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.

Electronic device for encrypting biometric information and method for operating the same

Provided is a portable electronic device including, a biometric sensor; a touch sensing display; a wireless communication module including wireless communication circuitry; a processor operatively connected to the biometric sensor, the display, and the wireless communication module; and a memory operatively connected to the processor, wherein the memory stores instructions which, when executed, cause the processor to: control the wireless communication module to perform data communication for user authentication with an authentication server based on reception of biometric information of a user from the biometric sensor, based on verifying that the user is qualified to use the portable electronic device via the data communication with the authentication server, perform data communication for identity verification of the user with a verification server via the wireless communication module, receive, from the verification server via the wireless communication module, a uniform resource locator (URL) including a one-time token for accessing a verification result provided by the verification server, transmit the one-time token to a service server that provides an on-line service via the wireless communication module, and control the display to display a code including the one-time token on the display.
