Design of secure location and message sharing system for android platform

Present android-based location and message sharing system asks to input the personal information which fails to protect the privacy of information, has no centralized database which is causing the problem of data management and portability, and one main drawback is unable to have a secured two way communication between webserver and android based application. And this Android-based Location and Message Sharing System (ALMSS) is proposed for solving above mention problem. The proposed system uses Java programming language for android mobile user application, PHP programming language as webserver, MySQL as external database to store the data, JSON as intermediary between android platform and webserver and uses symmetric cryptography while communicating between android device and webserver which finally assures the protection of information.
