发明名称 METHOD AND DEVICE FOR FILE PROTECTION
摘要 Embodiments of the present invention provide a method and a system for protecting a file, which belong to the field of information security. The method includes: replacing a secure file header of a file to be protected with its original file header to convert the file to be protected to a secure file; and preventing, by the secure file header of the secure file acquired by the conversion, another peripheral from performing an access operation on content of the secure file. By using this method, in a terminal device such as an Android mobile phone or a computer, without affecting normal use by a subscriber, the protection of files such as multimedia files can be realized and content of a protected secure file in a mobile phone is not allowed to be opened on another device to achieve a purpose of avoiding private information leakage and protecting personal privacy.
