Development of Secure Safety Confirmation System Using Virtual Private Cloud

A safety confirmation system is a system intended to enable users to share information about the extent of damage in the event of a disaster. In recent years, these systems have generally been implemented as a Web system using cloud computing. The configuration used for the safety confirmation system included a Web server and DB server, amongst others, and these resources can be easily procured by cloud computing. In addition, implementation in the cloud has many merits such as a shortened development period and accelerated service start time. However, cloud computing is a system on the Internet; thus, there is concern about the risk of illegal access from the outside and information leakage. The safety confirmation system requires a secure system infrastructure in which to store attribute information and users' personal information. Therefore, a cloud-based safety confirmation system would need to be convenient to use and secure. In this paper, we propose to improve the safety by constructing the safety confirmation system in a virtual private cloud environment. The evaluation of the system showed that it was possible to prevent external illegal access and information leakage and to operate the safety confirmation system such that it was highly convenient to use.
