Method for extracting fingerprint of publication, apparatus for extracting fingerprint of publication, system for identifying publication using fingerprint, and method for identifying publication using fingerprint

Abstract

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.

Description

technical field [0001] The present invention relates to content identification, more specifically to a method for extracting fingerprints of publications, a device for extracting fingerprints of publications, a system for identifying publications using fingerprints and a method for identifying publications using fingerprints. Background technique [0002] Contents or digital publications containing text and images are easily copied, and thus illegally disseminated through various means such as the Internet or P2P. The above-mentioned illegally disseminated content not only caused direct economic losses to the author, but also indirectly reduced the author's enthusiasm for creation. [0003] In order to prevent the illegal dissemination of content and protect copyright, the following existing technologies are used: Digital Rights Management (Digital Rights Management), which packages and encrypts content, so that when selling or purchasing content, the purchase behavior occur...

Problems solved by technology

However, when decrypting the encrypted content or unpacking the packaged content, the content may be illegally distributed

For example, after the digital copyright encryption protection technology applicable to a specific e-book reading device was attacked by hackers, the electronic publications used for the above-mentioned e-book reading device were illegally distributed without reason

[0008] In addition, recently, with the development of technologies such as digital cameras, scanning equipment, and computers, as well as the development of image processing technology, the duplication of analog or digital publications has become more convenient and delicate, and thus users have illegally leaked analog or digital publications as an excuse. purpose, so as to generate digital files and disseminate them. In this case, it is difficult to judge whether it is illegal dissemination or whether it infringes copyright
