The present invention relates to a smart watch, especially a smart watch integrating multiple functions for identification.

When performing business in many industries, identification is often required through devices, such as users logging in to corporate computers or personal online accounts. When the identity recognition fails, the device will judge that the user's identity has doubts about the legitimacy of the user's identity, and thus directly issue a formal warning signal to notify the relevant management personnel and/or the police unit. Common identification methods are, for example, face recognition, fingerprint recognition or iris recognition.

However, a single identification method is not objective enough, and it is easy to send a warning signal by mistake, causing unnecessary trouble to the user end, the management end and/or the police unit. Therefore, in various industries, there is a need for a device that can collect different types of data and conduct comprehensive analysis to determine the legitimacy of the user's identity.

The above description of the present disclosure and the following description of the embodiments are used to demonstrate and explain the spirit and principle of the present invention, and provide further explanation of the scope of the patent application of the present invention.

The detailed features and advantages of the present invention are described in detail below in the embodiments, and the content is sufficient to enable any person skilled in the relevant art to understand the technical content of the present invention and implement it accordingly, and according to the content disclosed in this specification, the scope of the patent application and the drawings , any person skilled in the related art can easily understand the related objects and advantages of the present invention. The following examples further illustrate the viewpoints of the present invention in detail, but do not limit the scope of the present invention in any viewpoint.

Please refer to FIG. 1 and FIG. 2 together. FIG. 1 is a schematic diagram of the appearance of a smart watch according to an embodiment of the present invention, and FIG. 2 is a schematic diagram of a smart watch according to an embodiment of the present invention. Functional block diagram. As shown in the figure, the smart watch 1 is communicatively connected to a remote server 2, which includes a watchband B1 and a body B2, wherein the body B2 is pivotally connected to the watchband B1. The watch band B1 includes a physical sign measuring device 101 , and the physical sign measuring device 101 has a sensing surface SE attached to the watch band B1 . Specifically, the host (not shown) of the vital sign measuring device 101 is disposed in the watch band B1, wherein the sensing surface SE of the vital sign measuring device 101 is attached to the inner edge surface of the watch band B1 and is connected to the watch band B1 through a connecting line host. The physical sign measuring device 101 can sense the physical sign of the user through the sensing surface SE to obtain the physical sign signal. That is to say, the sensing surface SE senses the physical signs of the user and sends back the acquired physical signs to the host of the physical sign measuring device 101 . In practice, the sticking position of the sensing surface SE is located on the inner edge surface of the strap B1 close to the position where the body B2 and the strap B1 are pivotally connected, so that the user's physical signs, such as pulse or blood pressure, can be easily detected. amount of change.

The body B2 includes a touch display panel 102 , a wireless transmission circuit 103 , a processor 104 and a fingerprint sensor 105 . The processor 104 is electrically connected to the physical sign measuring device 101 , the touch display panel 102 , the wireless transmission circuit 103 and the fingerprint sensor 105 , and the wireless transmission circuit 103 is communicatively connected to the remote server 2 . The processor 104 is used for analyzing the aforementioned vital signs to obtain a plurality of physiological data. That is to say, the processor 104 obtains the corresponding pulse value and blood pressure value as physiological data through calculation on the vital signal including the pulse or blood pressure variation received from the vital sign measuring device 101 , and the processor 104 controls the touch display The panel 102 displays the physiological data, wherein the touch display panel 102 displays the physiological data in the form of a numerical value or a graph, which is not limited in the present invention.

The processor 104 further compares the value of each physiological data to a corresponding warning value, and when one of the values of the physiological data reaches the corresponding warning value, the processor 104 correspondingly generates a trigger instruction. In practice, the processor 104 has a storage space to store a plurality of warning values for comparison. For example, the processor 104 compares the values of each physiological data to the corresponding warning value, and when it is determined that any one or both of the physiological data (eg, the pulse value and the blood pressure value) exceeds the corresponding warning value At this time, the processor 104 generates a trigger command and transmits the trigger command to the remote server 2 through the wireless transmission circuit 103 .

On the other hand, the fingerprint sensor 105 is used to capture the fingerprint image of the user. Specifically, the main body B2 of the smart watch 1 has an operation interface for the user to press the finger, so that the fingerprint sensor 105 obtains the pattern on the user's finger as a fingerprint image, and returns the fingerprint image to the processor 104. The processor performs an image processing on the fingerprint image to extract a plurality of fingerprint feature data, and convert the fingerprint feature data into fingerprint data. In practice, the image processing includes image sharpening processing, which includes binarization, noise filtering, thinning and other processing processes, and texture features are extracted from the processed clear image, including texture points such as fingerprints. fork and end to generate fingerprint feature data.

The processor 104 further controls the wireless transmission circuit 103 to transmit the fingerprint data to the remote server 2 . A fingerprint comparison database (not shown in the figure) is pre-built in the remote server 2, and the fingerprint comparison database stores a plurality of fingerprint data. The processor (not shown) built in the remote server 2 compares the fingerprint data sent from the smart watch 1 with a corresponding fingerprint data in the fingerprint database. The processor of the remote server 2 executes a verification procedure and returns a verification message to the processor 104, wherein according to the result of the fingerprint verification, the verification message may include an authentication success message or an authentication failure message.

In one embodiment, the processor 104 determines whether an authentication failure message about the fingerprint data returned by the remote server 2 is received and whether a trigger command is generated, so as to determine whether to send the first message to the remote server 2 through the wireless transmission circuit 103. Level 1 alert signal or Level 2 alert signal.

Specifically, on the one hand, the processor 104 determines whether an authentication failure message of fingerprint data is received, and on the other hand, the processor 104 determines whether to trigger an instruction. Combining the above two judgments, the processor 104 can choose to send the first The first-level prompt signal or the second-level prompt signal, wherein the alert level of the second-level prompt signal is greater than the alert level of the first-level prompt signal.

In one case, the processor 104 only receives the authentication failure message but does not generate a trigger command. At this time, the processor 104 sends the first-level prompt signal to the remote server 2 through the wireless transmission circuit 103 . In another case, the processor 104 not only receives the authentication failure message but also generates a trigger command. At this time, the processor 104 sends a second-level prompt signal to the remote server 2 through the wireless transmission circuit 103 .

That is, in the aforementioned first case, the processor 104 receives an authentication failure message because the fingerprint data provided by the user fails to pass the verification procedure of the remote server 2 . However, there is no obvious abnormality in the user's physical signs (eg, blood pressure or pulse), so the processor 104 determines that the user's physiological data value does not reach the warning value and thus does not generate a trigger command. At this time, the processor 104 will only issue a first-level prompt signal with a lower alertness level. In practice, when the remote server 2 receives the first-level prompt signal, it will determine that the user may be unable to pass the fingerprint verification process due to dirt or moisture on the fingers, rather than the legitimacy of the user's identity. has a problem. Therefore, the remote server 2 only informs the personnel of the management terminal to continue monitoring the user, and does not directly notify the police unit.

In the second case mentioned above, the processor 104 receives an authentication failure message because the fingerprint data provided by the user fails to pass the verification procedure of the remote server 2, and the user's physical signs (such as blood pressure or pulse) also occur. There is an obvious abnormal phenomenon, so the processor 104 determines that the value of the user's physiological data reaches the warning value, and accordingly generates a trigger command. At this time, the processor 104 will issue a second-level prompt signal with a higher alert level. In practice, when the remote server 2 receives the first-level prompt signal, it will determine that the user intends to impersonate another person's identity, and the remote server 2 will directly send a message to the police unit.

Through the above comprehensive judgment in combination with fingerprints and physiological data, the smart watch 1 proposed in the embodiment of the present invention can correspondingly send out prompt signals of different warning levels according to different situations, so as to avoid directly notifying the police unit based on only a single identification result. Cause no unnecessary trouble, and then achieve the purpose of objective identification.

In one embodiment, in order to prevent the user's fingerprint feature points from being stolen during data transmission, an encryption process is performed before the processor 104 transmits the fingerprint feature data to the remote server 2 . Specifically, the processor 104 receives the first public key from the remote server 2, and encodes the fingerprint feature data with the first public key to generate fingerprint data. Then, the processor 104 further transmits the fingerprint data to the remote server 2 . Wherein, since the first public key is generated by the remote server 2 according to the first private key, only the remote server 2 can decrypt the fingerprint data to obtain the fingerprint characteristic data. That is to say, the remote server 2 decrypts the fingerprint data through the first private key and obtains the feature point data, so as to prevent someone from stealing the user's fingerprint.

In one embodiment, the processor 104 further generates an authentication code according to the first public key, and transmits the authentication code to the remote server 2 through the wireless transmission circuit 103 for the remote server 2 to return the authentication code to the user mobile device. In this embodiment, in addition to using the aforementioned encryption procedure, the processor 104 can further generate the authentication code according to the first public key and a hash value such as fingerprint feature data. The processor 104 further transmits the authentication code to the remote server 2 . The remote server 2 transmits the authentication code to the user's mobile device (not shown in the figure).

At this time, the user can know what the authentication code is through his own mobile device, and input the authentication code into the smart watch 1 he is wearing, so that the internal processor 104 can extract the authentication code from the authentication message according to the authentication code. Parse out the authentication success message. Through the above method, when the remote server 2 mistakenly transmits the authentication message (including the authentication success message) to the smart watch of another person who is fraudulently using, the other person can directly invade the original device according to the authentication success message. User's account.

Please refer to FIG. 2 and FIG. 3 together. FIG. 3 is a zoning diagram of a region where a user is located according to an embodiment of the present invention. As shown in the figure, the smart watch 1 further includes a locator 106 which is electrically connected to the processor 104 . The locator 106 sends a plurality of locating signals to the remote server 2 through the wireless transmission circuit 103, and the remote server 2 can search the location database 201 according to the signal strength of the locating signals, so as to track the smart watch s position. In detail, as shown in FIG. 3, different wireless network base stations W1~W7 are respectively set in different areas A~G. When the user UE equipped with the smart watch 1 moves in this area, the watch The internal locator 106 will continuously detect the wireless network signals of each wireless network base station W1-W7 within a specific range as the positioning signal.

Depending on the current location of the user UE, the strengths of the wireless network signals of the wireless network base stations W1 to W7 detected by the locator 106 may be different. When the location of the user UE is closer to a certain wireless network base station (eg, W1 ), the signal strength of the wireless network base station is stronger. On the contrary, the signal strength of the wireless network base station (such as W5 or W7) is weaker.

In practice, the location database 201 is located in the storage medium (not shown in the figure) of the remote server 2 and stores a map information corresponding to FIG. location information. The processor of the remote server 2 can check the location information to determine the current location of the user UE according to the signal strength of each positioning signal (ie, the wireless network signal) from each wireless network base station. Taking the embodiment of FIG. 3 as an example, the locator 106 detects the signals from the wireless network base stations W1-W7, wherein the signal strength of the wireless network base station W1 is the highest, and the signal strength of the wireless network base station W3 is the second. In other words, the signal strengths of the wireless network base stations W2, W4 and W6 are slightly weaker than that of the wireless network base station W3, and the signal strengths of the wireless network base stations W5 and W7 are the weakest. After the locator 106 sends the positioning signals back to the remote server 2 through the wireless transmission circuit 103, the remote server 2 can search and determine the user UE in the location database 201 according to the signal strength of the positioning signals The current location of is approximately between area A and area C.

Through the above positioning method, the remote server 2 can continuously monitor the position of the smart watch 1 . In one embodiment, when the remote server 2 detects that the smart watch 1 enters the restricted area, the processor 104 receives a prompt message from the remote server 2, and the processor 104 controls the touch display panel 102. A prompt message is displayed. For example, as shown in FIG. 3 , when the user UE equipped with the smart watch 1 enters the control area E (for example, the area where the bank stores a large amount of cash), the remote server 2 sends a corresponding prompt message to the smart watch 1 . At this time, the touch display panel 102 displays a prompt message on the screen to remind the user that the UE has entered the control area E.

In one embodiment, when the above-mentioned prompt message is displayed on the screen of the touch display panel 102, the user UE needs to provide at least one of a password, a fingerprint and a voiceprint as an unlocking signal. If the unlock signal is not received within a predetermined time (eg, 5 seconds), the processor 104 generates a first-level alarm signal. In this case, that is to say, if the user UE has an identity authorized to enter the control area E (for example, the bank manager level or above), the user UE can release the prompt message by itself through the unlock signal within a predetermined time. screen. If the user UE (basic bank employee) is not authorized to enter the control area E, the user UE cannot provide a password, fingerprint or voiceprint as an unlocking signal within a predetermined time to release the prompt message. At this time, the processor 104 sends a first-level alarm signal to the remote server 2 . The administrator of the remote server 2 can investigate whether there is an internal grassroots employee who attempts to enter the control area E by fraudulently using the identity of the boss.

In another embodiment, when a prompt message is displayed on the screen of the touch display panel 102 and the processor 104 also generates a trigger command, the processor 104 sends out a second-level alarm signal. Taking the actual situation as an example to illustrate, suppose that when a criminal kidnaps a user UE (such as a banker) equipped with a smart watch 1 into the control area E and wants to get cash, on the one hand, the touch display panel 102 will display a prompt message on the screen On the other hand, the physical signs of the user UE may be abnormal (for example, the blood pressure and pulse rapidly increase due to nervousness and panic), so that the processor 104 correspondingly generates a trigger command. At this time, the smart watch 1 determines that the user is in danger, and the processor 104 issues a second-level alarm signal. Compared with the first-level alarm signal in the foregoing embodiment, the second-level alarm signal has a higher warning level. When the remote server 2 receives the second-level alarm signal, it will directly notify the police unit to attend the scene.

To sum up, in the smart watch proposed by the present invention, it is mainly based on the multi-functional discrimination based on fingerprint recognition and physical sign detection. When the fingerprint recognition fails but the physical sign detection is not abnormal, only a relatively low alert level prompt signal is issued. . When the fingerprint identification fails and the sign detection is abnormal, a relatively high alert level prompt signal is issued. Through the setting of different alert levels, the legitimacy of the user's identity can be more objectively determined, thereby overcoming the shortcomings of the existing single identification method and reducing the troubles of users and managers.

Although the present invention is disclosed in the foregoing embodiments, it is not intended to limit the present invention. Changes and modifications made without departing from the spirit and scope of the present invention belong to the scope of patent protection of the present invention.
