The rise in mobile Internet usage and increased reliance on cloud computing have led to increased fear of cloud database security. Mobile cloud computing has emerged as the only promising way of providing solutions for the mobile computing environment, including computation offloading and data binding. This paper discusses the overview of mobile cloud computing features and its prone computing security issues and how to walk over them with the most promising solutions. More specifically, it explores in detail a wide range of threats that may attack the mobile cloud-computing platform and the various devices and applications that work extremely well in supporting and mitigating the wide range of problems related to security issues in mobile applications. Moreover, this paper studies some of the ways to make mobile cloud computing more secure and productive no matter the intensity of the required computation. This study takes into consideration, the most common threats that affect the security issues of the mobile cloud database and its solutions. It is deemed necessary to note that, the duty of various cloud service providers is to keep all mobile cloud data safe. Consequently, they must come up with solutions to the problems affecting the day-to-day mobile-cloud database security.
