Special Issue Paper


In the ubiquitous Web environment which exploits real-time image processing methods, easy access to a variety of digital contents such as movies, e-books, and digital songs significantly enhances people’s quality of life. However, most digital content sites do not provide a concrete mechanism to prohibit minors from accessing harmful content, even though a few mechanisms are available in the market to screen out minors from accessing inappropriate content. This paper proposes a fundamental approach that confirms the age of a user using his digital signature with the X.509 certificate when the user attempts to access specific digital content. Its performance is verified by the implementation of the approach.
