Abstract
A method for learning an obfuscation network used for concealing original data is provided. The method includes steps of: a learning device instructing the obfuscation network to obfuscate inputted training data, inputting the obfuscated training data into a learning network, and allowing the learning network to apply a network operation to the obfuscated training data and thus to generate 1-st characteristic information, and allowing the learning network to apply a network operation to the inputted training data and thus to generate 2-nd characteristic information, and learning the obfuscation network such that an error is minimized, calculated by referring to part of an error acquired by referring to the 1-st and the 2-nd characteristic information, and an error acquired by referring to a task specific output and its corresponding ground truth, and such that an error is maximized, calculated by referring to the training data and the obfuscated training data.
