FIG. 1 is a diagram illustrating a wearable device 100 that performs various functions through vein authentication, according to an exemplary embodiment.

The wearable device 100 may include a sensor 110 and a display unit 120 (e.g., display). The sensor 110 may perform a variety of functions such as capturing a vein image of a user or sensing a body temperature of the user. The display unit 120 may display at least one of an image, an icon, a clock, a video, etc.

The wearable device 100 may capture an image of the veins of the user to acquire the vein image. The wearable device 100 may capture the vein image in response to a predetermined situation occurring. For example, the wearable device 100 may sense a particular situation, such as a user putting on or taking off the wearable device 100, a user's performing a particular operation, a specific function being executed, or a particular application being executed, etc.

According to an exemplary embodiment, the wearable device 100 may capture the vein image when the user wears the wearable device 100. For example, the wearable device 100 may determine whether the user is currently wearing the wearable device 100. Further, the wearable device 100 may generate an event at the time when the user wears the wearable device 100. An event may refer to a predetermined situation that arises in which the wearable device responds by performing a predetermined action. For example, when the wearable device 100 determines that the user is currently wearing the device, the wearable device 100 generates an event and the wearable device 100 may capture the vein image. According to an exemplary embodiment, the wearable device 100 may determine through various sensors whether the user wears the wearable device 100. Then, the sensor may generate the event at the time when the user wears the wearable device 100.

In another exemplary embodiment, the wearable device 100 may capture the vein image when a function or a program that requires a user's authority is selected. For example, the wearable device 100 may generate an event at the time when a particular function or program is executed. When the event is generated, the wearable device 100 may capture the vein image. The function or the program that requires the user's authority may be preset by the user. In addition, a specific function or a specific program may request the user's authority. The executing of the function may be the wearable device 100 processing data, changing contents displayed on the display unit 120, or changing a plurality of pieces of set data. The program may a music player, a video player, a game, or another application installed on the wearable device 100.

According to an exemplary embodiment, the wearable device 100 may perform vein authentication by comparing the captured vein image with a registered vein image stored in memory or stored in an external server. The performing of the vein authentication may include determining whether any of the registered vein images matches the captured vein image.

According to an exemplary embodiment, when a plurality of registered vein images are provided, the wearable device 100 may sequentially compare the captured vein image with each of the registered vein images to select the registered vein image that matches the captured vein image. The matching of the captured vein image to the registered vein image may represent that the captured vein image matches the registered vein image in a set ratio or more by comparing the captured vein image with the registered vein image. In other words, there may be an error value attached to the matching of the captured vein image to the registered vein image, and when the error is a set critical value or less, the wearable device 100 may determine that the captured vein image matches the registered vein image.

According to an exemplary embodiment, the wearable device 100 may execute the function or the application without a separate user input by using data registered with respect to an identified user. Therefore, when a function or a program that requires user authentication is selected, the wearable device 100 may receive no separate input from the user and may automatically capture the vein image of the user to perform the user authentication. In other words, when the user has authority to use the function or the program, i.e., the user has a matching vein structure, the selected function or the selected program may be automatically executed without any input from the user. On the other hand, when the user has no authority to use the function or the program, i.e., the user does not have a matching vein structure, the selected function or the selected program may not be executed.

According to an exemplary embodiment, the wearable device 100 may execute various functions by using authentication. For example, the wearable device 100 may provide a music list according to music preferred by an authenticated user. The wearable device 100 may provide an advertisement or information in which the authenticated user is interested. The wearable device 100 may update a setting thereof according to the authenticated user. The wearable device 100 may provide a contact list of the authenticated user. The wearable device 100 may perform automatic login to an SNS accessed by the user. The wearable device 100 may be configured to only transmit data when the authenticated user has authority to transmit data. The wearable device 100 may attempt to connect to other devices by using information registered by the authenticated user. The wearable device 100 may attempt payment with a credit card by using information registered by the authenticated user. Functions provided by the wearable device 100 to the user will be described in detail below with reference to the drawings.

FIG. 2 is a block diagram of a wearable device 100 according to an exemplary embodiment. Referring to FIG. 2, the wearable device 100 may include a sensor 110 and a processor 140. According to an exemplary embodiment, the wearable device may include a controller that may include the processor 140.

The sensor 110 may capture a vein image. The sensor 110 may include a light source and a camera. The light source may emit an infrared ray, etc., and the camera may capture the vein image. While the infrared ray is emitted from the light source, the camera may capture an image of the back of user's hand, or another part of the body, to acquire the vein image. Since a portion in which a vein is disposed has high infrared reflectivity compared to other portions of the back of hand, the camera may capture a reflected infrared ray to capture the vein image.

According to an exemplary embodiment, the sensor 110 may capture an image of biological information capable of identifying the user. The identifying the user may include determining who is the user currently wearing the wearable device 100, or who is the user from among a plurality of registered users, which is wearing the wearable device 100. For example, the sensor 110 may capture an image of biological information on a user's vein, iris, or finger, etc. As another example, the sensor 110 may capture vein images of both the user's hands. As yet another example, the sensor 110 may capture vein images of the back of the user's hand and the palm of the user's hand. According to an exemplary embodiment, the sensor 110 may capture iris images of both of a user's eyes.

In response to a function or an application, which requires authentication, being selected, the processor 140 may control the sensor 110 to capture the vein image of the user wearing the wearable device 100. The selecting the function or the application may include a user selecting the function or the application by using an input unit (e.g., inputter) in order to execute the function or the application.

The processor 140 may then identify the user by comparing the captured vein image with a registered vein image from among a plurality of registered vein images. The processor 140 may identify the user currently wearing the wearable device 100. The identifying of the user may include determining any user who wears the wearable device 100 from among a plurality of users. In other words, the identifying of the user may include determining a registered vein image from among a plurality of registered vein images, which matches the vein image of the user currently wearing the wearable device 100. The comparing of the vein images may represent comparing shapes, structures, and/or thicknesses of veins included in the captured vein image and the registered vein images.

According to an exemplary embodiment, the processor may execute a function of an application if it is determined that the user has execution authority. For example, the processor 140 may identify the user and may determine whether the identified user has the execution authority. A user with authority to execute each particular function or application may be predetermined. If a user has no execution authority, the processor 140 may provide feedback indicating that the user has no execution authority.

According to an exemplary embodiment, the processor 140 may provide data registered with respect to the identified user. For example, the processor 140 may store different contact lists of each user. When the user selects a function for providing a contact list, the processor 140 may identify the user through the vein authentication and may provide the contact list registered with respect to the identified user.

FIG. 3 is a block diagram of a wearable device 100 according to an exemplary embodiment. Referring to FIG. 3, the wearable device 100 may include a sensor 110, a display unit 120, a memory 130, and a processor 140.

The memory 130 may store biological information which may be used to identify a user. For example, the memory 130 may store biological information about a user's vein, iris, pulse, or finger. The memory 130 may store vein images of both of a user's hands. The memory 130 may store vein images of the back of a user's hand and the palm of a user's hand. The memory 130 may store iris images of both of a user's eyes.

According to an exemplary embodiment, the memory 130 may store a user's data. For example the memory 130 may store a user's music list or contact list, and setting information or interest information about the user. The setting information may include information for wireless communication such as Wi-Fi, 3G, or LTE. In addition, the setting information may include notification information such as a vibration or a ringtone.

The memory 130 may also store user authentication information. For example, the memory 130 may store credit card information, SNS information, etc. The credit card information may include a credit card number, a credit card expiration date, a password, or the like. The SNS information may include an SNS address, an identification (ID), a password, or the like.

The display unit 120 may display a screen for controlling an electronic device through control of a processor 140. The display unit 120 may be a touch panel that receives an input from the user (e.g., touchscreen).

According to an exemplary embodiment, the display unit 120 may display an authentication process. For example, the display unit 120 may display a message while authentication is being performed. In addition, the display unit 120 may display a captured vein image.

FIG. 4 is a flowchart of a method by which a wearable device 100 changes a setting thereof, according to an exemplary embodiment. Referring to FIG. 4, the wearable device 100 may update a setting of a user through vein authentication.

In operation 410, the wearable device 100 may register setting information about a user and a vein image of the user. The setting information may be information for wireless communication, notification information, or the like. The wearable device 100 may receive the setting information from the user and may register the received setting information. For example, the wearable device 100 may receive information from the user about whether the wearable device 100 performs wireless communication connection through Wi-Fi or LTE. In addition, the wearable device 100 may receive a vibration magnitude, a ringtone volume, and/or a ringtone type from the user. The wearable device 100 may also capture and store a vein image and may store the setting information inputted by the user.

In operation 420, the wearable device 100 may capture a vein image of the user when the user is wearing the wearable device 100. The wearable device 100 may sense whether a user is wearing the wearable device 100. When it is determined that a user is wearing the wearable device 100, the wearable device 100 may capture the vein image of the user wearing the wearable device 100.

According to an exemplary embodiment, the wearable device 100 may sense whether a user is wearing the wearable device 100 based on a buckle (e.g., strap), a body temperature sensor, a pulse sensor, a proximity sensor, etc.; however, exemplary embodiments are not limited to these sensing methods.

The buckle may represent a portion that fixes the wearable device 100 to a user's body. When the buckle is fastened to the wearable device 100, the wearable device 100 may determine that a user is wearing the wearable device 100.

According to another exemplary embodiment, when a body temperature of the user is sensed by the body temperature sensor, the wearable device 100 may determine that a user is wearing the wearable device 100. The body temperature sensor may be disposed on a contact portion of the wearable device, i.e., the portion that contacts the user when the user wears the wearable device 100.

According to another exemplary embodiment, when a pulse of the user is sensed by the pulse sensor, the wearable device 100 may determine that a user is wearing the wearable device 100. The pulse sensor may be disposed on a portion of the wearable device that contacts the user when the user wears the wearable device 100. For example, in the case of a smart watch, the pulse sensor may be disposed on a portion that comes into contact with a lower portion of a user's wrist.

According to another exemplary embodiment, the wearable device 100 may determine through a proximity sensor whether a user is wearing the wearable device 100. The proximity sensor may be disposed on the contact portion when the user is wearing the wearable device 100. For example, in the case of a smart watch, the proximity sensor may be disposed below the display unit 120 to measure a distance between the smart watch and the user's wrist.

In operation 430, the wearable device 100 may identify the user by comparing the captured vein image with a registered vein image. The wearable device 100 may search for a vein image from among a plurality of vein images stored in the memory 130 that matches the captured vein image. When the wearable device 100 determines that the captured vein image and the registered vein image match each other by a predetermined ratio or more, in terms of a structure, or the like, the wearable device 100 may determine that the captured vein image and the registered vein image match each other. The wearable device 100 may then identify which user is wearing the wearable device 100 by determining which user corresponds to the matching registered vein image.

In operation 440, the wearable device 100 may change a setting of the wearable device 100 by using the setting information of the user. For example, the wearable device 100 may use setting information registered of the user that corresponds to the registered vein image that matches the captured vein image. In other words, the wearable device 100 may use setting information registered with respect to the identified user. The setting information may include information that determines a state of the wearable device 100. The wearable device 100 may change its state based on the setting information of the identified user. For example, the wearable device 100 may confirm music registered with respect to the identified user and may change a ringtone to the confirmed music. In addition, the wearable device 100 may confirm a wireless connection type registered with respect to the identified user and may change the confirmed wireless connection type to Wi-Fi or LTE accordingly.

FIG. 5 is a diagram illustrating a process by which a wearable device 100 changes a setting thereof, according to an exemplary embodiment. Referring to FIG. 5, when a user wears the wearable device 100, the wearable device 100 may identify the user wearing the wearable device 100. The wearable device 100 may update a setting thereof by using setting information of the identified user.

For example, when a first user wears the wearable device 100, the wearable device 100 may compare a captured vein image with first and second vein images. If the captured vein image matches the first vein image, the wearable device 100 may determine that the first user wears the wearable device 100. The wearable device 100 may update the setting thereof by using first setting information registered with respect to the first user.

The memory 130 of the wearable device 100 may store the first setting information of the first user and second setting information of a second user. The first setting information may be setting information registered with respect to the first user. The second setting information may be setting information registered with respect to the second user.

In addition, the memory 130 may store first and second vein images of the first and second users. The first vein image may be a vein image of the first user. The second vein image may be a vein image of the second user.

The first setting information may indicate that LTE is set to an ON state, Wi-Fi is set to an OFF state, GPS is set to an OFF state, Bluetooth is set to an ON state, NFC is set to an ON state, brightness is set to 50%, and a mode is set to a vibration mode. For example, when the first user is wearing the wearable device 100, the wearable device 100 may perform wireless communication connection by using the LTE and may disconnect a Wi-Fi connection.

The second setting information may indicate that the LTE is set to an OFF state, the Wi-Fi is set to an ON state, the GPS is set to an OFF state, the Bluetooth is set to an ON state, the NFC is set to an OFF state, the brightness is set to an automatic mode, and the mode is set to a ringtone mode. For example, when the second user wears the wearable device 100, the wearable device 100 may perform the wireless communication connection by using the Wi-Fi and may disconnect a LTE connection.

The storage of the first setting information, the second setting information, and the first and second vein images with respect to the first and the second users has been described with reference to FIG. 5, but the number of the stored users is not limited, and a plurality of pieces of setting information and vein images with respect to three or more users may be stored in the memory 130. Furthermore, the setting information is not limited to these pieces of information.

FIG. 6 is a flowchart of a method by which a wearable device 100 displays a contact list, according to an exemplary embodiment. Referring to FIG. 6, when a contact is selected, the wearable device 100 may provide a contact list of an identified user.

In operation 610, the wearable device 100 may register the contact list of a user and a vein image of the user. The contact list may include a cellular phone number, a home phone number, an office phone number, a fax number, etc.

In operation 620, when the contact function is selected, the wearable device 100 may capture a vein image of the user wearing the wearable device 100. The selecting of the contact function may represent that the user executes a phone function through an input device of the wearable device 100 or selects a contact icon. In other words, the selecting the contact function may include all cases that the wearable device 100 displays the contact list. The input device may be a device such as a touch panel, a touchscreen, or a mouse. When the contact list is selected, the wearable device 100 may generate an event, which may control the sensor 110 to capture the vein image.

Since the wearable device 100 may store different contact lists for each user, it is necessary to provide the contact list registered with respect to the user currently wearing the wearable device 100. Therefore, the wearable device 100 may control the sensor 110 to capture the vein image in order to identify the user wearing the wearable device 100.

In operation 630, the wearable device 100 may identify the user wearing the wearable device 100 by comparing the captured vein image with the registered vein images.

In operation 640, the wearable device 100 may display the contact list corresponding to the identified user on the display unit 120. The wearable device 100 may control the display unit 120 so as to display the contact list of the identified user.

Since the wearable device 100 provides the contact list to the user through vein authentication, although many users use the wearable device 100, only the user currently wearing the device may view his or her own contact list. Therefore, the wearable device 100 may protect personal information.

FIG. 7 is a diagram illustrating a process by which a wearable device 100 provides a contact list, according to an exemplary embodiment. Referring to FIG. 7, when a contact function is selected, the wearable device 100 may provide a contact list registered with respect to the user that is wearing the wearable device 100.
