Electronic device for enhancing security using feature of eyeball image and method for controlling same

A non-transitory computer-readable recording medium having recorded thereon instructions which, when executed by at least one processor, comprising processing circuitry, individually and/or collectively, of a wearable device, cause the wearable device to:

• detect a user’s wearing of the wearable device;
• based on the detection, acquire an eyeball image of the user wearing the wearable device using light output from at least one light-emitting diode of the wearable device, through at least one camera of the wearable device;
• determine whether the user is a legitimate user, based on position information of at least one glint corresponding to the at least one light-emitting diode and included in the acquired eyeball image;
• and
• perform an iris authentication for the user, based on the user being a legitimate user.

A method of operating a wearable device, comprising:

• detecting that the wearable device is worn by a user,
• based on the detection, obtaining an eye image of the user wearing the wearable device using light output from at least one light emitting diode of the wearable device via at least one camera of the wearable device, and
• based on position information of at least one glint, included in the obtained eye image and corresponding to the at least one light emitting diode, determining whether the user is a legitimate user, and
• based on the user being the legitimate user, performing an iris authentication for the user.
