Kim Young-Sam, Seung-Hyun Kim, Jin Seung-Hun · International Conference on Advanced Communication Technology · 2010
As developing the internet a variety of services emerge and service providers serve services such as using users' private information. Service providers require many types of information related users even including sensitive private information to serve a service with high quality, but users are reluctant to disclose their private information. Because if the private information is leaked it will lead to an invasion of privacy of users and may arise some problems about users' life. Nevertheless, service providers want to collect the users' information because of increasing their efficiency of services. As a result, it brings about a conflict of the loss and gain between users and service providers.
