Abstract

The invention provides a program signature and upgrade error recovery method based on a universal serial bus (USB) flash disk carrier. The program signature method comprises the following steps: reading the inherent identification ID of the current USB flash disk and the original inherent identification ID of a hidden storage partition by a program, and comparing the identification IDs; if the identification IDs are same, continuing to read a signature sequence and judging whether the signature sequence is correct; if the signature sequence is correct, executing the flow after the program signature; and if the signature sequence is incorrect, ending the program operation. The upgrade error recovery method comprises the following steps: storing an original program in the hidden storing partition of the USB flash disk carrier; and if the upgraded program can not operate normally, writing the original program in the hidden storing partition into a program storing partition.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a program signature and upgrade error recovery method based on a U disk carrier. Background technique [0002] With the widespread use of U disks, many applications start to use U disks as carriers. Although the application mode using the U disk as the carrier can facilitate the use of the application program, due to the reproducibility of the data in the U disk, the uniqueness of the product authorization cannot be guaranteed. Even if the manufacturer can control the authorization of the product through the authorization file, and can ensure that the program cannot run without authorization, it cannot restrict the application of the same authorization file to multiple programs. As long as the correct product authorization file is obtained, it can be used on any carrier. Use the product on the Internet, so there will be problems with the same product being used by multiple ...
