Abstract: An electronic device is provided. The electronic device includes a communication interface including circuitry, a memory, and a processor which, based on receiving ID information generated by performing a first encryption process on biometric information and password information generated by performing a second encryption process on the biometric information from an external electronic device through the communication interface, is configured to control the electronic device to: store the ID information and the password information in the memory. The processor, based on receiving first ID information and first password information from the external electronic device, is configured to control the electronic device to: acquire at least one candidate ID information from the memory based on the first ID information, compare password information corresponding to each of the acquired at least one candidate ID information with the first password information to identify one of the candidate ID information, and perform user authentication based on the identified candidate ID information and corresponding password information.

Abstract: An electronic device is provided. The electronic device includes a camera, a memory configured to store a model learned to determine whether a user performing authentication for a financial service is in a threat situation, and a processor configured to perform authentication for the financial service based on biometrics information of the user performing authentication for the financial service. The processor may acquire an image by photographing the user performing authentication through the camera, acquire information on whether the user performing authentication is in a threat situation from the learned model, with information acquired from the image as input of the learned model, and perform authentication for the financial service according to the acquired information. At least a part of the learned model is an artificial intelligent algorithm, which may be performed according to at least one of machine learning, neural network, or deep learning algorithm.

Abstract: A data protection method and apparatus that can protect data through encryption using a Boolean function is provided. The data protection method includes applying an inverse affine transformation to data to be encrypted using a Boolean function; applying round operations of an Advanced Encryption Standard (AES) cryptographic algorithm to the inverse-affine transformed data; and producing ciphertext data by applying an affine transformation to the result of the round operations.
