Abstract
A method and a system for implementing data secure deletion in mobile terminal are provided. The method comprises determining whether a secure deletion is required to process when receiving a deletion message; putting an address of to-be-deleted data of an EMMC indicated by the deletion message into an unmapped device space of the EMMC when the secure deletion is required; and deleting the address of the to-be-deleted data within the unmapped device space of the EMMC to implement data secure deletion.
Claims15
A method for implementing data secure deletion in a mobile terminal, comprising:
- determining whether a secure deletion is required to process when receiving a deletion message;
- putting an address of to-be-deleted data of an embedded memory (EMMC) indicated by the deletion message into an unmapped device space of the EMMC when the secure deletion is required;
- and
- deleting the address of the to-be-deleted data within the unmapped device space of the EMMC to implement data secure deletion.
A system for implementing data secure deletion in a mobile terminal, comprising:
- one or more processors;
- a memory;
- and
- one or more applications, wherein the one or more applications are stored in the memory and configured to be executed by the processors;
- the one or more applications comprises:
- a determining module configured to determine whether a secure deletion is required to process when receiving a deletion message;
- a storage module configured to put an address of to-be-deleted data of an embedded memory (EMMC) indicated by the deletion message into an unmapped device space of the EMMC when the secure deletion is required;
- a deleting module configured to delete the address of the to-be-deleted data within the unmapped device space of the EMMC to implement data secure deletion.
A system for implementing data secure deletion in a mobile terminal, comprising:
- one or more processors;
- a memory;
- and
- one or more applications, wherein the one or more applications are stored in the memory and configured to perform steps by the processor:
- determining whether a secure deletion is required to process when receiving a deletion message;
- putting an address of to-be-deleted data of an embedded memory (EMMC) indicated by the deletion message into an unmapped device space of the EMMC when the secure deletion is required;
- and
- deleting the address of the to-be-deleted data within the unmapped device space of the EMMC to implement data secure deletion.
