Abstract
Embodiments of the present invention provide a method, program, and apparatus that may identify a device by using a virtual code generated based on a unique value of a chip inside a device without a separate procedure for identifying the device. Furthermore, embodiments of the present invention provide a method, program, and apparatus that may generate a virtual code, which is not matched with any other code, whenever a code for identifying a device is requested. Moreover, embodiments of the present invention provide a method, program, and apparatus for identifying a device that may add and use only an algorithm without changing a conventional process.
Claims10
A method for identifying a device by using a chip unique value-based virtual code, the method comprising:
- receiving, by a virtual code verification means comprising a computer which is hardware, a virtual code generated by a virtual code generation means comprising a computer which is hardware;
- extracting, by the virtual code verification means, a plurality of detailed codes included in the virtual code;
- and
- searching, by the virtual code verification means, for an actual code based on the plurality of detailed codes,
- wherein the virtual code is generated based on a unique value assigned in advance to a chip inside the virtual code generation means, and is generated by combining the plurality of detailed codes,
- wherein the plurality of detailed codes have a correlation for searching for the actual code and are changed for each unit count,
- wherein the unit count is set to a specific time interval and is changed as the time interval elapses,
- wherein the virtual code verification means includes a search algorithm,
- wherein the plurality of detailed codes include a first code and a second code, and
- wherein the search algorithm passes a waypoint corresponding to the first code, performs a calculation based on a correlation between the first code and the second code from the waypoint, and searches for the actual code.
