Embodiment Construction

[0047] The present invention provides a method and system for preventing software copying. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0048] Before describing the present invention, it is necessary to explain how criminals realize machine copy board cloning at present: obtain the machine at different stages such as the early prototype stage, factory production stage or finished product market sales stage; for hardware, use its direct visibility to pass The circuit copy board can realize hardware cloning; for the software, it is stored in the FLASH, due to the general requirements of the software upgrade function and cost considerations, these FLASH can be read and written repeatedly, use the stor...

Abstract

The invention discloses a method and a system preventing software from copying. The method comprises the following steps: A, the software is started initially; B, a physical identification code and FLASH storage identification code reading module is invoked for reading a physical identification code Ma and a FLASH storage code Mb; C, whether the Ma is equal to the Mb or not is judged, if equal, a step E is entered, if not, a step D is entered; D, the trial number of an illegal software is read and added by one, and then the result is stored to the FLASH; and E, the start of the software is completed. Through the invention, an authorized data base is introduced to uniformly manage the authorized information, any unauthorized machine is the illegal software, and the authorized process is written in a general bar code in a hidden manner. The machine software can be subject to the simple and effective authorized management during the prototype sending stage, factory large-scale production stage, and after-sales repair stage without adding the economical and process cost.

Description

technical field [0001] The invention relates to the field of preventing software copying, in particular to a method and system for preventing software copying. Background technique [0002] At present, the set-top box software is basically stored in FLASH. How to prevent criminals from reading the software code in FLASH to clone the machine at a relatively low cost during the process of prototype function confirmation, factory production, and finished product sales process? The production of each set-top box Businesses are always looking for better solutions. [0003] There are two main methods to prevent software copying. The first technical steps are as follows: [0004] A. Utilize the identification code on the hardware that can be used as the unique identification of the set-top box, such as the CPU serial number, additional hardware encryption chip, etc., and store the unique identification code used in each set-top box in the machine FLASH when the set-top box...
