EFF 的 Privacy Badger

EFF 推出新的延伸套件 (有 Firefox 與 Google Chrome 版),透過演算法阻擋嘗試追蹤你的單位:「Privacy Badger」。

在官網上有比較技術面的說明:

At a more technical level, Privacy Badger keeps note of the "third party" domains that embed images, scripts and advertising in the pages you visit. If a third party server appears to be tracking you without permission, by using uniquely identifying cookies to collect a record of the pages you visit across multiple sites, Privacy Badger will automatically disallow content from that third party tracker. In some cases a third-party domain provides some important aspect of a page's functionality, such as embedded maps, images, or fonts. In those cases Privacy Badger will allow connections to the third party but will screen out its tracking cookies.

技術上的作法是分析 third party domain 的行為,用演算法阻擋可能的追蹤。與 Ghostery 這類工具使用人力建立清單的方法不太一樣。

裝起來跑看看,感覺還蠻有趣的...
