## Abstract

An electronic device is provided. The electronic device includes a display configured to display information, an input device configured to receive a user input, an image sensor, a processor electrically connected with the display, the input device, and the image sensor, and a non-transitory computer readable storage medium electrically connected with the processor that stores instructions that cause the processor to control the display to display first-level information as a locking mode is partially released when partial authentication passes based on bio-information acquired through the image sensor in a state in which the electronic device is in the locking mode, and control the display to display second-level information having a security level higher than a security level of the first-level information as the locking mode is fully released when full authentication passes based on a user input made through the input device.

## Claims

### Claim 1

(canceled)

### Claim 2

An electronic device comprising:
a touchscreen display;
an image sensor; and
a processor electrically connected with the touchscreen display and the image sensor, the processor configured to:

perform a first authentication based on an image of a user obtained via the image sensor while the notification is displayed as at least partially overlapped with the lock screen,
based on a success of the first authentication, display first additional information related to the specified event via the touchscreen display as at least partially overlapped with the lock screen, the first additional information previously hidden from view before the first authentication,
perform a second authentication based on a touch input obtained via the touchscreen display, and
based on a success of the second authentication, display second additional information related to the specified event via the touchscreen display, the second additional information previously hidden from view before the second authentication.

### Claim 3 (depends on 2)

The electronic device of claim 2, wherein the image includes a face image, and wherein the processor is further configured to perform the first authentication based on face information corresponding to the face image.

### Claim 4 (depends on 2)

The electronic device of claim 2, wherein the image includes an iris image, and wherein the processor is further configured to perform the first authentication based on iris information corresponding to the iris image.

### Claim 5 (depends on 2)
