Content Reuse Prevention Scheme to Prevent Privacy Invasion of Social Network Service
A Social Networking Service (SNS) is an open service that enables its users to communicate freely without being constrained by time or space. In an SNS, users can share various types of content (such as pictures and videos) with government agencies, celebrities, and many other users online. If a person is able to access the content of another user, that content is automatically downloaded and stored in the \"Temporary Internet Files\" folder in the SNS user's PC. Moreover, the content stored in this folder remains there even when the content owner removes it from his SNS. Thus, the stored content is vulnerable to an invasion of privacy due to malicious user abuse.
