Method and system for protecting information stored in an electronic device against backup and restore attack

摘要

A method and system for protecting information in an electronic device ( 100 ) is provided. The method includes calculating a MAC value ( 112 ) of a meta-file ( 110 ). The meta-file comprises file information of at least one file ( 108 ) in the electronic device. The method further includes tagging the meta-file with an identifier value ( 206 ). The identifier value is the same as a value stored in a secure hardware monotonic counter ( 204 ).
