據(jù)cnbeta網(wǎng)站消息，小米官方回應(yīng)了前些時(shí)間鬧得沸沸揚(yáng)揚(yáng)的“小米未經(jīng)許可上傳用戶數(shù)據(jù)”指控。 在雨果巴拉的谷歌+頁(yè)面上，他回應(yīng)道： 小米是一個(gè)專注于提供高質(zhì)易用移動(dòng)網(wǎng)絡(luò)服務(wù)的公司。我們相信保護(hù)用戶數(shù)據(jù)與隱私是最優(yōu)先的。 我們不在用戶許可前上傳或儲(chǔ)存私人信息或數(shù)據(jù)。我們決定把小米云端短信設(shè)置為一項(xiàng)需要選擇啟用的服務(wù)，并且不再會(huì)自動(dòng)啟用。 同時(shí)，雨果向MIUI用戶與粉絲對(duì)此感到的擔(dān)憂表示了歉意，并感謝了提供了反饋建議的用戶和媒體。

　　雨果巴拉還說(shuō)明了MIUI云端信息處理電話號(hào)碼的機(jī)制：

　　1，發(fā)送/接收者的電話號(hào)碼是標(biāo)識(shí)信息傳遞的主要依據(jù)。IMEI與IMSI也用于追蹤設(shè)備的在線狀況。

　　2，當(dāng)MIUI用戶開(kāi)啟短信或打開(kāi)聯(lián)系人，或新建一個(gè)聯(lián)系人時(shí)，設(shè)備會(huì)將涉及該聯(lián)系人的電話號(hào)碼發(fā)送給小米云端短信的服務(wù)器，并查找該聯(lián)系人的在線狀態(tài)(或者是否是云端短信的用戶)。這使得發(fā)送者能立刻確定是否能發(fā)送免費(fèi)的信息。

　　3，在以上的任何情況中，接收者的電話號(hào)碼只用于查找在線狀態(tài)以及傳遞信息。沒(méi)有聯(lián)系人或社交圖譜的信息會(huì)被儲(chǔ)存于云端，并且，以加密形式的(小米云端)短信也不會(huì)儲(chǔ)存超出必要的用于傳遞信息的時(shí)間。

　　4，今天(8月10日)的OTA增加了額外一層安全措施以加密傳送到云端短信服務(wù)器的電話號(hào)碼。在更新完成后，新用戶或進(jìn)行了工廠重置了設(shè)備的用戶可以從主界面進(jìn)入“Settings >Mi Cloud >Cloud Messaging”或從短信應(yīng)用的“Settings >Cloud Messaging”處手動(dòng)啟用小米云端短信，同時(shí)用戶也可在那里關(guān)閉小米云端短信。

　　雨果巴拉原文：

　　- The primary identifiers used to route messages are the sender and receiver s phone numbers. IMEI and IMSI information is also used to keep track of a device's online status.

　　- When a user sends a text message, if there is an Internet connection available, the Cloud Messaging system will attempt to route the message via IP. If the receiver is offline (i.e. not immediately reachable via IP), the system falls back to sending a normal SMS message from the sender s device.

　　- When a MIUI user opens a text message or a phonebook contact, or creates a new contact, the device connects to the Cloud Messaging servers, forwards the phone number of that contact and requests the online status of the corresponding user, which is indicated by a blue icon when that user is online or gray icon if that user is offline (or is not a Cloud Messaging user). This allows the sender to immediately know whether they can text that user without incurring SMS costs.

　　- In any of these flows, the receiver s phone number is only used to look up online status and to route messages. No phonebook contact details or social graph information (i.e. the mapping between contacts) is stored on Cloud Messaging servers, and message content (in encrypted form) is not kept for longer than necessary to ensure immediate delivery to the receiver.

　　- The OTA system update made available today (Aug 10th) adds an extra layer of security by encrypting phone numbers whenever they are sent to Cloud Messaging servers.

　　- We will continue to make changes and improvements to this architecture as needed over time.
