基于内容的音频认证水印算法设计与实现摘要随着社会的发展，以及信息技术的普及，一些黑客或者机构会截取篡改一些机密信息，并且一些窃取到信息的人，会进一步把这些窃取到的信息给兜售出去，从而赚取利润。因此对于一些信息技术进行加水印操作，是保护信息技术必不可少的一项技术，本文就是基于内容的音频认证水印算法设计与实现。本文研究了以下内容：首先第一章对基于内容的音频认证水印算法的研究背景还有研究现状以及研究意义进行了探讨；然后第二章分析研究各种现存的有关内容的音频认证水印算法的设计和管理方面的文献资料，对于内容的音频认证水印算法的基础知识进行了了解；接着的第三章讲解了二种内容的音频认证的水印算法；最后第四章对于内容的音频认证水印算法进行了MATLAB仿真，得到了基于鲁棒特征点的音频水印算法的优越性。关键词：水印算法；音频认证；MATLABContent-basedAudioAuthenticationWatermarkingAlgorithmsDesignandImplementationAbstract：Withthedevelopmentofsocietyandthepopularizationofinformationtechnology,somehackersororganizationswillinterceptandtamperwithsomeconfidentialinformation,andsomepeoplewhostealinformationwillfurthersellthestoleninformationtomakeprofits.Therefore,watermarkingforsomeinformationtechnologiesisanindispensabletechnologytoprotectinformationtechnology.Thispaperisthedesignandimplementationofcontent-basedaudioauthenticationwatermarkingalgorithm.Inthispaper,thefollowingcontentsarestudied:Firstly,theresearchbackground,researchstatusandresearchsignificanceofcontent-basedaudioauthenticationwatermarkingalgorithmarediscussedinthefirstchapter;secondly,thedesignandmanagementofvariousexistingcontent-basedaudioauthenticationwatermarkingalgorithmsareanalyzedinthesecondchapter,andthebasicknowledgeofcontent-basedaudioauthenticationwatermarkingalgorithmisunderstood.Inthethirdchapter,thewatermarkingalgorithmofaudioauthenticationfortwokindsofcontentisexplained.Inthefourthchapter,thewatermarkingalgorithmofaudioauthenticationforcontentissimulatedbyMATLAB,andtheadvantagesofthewatermarkingalgorithmbasedonrobustfeaturepointsareobtained.Keywords:watermarkingalgorithm;audioauthentication;MATLAB目录..................................................................................................................5..........................................................................................5......................................................................................................5..........................................................................................................7..................................................................................................................7..........................................................................................7..................................................................................................8..............................................................................................9................................................................................................11.........................................................11.............................................................................................11.........................................................................................................13.........................................................................................................14..............................................................
