Privacy data protection method and system

Abstract

The invention provides a privacy data protection method and system. The method comprises the steps of S1, mounting a hidden volume to a preset directory, thereby enabling a user to store privacy datain the hidden volume through the directory, wherein the hidden volume is a data storage volume which is created by mapping a virtual disk created based on a dm-crypt technology of a Linux kernel to the tail end of a storage space and does not occupy display capacity of the storage space; and S2, detecting a no-operation duration and a residual storage space of the hidden volume in real time, and if the no-operation duration and / or the residual storage space of the hidden volume meets a preset condition, uninstalling the hidden volume from the directory, thereby enabling the hidden volume not to be displayed in the directory. According to the privacy data protection method and system provided by the invention, deniable encryption of the privacy data is realized.

Description

technical field [0001] The present invention relates to the field of computers, and more specifically, to a privacy data protection method and system. Background technique [0002] With the rapid development of science and technology, the ownership of smart phones has grown exponentially. In particular, the rapid development of semiconductor technology has greatly improved the computing power and storage capacity of smart phones, and users can execute some programs on mobile phones that could only be run on PCs in the past. Moreover, with the rapid development of the mobile application market, smart phones have become an indispensable communication and entertainment tool in people's lives. This also results in a large amount of user privacy data stored in the smartphone. In addition, with the rapid development of mobile Internet and cloud computing technology, mobile office has become a new way of working for major companies. These methods all cause a large amount of sens...

Problems solved by technology

Although these tools and protection methods provide a strong guarantee for the security of private data, however, due to the mobility and volatility of smart phones, the existing protection measures cannot well protect the sensitive information stored in the device.

[0004] For example, attackers can crack the lock screen password of mobile devices through brute force cracking, taint attacks, etc., resulting in privacy leaks
