数字作品权属认证系统和方法 Digital authentication system and method works ownership

技术领域 FIELD

[0001] 本发明实施例涉及数字作品认证技木,尤其涉及ー种数字作品权属认证系统和方法,属于版权管理和保护领域。 Embodiment [0001] The present invention relates to a digital content authentication technology of wood, more particularly to digital works ー species ownership authentication system and method, the management and protection of copyright.

背景技术 Background technique

[0002] 网络技术与多媒体技术的发展促进了数字作品的创作和流通,同时也对数字作品的版权保护与监管提出了挑战。 [0002] development of network technology and multimedia technology to promote the creation and distribution of digital works, but also on copyright protection of digital works and supervision challenges. hternet上随时都有大量数字作品在传播,如数码照片、 彩铃彩信、网游动漫、(博客)网络文学、视频、三维动画等,而且涌现了大量以数字作品为商品的政府、企业交易网站及数字作品分享网站。 Any time a large number of works in digital communication, such as digital photos, ring tones MMS, online games and cartoon, (blog) network literature, video, 3D animation and so on hternet, and the emergence of a large number of works in digital merchandise government, corporate and digital trading site work-sharing site. 但由于数字作品存在易复制、易修改等特点,在数字作品流传和交流过程中,经常出现版权所属不清的现象,由此产生的版权纠纷和侵权现象层出不穷。 However, due to the presence of digital works easy to copy, easy to modify other characteristics of the spread of digital works and the exchange process, a phenomenon often unclear Copyright, copyright disputes and violations resulting endless. 如何快速有效对数字作品权属进行认证是对hternet上海量数字作品进行版权保护和监管的基础。 How quickly and effectively to authenticate ownership of digital works is hternet Shanghai amount of digital copyrighted works basis and regulation.

[0003] 数字版权管理(Digital Rights Management,简称DRM)是数字化时代对作品进行版权管理和保护的技术和方法的通称,从世纪之交即开始成为媒体领域乃至整个社会关注的ー个热点。 [0003] DRM (Digital Rights Management, referred to as DRM) is the digital age to work techniques and methods rights management and protection of the generic term, from the turn of the century that is beginning to become a hot media ー areas of concern as well as society as a whole. 现有的各种DRM技术方案或产品试图构造ー个安全的封闭系统,为内容保护构造ー个安全屏障,而封闭DRM系统将衍生出技术垄断等问题。 Various existing DRM technology solutions or product ー trying to construct a safe closed system, ー security barrier to protect the content structure, closed DRM system will be derived from the technological monopoly and other issues. 此外,内容的顺畅流通和便利使用是数字媒体产业健康发展的基本特性,封闭系统将内容图在笼子里限制用户部分合理使用权利。 In addition, the smooth flow of content and facilitate the use of the basic characteristics of the healthy development of the digital media industry, the contents of the closed system diagram restrict users fair use rights section in a cage. 已有DRM技术难以成功的根本原因是将眼光局限在内容保护和作品权利等范围内,缺乏对“模拟漏洞”问题和数字作品快速认定问题的解决方案,其中,“模拟漏洞”长期存在而且在未来必将永远存在,数字作品快速认定则是数字化、网络化条件下管理数字作品的必要条件,就像公民身份证明是现代社会管理的基本条件一祥。 DRM technology has been the root cause of success is difficult to look beyond the range of content protection and rights of other works, the lack of a solution to the "analog hole" problem and digital works quickly identified the problem, where "analog hole" long-standing and in the future will always be there, quickly identified the digital work is a necessary condition for managing digital works in the digital, network conditions, as proof of citizenship is the basic condition of a modern social management Cheung.

[0004] 传统DRM的两条技术路线为:密码学和数字水印。 Two technical routes [0004] Traditional DRM are: cryptography and digital watermarking. 前者以加密、授权方式对数字作品提供保护,后者通过水印嵌入与检测来标识、认定数字作品的权属。 The former encryption, unauthorized manner to provide digital content protection, which is identified by the watermark embedding and detection, identification of the ownership of the digital work. 一方面由于数字作品易于复制、传播,加密的数字作品一旦解密即失去保护,极易出现数字作品破解版大量泛滥于网络的现象;加密的作品在过了保护期限后无法自动解密;同时加密也限制了对数字作品的合理使用(fair use),比如用于教学等非商业的目的。 On the one hand due to the ease of copying digital works, spread, once decrypted the encrypted digital work that is unprotected, vulnerable to the emergence of digital works cracked version of a flood on the network phenomenon; the work can not be automatically encrypted and decrypted when over the term of protection; at the same time also encrypted It limits the rational use of digital works (fair use), for non-commercial purposes such as teaching. 另ー方面,水印嵌入虽然可以不被感知察觉,但对数字作品造成一定程度的失真;水印很难对所有正常的媒体处理操作鲁棒,可能被善意操作或恶意攻击破坏和擦除。 Another aspect ー, although watermark embedding can not be perceived noticed, but cause a certain degree of distortion for digital works; watermark is difficult for all of the normal robust media processing operations, may be operating in good faith or malicious destruction and erasure. 此外,加密和加水印都无法应对“模拟漏洞” 带来的网络侵权问题。 In addition, encryption and processing watermark can not deal with cyber infringement "analog hole" will bring. “模拟漏洞,,是大量存在且无法从根本上杜绝的,现有的DRM技术保护的只是数字作品整个生命周期的一小段,在作品创作、版权注册、发表、交換、消费等环节存在大量泄露机会,只要作品被人欣赏和使用,需要从数字空间进入人类感知的模拟空间, 也就存在被复制、泄露的可能。“模拟漏洞”的ー个典型情况是:用户利用数码设备从电脑屏幕或者其他消费终端设备上采集文本、音视频等数字作品,然后在未经授权的情况下将获得到的既不加密也不含水印的数字作品上传至网络,从而造成互联网上侵权作品泛滥成灾,对版权所有者的权利造成巨大侵害。 "Analog hole ,, is abundant and can not fundamentally eliminate the existing DRM-protected digital technology is just a short work throughout the life cycle, in work creation, copyright registration, publish, exchange and consumption and other sectors there are a lot leak opportunity, as long as the work was to appreciate and use, you need to enter a space simulation of human perception from the digital space, there is also being copied, probably leaked "analog hole" in ー typical situation is: the user the use of digital equipment from a computer screen or collection on other consumer terminals text, audio and video and other digital works, and in the case of unauthorized obtained will be given neither encryption nor digital watermarking works uploaded to the network, resulting in flooded infringing works on the Internet, cause great damage to the rights of the copyright owner.

[0005] 现有技术中,对通过“模拟漏洞”流入网络的大量有版权数字作品进行保护的前提是确认其是否有版权及相应的版权权属,而在版权标识符(水印)缺失或遭破坏、同时又缺乏统ー的数字作品注册与管理平台的情况下,仅依据数字作品名称或标识符难以确认其权 [0005] prior art, on the premise of protecting the "analog hole" a large number of copyrighted digital work flow into the network is to confirm whether it has the appropriate copyright and copyright ownership, and (watermark) or were missing in copyright identifier the case of destruction, while a lack of integration of digital works ー registration and management platform, based only on the digital works hard to confirm their names or identifiers rights
