Abstract

The embodiment of the invention provides a data processing method and device and a machine readable medium. Equipment applied to the method is loaded with a first operating system and a second operating system. The first operating system corresponds to a first execution environment, and a namespace of the first operating system comprises a file. The second operating system corresponds to a secondexecution environment, and a secret key corresponding to the file is stored in the second operating system. According to the embodiment of the invention, the file security can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a data processing method, a data processing device, a device and a machine-readable medium. Background technique [0002] With the popularity of mobile devices and the development of the mobile Internet, mobile devices have become portable electronic devices integrating communication, payment and entertainment functions. At present, personal data such as users' chat records, payment tool passwords, and bank card information are stored on mobile devices; whether these data stored on mobile devices are safe or not has become an issue of increasing concern to users. [0003] A related technology has an FDE (Full Disk Encryption) function. When the FDE function is enabled, all data written to the disk needs to be encrypted first, and all data read needs to be decrypted first. [0004] A related technology has an FBE (File Based Encryption) function. When the FBE fu...
