The term “module” used in the present document includes a unit including one or more of hardware, software, or firmware, and may be interchangeably used with a term such as a unit, a logic, a logical block, a component, a circuit, and the like. The “module” may be an integrally constructed component or a minimum unit or one part thereof for performing one or more functions. The “module” may be mechanically or electrically implemented, and may include, for example, a dedicated processor, a CPU, circuitry, an Application-Specific Integrated Circuit (ASIC) chip, a Field-Programmable Gate Arrays (FPGAs), or a programmable-logic device, which is known or to be developed to perform certain operations.

At least one part of an apparatus (e.g., modules or functions thereof) or method (e.g., operations) according to various example embodiments may be implemented with an instruction stored in a computer-readable storage media (e.g., the memory 130). If the instruction is executed by one or more processors (e.g., the processor 120), the one or more processors may perform a function corresponding to the instruction. The computer-readable storage media may include a hard disk, a floppy disk, magnetic media (e.g., a magnetic tape), optical media (e.g., a Compact Disc-ROM (CD-ROM), a Digital Versatile Disc (DVD), magnetic-optic media (e.g., a floptical disk)), an internal memory, or the like. The instruction may include a code created by a compiler or a code executable by an interpreter.

According to various example embodiments, a recording medium may record a program for executing operations of receiving an access request for the electronic device from an external electronic device, activating the authentication module in response to the access request, transmitting, to the external electronic device, an authentication information request for the authentication module, receiving, from the external electronic device, authentication information corresponding to a user of the external electronic device in response to the authentication information request, performing authentication on the user on the basis of the authentication information by using the authentication module, and deactivating the authentication module if the authentication is complete.

According to various example embodiments, a recording medium may record a program for executing operations of connecting communication with a plurality of external devices, requesting the plurality of external devices for identification information, receiving the identification information from at least one of the plurality of external devices in response to the identification information request, and cancelling the request to at least one external device different from the at least one of the plurality of external devices on the basis of the reception.

The module or programming module according to various example embodiments may further include at least one or more elements among the aforementioned elements, or may omit some of them, or may further include additional other elements. Operations performed by a module, programming module, or other elements may be executed in a sequential, parallel, repetitive, or heuristic manner. In addition, some of the operations may be executed in a different order or may be omitted, or other operations may be added.

Various example embodiments have an advantage in that a convenience is improved on the basis of user authentication since the heterogeneous electronic devices 410 and 420 provide an authentication function through bio sensing.

As described above, an electronic device and an operating method thereof according to various example embodiments have an advantage in that a convenience is improved on the basis of user authentication since the heterogeneous electronic devices provide an authentication function through bio sensing.
