Data access method and device

摘要

Disclosed are a data access method and device. The method comprises: a terminal sending an authentication request to a server, the authentication request being used for requesting the server to verify whether a SIM card in the current terminal is a SIM car bound in the server by the terminal; if the terminal receives an authentication failure message, which is returned by the server, the terminal not permitting a user to access the data in the terminal, the authentication failure message being used for indicating that the SIM card in the current terminal is not the SIM card bound in the server by the terminal. The present invention can solve the technical problem in the prior art that the purpose of increasing data security is not achieved because the terminal and the SIM card are only in a binding state, and achieve the technical effect of increasing data security in the terminal.

主权项

1. A data access method, comprising:
sending, by a terminal, a server an authentication request to request the server to verify whether a Subscriber Identity Module (SIM) card in the terminal is a SIM card bound with the terminal; and in the case the terminal receives an authentication failure message returned by the server, refusing, by the terminal, a user corresponding to the SIM card in the terminal to access data stored in the terminal, wherein the authentication failure message indicates that the SIM card in the terminal is not the SIM card bound with by the terminal; wherein the method further comprises: after the terminal receives the authentication failure message returned by the server, uploading, by the terminal, identification information of the terminal and identification information of the SIM card in the terminal to the server.
