Accountability is an important factor for future Internet cloud networks where uncertainties linked to security and personal data protection still represent barriers to universal use. If the family photos you have uploaded are to remain secure, there is a need for explicit agreements between users like you and the cloud service providers. This is the objective of the new A4Cloud (Accountability for Cloud and Other Future Internet Services) project, which is funded by the EU’s 7th Framework Program. The project is made up of four subsidiary projects. SINTEF ICT is responsible for one of these that is designed to address the definition of technical requirements. The project will be launched this autumn with a duration of three and a half years.
