1. A method for providing a virtual code, the method comprising:
receiving, by a virtual code verifying device, the virtual code from a virtual code generating device, the virtual code being generated by combining a plurality of detailed codes according to a specific rule, the virtual code being a code generated in connection with a real code at a specific time;
extracting, by the virtual code verifying device, the plurality of detailed codes included in the virtual code; and
searching for, by the virtual code verifying device, the real code based on a correlation between the plurality of detailed codes,
wherein the plurality of detailed codes is changed per a time interval,
wherein the virtual code verifying device and the virtual code generating device include the same virtual code generation function,
wherein the virtual code generation function includes a plurality of detailed code generation functions for generating each of the plurality of detailed codes,
wherein the detailed code generation function applies a specific sorting rule of sorting M characters in an ascending order, and
wherein the M characters comprise at least one of an uppercase alphabet, a lowercase alphabet, a numeral, and a special character.
