內容簡介
TalkBack 是一個基於公開金鑰密碼學的開源安全 LinkBack 機制，旨在從根本上解決博客垃圾郵件問題：與 Akismet 透過內容分析檢測垃圾郵件不同，TalkBack 通過阻止垃圾郵件發送 LinkBack 通知來預防垃圾郵件。安裝 TalkBack 後，會將以下兩行防禦添加到您的博客中：
第一道防線是一個輕量級的公開金鑰基礎建設（PKI），通過使用公開金鑰密碼學來確保博客的身份。此外，使用密碼學可以保證 TalkBack 通知不被人篡改，並且接收者可以接收它們而不被更改。
第二道防線是 TalkBack 授權機構強制執行的全局速率限制系統，確保使用單個博客身份，垃圾郵件發送者無法大量發送 TalkBack 感知的博客。
TalkBack 與所有其他防禦機制兼容，不存儲/公開有關您的博客或您的任何私人信息。事實上，如果您不信任網絡，TalkBack 還可以加密您的通知，以保護它們免受窺探者的侵害。

原文外掛簡介
TalkBack is a open-source secure LinkBack mechanism based on a public-key cryptography that aims at tackling the blog spam problem at its root: instead of detecting spam via the content analysis like Akismet, TalkBack prevents spammers from posting LinkBack notifications. When installed TalkbBack add the two following lines of defense to your blog:
The first line of defense is a lightweight PKI (Public Key Infrastructure) that ensures the identity of blogs by using public key cryptography. Moreover using cryptography allows TalkBack to guarantee that no one can tampers with your TalkBack notifications and that the receiver will received them unaltered.
The second line of defense, is a global rate limiting system enforced by the TalkBack authorities that ensures that with a single blog identity, a spammer cannot massively spam TalkBack aware blogs.
TalkBack is compatible with every other defense mechanism and do not store/disclose any private information about your blog or you. As a matter of fact if you don’t trust the network, TalkBack can also encrypt your notification to protect them from eavesdroppers.
