This is a comprehensive study about creating secure data stores for mobile platforms such as iOS, Android, Windows OS, etc., that would help a user by securely storing his/her entire life's events and data thereby assisting him/her with querying over them. These queries can be based on dates or a specific geographical location. Data stores could either be local (a database) or on cloud and will be under a complete ownership of the user. We will present this study taking iOS as an example platform of implementation with Dropbox serving as a platform for cloud storage and SQLite serving as a platform for local storage. |
