Abstract
An electronic device encrypting biometric information includes memory for storing instructions and a processor. The instructions may be configured to, when executed by the processor, cause the electronic device to obtain a transformation matrix that maps a first feature value related to first biometric information to a first codeword, generate a third feature value by applying the transformation matrix to a second feature value related to second biometric information, compare a cosine similarity between a second codeword most similar to the third feature value and the third feature value with a threshold, map the second feature value to the second codeword based on the cosine similarity being greater than the threshold, and generate a hashed second codeword based on the second codeword, and transmit or store the hashed second codeword.
