Data Management Method and Apparatus

摘要

The present invention relates to communications technologies and discloses a data management method and apparatus, so as to solve a problem of customer churn for an operator caused by existing data management. The technical solutions provided in the embodiments of the present invention include: acquiring an operator identification code of a terminal and a preset terminal identification code, where the terminal identification code is not rewritable and uniquely corresponds to the terminal; performing a hash operation on first data by using a preset hash algorithm to obtain a first hash value; detecting whether a signature is consistent with the first hash value to obtain a detection result; and determining whether the terminal has permission to be used according to the detection result. The embodiments of the present invention can be applied to a mobile terminal such as a mobile phone.
