Provided is a module and method for transmitting information using a wireless hidden signal, which is capable of transmitting important information data requiring extreme security using a wireless hidden signal, and allowing the important information to be detected and distinguished by only promised transmitting/receiving parties so that the possibility of the wireless hidden signal being discovered can be minimized and security can be enhanced. The module for transferring information using a wireless hidden signal includes: a hidden formatting unit configured to generate a transmission data frame structure based on data that needs to be wirelessly transmitted; a hidden encoding unit configured to encode the generated transmission data frame structure to generate and output a hidden encoded bit stream; and a hidden modulation unit configured to convert the output hidden encoded bit stream into a wireless signal in a wireless transmission format.
