目的和功能 Objectives and functions
以工信部,教育部,财政部和国务院新闻办为合作伙伴,绿坝目前有家庭版,厂商版,渠道版,网吧版以及校园版(家庭版与校园版经校验后发现完全一致,没有发现有官员版)。With the Ministry of Industry and Information Technology,Ministry of Education, Ministry of Finance and State CouncilInformation Department as its partners, Greed Dam currently offersFamily, Commercial, Organization, Internet Bar and Campus Editions.
公开宣称的功能: 针对10-16岁青少年,过滤色情图片、色情内容、暴力内容
潜在功能:过滤政治内容? 过滤反审查软件(例如无界)?
Stated features: To protect minors from age 10-16 through the filtering of pornographic and violent images and content.
Latent features: To filter political content? To filter circumvention software (such as Wujie)?
还有一个绿坝网络版,在 [<a target=_blank href="http://www.zzjinhui.com/down/newServerCard.rar" target="_blank">http://www.zzjinhui.com/down/newServerCard.rar[</a> 可以下载。
There also exists a Network Edition of Green Dam, which can be downloaded here (.rar).
适用性 Applicability
虽然产品声明的目标是针对10-16岁青少年,但是产品的约定安装机器并没有选择性,产品缺省假设每台被安装的机器都是青少年使用。目前该产品只提供Windows 版本,对IE、Google Chrome(因为采用了系统的网络设置)有效,对Firefox无效。软件屏蔽的不良信息包括时政类的不良信息,软件并非采用一般软件的安装方式,对Firefox无效,关闭浏览器及将网址加入黑名单无确认。在IE下,对明显属于时政类“不良信息”的信息判断不稳定。对色情类“不良信息”的网页判断较准。换成Firefox后,软件没反应。
Current versions only support Windows; effective only when used inconjunction with Internet Explorer or Google Chrome, it has no effectwhen used with Firefox. The harmful information screened by thesoftware includes politically-related harmful information, and thesoftware relies on non-conventional methods to install, alsoineffective within Firefox, closing the browser and adding the websiteaddress onto a banned list without confirmation. In Internet Explorer,the software's ability to classify clearly political content as"harmful information" is unreliable; for pornographic content, GreenDam is able to make relatively accurate assessments. When used withFirefox, however, the software shows no response.

技术架构分析 Technical Framework Analysis
绿坝-花季护航”所有的文件都安装在系统目录(windows/system32)下,程序菜单没有提供卸载入口,后发现卸载功能在主程序的一个菜单里。在启用“绿坝-花季护航”的图片过滤功能时,软件自动清除的浏览器缓存。All files within "Green Dam-YouthEscort" are installed to the system directory (windows/system32), andwhile no means to uninstall are provided in the Applications menu, theoption to uninstall can be found in a menu within the main program.When launching Green Dam's image filtering function, the softwareautomatically clears the browser cache.
在windows目录下的xstring.s2g存放着该软件所有文件的安装路径。Within xstring.s2g, located inthe Windows directory, there can be found all the installation pathsfor all the program's files.
运行时加载的模块:
驱动: C:Windows\system32\Drivers\mgtaki.sys
服务: C:Windows\MPSvcC.exe
启动项: C:Windows\system32\xnet2.exe
During operation, Green Dam installs the following modules:
Drivers: C:Windows\system32\Drivers\mgtaki.sys
Service: C:Windows\MPSvcC.exe
Launch: C:Windows\system32\xnet2.exe
绿坝将密码用MD5算法转换后,以文本方式保存在C:\WINDOWS\system32目录下的kwpwf.dll文件中。以记事本打开该文件,以“D0970714757783E6CF17B26FB8E2298F”替换其内容后保存,即可将密码恢复为初始密码“112233”。
After Green Dam converts the password using the MD5 algorithm, it savesit in text format within the kwpwf.dll file located in theC:\WINDOWS\system32 directory. When opened using Notepad, if thecontent is then replaced with "D0970714757783E6CF17B26FB8E2298F" andsaved, the password can then be restored to the original "112233".
绿坝的一个设置文件 xnet2_lang.ini中有一行:AOption0_1117=发现不良网站自动向金惠公司报告。在system32中有个filtport.dat的文件,默认内容是FreeGate/8567/tcp Urf/9666/tcp,绿坝的过滤文件。
Within Green Dam installation file xnet2_lang.ini, one line reads:"AOption0_1117=Upon discovery of harmful information, reportautomatically to Jinhui Corporation." Located in system32 in the filefiltport.dat, the default content is "FreeGate/8567/tcp Urf/9666/tcp",suggesting that this is Green Dam's filtering file.

使用测试和算法分析 Performance test and algorithm analysis
通过实际测试和用户反馈,发现绿坝的宣称功能的实现能力并不强,却没有避免在各个层面添加很多没有宣称的功能。部分用户的使用体验和讨论:
Through testing and user feedback, it has been noted that Green Dam'sability to achieve its stated function is in fact not that strong, andhas not avoided including many additional undisclosed functionssituated at various levels. Here is a sample of some users' userexperiences and discussion:

图像过滤 Image filtering
图像检测进程从待检图像队列中获取图像数据,先归一化图像尺寸,然后分离肤色区域和非肤色区域,在对肤色区域关系进行分析后去除干扰,提取区域的特征送入已训练SVM分类器。当图像被检为色情图像后送入人脸检测器,若人脸不是主要部分便确定为色情图像。这套算法的主要问题是,色情图像的识别严重依赖于肤色和肤色形状;而最后使用人脸检测加权判定也只是手工打补丁避免出现大幅人脸识别为色情图像问题的办法,且经验权值可靠性缺乏验证。Theprocess of image detection begins by obtaining
从XFImage.xml可观察到,绿霸使用了OpenCV的haar分类器进行人脸检测。绿霸附带的cximage.dll、CImage.dll、xcore.dll和Xcv.dll也来自OpenCV的库文件。都反映出绿霸主要使用了OpenCV来进行图像方面的处理。不过就像一般国产软件的做法,绿霸大概也无视了OpenCV的BSD许可证。
金惠公司承诺图像检测正检率>90%,误检率<7%,而检出率 = 正检率*色情图像比例 + (1 – 误检率)*(1–色情图像比例),在色情图像占1%时,检出率为93%。
文字过滤
对政治性内容的分析,包括法轮功内容的过滤,使用了北京大正语言知识处理科技有限公司提供的文字过滤引擎HncEng.exe、HncEngPS.dll、SentenceObj.dll,数据文件HNCLIB/FalunWord.lib中还包含以UTF-32LE编码的除法轮功外大量政治和色情有关的词汇。
应用程序控制与过滤
对应用程序使用时间的控制
控制未成年人上网、QQ、MSN及游戏的时间,避免过度沉溺于网络,有效戒除网瘾,
对应用程序的内容控制:
经过测试,发现如果在记事本或者WordPad中输入任何“法轮功”字样,都会关闭应用程序,但是在绘图板和MSN中输入这些字则不会有反应,这也说明其程序的不完备性。
部分反编译的内容发现有多种应用程序是其监控的对象。

00468980 omessenger.exe..雅虎通..wangwang.exe....阿里旺旺....start.exe...

禁止各种网络游戏(如征途、魔兽世界)、聊天(如QQ、MSN)等程序,定制黑白名单过滤实效更强;阻断以代理服务器或代理类软件而躲避网址屏蔽的匿名浏览(如自由门)。 (金惠堵截黄色图像及不良信息专家系统FAQ-20080520)
对反审查软件的屏蔽:例如无界。 会 +经鉴定,是XDaemon.exe、XNet2.exe、gn.exe三个程序相互保护,防止被删掉和结束进程。 这是一种病毒上使用的技术啊 <---[<a target=_blank href="http://tieba.baidu.com/f?kz=591097210" target="_blank">http://tieba.baidu.com/f?kz=591097210[</a> -Dxzine 6/10/09 2:12 AM

网络过滤
“绿坝”通过Winsock2的SPI接口获取发送和接收的数据,对这些数据进行分析,获取HTTP数据,将HTTP数据解协议后,经过URL检测器,不良URL检测器和关键字检测器后,根据检测结果决定是否需要使用图像检测器,通过图像检测将新发现的不良网址提供给系统管理员。
绿坝·花季护航 密码破解 初探
转帖自 [<a target=_blank href="http://bbs.pediy.com/showthread.php?t=91165" target="_blank">http://bbs.pediy.com/showthread.php?t=91165[</a>
%WinDir%\System32\kwpwf.dll 文件里保存了密码的MD5值。软件安装完毕默认密码为112233,那么这个文件长度将是32byte,内容为D0970714757783E6CF17B26FB8E2298F
潜在风险
后门:绿霸本身的安全性就有很大疑问,这样一款小公司开发的软件很容易存在安全漏洞,一旦被黑客发现,则所有安装绿霸的电脑都成为黑客的“肉鸡”,如果其安装量大的话,完全有可能重演“暴风影音断网”的事件。
因为绿坝软件本身的多种不完善性,可能会导致客户端正常软件功能的失效(例如,关闭没有保存的正常工作文档而不提示保存)。
因为该软件所有技术参数的设置,都基于科技人员本人对于什么是色情图片的假设。这些假设反而强化了色情的窠臼和性/别不平等,对青少年不利。

绿坝.花季护航 试用报告
缘起:
作为一个无聊的中年人,我偶尔也会偷偷的上网找点不健康的东西来看看。其实我也挺不好意思的,但是就是管不住自己。所以,当新闻里说,国内开始大力推广 绿坝.花季护航 这款软件,并且要求所有在国内销售的计算机都必须安装的时候,我觉得自己有救了。
我去下载了一个3.16版本,解压以后,却找不到安装文件了。我惊叹:国内的软件日新月异啊,连安装程序都隐身了。不过我还是比较狡猾的,找到了一个叫“绿色上网软件LH-setup3.16.exe”的文件,看来这个就是安装程序了。
我在我的老红帽linux上面运行这个程序,红帽说:你当我傻帽啊?我又把这个文件发到我的手机上,结果手机给退回来了,还发了个短信给我:Plsdo not send files larger than the physical memory of thisdevice。最后,我终于找到一台windows的机器,可以运行了。嗯,以后上网,就用windows了。
安装:
我怀着崇敬的心情,开始阅读《最终用户许可协议》。要说国内的软件这些年是进步了很多,连文档都跟英文接轨了。比如这个协议吧,上来就是一句:“重要!”。我当年要是这么写,早被语文老师打出去了。
协议写的也是很清楚的,比如第一条:
本产品可以过滤互联网上的不良信息,但不保证能不良信息能完全被过滤,也不保证被过滤的信息完全是不良信息。
这句话的意思是:当我倒洗澡水的时候,没准也会把孩子倒出去,没准盆子里还会有脏水,或者孩子的一条腿。
再比如这三条:
6.使用本软件产品由您自己承担风险。在适用法律所许可的最大范围内,不承认任何明示或暗示的担保或条件,包括(但不限于)对可销售性、某一特殊用途的适用性及不侵权的默示担保。
7.在适用法律所允许的最大范围内,即使事先被告知以下情况发生的可能性,在任何情况下不就因使用或不能使用本软件产品所发生的任何特殊的、意外的,非直接的或间接的损失(包括但不限于营业利益的损失、营业中断,商业信息的损失或其它精神上的损失)承担赔偿责任。
8.按本《协议》不对因使用本软件所产生的任何经济、法律纠纷承担任何连带或赔偿责任。
我看到这里,心里有点发毛,这要是安装了以后机器不能用了,怎么给老婆孩子交代啊?人家说了,不承担责任。不过,据说这个是国家推广的软件。我一咬牙,装了!
重启:
装完以后软件要求系统重启,然后我就有点不好的预感。这种预感随着重启过程开始逐渐的蔓延。要说我这台机器虽然旧点,可好歹也有双核2.33G,4G的内存,重启一把也就是两分钟的事情,可是这次貌似很慢。
好不容易看到了登录对话框,我输入了密码,然后就进入了漫长的登录过程,整个过程,从我按enter到看到任务条,长达5分36秒。我同时发现,我的默认桌面风格,被改回了windows那个难看的缺省风格。
灾难:
然后我就看到了一个对话框,上面写着:软件启动失败,请重新安装。
重新安装?!那我要先卸载才行啊。这个时候我才明白,那种不安来自哪里:安装的时候,这个软件从来没有问我应该安装在哪个目录里!
我连忙去找windows explorer的图标,但是这个时候,我的桌面还没有完全显示出来。鼠标到处,都是那个沙漏的样子。好在我在DOS年代的记忆还没有完全磨灭,几个键之后,我已经面对着熟悉的黑色DOS窗口了。
C:\Program Files下面,没有
C:\ 下面,没有
D:\ 下面,没有
控制面板里面的卸载软件,也没有
我去开了windows的事件查看器,居然出错!
我干了什么?我是不是给自己的机器上面装了病毒?Google,百度,救救我!怎么把这个东西删掉?
我启动了firefox,firefox报告,不能访问百度;我启动了chrome,Chrome说:找不到google;我咬了咬牙,启动了IE,IE还没启动完,我已经知道结果了:只有127.0.0.1可以ping,其他的IP都不行。
我呆坐着,忽然笑了:我明白了,这就是这个软件的用处 - 它断开了网络,于是我就不能上网,不能上网,就无所谓不良内容了。我真傻,真的,我以为这是一个脏水和孩子的问题,这个软件连澡盆都扔到窗外了 - 然后它把自己隐藏了起来。
笑了以后,我又有了精神。这次我去开始菜单,找到了这个软件的目录,里面有两个图标:一个是启动软件,一个是帮助文件。启动软件自然是不行的,帮助文件就更搞笑了:里面虽然列出了卸载软件的方法,但是这个页面似乎很不情愿,我打开别的帮助页面都很快,打开这个页面,足足用了三分钟。这还不是最好玩的,这个页面显示:如果需要卸载软件,必须先运行这个软件。
多么精妙的设计:先是断开了网络,然后软件自毁,连卸载都必须先运行。我开始怀疑这个设计师是柯南的粉丝,我可以清晰的闻到密室疑案的味道。
解决:
不过设计的再精巧的系统,总还是有它的漏洞。那个启动程序的图标,就是这个漏洞。右键选属性,把我带到了
C:\windows\system32\下面一个叫gn.exe的程序这里。
删掉这个程序,确认注册表里没有什么乱七八糟的启动运行的东西之后,重启系统,这次我没有不祥的预感,因为重启的速度很快。
登录之后,一切如常,我知道系统里又多了几个垃圾文件,但是至少又可以用了。桌面上面还有个没用的图标,shift+delete,机器提示:
我毫不犹豫的选了Yes.[</td>[</tr>

反正我们在学校也只能听上面安排了,谁和自己的工作过不去呢,没有错误怎么能总结经验走向成功呢,观望吧![</td>[</tr>

Reports: China to require all PCs to have site blocking software
HONG KONG, China (CNN) -- The Chinese government will require allPCs sold in China after July 1 to include software that blocks"harmful" content, news reports said on Monday.
Farmers in China learn how to use the Internet in April 2008 in Guangdong province.
Farmers in China learn how to use the Internet in April 2008 in Guangdong province.
The rule, released on May 19, will require all computers to have "GreenDam," a software program that is designed to block pornography sites,the Wall Street Journal reported.
The software must either be preloaded on hardware or enclosed on compact disc with the computer, the report said.
Industry observers fear the software could be used to bring China's "Great Fire Wall" down to the desktop level.
"Why wouldn't we be suspicious about a government saying all computersmust be sold with this particular software from this particularcompany?" said Charles Mok, chairman of the Internet Society of HongKong.
Green Dam is produced by Jinhui Computer System Engineering Co., whichhas ties to China's military and security ministry, the report said.
Company founder Bryan Zhang told the Journal the software is similar toparental control software in other countries and will transmit bannedWeb sites to computers similar to antivirus updates. Learn more abouthow China monitors the Internet »
A spokesperson for Hewlett-Packard Co. in Singapore confirmed toBloomberg News that China has told them to include web site blockingsoftware.

Mok of the Internet Society fears the software could be used to stopuse of software such as onion routing systems that protect anonymityand circumvent router-based site blockage.
He says requiring software be sold in all PCs could have a chillingeffect on end users. "Whether or not they are really monitoring you,they are still sending a message you might be watched," he said.[</td>[</tr>
