Practically, it’s about privacy threat, one of the security threats, which include anti-privacy, virus and hacking. Since there is NO such “security threat free” system in the world while most of the security solutions are passive rather than proactive. So, how to tackle this privacy threat proactively? Sadly, not much can be done technically but two magic words, AWARENESS and TRAINING, which are very often ignored. They are interactive, cyclic and interrelated.
實際上，WhatsApp 是次的改動，可以歸類為”反私隱” 或”私隱威脅”，是安全威脅的一種。（另外兩種是病毒和黑客攻擊。）
世上是沒有“零安全威脅”的系統，同時大多數安全（保安）解決方案都是被動式而不是主動式的。 那麼，如何主動地應對這種私隱威脅呢？ 可悲的是，技術上可以做的實在不多。幸而“安全意識”和“培訓” （可惜它們常被忽略）能另闢蹊徑，提供了有效的應對方案。兩者是循環互動而互為關係的。
