Security of Sensitive Data on Android Smartphones Using Cloud Storage with Reference to Gravitational Search Algorithm

The focus of this paper is to secure sensitive data on smartphones using cloud infrastructure. Nevertheless, the biggest challenge is data security. This work, therefore, addresses the issues of security of user data by using cloud storage with the development of Solo App v2.1 android application which adopted an Advanced Encryption Standard (AES) for maintaining the confidentiality of data. This will enable smartphones data to remain secure either at rest or in transit. Since numerous threats to mobile phones nowadays have made the issue of security of data on smartphones very critical, hence, the need for the development of such application. Three Android devices were used for the experiments to implement the application. The results are presented using time performance metrics that is based on encryption time and decryption time for each device. The results showed that the work can effectively protect user sensitive data with speed using cloud and when compared with existing works, the results are satisfactory.
