Electronic device for processing plurality of pieces of information, and operating method therefor

A method of operating an electronic device, the method comprising:

• receiving a plurality of pieces of first contact information from an external device via at least one communication circuit of the electronic device;
• receiving a plurality of pieces of second contact information stored in a subscriber identification module (SIM) card of the electronic device via an interface of the electronic device;
• based on the plurality of pieces of first contact information and the plurality of pieces of second contact information, acquiring a plurality of pieces of third contact information, wherein the plurality of pieces of third contact information comprise at least one piece of contact information acquired based on contact information comprising identical data among the plurality of pieces of first contact information and the plurality of pieces of second contact information;
• identifying a plurality of pieces of tag information corresponding to the plurality of pieces of third contact information, wherein the plurality of pieces of tag information indicate whether each of a plurality of parameters associated with the plurality of pieces of third contact information has a plurality of data;
• identifying an input for selecting a first parameter from among the plurality of parameters;
• identifying, among the plurality of pieces of tag information, at least one piece of first tag information indicating that the first parameter has a plurality of data;
• acquiring a plurality of pieces of fifth contact information, based on at least one piece of fourth contact information corresponding to the at least one piece of first tag information from among the plurality of pieces of third contact information;
• and
• providing contact information remaining after excluding the at least one piece of fourth contact information from among the plurality of pieces of third contact information, and the plurality of pieces of fifth contact information.

One or more non-transitory computer-readable storage media storing computer-executable instructions that, when executed by at least one processor of an electronic device, cause the electronic device to perform operations, the operations comprising:

• receiving a plurality of pieces of first contact information from an external device via at least one communication circuit of the electronic device;
• receiving a plurality of pieces of second contact information stored in a subscriber identification module (SIM) card of the electronic device via an interface of the electronic device;
• based on the plurality of pieces of first contact information and the plurality of pieces of second contact information, acquiring a plurality of pieces of third contact information, wherein the plurality of pieces of third contact information comprise at least one piece of contact information acquired based on contact information comprising identical data among the plurality of pieces of first contact information and the plurality of pieces of second contact information;
• identifying a plurality of pieces of tag information corresponding to the plurality of pieces of third contact information, wherein the plurality of pieces of tag information indicate whether each of a plurality of parameters associated with the plurality of pieces of third contact information has a plurality of data;
• identifying an input for selecting a first parameter from among the plurality of parameters;
• identifying, among the plurality of pieces of tag information, at least one piece of first tag information indicating that the first parameter has a plurality of data;
• acquiring a plurality of pieces of fifth contact information, based on at least one piece of fourth contact information corresponding to the at least one piece of first tag information from among the plurality of pieces of third contact information;
• and
• providing contact information remaining after excluding the at least one piece of fourth contact information from among the plurality of pieces of third contact information, and the plurality of pieces of fifth contact information.
