentralised mobile social networks. BlueTrust focuses on establishing trust between users in close proximity by computing trust levels to support user interaction.

Mobile handheld devices provide powerful capability and functionality making it prominent within public and private environments, allowing information to be processed inside and outside of the organisation's network. Mobile Bluetooth connectivity allows workers to access information in both personal and corporate environments This book, presents an information security evaluation of a Bluetooth-enabled handheld device. It attempts to understand the implications of using a Bluetooth-enabled handheld device in both public and private environments and the risks presented by a mobile workforce using Bluetooth connectivity. Information security risks are evaluated based on research into vulnerabilities, attacks and tools that exist to compromise a Bluetooth-enabled handheld device, while also suggesting a possible Bluetooth penetration testing methodology. A practical assessment is performed for a critical analysis of the information security mechanisms implemented by the Bluetooth-enabled handheld device (PDA) and determining possible recommendations to mitigate identified risks.
