Abstract

The embodiment of the invention provides a data privacy method and device based on an embedded universal integrated circuit card. The method includes the steps that it is determined that a terminal device is not held by a legal user; an eUICC on the terminal device is set to be in a down state; the eUICC is instructed to perform privacy processing on data on the eUICC through the terminal device. By the adoption of the technical scheme, privacy can be performed on the data embedded into the eUICC of the terminal device after the terminal device is lost.

Description

technical field [0001] The present invention relates to communication technology, in particular to a data security method and device based on an embedded Universal Integrated Circuit Card (eUICC for short). Background technique [0002] The traditional Universal Integrated Circuit Card (UICC) is customized by the mobile operator, and contains the relevant information of the mobile operator when it leaves the factory. Once it leaves the factory, the operator information cannot be changed. The eUICC is a UICC embedded in a terminal device, allowing its remote management, such as downloading / deleting mobile operator data, switching mobile operator networks, etc. [0003] For eUICC, after the terminal device is lost, the user can contact the mobile network operator (Mobile Network Operator, referred to as MNO) customer service or go to the business hall to report the loss. After receiving the loss reporting service request, the mobile operator only needs to update the subscript...
