Implementation of PDS system with improved security and transparency under cloud environment

In large databases where continuous increase in the volume and detail of data captured by organizations [1] and accessed by different users and at different access levels, need to incorporate the security and transparency during the different kinds of information extraction according to role based access levels. Therefore in this paper an efficient data model for improving the privacy as well as transparency of a data model is proposed. The proposed data model is implemented on the different access levels and a cryptographic security is implemented during data access. Additionally a case study on the governmental organization for distribution of food and fertilizers are reported. The implementation of the proposed security and access control model is provided using JAVA technology. After implementation the performance of the system is evaluated and their performance is reported. The results show the model is efficient and able to prevent the data access for unauthorized access.
