Method and apparatus for key generation based on face recognition using cnn and rnn

A face recognition based key generation apparatus comprising:

• a key generation model formed of a convolutional neural network (CNN) and a recurrent neural network (RNN), receiving a facial image of a key owner and a personal identification number (PIN) of the key owner, as inputs at a desired key generation time, and generating a key;
• and
• a processor that controls the key generation model to be learned to generate a desired key having a consistent value by using sample facial images of a key owner and a PIN of the key owner as inputs.

A face recognition based key generation method comprising:

• learning a key generation model that is formed of a convolutional neural network (CNN) and a recurrent neural network (RNN) for outputting a consistent key value by using sample facial images of a key owner as inputs;
• and
• outputting the key by receiving a facial image of the key owner at a desired key generation time, by the key generation model.
