Description

通过数字水印对数字音频版权进行认证的方法 The method for authentication through digital watermarking digital audio copyright

技术领域 FIELD

[0001] 本发明涉及一种数字水印方法,尤其涉及一种对常规音频嵌入和检测数字水印的通过数字水印对数字音频版权进行认证的方法。 [0001] The present invention relates to a digital watermark method, in particular, it relates to a digital watermark embedding and detection conventional audio digital audio digital watermark copyright authentication method.

背景技术 Background technique

[0002] 随着计算机网络和多媒体信息处理技术的发展,使得方便快捷地制作、编辑、复制和传输各种无失真的数字化产品成为可能,如数字化的图像、视频、音频、软件、图形、动画和文本等。 [0002] With the development of computer network and multimedia information processing technology, making quickly and easily create, edit, copy and transfer all kinds of distortion-free digital products as possible, such as digitized images, video, audio, software, graphics, animation and text. 这给人们带来很大便利,也同时带来了许多严重的安全问题。 This gives them great convenience, it also brings many serious security problems. 例如,数字媒体产品的版权保护、软件产品的盗版、数字文档的非法拷贝、各种数字信息的篡改等。 For example, copyright protection of digital media products, pirated software products, illegal copies of digital documents, falsification and other digital information.

[0003] 对于上述问题,人们最初的想法是求助于密码学。 [0003] For the above problem, it is original idea was to turn to cryptography. 密码学是保护数字媒体内容最常用的方法。 Cryptography is the most commonly used digital media content protection method. 数字内容在发送之前先进行加密,合法的用户可以利用密钥来解密加密文件。 Digital content is encrypted before being sent to the legitimate user can use the key to decrypt the encrypted file. 对于非法用户来说,没有密钥文件毫无用处。 For unauthorized users, there is no key file is useless. 然而,密码系统可以保护内容的传输,却无法跟踪合法消费者怎样处理解密后的内容。 However, password protection system can transfer content, but can not track how the contents of the legal process decryption consumers. 此外,加密后的文件因为不可理解而妨碍了数字化信息的传播。 Further, the encrypted file is not available because of understanding impede the dissemination of digital information. 由此可知,加密手段存在着一定的缺陷。 It can be seen, the encryption means there are some flaws. 为此,人们开始寻找新的解决办法来补充密码系统,使内容在解密后,仍可以得到保护。 For this reason, people began to look for new solutions to supplement password system that allows content after decryption, can still be protected.

[0004] 随着对这些问题的深入研究,数字水印(Digital Watermarking)技术产生了,它属于信息隐藏技术(Data Hiding)的范围,最初的目的是作为保护数字版权的补充办法。 [0004] With further research on these issues, digital watermark (Digital Watermarking) technology arises, it belongs to the scope of information hiding technology (Data Hiding), and was originally intended as a supplementary way to protect digital copyrights. 由于水印信息置于所保护的内容之中,在正常使用时也不会被去掉,因此水印技术可能满足上述要求。 Since the watermark information is placed in the protected content, it will not be removed during normal use, so watermarking technology may satisfy the above requirements.

[0005] 数字水印技术利用多媒体信息中存在的冗余信息及人类感知系统的特性,在不影响原始多媒体信息格式和质量的前提下把额外的信息(即水印)隐藏到多媒体信息中。 [0005] redundant information and characteristics of the human perceptual system of digital watermarking technology in the use of multimedia information exists, without affecting the original multimedia format and quality of the additional information (ie watermark) into multimedia information hidden. 数字水印是一个多学科高度交叉的新兴研究领域,它涉及了信号处理、密码学、数学理论、通信理论、编码理论、数据压缩和人类听视觉理论等多门学科。 Digital watermarking is a new multi-disciplinary research field highly cross, which involves signal processing, cryptography, mathematical theory, communication theory, coding theory, data compression and listening to human vision theory and other subjects. 数字水印的提出是为了保护版权,然而随着水印技术的发展,人们已经发现了水印更多更广的应用。 The proposed digital watermark to protect copyright, but with the development of watermarking technology, it has been found that the watermark more wider application. 目前,数字水印技术的应用大体上可以分为版权保护、数字指纹、认证和完整性校验、内容标识和隐藏标识、使用控制、隐蔽通信等几个方面。 At present, the application of digital watermarking technology can be divided into several aspects of copyright protection, digital fingerprints, authentication and integrity checking, content identification and hidden identity, usage control, covert communications.
