Cloud technology based Information System for testing and certification centers

Nowadays, the vehicles authorization which circulates on the Moroccan roads is delivered by local centers of technical visits which are approved by the Moroccan transport ministry. After investigation, we have raised a crucial problem concerning the internal security of the information systems of these centers. Indeed, each visit center operator can violate the professional rules and positively modify the measure values taken (braking, suspension, emission rate of CO2 gas ...) of a vehicle at the origin unfit and provide it a positive authorization for circulation. Authors of this work propose an efficient solution based on a Cloud architecture to prohibit any human intervention in the process of vehicles control. The measurements performed by each control machine are sent directly to a national cloud which holds the database of all vehicles subject to a technical control. All data access and tampering operations are then detected.
