Manufacturing method of SD card having general data copyright protection function

Abstract

The invention discloses a manufacturing method of an SD card having a general data copyright protection function. The manufacturing method mainly comprises the steps that data files formed by mainly synthesizing a data SN, a terminal equipment SN, a user SN and an order ID, and HASH values 2 are extracted and stored into the SD card and a corresponding database of terminal equipment; the HASH values 2 on the SD card and the terminal equipment are compared, non-video and non-audio data and application procedures are decoded and decrypted after successful comparison, all the files are copied into the SD card, the SD card is successfully manufactured and can be normally used after the step S801 is performed, the step S701 and the step S702 both need to be performed each time when the SD card is replaced, unification among the card, the machine, an order, a user and the data is guaranteed, and legitimate interests of merchants and consumers are guaranteed.

Description

technical field [0001] The invention relates to the field of SD card production, in particular to the field of SD card design based on the mutual binding of user SN, terminal equipment SN, order ID and data SN, and the general data copyright protection function applied in non-CPRM environment. Background technique [0002] With the continuous development of the mobile Internet, the problem of copyright protection in the mobile Internet is becoming more and more serious, especially in the copyright protection in sales, the problem is very prominent. [0003] In the era when VCD / DVD is popular, due to the copyright protection of VCD / DVD, under the protection of CPRM, the copyright protection of genuine VCD / DVD is smoothly distributed on a large scale. [0004] At present, with the development of the mobile Internet, VCD / DVD and other disc-based media can no longer meet the development needs. Instead, flash memory cards such as SD cards and TF cards have become the main media f...

AI Technical Summary

Problems solved by technology

Although the original SD card and TF card are written into the CPRM system when they leave the factory, but because there are few application methods supporting CPRM at present, the SD card use environment is much more complicated than the equipment environment in the VCD / DVD period, and it is difficult to realize For large-scale applications, it is difficult to achieve the status of protecting SD cards just by protecting VCD / DVD

Therefore, at present, it is difficult for us to see SD card records issued with SD cards instead of VCD / DVD, and it is also difficult to see that SD cards can be used as the distribution medium of WINDOWS and other software, and it is even more difficult to see SD cards as media that cannot be run off the disk. Great apps that don't work off the SD card

[0005] However, SD card as a popular carrier, if it can be fully utilized to promote copyrighted materials, it will inevitably reproduce the popular myth of VCD / DVD
