Abstract- Video-based object or face recognition services on mobile devices have recently gained significant attention.Cloud systems start to be utilized for services to analyze user data in the region of computer vision. In these services, key points are extracted from images or videos and the data is identified by machine learning with large database of cloud.Detecting Person-Of-Interest (POI), e.g., fugitives, criminals and terrorists in public spaces is a critical requirement of many law enforcers and police officers. Face recognition applications for airport security and surveillance can benefit from the collaborative coupling of mobile and cloud computing as they become widely available today
