In this paper, we have proposed a flexible encryption blocks selection buyer-seller watermarking protocol integrated the RSA asymmetric encryption system and homomorphism mechanism to protect the ownership of digital contents and fit real life. And consider the secondhand transaction in the real life. We also propose a buyer-reseller watermarking protocol based on the flexible encrypt blocks selection buyer-seller watermarking protocol to offer a solution of secondhand transaction. In our scheme, it's more light data transport requirement than other schemes. All roles in protocol will benefit by their participation. Our scheme can overcome various of the known attacks and security problems in the buyer-seller watermark protocol, such as buyer's right problem, unbinding problem, piracy tracing problem, conspiracy problem, buyer's participation in the dispute resolution problem, man-in-the-middle attack problem and anonymous problem. Furthermore, the seller and arbiter can verify the buyer's watermark without decrypting it in our scheme.

本文除应用RSA非对称式加密与秘密同态机制，提出了一个符合现实生活中买卖交易行为、可弹性调整加密范围数位内容买卖浮水印协定，强化了目前研究中对於数位内容买-卖浮水印协定的安全性，并进一步的考量二手商品交易行为，在可弹性调整加密范围数位内容买卖浮水印协定基础上，提出一个结合数位内容二手买卖与盗版追踪的二手数位内容买卖浮水印协定，达到让参予买卖的角色可以在安全的情形下完成二手数位内容所有权的移转并从中获取相对应利益的目标的数位内容转卖浮水印协定来增强了目前数位内容买卖浮水印协定研究中对於二手交易欠缺之处，解决了数位内容买卖浮水印协定中所可能遭遇的重要安全性议题，如：买方权益、盗版追踪、资讯不连结、共谋、买方需要参与仲裁、中间者攻击及匿名性问题。

Perhaps the ultimate digital time capsule would contain data stored in a physical format, and then encased in a material that will fossilise it nicely.

也许最终的数字时光宝盒将数据以某种物理形式存在，然后包裹在另外一种可以将其很好的化石化的材料中。

As the world is becoming increasingly digital, aggregating and analysing data is likely to bring huge benefits in other fields as well.

当世界逐渐变得更数字化，收集和分析数据可能也会在其他领域带来庞大的利益。

According to Newell and Simon, a physical symbol system is a machine, like a digital computer,that is capable of manipulating symbolic data-adding numbers, rearranging lists of symbols (such as alphabetizing a list of names), replacing some symbols by others, and so on.

按纽厄尔和西蒙的想法，物理符号系统是这样一种机器，就象数字计算机，它能处理符号数据，累加数字，重排符号表（如按字母顺序排列一个名称表），用一些符号替换另一些符号等等。

A digital watermark embeds an imperceptible signal into data such as audio,video and images,for different purposes,including captioning and copyright control.

0引言当前，计算机的普及使得很多文学或艺术作者直接将作品以数字方式记录和存储下来，而网络的飞速发展也为数字作品的传输提供了便利。

The playfulness of "Digital Cubes" does not try to disguise its symbolic parallel to meaningful social interaction; while "Wave Bubble" examines the boundaries of privacy in a conglomerated, technologically intrusive environment,"Freedom Flies" proposes alternative models for social awareness and provides new ways for information freedom and democratization. In the same vain is a suit of software tools called "Open Government Information Awareness" designed to monitor government performances allowing everybody to access official data sets and build profiles of those in the government, reversing the course of big-brother's control on the individuals. Also included in MIT's exhibit is "ScreamBody", a wearable space for screaming. ScreamBody silences the screams so the person may feel free to vocalize without fear of environmental retaliation, and at the same time records these for later release where, when, and how the person chooses.

趣味十足的&数字立方&并不掩饰其社会互动的象征意义；而&飘动的泡沫&则检视了在科技日益无所不在的环境里个人隐私的存在界限；作品&自由飞翔&无疑为民众的信息自由意识和民主化提供了新的选择模式；同样，为监督政府行为而设计的以便于民众获取官方数据的成套软件工具&开放政府信息的觉醒意识&则是个人对政府信息强权控制的反叛；当然还有麻省理工学院的&呐喊的身体&，一个可佩带的用于呐喊的装置，&呐喊的身体&能够对喊叫进行消音处理，能够让喊叫者不必担心周围环境受到呐喊声音的打扰而自由地放声喊叫；并且能够同时记录这些声音，用户可以根据自己的需要任何时间、任何地点都可以再次释放这些喊叫声。

The huge challenge in digital image and video sequence is the great amount of data, which should be compressed and decompressed in practical work.

数字图像视频的突出问题在于庞大的数据量给存储和传输带来困难，因此数字图像视频的处理离不开压缩和解压缩技术。

However, digital watermarking technology can make up the shortcomings of cryptography, because it can protect the decrypted data.

但是，数字水印技术弥补了密码技术的缺陷，因为它可以为解密后的数据提供进一步的保护。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
