你的信息足夠安全嗎？
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信息安全的警覺。來自美國洛杉磯的一個隱私團隊透露，絕大多數的通信應用都有根本性缺陷。
電子前沿基金會（Electronic Frontier Foundation）今天發佈了一種信息安全評分卡，它通過一系列最佳安全檢測方法來評估幾十種信息技術的安全性。
這種卡檢測了三十多種通訊工具，包括聊天客戶端，信息應用，電子郵件應用程序，以及語音視頻通話技術等等所有絕大多數用戶都需要的助手。
“斯諾登的爆料有力地說明了政府正在監控我們的信息生活，還在逐步控制所有沒有加密保護的通信，”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，但都沒有諸如整個信息交流過程信息加密或信息安全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信纔是安全的。”
電子前沿基金會通過七道關卡檢測那些通訊工具，包括信息在傳送中以及接收者手上是否有加密，以及信息的代碼是否會被審查，接收者看到的信息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），以及信息安全器（TextSecure）。
蘋果公司的iMessage和FaceTime產品成爲大衆市場的最佳選擇，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。
目前很多大衆選擇——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，在信息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：“我們致力於提高用戶隨時和親友、同事的通訊需求的技術。”
“我們希望信息安全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。”
