A method for training an obfuscation network for obfuscating data is provided. The method includes steps of: a learning device (a) (i) inputting training data into an obfuscation network to obfuscate the training data and generate obfuscated training data, and (ii) inputting the obfuscated training data into a compression network to generate binary training data and generate compression adaptive obfuscated training data; (b) inputting the compression adaptive obfuscated training data into a learning network to apply learning operation and generate first characteristic information and inputting the training data into the learning network to generate second characteristic information and (c) training the obfuscation network such that first errors, calculated using the first and the second characteristic information, are minimized and such that second errors, calculated using (1) modified training data or modified obfuscated training data and (2) the obfuscated training data or the compression adaptive obfuscated training data, are maximized.
