Personal data storage on mobile cloud

One of the key concerns for people about using a mobile cloud is that their personal data on mobile device could be stored on, or accessed by the cloud. A mobile device contains contact lists, text messages, personal photos and videos, calendars, location information, and these data can reveal many things about someone’s personal life. However, a personal computer also stores many such personal data such as photos and other multimedia, chat logs, emails, passwords, financial records or access to such records, calendar and contact lists. Today, thousands of monetary transactions are being done in online shopping sites such as eBay, and Amazon. Therefore, the risks involved in mobile cloud are not necessarily greater than those involved in traditional clouds. However, the issue here is whether the means of handling those risks have been properly implemented in the mobile cloud. Despite reservations, people do tend to use their mobile devices with the cloud. Some recent examples of mobile cloud storage are Apple’s iCloud, Google Drive and Dropbox. Apple iCloud enables users of iOS devices to synchronize their application data such as photos, iTunes music, calendars, email, and messages. An initial 5 GB of iCloud storage is free for an Apple user, with additional storage available for a monthly fee. Although iCloud offers an Apple user an impressive user friendly feature suite (such as Find my Phone), it is only for data related to Apple devices. In contrast, Dropbox is less specialized, but works across heterogeneous platforms including Microsoft Windows, Linux, Mac OS, iOS, Android, and Blackberry. Dropbox also allows sharing stored data with friends, and file revisions.
