1. A system for removing steganography from a digital data, the system comprising:
a receiving device configured to receive digital data including at least one of image data and audio data; and
at least one processing device configured to access a steganography purifier model having at least a generator configured to: scale a magnitude of individual data elements of the digital data from a first value range to a second value range, downsample the scaled data elements to remove steganography data embedded in the digital data and produce a purified version of the digital data, upsample the purified version of the digital data by interpolating new data elements between one or more adjacent data elements to provide an upsampled purified version of the digital data, and scale the data elements of the upsampled purified version of the digital data from the second value range to the first value range to generate a purified output version of the received digital data.
