Abstract: The present disclosure provides a self-updating method and apparatus for remote assistance. After receiving a startup instruction, a core component of a client automatically sends information associated with a device to a server, and by using the information associated with the device, the server searches for a stored updated extension library that matches the information, wherein the updated extension library is the latest extension library provided by an administer of a manufacturer of a device. After the server sends the searched updated extension library to the core component of the client, the core component saves the updated extension library in an extension library component and dynamically loads the updated extension library, so as to automatically update the client.

Abstract: The present disclosure provides a processing method and apparatus for remote assistance; after receiving a startup instruction, a client sends a request for a verification code to a server; the server generates and returns the verification code to the client; and the client generates and stores a check code according to the verification code and a random code generated locally by the client after receiving the startup instruction. Since the check code generated by the client is generated according to the verification code randomly generated by the server and the random code randomly generated at the local, the uniqueness of the check code is ensured.
