METHOD FOR IMPLEMENTING SOFTWARE TOOL FOR USE IN USB FLASH DISK PRIVACY PROTECTION

摘要

Disclosed is a method for implementing a software tool for use in USB flash disk privacy protection, comprising the following steps: 1. starting a process, detecting the presence at a computer USB interface of an accessory hardware device connection; 2. when a USB storage driver runs a function preparing to run the accessory hardware device, intercepting an operating system low-level interrupt for the running of the accessory hardware device, and performing an interrupt handling process; 3. acquiring a process running space for the interrupt handling process; 4. inserting an interception function for acquiring accessory hardware device information; 5. determining, on the basis of the accessory hardware device information acquired by the interrupt, if a storage device is what that is present, executing step 6 if yes, and executing step 8 if otherwise; 6. modifying an attribute of the storage device, the operating system identifying the storage device as a hard disk; 7. partitioning the USB flash disk identified as the hard disk, where a first partition is a common partition visible to all, while other partitions are matched to a privacy partition software and open when the computer has installed the privacy partition software; and, 8. ending the process.
