Description

Electronic device having a fingerprint sensor and method for updating fingerprint information thereof

Various embodiments of the present disclosure disclose an electronic device having a fingerprint sensor and a method of dynamically updating fingerprint information in the electronic device.

As the functions of the electronic device are diversified, for example, a multimedia device (multimedia player) having complex functions such as taking a picture or a video, playing a music or a video file, playing a game, receiving a broadcast, or a call function. ) is implemented in the form Such an electronic device may include a display, and may display screens related to functions based on the display.

As various functions can be executed in the electronic device, information related to a user's privacy and/or information requiring security may be stored in the electronic device. For example, the electronic device stores not only information such as contact information, call history, or messages, but also various privacy information (or personal information) such as user location information, memo information, photos, or financial transaction information. can be Therefore, while the electronic device can perform various functions by the complex function, since it stores the user's privacy information, it may be vulnerable to privacy exposure, personal information leakage, or security.

Recently, electronic devices provide various security functions to protect user's privacy information or privacy, and a user's own authentication means is being developed for each electronic device. Among these security functions, a fingerprint authentication method may be included. For example, the fingerprint authentication method is easy to implement in an electronic device of a small form factor, and has advantages of relatively high accuracy and high security, and thus has been widely applied as an authentication method of an electronic device.

The electronic device may recognize a fingerprint using a fingerprint sensor or fingerprint reader. A fingerprint sensor included in an electronic device is implemented as a small fingerprint sensor that may be smaller than a user's fingerprint in order to reduce an effective surface area. Accordingly, in a method of obtaining optimal fingerprint recognition performance with a small fingerprint sensor, a user may register and use multiple pieces of fingerprint information of the same finger. For example, a user may input (eg, touch) a finger to the fingerprint sensor several times during fingerprint registration, and the electronic device may combine a plurality of fingerprint images (or partial images or fragment images) according to the repeated input. One fingerprint information can be registered. For example, the user may duplicate the same finger as a separate fingerprint to improve the recognition rate. However, even if the same finger is repeatedly registered, the recognition rate may be low when a large area of the fingerprint is not registered. Also, an area of a memory for storing fingerprint information in the electronic device may be limited, and when multiple fingerprints are registered by the same finger, fingerprints of various fingers cannot be registered.

Various embodiments provide a method and apparatus capable of dynamically updating fingerprint information previously registered in a memory in an electronic device having a fingerprint sensor.

However, it should be understood that the detailed description and specific embodiments, such as preferred embodiments of the present disclosure, are given by way of example only, since various changes and modifications within the spirit and scope of the present disclosure may be clearly understood by those skilled in the art.

According to an electronic device and an operating method thereof according to various embodiments of the present disclosure, by automatically analyzing at least two pieces of fingerprint information previously registered by a user in the electronic device at a specified point in time, and integrating the duplicated fingerprint information into one fingerprint information, the existing fingerprint information can be dynamically updated. According to an embodiment, the fingerprint recognition rate may be improved by integrating similar fingerprint information into one fingerprint based on the similarity between fingerprint information previously registered in different regions of the memory in the electronic device. According to an embodiment, the electronic device may secure an additional area of the memory for fingerprint information through integrated management of duplicate fingerprint information registered in different areas of the memory. For example, the electronic device may have a limited memory area (eg, a slot) for fingerprint information. According to an embodiment, for the purpose of increasing the recognition rate, the electronic device deletes and integrates unnecessary fingerprints according to repeated registration of duplicate fingerprints to store more fingerprint images in one area (eg, a slot) to improve the fingerprint recognition rate. Also, it may be provided to register new fingerprint information through an additionally secured empty slot.
