Facebook Messenger升级隐私功能
Facebook Messenger将引入新的隐私管理，用户可以限制哪些人可以给自己发消息。该功能将很快投入测试，届时用户可以“决定谁可以给您发送信息；谁可以向您发送请求；谁不能向您发送信息。”
Facebook表示，这些功能与Ins提供的功能相似，而Facebook在12月添加了更为精细的信息控件。Messenger还在尝试自动模糊那些不是Facebook好友的用户发送的图像，因为这些图像很多是垃圾邮件或是不当内容。
Facebook said the features were similar to those provided by INS, and Facebook added more sophisticated information controls in December. Messenger is also trying to automatically blur images sent by users who are not Facebook friends because many of them are spam or inappropriate content.
Messenger现在也正式开启了“应用锁定”功能，该功能允许用户在接受信息之前要求对方的面部识别或是指纹认证，为Messenger聊天增加了更多安全性。此功能目前iOS系统可用，且即将推出安卓系统。
Messenger has now officially launched the "application lock" function, which allows users to ask for facial recognition or fingerprint authentication before receiving information, adding more security to Messenger chat. This function is currently available in IOS system, and Android system will be launched soon.
