Title:
METHOD FOR IMPLEMENTING CLOUD LOCKING OF SENSITIVE DATA BASED ON RECONSTRUCTION TECHNOLOGY
Document Type and Number:
WIPO Patent Application WO/2017/063323
Kind Code:
A1
Abstract:
The present invention relates to a method for implementing cloud locking of sensitive data based on a reconstruction technology. According to the method, binary bytecodes of a mobile application is modified and reconstructed, and an application programming interface (API) related to file operations used by the mobile application is replaced, so that a sub-file system appointed by the cloud is fused with a terminal file system, and the re-constructed application is capable of transparently reading and writing cloud data, thereby achieving the purpose of cloud locking of sensitive data. The method relates to: first carrying out programmed analysis on the existing mobile application to find out a computational logic related to file operations, carrying out corresponding reconstruction, and finally re-generating an application with direct cloud data reading/writing capabilities. The present invention is conducive to improving the security of sensitive data of a mobile phone, and in particular, has importance for users who need to protect sensitive data and do not want to store the sensitive data on a terminal.
