Patent Description:
Recently, electronic devices have been developed, including various functions, for example, capturing of a picture or video, Internet communication, and the like, in addition to a simple call function. As the electronic devices encompass various functions, security of personal information is becoming more important. In particular, the personal information security is very important for an electronic device that includes functions that may cause significantly serious damage when they are illegally used by a stranger such as Internet financial services and the like. In this way, as importance of security of electronic devices increases, security functions of various methods are equipped to restrict use of the electronic devices by other users.

For the security, biological features are used to identify persons, and studies on the security technologies using various pieces of body information such as a fingerprint, a voice, a retina, a face, and an iris are being made. Among the various pieces of body information, the patterns of fingerprints of individuals are different, and in particular, because the danger of imitating fingerprints is low and the fingerprints rarely change during the lifetime, a security technology is getting the spotlight. <CIT> (<NUM>-<NUM>-<NUM>) discloses am method indicating to the user the parts (nodes) of the finger which are already analyzed during enrollment or matching.

The regions acquired are indicated on a synthetic fingerprint image (to avoid displaying the real fingerprint).

The minutiae or pictures are sent encrypted from the sensor to the matcher (secure enclave processor), which only delivers a node matching result.

The user is guided to present the next needed node with an indicator on the synthetic fingerprint. Additional nodes captured are indicated to the user.

<CIT> (<NUM>-<NUM>-<NUM>) discloses the reconstruction of a composite image aggregating the best quality images in a composite fingerprint image.

The user is guided to move in a determined manner using either text, and/or pictorial instructions, such as in the form of an arrow or other icon or pictograph, directing the user to improve the composite image by moving or pressing his finger.

The electronic device displays an execution screen that is irrelevant to a fingerprint of the user that is registered when the fingerprint of the user is registered, consumes much time in registering a fingerprint because fingerprints may not be recognized frequently if a location of a finger is wrongly input when the fingerprint is registered, and cannot identify whether the fingerprint is properly registered or how clearly the actual fingerprint of the user is registered.

Furthermore, when the electronic device fails to recognize a fingerprint, guide information for registration of a fingerprint, other than guide information that informs that the fingerprint cannot be recognized, is not provided.

To address the above-discussed deficiencies, it is a primary object to provide, for example, an electronic device that can display information on a fingerprint registration progress situation in correspondence to a plurality of sequentially input fingerprints, can determine whether a fingerprint of the user is to be registered according to the information on the fingerprint registration progress situation, and can register the fingerprint of the user by using at least some of the plurality of fingerprints, and a method of registering a fingerprint in an electronic device.

<CIT> discloses a fingerprint sensing system. Additionally, reference is made here to <CIT> and ISBN: <NUM>-<NUM>-<NUM>-<NUM>-<NUM>. Moreover, <CIT> is acknowledged here to constitute the closest prior art, relative to which the present disclosure is distinguished by features defined in the characterizing portions of appended independent device and method claims.

The above and other aspects, features, and advantages of the present disclosure will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: For a more complete understanding of the present disclosure and its advantages, reference is now made to the following description taken in conjunction with the accompanying drawings, in which like reference numerals represent like parts:.

Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably arranged device. Hereinafter, the present disclosure will be described with reference to the accompanying drawings. The present disclosure may have various embodiments, and modifications and changes may be made therein. Therefore, the present disclosure will be described in conjunction with particular embodiments shown in the accompanying drawings. However, it should be understood that there is no intent to limit the present disclosure to the particular forms disclosed herein; rather, the present disclosure should be construed to cover various modifications, equivalents, and/or alternatives of embodiments of the present disclosure. In describing the drawings, similar reference numerals may be used to designate similar constituent elements.

In the present disclosure, the expression "include" or "may include" refers to existence of a corresponding function, operation, or element, and does not limit one or more additional functions, operations, or elements. In the present disclosure, the terms such as "include" and/or "have" may be construed to denote a certain characteristic, number, step, operation, constituent element, element or a combination thereof, but may not be construed to exclude the existence of or a possibility of addition of one or more other characteristics, numbers, steps, operations, constituent elements, elements or combinations thereof.

In the present disclosure, the expression "A or B", "at least one of A or/and B", or "one or more of A or/and B" may include all possible combinations of the items listed. For example, the expression "A or B", "at least one of A and B", or "at least one of A or B" may include (<NUM>) at least one A, (<NUM>) at least one B, or (<NUM>) both at least one A and at least one B.

The expression "a first", "a second", "the first", or "the second" used in various embodiments of the present disclosure may modify various components regardless of the order and/or the importance but does not limit the corresponding components. The above expressions are used merely for the purpose of distinguishing an element from the other elements. For example, a first user device and a second user device indicate different user devices although both of them are user devices. For example, a first element may be termed a second element, and similarly, a second element may be termed a first element without departing from the scope of the present disclosure.

When it is mentioned that one element (e.g., a first element) is "(operatively or communicatively) coupled with/to or connected to" another element (e.g., a second element), it should be construed that the one element is directly connected to the another element or the one element is indirectly connected to the another element via yet another element (e.g., a third element). In contrast, it may be understood that when an element (e.g., first element) is referred to as being "directly connected," or "directly coupled" to another element (second element), there are no element (e.g., third element) interposed between them.

As used herein, the expression "configured to" may be interchangeably used with the expression "suitable for", "having the capability to", "designed to", "adapted to", "made to", or "capable of". The term "configured to" may not necessarily imply "specifically designed to" in hardware. Alternatively, in some situations, the expression "device configured to" may mean that the device, together with other devices or components, "is able to". For example, the phrase "processor adapted (or configured) to perform A, B, and C" may mean a dedicated processor (e.g. embedded processor) only for performing the corresponding operations or a generic-purpose processor (e.g., central processing unit (CPU) or application processor (AP)) that can perform the corresponding operations by executing one or more software programs stored in a memory device.

The terms used in the present disclosure are only used to describe specific embodiments, and are not intended to limit the present disclosure. As used herein, singular forms may include plural forms as well unless the context clearly indicates otherwise.

Unless defined otherwise, all terms used herein, including technical and scientific terms, have the same meaning as those commonly understood by a person skilled in the art to which the present disclosure pertains. Such terms as those defined in a generally used dictionary may be interpreted to have the meanings equal to the contextual meanings in the relevant field of art, and are not to be interpreted to have ideal or excessively formal meanings unless clearly defined in the present disclosure. In some cases, even the term defined in the present disclosure should not be interpreted to exclude embodiments of the present disclosure.

<FIG> is a flowchart illustrating an operation procedure of an electronic device according to various embodiments of the present disclosure. <FIG> is a diagram illustrating fingerprint recognition in an electronic device according to various embodiments of the present disclosure.

Referring to <FIG> and <FIG>, according to an embodiment of the present disclosure, in operation <NUM>, if the user inputs a fingerprint in one area of an electronic device, the electronic device (for example, the electronic device <NUM> of <FIG>) may receive a fingerprint of the user that is detected through at least one sensor located in the one area.

According to various embodiments of the present disclosure, in the following operations, the electronic device may temporarily store a detected fingerprint, that is, an input fingerprint, and may process recognition of a fingerprint for the temporarily stored fingerprint.

In operation <NUM>, as illustrated in <FIG>, the electronic device may binarize <NUM> the extracted directional component information, and may detect a fingerprint corresponding to the directional component information, that is, may recognize the input fingerprint by classifying <NUM> the binarized fingerprint shape.

In operation <NUM>, the electronic device may generate a fingerprint image corresponding to the recognized fingerprint and information on the fingerprint registration progress situation. According to various embodiments of the present disclosure, the electronic device may synthesize at least one previously generated fingerprint image and the currently generated image so that the recognized fingerprint may be viewed more clearly whenever the user inputs a fingerprint. The information on the fingerprint registration progress situation may be displayed by using a fingerprint image corresponding to the plurality of input fingerprints, that is, a fingerprint image of the actual user, and may include at least one of display form information of the plurality of fingerprints sequentially input (for example, at least one of a user fingerprint image, a gauge bar and a message), display attribute information (for example, at least one of shape, color, brightness, light and shade, contrast, size, width, height, area, density, margin, and transparency), and fingerprint registration progress rate information.

Referring to <FIG>, the electronic device (for example, the electronic device <NUM> of <FIG>) according to various embodiments of the present disclosure may detect a fingerprint shape of the central area as a feature point <NUM> in the fingerprint input first, for example, as illustrated in <FIG>, as the user inputs <NUM> a fingerprint. The electronic device may detect the shape of the central area in the next input fingerprint as a feature point <NUM>, and may identify a location of the feature point <NUM> that is detected before with respect to the detected feature point <NUM>. In the identification result, when the location of the previously detected feature point <NUM> is located in a lower-left area (for example, a fourth area) as illustrated in <FIG>, the electronic device may further recognize a right fingerprint area of a finger of the actual user and may guide the fingerprint input direction to the left side <NUM> to further recognize a left fingerprint area.

According to various embodiments of the present disclosure of <FIG>, the electronic device may synthesize all the fingerprint images corresponding to the plurality of fingerprints input according to the guided fingerprint input direction to generate a fingerprint image that is to be finally registered. The fingerprint image that is to be finally registered is a fingerprint image having a wide area, and because a failure probability of a fingerprint input may be decreased even if the user inputs a fingerprint in any direction when the electronic device is driven or a function of an application is executed through the following recognition of a fingerprint, a fingerprint recognition rate can be increased. <FIG> and <FIG> are diagrams illustrating a fingerprint registration screen of an electronic device according to various embodiments of the present disclosure.

Referring to <FIG>, according to various embodiments of the present disclosure, the electronic device (for example, the electronic device <NUM> of <FIG>) may identify feature points in a fingerprint input first as the user inputs a fingerprint, and may generate a guide message for the next fingerprint input based on the identified feature points. The electronic device may store and display a fingerprint image <NUM> for a fingerprint input to the execution screen of the display unit, and may display a guide message <NUM> (for example, "Input right area") that guides the next fingerprint input or output the guide message <NUM> as a sound source.

The electronic device may identify feature points in the input fingerprint, and may generate a guide message <NUM> that guides the next fingerprint input based on the identified feature point and display the generated guide message <NUM>. According to various embodiments of the present disclosure, the electronic device may compare the identified feature points and the previous feature points to set a fingerprint input direction, and may generate and display a guide message <NUM> (for example, "Input left area") that guides the next fingerprint input according to the set fingerprint input direction.

The electronic device may register a fingerprint image <NUM> that is to be registered finally, and may display a guide message <NUM> (for example, "Fingerprint is completely registered) for guiding completion of registration of a fingerprint. The fingerprint image that is to be finally registered is a fingerprint image having a wide area, and because a failure probability of a fingerprint input may be decreased even if the user inputs a fingerprint in any direction when the electronic device is driven or a function of an application is executed through the following recognition of a fingerprint, a fingerprint recognition rate can be increased.

According to various embodiments of the present disclosure, the electronic device (for example, the electronic device <NUM> of <FIG>) may guide a fingerprint input direction to the user as described above when a fingerprint of the user is not input at a central location of at least one sensor area included in the electronic device and the recognition of a fingerprint fails.

According to various embodiments of the present disclosure, if a margin (empty space) is present in an area that displays a fingerprint image corresponding to the fingerprint of the user, the electronic device may identify an area of a fingerprint that is input through the margin.
