你的資訊足夠安全嗎？
In the wake of Edward Snowden's revelations, a San Franciso privacy group has revealed that all of the major messaging apps have fundamental flaws.
The Electronic Frontier Foundation (EFF) released its Secure Messaging ScoreCard today, evaluating dozens of messaging technologies on a range of security best practices.
The scorecard includes more than three dozen tools, including chat clients, text messaging apps, email applications, and technologies for voice and video calls - and found all of the major players were left wanting.
'The revelations from Edward Snowden confirm that governments are spying on our digital lives, devouring all communications that aren't protected by encryption,' said EFF Technology Projects Director Peter Eckersley.
'Many new tools claim to protect you, but don't include critical features like end-to-end encryption or secure deletion.
'This scorecard gives you the facts you need to choose the right technology to send your message.'
EFF examined them on seven factors, like whether the message is encrypted both in-transit and at the provider level, and if the code is audited and open to independent review.
Six of these tools scored all seven stars, including ChatSecure, CryptoCat, Signal/Redphone, Silent Phone, Silent Text, and TextSecure.
Apple's iMessage and FaceTime products stood out as the best of the mass-market options, although neither currently provides complete protection against sophisticated, targeted forms of surveillance.
Many options—including Google, Facebook, and Apple's email products, Yahoo's web and mobile chat, Secret, and WhatsApp—lack the end-to-end encryption that is necessary to protect against disclosure by the service provider.
Several major messaging platforms, like Mxit, and the desktop version of Yahoo Messenger, have no encryption at all.
'We're focused on improving the tools that everyday users need to communicate with friends, family members, and colleagues,' said EFF Staff Attorney Nate Cardozo.
'We hope the Secure Messaging Scorecard will start a race-to-the-top, spurring innovation in stronger and more usable cryptography.'愛德華·斯諾登（Edward Snowden）的爆料喚起了我們對資訊保安的警覺。來自美國洛杉磯的一個隱私團隊透露，絕大多數的通訊應用都有根本性缺陷。
電子前沿基金會（Electronic Frontier Foundation）今天釋出了一種資訊保安評分卡，它通過一系列最佳安全檢測方法來評估幾十種資訊科技的安全性。
這種卡檢測了三十多種通訊工具，包括聊天客戶端，資訊應用，電子郵件應用程式，以及語音視訊通話技術等等所有絕大多數使用者都需要的助手。
“斯諾登的爆料有力地說明了政府正在監控我們的資訊生活，還在逐步控制所有沒有加密保護的通訊，”電子前沿基金會技術總監彼得·埃克斯利（Peter Eckersley）這麼說道。
“很多新技術宣稱能保護你的隱私，但都沒有諸如整個資訊交流過程資訊加密或資訊保安刪除等關鍵性的功能。”
“而這張卡能很清楚地告訴你選擇什麼樣的技術渠道與別人通訊才是安全的。”
電子前沿基金會通過七道關卡檢測那些通訊工具，包括資訊在傳送中以及接收者手上是否有加密，以及資訊的程式碼是否會被審查，接收者看到的資訊有沒有被其他人看到。
有六項工具通過了以上檢測，分別是聊天安全器（ChatSecure），加密貓（CryptoCat），警覺機（Redphone），潛伏機（Silent Phone），潛伏通訊（Silent Text），以及資訊保安器（TextSecure）。
蘋果公司的iMessage和FaceTime產品成為大眾市場的最佳選擇，雖然它們目前還無法提供對複雜的目標性監控的防護措施。
目前很多大眾選擇——谷歌，Facebook，蘋果的電子郵件產品，雅虎的桌面和移動聊天，Secret，還有WhatsApp，在資訊流通的加密上都存在漏洞，這可是防止服務提供商竊密的必要技術。
幾個最主要的通訊平臺，如Mxit，雅虎Messenger的桌面版，完全沒有加密措施。
電子前沿基金會法務專員內特·卡多佐（Nate Cardozo）說：“我們致力於提高使用者隨時和親友、同事的通訊需求的技術。”
“我們希望資訊保安積分卡可以促進通訊技術相互競爭發展，激勵密保技術實現更有力的改革，走向更實用的道路。”
