Abstract

A hyper text reading system which assures an advantage by protecting the right of a contents provider. A link source confirmation unit confirms a link source of an anchor included in a hyper text. The link source is provided between a WWW browser and a helper application, thereby enabling contents data to be referred from only the anchor included in the hyper text prepared by the contents provider.
