Description

Smart watch

The present invention relates to a smart watch, particularly a smart watch that integrates multiple functions for identification.

When performing business in many industries, it is often necessary to identify the identity through the device, such as a user logging in to a corporate computer or personal online account. When the identification fails, the device will determine that there is a doubt about the legitimacy of the user's identity, and directly issue a formal warning signal to notify the relevant management personnel and/or the police unit. Common ways of identification 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 troubles for the user terminal, the management terminal 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 present invention provides a smart watch that integrates the functions of physical sign detection and fingerprint recognition, can objectively judge the legitimacy of the user's identity, and reduce the probability of falsely touching the warning signal caused by a single recognition method.

According to an embodiment of the present invention, a smart watch is disclosed, which is communicatively connected to a remote server. The smart watch includes a strap and a body. The watchband includes a physical sign measuring device, which has a sensing surface attached to the watchband, and the physical sign measuring device is used to sense the user's physical signs through the sensing surface to obtain physical sign signals. The main body is pivotally connected to the strap, and the main body includes a touch display panel, a wireless transmission circuit, a fingerprint sensor and a processor. The wireless transmission circuit communicates with the remote server. The fingerprint sensor is used to capture the user's fingerprint image. The processor is electrically connected to the touch display panel, the physical sign measuring device, the fingerprint sensor and the wireless transmission circuit. The processor is used to analyze the physical sign signal to obtain a plurality of physiological data and control the touch display panel to display the physiological data. The processor further compares the value of each physiological data to the corresponding warning value, and the processor is used to calculate the value of the physiological data When one reaches the corresponding warning value, a trigger command is generated, and the trigger command is sent to the remote server through the wireless transmission circuit, and the processor is further used to perform image processing on the fingerprint image to extract a plurality of fingerprint characteristic data, and The fingerprint characteristic data is converted into fingerprint data, and the processor further controls the wireless transmission circuit to send the fingerprint data to the remote server. Among them, the processor determines whether the remote server returns an authentication failure message about fingerprint data and whether a trigger command is generated, and then determines whether to send the first level prompt signal or the second level to the remote server through the wireless transmission circuit Warning signal, where the alert level of the second level alert signal is greater than the alert level of the first level alert signal.

To sum up, in the smart watch proposed in the present invention, it is mainly based on the multi-function discrimination of fingerprint recognition combined with physical sign detection. When the fingerprint recognition fails but the physical sign detection is normal, only a relatively low alert signal is issued. . When fingerprint recognition fails and the physical signs are detected abnormally, a relatively high alert level is issued. Through the setting of different alert levels, the legitimacy of the user's identity can be judged more objectively, thereby overcoming the shortcomings of the existing single identification method and reducing the troubles of users and management personnel.

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

The detailed features and advantages of the present invention will be described in detail in the following embodiments. The content is sufficient to enable anyone familiar with 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 patent application and the drawings. Anyone who is familiar with relevant skills can easily understand the purpose 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 by any viewpoint.

Please refer to FIGS. 1 and 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 view of the smart watch according to an embodiment of the present invention. Function 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 watchband B1 includes a physical sign measuring device 101, and the physical sign measuring device 101 has a sensing surface SE attached to the watchband B1. Specifically, the host (not shown) of the physical sign measuring device 101 is arranged in the watch band B1, wherein the sensing surface SE of the physical sign measuring device 101 is attached to the inner edge surface of the watch band B1 and 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. In other words, the sensing surface SE senses the physical signs of the user and returns the acquired physical signs to the host of the physical sign measuring device 101. In practice, the attachment position of the sensing surface SE is located on the inner surface of the strap B1 close to the pivotal position of the body B2 and the strap B1, so that the user's physical signs, such as pulse or blood pressure, can be easily detected. The 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. Among them, 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 to analyze the aforementioned physical sign signals to obtain a plurality of physiological data. In other words, the processor 104 obtains the corresponding pulse value and blood pressure value as physiological data from the physical sign signal including the pulse or blood pressure change received by the physical sign measuring device 101, and the processor 104 controls the touch display The panel 102 displays physiological data. The touch display panel 102 displays the physiological data in the form of numerical values or graphs, and the present invention is not limited thereto.

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 storage space to store multiple warning values for comparison. For example, the processor 104 compares the value of each physiological data to the corresponding warning value, and when it is determined that any one or both of the physiological data (such as pulse value and blood pressure value) exceeds its 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 user's fingerprint image. In detail, the body B2 of the smart watch 1 has an operating interface for the user's finger to press, allowing the fingerprint sensor 105 to obtain the fingerprint image on the user's finger, and send the fingerprint image back to the processor 104. The processor performs an image processing on the fingerprint image to extract a plurality of fingerprint characteristic data, and convert the fingerprint characteristic data into fingerprint data. In practice, the image processing described includes image sharpening processing, which includes processing processes such as binarization, noise filtering, and line thinning, and extracts texture features from the processed clear image, including texture division such as fingerprints. Cross and end to generate fingerprint characteristic 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 this fingerprint comparison database stores multiple fingerprint data. A processor (not shown in the figure) built in the remote server 2 compares the fingerprint data sent by the smart watch 1 with a corresponding piece of 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. According to the fingerprint verification result, the verification message may include an authentication success message or an authentication failure message.

In one embodiment, the processor 104 determines whether the remote server 2 returns an authentication failure message about the fingerprint data and whether a trigger command is generated, and then determines whether to send a second message to the remote server 2 through the wireless transmission circuit 103. First-level reminder signal or second-level reminder signal.

In detail, on the one hand, the processor 104 determines whether there is an authentication failure message of the fingerprint data, and the processor 104 determines whether to trigger the command on the other hand. Based on the above two determinations, the processor 104 can choose to issue the first The first-level warning signal or the second-level warning signal, where the alert level of the second-level alert signal is greater than the alert level of the first-level alert 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, the user's physical signs (such as blood pressure or pulse) do not have obvious abnormalities, so the processor 104 determines that the user's physiological data value has not reached the warning value and therefore does not generate a trigger command. At this time, the processor 104 will only issue a first-level prompt signal with a lower alert level. In practice, when the remote server 2 receives the first-level prompt signal, it will recognize that the user may not be able to pass the fingerprint verification process due to dirt or moisture on the finger, and it is not the user’s legality. has a problem. Therefore, the remote server 2 will only notify the personnel of the management terminal to continue monitoring the user, and will not directly notify the police unit.

In the aforementioned second 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, and the user's physical signs (such as blood pressure or pulse) also occur Obviously abnormal phenomenon, therefore, the processor 104 determines that the physiological data value of the user 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 notify the police unit.

Through the above-mentioned comprehensive judgment combined with fingerprints and physiological data, the smart watch 1 proposed in the embodiment of the present invention can correspondingly issue different warning levels of warning signals according to different situations, so that it can avoid directly notifying the police unit based on a single recognition result. Cause no unnecessary troubles, and then achieve the objective of objective identification.

In one embodiment, in order to prevent the user's fingerprint feature points from being stolen during the data transmission process, 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 characteristic data with the first public key to generate fingerprint data. Then, the processor 104 will further send 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 fingerprint characteristic data. In other words, the remote server 2 decrypts the fingerprint data through the first private key to obtain the feature point data, which can prevent someone from stealing the user's fingerprint.

In one embodiment, the processor 104 further generates an authentication code based on 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 may further generate an authentication code based on the first public key and a hash value of, for example, fingerprint characteristic data. The processor 104 further transmits the authentication code to the remote server 2. The remote server 2 forwards this authentication code to the user's mobile device (not shown in the figure).

At this time, the user can know the authentication code through his mobile device, and input the authentication code into the smart watch 1 he is wearing, so that the internal processor 104 can obtain the authentication code from the authentication message according to the authentication code. Parse out the authentication success message. Through the above method, it can be avoided that when the remote server 2 mistakenly sends the verification message (including the authentication success message) to another person’s smart watch, the other person can directly invade the original according to the authentication success message. The user's account.

Please refer to FIG. 2 and FIG. 3 together. FIG. 3 is a zoning diagram of a user's area 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 multiple positioning 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 positioning signals to track the smart watch. s position. In detail, as shown in Figure 3, different wireless network base stations W1~W7 are respectively set in different areas A~G. When the user UE wearing smart watch 1 moves in this area, his watch The internal locator 106 will continuously detect the wireless network signal of each wireless network base station W1~W7 within a specific range as a positioning signal.

Depending on the current location of the user UE, the wireless network signal strength of each wireless network base station W1 to W7 detected by the locator 106 will vary. The closer the user UE is to a certain wireless network base station (such as W1), the stronger the signal strength of this wireless network base station. 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 query the location information to determine the current location of the user UE according to the signal strength of each positioning signal (ie, wireless network signal) from each wireless network base station. Taking the embodiment of FIG. 3 as an example, the locator 106 detects signals from wireless network base stations W1~W7. Among them, the signal strength of wireless network base station W1 is the highest, and the signal strength of wireless network base station W3 is the second. The signal strength of wireless network base stations W2, W4, and W6 is slightly weaker than that of wireless network base station W3, while the signal strength of wireless network base stations W5 and W7 is the weakest. After the locator 106 returns the positioning signals 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 position of is approximately between area A and area C.

Through the above-mentioned 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 a user UE wearing a smart watch 1 enters a restricted area E (for example, an area where a large amount of cash is stored in a bank), the remote server 2 correspondingly sends a 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 aforementioned 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 unlock signal. If the unlock signal is not received within a predetermined time (for example, 5 seconds), the processor 104 generates the first level alarm signal. In this case, that is, if the user UE itself is authorized to enter the control area E (for example, bank manager level or above), the user UE can cancel the prompt message by the unlock signal within a predetermined time Picture. If the user UE (basic bank employee) is not authorized to enter the restricted area E, the user UE cannot provide a password, fingerprint, or voiceprint as an unlock signal within a predetermined time to remove the prompt message screen. 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 are internal grassroots employees who try to enter the control area E by fraudulently using the identity of their 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 issues a second-level alarm signal. Taking the actual situation as an example, suppose that a gangster hijacks a user UE (such as a banker) equipped with a smart watch 1 and enters the restricted area E and wants to obtain 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 rise rapidly due to nervousness and panic), which causes the processor 104 to correspondingly generate 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 of 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 report the police unit to the scene to deal with it.

To sum up, in the smart watch proposed in the present invention, it is mainly based on the multi-function discrimination of fingerprint recognition combined with physical sign detection. When the fingerprint recognition fails but the physical sign detection is normal, only a relatively low alert signal is issued. . When fingerprint recognition fails and the physical signs are detected abnormally, a relatively high alert level is issued. Through the setting of different alert levels, the legitimacy of the user's identity can be judged more objectively, thereby overcoming the shortcomings of the existing single identification method and reducing the troubles of users and management personnel.

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