Description

一种用于数字内容的记忆卡压缩***的安全方法 技术领域  Security method for memory card compression system for digital content
本发明关于一种具数字内容的记忆卡压縮***安全方法， 尤指 一种对于数字内容的发行有一节制与保护的方法。 背景技术  The present invention relates to a security method for a memory card compression system with digital content, and more particularly to a method for protecting and distributing digital content. Background technique
由于计算机与数字技术的进步使然， 许多创作、 著作的内容， （例如电 影或音乐内容）， 其内容皆被转换成数字影音压缩档案， 再将该档案烧录于 CD、 DVD等影音载体供一般消费者使用。 该创作、 著作的内容， 除电影或 音乐外， 甚至广泛延伸至演讲、 教学录像、 舞台剧等等， 皆可以将内容转 换成数字影音压缩档案 （以下合称为 【数字内容】)。 .  Due to advances in computer and digital technology, many of the content of creations, works, such as movies or music content, are converted into digital video compression files, which are then burned on CDs, DVDs, etc. Consumer use. The contents of the creations and works, in addition to movies or music, and even extended to lectures, instructional videos, stage plays, etc., can be converted into digital audio and video archives (hereinafter referred to as [digital content]). .
然而， 由于压缩与复制技术的纯熟， 前述的数字内容， 无论电影或音 乐内容， 皆容易被形成各种档案格式， 透过各种复制、 烧录等技术予以重 制， 更由于网络推波助澜下， 成为散布的媒介而提供更广面的上传与下载， 使得复制的内容， 更无远弗届地被传递、 扩散。 从而， 数字内容 （尤其是 音乐或电影） 的制作心血以及著作内容， 被科技所提供的环境轻易攻破， 而毫无防备。 也令许多著作人的创作意愿低落， 对于重视智能财产权的现 今文明社会， 不啻为一种极大的发展障碍， 因此如何透过科技防护机制对 于著作内容形成复制的障碍， 以及内容的保护， 为许多影音出版、 发行业 者， 甚或演艺人员以及词曲创作人等高度重视， 更符合我国科学技术基本 法以及相关的科技法令的立法美意。  However, due to the proficiency of compression and copying technology, the aforementioned digital content, regardless of movie or music content, can be easily formed into various file formats, reproduced through various reproduction and burning technologies, and more, thanks to network pushes. Become a distributed medium and provide a wider range of uploads and downloads, so that the copied content is transmitted and spread more indefinitely. As a result, the production of digital content (especially music or movies) and the content of the work are easily broken by the environment provided by the technology, and there is no defense. It also makes many writers' low willingness to create. It is a great obstacle to the development of today's civilized society that values intellectual property rights. Therefore, how to form a copy of the obstacles and the protection of content through the science and technology protection mechanism is Many audio-visual publishers, industry players, and even performers and songwriters attach great importance to it, which is more in line with the legislative and artistic principles of China's Basic Law on Science and Technology and related science and technology laws.
, 目前对于数字内容的著作权保护， 所建立的技术大多对于数字内容， 依据科技保护观念而在载体上进行所谓防 copy的措施， 例如影 Γ、 音乐 CD 等进行防拷贝、 防烧录等。 然而， 数字内容的非法散布， 也包含于被授权 录制厂商， 逾越授权份际所为的超量录制与散布， 换言之， 也就是缺少对 于被授权的录制厂商， 齊一防杜藉由合法的授权， 而从事超量部分的越权 拷贝。 而仅能针对被授权录制厂商进行事后的责任追究， 而缺少一种先期 防范的科技方法， 以预防在先。 发明内容 At present, for the copyright protection of digital content, most of the established technologies are for digital content, and the so-called anti-copy measures such as shadows and music CDs are carried out on the carrier according to the concept of scientific and technological protection, such as copy protection and anti-burning. However, the illegal distribution of digital content is also included in the authorized recording of the manufacturer, and the over-recording and dissemination of the excess of the authorization is, in other words, the lack of authorization for the authorized recording manufacturer. , and engaged in the excess copy of the excess. However, it is only possible to conduct after-the-fact accountability against the authorized recording manufacturer, and lack of a scientific method of early prevention to prevent the prior. Summary of the invention

When it is online, it will be online with the digital content provider to update the number of tablets remotely. The steps are as follows:
A、 数字内容提供端需先输入正确 PIN码方能继续进行下一步骤以控 管档案压缩权限数字内容， 提供端需先定义 Song ID与 Distributor ID后， 方能进行档案压缩与依录制端别进行 PKI加密传送影音压缩加密档予对应 的录制端， Song ID按 EPC定义方式； 区分为国码、 制造商码、 专辑序号 与歌曲序号或下载序号， Distributor ID可用以作事后追究之用， 因使用 PKI 加密， 故只有对应的数字内容录制端方能解密；  A. The digital content provider needs to input the correct PIN code before proceeding to the next step to control the digital content of the file compression permission. The provider needs to define the Song ID and the Distributor ID before the file compression and the recording end can be performed. Perform PKI encryption to transmit audio and video compression and encryption files to the corresponding recording end. Song ID is defined by EPC; it is divided into country code, manufacturer code, album serial number and song serial number or download serial number. Distributor ID can be used for post-investigation purposes. PKI encryption is used, so only the corresponding digital content recording end can decrypt it;
B、 录制端需先输入正确 PIN码方能继续进行下一步骤以控管压片权 限只有对应的录制端方能解密档案；  B. The recording terminal needs to input the correct PIN code before proceeding to the next step to control the compression of the tablet. Only the corresponding recording terminal can decrypt the file.
'· c、录制 进行记忆卡唱片压片时， 若计数器显示为 0， 需与数字内容 提供端进行联机以由其在输入正确 PIN码后， 远程更新压片片数。  '· c. Recording When the memory card is pressed, if the counter shows 0, it needs to be connected to the digital content provider to update the number of tablets remotely after entering the correct PIN code.
5、 如权利要求 3所述的具数字内容的记忆卡压缩***安全方法， 其中 该联机状态， 包括在制作记忆卡唱片时， 需与数字内容提供端进行联机， 进行每一片压片时， 皆需索取授权码与计数器后方能执行， 其步骤如下- 5. The method for security of a memory card compression system with digital content according to claim 3, wherein the online state, when the memory card is produced, is connected to the digital content providing end, and each piece is pressed. You need to request an authorization code and counter to execute it. The steps are as follows -
A、 数字内容提供端需先输入正确 PIN码方能继续进行下一步骤以控 管档案压缩权限； A. The digital content provider needs to input the correct PIN code before proceeding to the next step to control the file compression authority;
B、 数字内容提供端需先定义 Song ID与 Distributor ID后， 方能进行 档案压缩与依录制端别进行 PKI加密传送影音压缩加密文件予对应的记忆 卡唱片制造厂商， Song ID按 EPC定义方式区分为国码、 制造商码、 专辑 序号与歌曲序号或下载序号， Distributor ID可用以作事后追究之用， 因使 用 PKI加密， 故只有对应的录制端方能解密； B. After the digital content provider needs to define the Song ID and the Distributor ID, it can perform file compression and PKI encryption according to the recording end to transmit the video and audio compression file to the corresponding memory. The card manufacturer, Song ID is divided into country code, manufacturer code, album number and song serial number or download serial number according to the EPC definition. The Distributor ID can be used for post-accident purposes. Because of the use of PKI encryption, only the corresponding recording end Can decrypt;
C , 录制端需先输入正确 PIN码方能继续进行下一步骤以控管压片权 限只有对应的录制端方能解密；  C. The recording end needs to input the correct PIN code before proceeding to the next step to control the compression of the tablet. Only the corresponding recording end can decrypt it.
D、 录制端进行记忆卡唱片压片； 因计数器显示为 1， 故压片一次计数 器显示为 0后， 即需由压片软件向数字内容提供厂商索取授权码与新的计数 器 =1， 由此方法， 数字内容提供端方可确实掌控录制端的压片次数， 若录 制端记忆卡唱片压片保护机制失窃时， 因无联机的实时授权， 故有效保护 此记忆卡唱片压片机制。  D. The recording end performs the memory card recording; because the counter display is 1, the tablet once counter is displayed as 0, then the tablet software is required to request the authorization code from the digital content provider and the new counter=1. In the method, the digital content providing end can surely control the number of compressions on the recording end. If the recording end of the recording card is lost, the real-time authorization of the online recording is effective, thereby effectively protecting the recording mechanism of the memory card.
