Abstract

The present invention discloses a disk data protection method and system. The method comprises: when an encryption guard service module receiving a decryption request message sent by a terminal through an interaction program module, acquiring a to-be-decrypted physical partition address corresponding to the request message by querying a preset encryption partition list; the encryption guard service module receiving decryption information sent by the terminal through the interaction program module, decrypting the physical partition address after the decryption information is verified to be correct, and mapping the content of the physical partition address to a newly created folder; and while the terminal performing operation on the content in the newly created folder, the encryption guard service module mapping the operated content in the newly created folder to the physical partition address, deleting the newly created folder after the operation is completed, and performing encryption on the physical partition address. The security of specific partitions is ensured and effective protection of partition data is realized.

Description

technical field [0001] The invention relates to the communication field, in particular to a disk data protection method and system. Background technique [0002] At present, smartphones have become the carrier of various information for users and store a large amount of important information, so they have also become the first choice for malicious attacks. A large part of the security threats of smart phones comes from leaks related to personal privacy and various malicious chargeback software. First of all, when the mobile phone is lost or stolen, it is easy to recover the user's sensitive data. Although the Android platform provides a full-disk encryption solution, there are still security holes in it. When the Android phone is started, the full disk encryption will be completely decrypted after the system starts. Malicious programs can easily steal personal privacy and confidential data from the running Android platform. [0003] When the user starts, it will ask to en...
