TSPeer - Trust model for spherical Peer-to-Peer overlay networks.

The rise of mobile devices has revolutionized the way we interact with technology, enabling us to carry powerful computing devices in our pockets. However, with the increasing amount of sensitive information stored on these devices, trust has become a crucial factor in mobile security. Fingerprinting, which utilizes sensors embedded in mobile devices to recognize the unique characteristics of the user, has emerged as a promising approach to enhancing trust in mobile devices. Rapid response capability is crucial for the structure of a Peer-to-Peer system, as the nodes within the network have the flexibility to enter or exit at any moment without prior notification. This paper presents a novel approach to trust and reputation of mobile devices that use sensor fingerprinting techniques. Our approach uniquely identifies the nodes in a Peer-to-Peer network based on a spherical overlay such as TSPeer. We also discuss the challenges and limitations of this approach and evaluate it through simulation with real-life data sets.
