An assessment of the proportionality of regulation of ‘over the top’ communications services under Europe's common regulatory framework for electronic communications networks and services

‘Over the top’ communications services such as Skype and FaceTime are changing the way we communicate, carrying voice and video traffic over the Internet. Unlike traditional mobile and fixed line alternatives, these services fall outside the reach of the common regulatory framework. Whilst an absence of regulation is not appropriate, neither is subjecting these services to the full gamut of regulation the path forward: an analysis of the core elements of the regulatory frameworks reveals that, in respect of data retention and privacy, harmonisation of regulation is appropriate. The remaining challenge is determining whether effective regulation could indeed be imposed on services offered from outside the EU.     

A study on the forensic mechanisms of VoIP attacks: Analysis and digital evidence

This paper discusses the use of communication technology to commit crimes, including crime facts and crime techniques. The analysis focuses on the security of voice over Internet protocol (VoIP), a prevention method against VoIP call attack and the attention points for setting up an Internet phone. The importance of digital evidence and digital forensics are emphasised. This paper provides the VoIP digital evidence forensics standard operating procedures (DEFSOP) to help police organisations and establishes an experimental platform to simulate phone calls, hacker attacks and forensic data. Finally, this paper provides a general discussion of a digital evidence strategy that includes VoIP for crime investigators who are interested in digital evidence forensics.
