Collusion is a major unsolved security problem in online bridge: by illicitly exchanging card information over the telephone, instant messenger or the like, cheaters can gain huge advantages over honest players. It is very hard if not impossible to prevent collusion from happening. Instead, we motivate an AI-based detection approach and discuss its challenges. We challenge the AI community to c...

Originally regarded as a tool for social communication among teenagers, Instant Messaging (IM) technology has taken practitioners and researchers by surprise with its rapid proliferation in the workplace. While gaining valuable insights from existing IM literature, we identify the gap whereby researchers have neglected to pay attention to the processes that may shape users’ perceptions of and b...

Retaining users and facilitating their continuance usage are essential for mobile service providers to increase both revenues and profits. This research integrates the perspectives of network externality and switching costs to propose a model for investigating the continuance usage of mobile instant messaging services. Network externality arises from both direct and indirect sources and is conc...

Instant messaging applications (apps) are one potential source of evidence in a criminal investigation or a civil litigation. To ensure the most effective collection of evidence, it is vital for forensic practitioners to possess an up-to-date knowledge about artefacts of forensic interest from various instant messaging apps. Hence, in this chapter, we study America Online Instant Messenger (ver...

Instant messenger programs such as ICQ are often used by hackers and criminals for illicit purposes and consequently the log files from such programs are of interest in a forensic investigation. This paper outlines research that has resulted in the development of a tool for the extraction of ICQ log file entries. Detailed reconstruction of data from log files was achieved with a number of diffe...

Instant messenger programs such as ICQ are often used by hackers and criminals for illicit purposes and consequently the logfiles from such programs are of forensic interest. This paper outlines research in progress that has resulted in the development of a tool for the extraction of ICQ logfile entries. Detailed reconstruction of data from logfiles was achieved with a number of different ICQ s...

We provide a survey on security features and threats to existing Instant Messaging (IM) networks and discuss how currently available systems fail to provide adequate security in light of existing threats. Our discussion and analysis provide a starting point from which to advance academic research in the area of secure IM systems, enabling security improvement in the longer term.

All spellers do not modify randomly when they use Digital Writing in Instant Messaging. Some letters are written, not written or replaced and we tried to provide in-depth understanding of the underlying reasons for the phenomenon. One could choose to type the word “arrête” with one “r” (since all the other letters have a basic value, or the most frequent value) as s/he may consider the other “r...
