Abstract
An apparatus and method for authenticating digital data is described. The method comprises generating the digital data with a radio device that operates on a narrowband channel and associating metadata to the digital data, the metadata being unique to the digital data. Further, a predefined function is applied to both the digital data and the associated metadata to generate an authentication key, and the authentication key is transmitted for storage at a remote server via the narrowband channel. The digital data is then authenticated using the stored authentication key.
