Securing web services for heterogeneous databases consolidation of the national population information system

---

The Indonesian Ministry of Home Affairs is developing a national population information system called Sistem Informasi Administrasi Kependudukan (SIAK). Its purpose is to provide a coordinated and continuous management of national population data. SIAK uses distributed databases to collect and store population data. In order to maintain consistency amongst the data, consolidation needs to be performed. Mainly, there are three problems that need to be solved. First, several different operating systems and database management systems are being used because of existing applications. Second, the databases are geographically distributed across the nation. Finally, there is a lack of continuous online communication because of poor infrastructure. The main focus of this research paper is how to provide secure consolidation under these conditions. We propose the following approaches to solve these problems. Each of the regencies should have their own databases to simplify data entry and storage. There should also be a central database to store the data of all regencies. It is also used to prevent duplicate or illicit citizen's data. The consolidation of these databases is done periodically. We propose the use of web services for the consolidation. The elements of web services used are XML, SOAP, and HTTP or SMTP as the transport protocol. XML is used to structure the data exchanged because it is programming language-neutral. SOAP provides a way to communicate between applications running on different operating systems. The use of HTTP as the transport protocol is suitable for SOAP/RPC, while the use of SMTP is to support one-way notifications. Finally, WS-Security standards are applied for the security of the system. By implementing these approaches, the system's cost can be reduced significantly because the system doesn't require continuous online communication. The performance of the system will improve as well, since less time is required to access the data. The implementation of these approaches will solve the problems.
