Efficient Fair Conditional Payments For Outsourcing Computations, Xiaofeng Chen, Jin Li, Willy Susilo
Efficient Fair Conditional Payments For Outsourcing Computations, Xiaofeng Chen, Jin Li, Willy Susilo
Professor Willy Susilo
The outsourcing computations in distributed environments suffer from the trust problems between the outsourcer and the workers. All existing solutions only assume the rational lazybut- honest workers. In this paper, we first introduce the rational lazy-and-partially-dishonest workers in the outsourcing computation model. In addition, we propose a new fair conditional payment scheme for outsourcing computation that is only based on traditional electronic cash systems. The proposed construction uses a semitrusted third party T to achieve the fairness and efficiency. However, is only involved in the protocol in the exceptional case, namely in the case of disputes. Moreover, since neither the …

Saint Augustine of Hippo (354-430 CE) [1] one of the most revered doctors of the ecclesia catholica, might not have been so highly esteemed had he fl ourished centuries afterwards in a world of uberveillance [2]. One of the unique aspects of Augustine's life that endeared him to the community of the faithful, both past and present, was his rising up from the "fornications" [3] and the "delight in thievery" [4] to become a paradigm for both the eastern and western churches of the penitent who becomes a saint.

Radio-frequency identification has a great number of unfulfilled prospects. Part of the problem until now has been the value proposition behind the technology- it has been marketed as a replacement technique for the barcode when the reality is that it has far greater capability than simply non-line-of-sight identification, towards decision-making in strategic management and reengineered business processes. The vision of the Internet of Things has not eventuated but a world in which every object you can see around you carries the possibility of being connected to the internet is still within the realm of possibility. However incremental innovations may see …

Women In Ict: Guidelines For Evaluating Intervention Programmes, Annemieke Craig, Julie Fisher, Linda Dawson
Associate Professor Linda Dawson
Many intervention programmes to increase the number of women in theInformation and Communications Technology (ICT) profession have been implemented over the last twenty years. Detailed evaluations help us to determine the effectiveness of these programmes yet few comprehensive evaluations appear in the literature.The research reported here describes an investigation of the evaluation of the intervention programmes focusing on increasing the enrolment and retention of females in ICT in Australia. This paper describes an empirical study which explores how evaluation has been and might be conducted and concludes with guidelines for evaluation for those developing programmes for increasing the participation of …

Radio-frequency identification (RFID) tags and transponders have traditionally been used to identify domesticated animals so that they can be reunited with their owners in the event that they stray. In the late 1990s, industry started to investigate the benefits of using RFID to identifying non-living things throughout the supply chain toward new efficiencies in business operations. Not long after, people began to consider the possibilities of getting RFID tag or transponder implants for themselves. Mr Amal Graafstra of the United States is one of the first, and probably most well-known ‘do it yourselfer’ (DIY) implantees, who enjoys building customized projects …
