Source code is exactly the basic of company (particularly some software companys), is the achievement of employee's dint of hard work work; If the technology source code, to outward leakage, will bring massive losses to company.
Summary of the invention
The technical matters that actual needs of the present invention solves is: for deficiency of the prior art, a kind of method that prevents the source code copy by Dynamic Recognition ID is provided, by current hardware device ID and given hardware device ID are compared, if it is not identical, delete the source code in current device, thereby realize preventing that source code is by illegal copies, reduced source code and transplanted the risk of illegal use by other people.
Technical matters solved by the invention can realize by the following technical solutions:
A kind of method that prevents the source code copy by Dynamic Recognition ID, it is characterized in that: described method comprises the steps:
1) model static link library engineering, and create the detection thread function for detection of hardware device ID in the static link library engineering, described detection thread function can realize when hardware device ID does not mate, and deletes the function of the source code in hardware device;
2) static state or global variable are set and whether detect described detection thread function in operation, the initialize of described static state or global variable is false;
3) degree of coupling in source code is low and public function that can carry out is transplanted in static link library, then associated with static variable at these public functions; When the value of static variable is false, the start detection thread function is true by the static variable assignment simultaneously, to realize thread monitoring function, only moves once;
4) finally compile the static link library engineering and generate the LIB library file, and the LIB library file is added in source code, statement encapsulation function, delete and encapsulate the original part that realizes of function, and the direct compilation source code realizes the copy-proof function of source code.
Further, but the identification id with uniqueness of described hardware device ID for being formed by CPU sequence number, hard disk sequence number, MAC Address of Network Card, the domain-name information of equipment.
Compared with prior art, beneficial effect of the present invention is as follows:
1. disguised high, by create the detection thread function for detection of hardware device ID in the static link library engineering, make the stranger can't wipe easily feel.
2. security is good, but the identification id with uniqueness that hardware device ID forms for CPU sequence number, hard disk sequence number, MAC Address of Network Card, domain-name information by equipment, the illegal copies that can effectively prevent.
The accompanying drawing explanation
Fig. 1 is the logical diagram that prevents the method for source code copy of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the present invention.
