Abstract—This paper presents a database service system in which smart device databases are used. Every smart device, such as a smartphone or tablet device, has a relational database management system (RDBMS) as the default. First, an image data collection system is proposed. This system is composed of databases in smart devices as client side databases and a database in a server. The data service should ideally be an online real-time service; however, real-time is not always required. Next, a hash chain protocol called a laced hash chain protocol is presented to preserve the consistency of data transferred from each client to a server. Developing a prototype system consisting of several smart devices with SQLite and a Windows database server with MySQL is an ongoing work.
Index Terms—database system, smart device, image data, hash chain, SQLite
