Abstract: An electronic device may comprise: an image sensor, an image pre-processor comprising circuitry, memory storing instructions, and at least one processor comprising processing circuitry. The instructions, when executed by at least one processor, individually and/or collectively, may cause the electronic device to: obtain raw data including biometric data using the image sensor. The instructions, when executed by at least one processor, individually and/or collectively, may cause the electronic device to store, in a first buffer, the raw data as first image data. The instructions, when executed by at least one processor, individually and/or collectively, may cause the electronic device to store, in a second buffer, second image data generated by applying a change operation to the raw data using the image pre-processor. The instructions, when executed by at least one processor, individually and/or collectively, may cause the electronic device to forward the first image data stored in the first buffer to a first application included in a secure area and apply a first algorithm for biometric authentication to the first image data. The instructions, when executed by at least one processor, individually and/or collectively, may cause the electronic device to forward the second image data stored in the second buffer to a second application included in a non-secure area and apply a second algorithm different from the first algorithm to the second image data. Other various embodiments are also available.

Abstract: An electronic device according to various embodiments of the present disclosure includes: at least one sensor; a communication circuit; at least one processor operably coupled with the at least one sensor and the communication circuit; and at least one memory operably coupled with the at least one processor, wherein the memory may store instructions which, when executed, cause the processor to: receive a request for authenticating a user of the electronic device using a designated authentication method; identify whether a device selected as a reference device is a first device among the first device and a second device which are included in the at least one sensor and the communication circuit, and are capable of generating authentication data required for using the designated authentication method to authenticate the user; generate data, when first authentication data for authenticating the user is acquired from the first device, indicating a first time point at which the processor acquired the first authentication data; generate data, when second authentication data for authenticating the user is acquired from the second device, indicating a second time point at which the processor acquired the second authentication data; confirm, based on the first data indicating the first time point and the second data indicating the second time point, whether the second time point is within a threshold time range based on the first time point; and authenticate the user using the first authentication data and the second authentication data based on whether the second time point is within the threshold time range based on the first time point.
