Abstract: A method by an electronic device may include detecting a bio-signal related to a user of the electronic device from at least one biometric sensor of the electronic device, and switching a mode or controlling a volume of a communication session between the electronic device and another electronic device based on at least part of the bio-signal. Other embodiments are also possible.

Abstract: Disclosed is a method and apparatus for executing an application or a service. The method includes determining a security level associated with an application or a service of which execution is requested, changing at least part of a graphic object based on the determined security level, and displaying the changed graphic object, obtaining an input through a body of rotation that is included in the electronic device, and executing the application or the service when the input corresponds to security information associated with the application or the service.
