How to View Chat Big Data Report

Wechat chat records cannot be found on big data cloud computing. WeChat officially responded that "no user's chat records will be kept, and the user's chat content will not be used for big data analysis." Chat content is only stored on the user's mobile phone, computer and other terminal devices. Due to the technical mode that WeChat does not store or analyze users' chat content, it is a misunderstanding that the rumor says "we read your WeChat every day".

Extended data:

From a technical point of view, Tencent will not store all the long-term chat records of everyone on the server, because it is too big and wastes server resources. However, Tencent will save short-term chat records, not delete them on the server as soon as the information is received, but delete the old ones when the temporary chat records reach a certain amount.

So we can receive the latest news on different devices. Both mobile phone WeChat and computer WeChat can synchronize the latest news. Moreover, QQ also has the function of chatting and roaming, which must be stored on Tencent's server.

Tencent security expert TK also explained that it is not only the chat records of various instant messaging apps, but also files, address books, text messages, call records, notebooks, calendars and so on. Everything on the phone is the same, even if it is deleted, it may be restored.

At the same time, there is also a technical field called judicial forensics, in which mobile phone forensics is a very important research direction, and a large number of public papers can be consulted. Some domestic forensics tools can also support the forensics of dozens of instant messaging apps.
