众所周知的可能泄露个人信息的元数据是图片中的 EXIF (Exchangeable image file format),包括相机型号，拍摄日期，焦距等技术信息。即使使用智能手机拍摄，也可能包括拍摄设备，拍摄地点，不少相机应用这些选项是默认开启。Telegram 和 Signal 会自动从待上传的图片中移除所有 EXIF，其他情况下你可以使用自由开源的安卓应用程式 Scrambled Exif (f-droid.org) 在发送之前手动移除它们。

对于职业和 amateur coder (APNews 语)，使用 Git (Software) 十分常见。作为版本控制软件，其会记录历史变更的时间，作者邮件地址等。

Git history 记录了备份被审查机器删除文章的项目端点星的志愿者的一些真实身份信息，共产党当局由此找到了他们，非法拘禁数月，随后安排了表演式起诉。

蔡伟，湖北人，1993年生，原在北京某互联网公司工作，2015年本科毕业于中央财经大学，2018年硕士毕业于清华大学社会学系。
大学期间，蔡伟参与过大学生通识教育夏令营（即立人大学），也在一些青少年教育活动中做义工。

可能由于事件引发的寒蝉效应 (Chilling effort)，一个寻求匿名的开发者不敢用 Git 了。

Background

My first time purchasing games on dmm.co.jp (or FANZA), having experienced the confusing download page(it told me to use Browser’s Save Link As because Chrome doesn’t support dmm downloader) , I extracted game files from 3 separately downloaded rar part.

(No Photo)

There’s one README.txt(filename is in Japanese) and one game folder in extracted folder.

(No Photo)

Fine, the main program must be xxx.exe…

A dialog textbox throwed, as I opened tha main program, I can read Chinese character (or Kanji) , knowing it’s something my PC lack to run the game. And installed SoftDenchi with clicking OK at all.

I submitted my dmm.co.jp user ID and password in first launch.

The problem is, I need to use textractor to read scripts from the game, and translate it to English in read time.
However, there were three independent process for one game.

• koikake.exe
• koikake.bin
• koikake.exe

China’s Internet censorship is a far cry from “building a great wall to prevent exchanges” from technical means. The use of “翻墙” will give people misunderstandings, and in fact legalized the silent “illegal intrusion of computer information systems” by the Chinese government.

Let us look at how the “blocking of specific websites” works in China’s Internet censorship.

DNS pollution

In this process, the distributed malicious nodes launch attacks on Internet users/DNS servers to answer their DNS queries.

RST

During this process, malicious nodes interfere with the TCP connection with a specific network address.

Routing black hole

In this process, the administrator of the audit system interferes with the order of the Internet and establishes a black hole router/AS. [1]And through the border routing protocol to direct network traffic to these black holes.
