Disclosed are a method for extracting a fingerprint of a publication, an apparatus for extracting a fingerprint of a publication, a system for identifying a publication using a fingerprint, and a method for identifying a publication using a fingerprint which can easily identify copyright infringement and can effectively protect copyrights. The system for identifying the publication using the fingerprint includes: a fingerprint extraction unit for extracting fingerprints for collected query publications to identify the copyright infringement; a fingerprint query unit for querying fingerprints of original publications corresponding to the fingerprints for the query publications provided from the fingerprint extraction unit; a DBMS for storing the fingerprints extracted from the original publications and additional information from the original publications, and providing a search result candidate group which is composed of fingerprints of at least one of the original publications corresponding to the queries of the fingerprint query unit; and a candidate group verification unit for determining copyright infringement for the query publications by verifying the search result candidate group provided from the DBMS. Consequently, the present invention can easily identify copyright infringement for the publications and can thereby prevent copyright infringement.
