Patent number: 11475114Abstract: A terminal for checking a security request level of a fingerprint verification request is provided. The terminal includes a fingerprint recognition sensor configured to acquire a fingerprint image; and a controller configured to check a security request level of a fingerprint verification request when the fingerprint verification request is received, to determine an verification level depending on the security request level, and to perform fingerprint verification in a manner corresponding to the verification level by using the fingerprint image. The controller controls the fingerprint recognition sensor to acquire a fingerprint image of a first level when the security request level is less than or equal to the security request level of a previous verification request that has been completed before the fingerprint verification request, and an elapsed time from the previous verification request is within a threshold time.Type: GrantFiled: June 4, 2018Date of Patent: October 18, 2022Assignee: HIDEEP INC.Inventors: Sein Lee, Youngho Cho, Seyeob Kim, Byung Duck Cho
