METHOD AND APPARATUS FOR FILTERING USER'S SEARCH WORD TO INTERCEPT ILLEGAL SHARING OF CONTENTS HAVING COPYRIGHT

摘要

A method and a device for filtering user search words to block illegally sharing copyrighted information are provided to block all search words included in a modifiable range for illegally sharing the copyrighted information while effectively blocking illegal sharing of the copyrighted information by blocking search of the copyrighted information. An input unit(10) receives a search word from a user, and a filtering pattern storage(20) stores each filtering pattern for the search words corresponding to copyrighted information. A filter(30) outputs a decision for blocking search of the received search word depending on a comparison result by removing special characters from the received search word and comparing the search word with the stored filtering patterns. A filtering pattern setting unit(40) sets the filtering pattern for the copyrighted information to the filtering pattern storage by receiving the copyrighted information. The filter determines that the received search word is identical with the filtering pattern when the number of graphemes of the search word is identical with the number of graphemes of the filtering pattern.
