Facing precarious status quo of that users' information data in social software is easily leaked, we have carried out a research on secured self-destructive service platform of social software for data. We make full advantage of WeChat, combining TLS protocol, a self-destructive method based on network and OAuth2.0, an open protocol to allow secure authorization from the third party webpage of WeChat to construct a secured self-destructive service platform based on Wechat. We ensure the safety of data transmission between client and server by TLS protocol, take a modified method based on network as the secured self-destructive scheme for data on the server side and make the advantage of OAuth2.0 which is a secure authorization from the third party webpage of WeChat to accomplish users' identification. theories and example analysis verifies the feasibility and safety of this design plan
