Description

Technical Field

[0001] The present disclosure relates to the technical field of keyboards, and particularly to a first electronic device, a fingerprint recognition method and device, and a storage medium. Background Art

[0002] Fingerprint unlocking has been widely used in the daily life of the public. Electronic devices such as mobile phones, tablet computers, or laptop computers are all equipped with fingerprint unlocking functions to ensure user privacy and security.

[0003] Currently, laptop computers adopt an integrated hardware design of the keyboard and the host, and the fingerprint hardware can be integrated into the keyboard keys, and the keyboard can be used to complete the system fingerprint unlocking. However, since the existing wireless keyboards are separated from electronic devices such as tablet computers in terms of hardware, the system unlocking of tablet computers generally needs to rely on the fingerprint hardware part integrated on the tablet computer side to complete.

[0004] However, the existing keyboards usually do not have fingerprint hardware. Even if some keyboards are equipped with fingerprint hardware, the fingerprint-related information cannot be transmitted between the keyboard and the tablet computer.

[0105] Here, exemplary embodiments will be described in detail, and examples thereof are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims

[0106] The following will describe in detail the technical solutions provided by each embodiment of the present disclosure with reference to the drawings

[0107] In the related art, the fingerprint unlocking function of current electronic devices such as tablet computers generally relies on fingerprint hardware integrated on the computer side, and wireless keyboards do not come with fingerprint hardware. Even for some keyboards equipped with fingerprint hardware, fingerprint-related information cannot be transmitted between the keyboard and the tablet computer. The fingerprint can only be used as the switch of the keyboard itself to control the locking and unlocking of the keyboard, and it is even more impossible to unlock the computer system, resulting in inconvenience for users.

[0108] For the few keyboards that can complete fingerprint data transmission, due to security and compatibility issues, they can only be used on devices such as laptops and desktop computers. At the same time, all fingerprint collections on the keyboard side are only for collection use, and all fingerprint-related information needs to be transmitted back to the computer side for processing. The fingerprint-related information is prone to being captured and attacked during air transmission, and fingerprint privacy data may be intercepted, copied, and tampered with, with a low security level.

[0109] Based on this, the embodiments of the present disclosure provide a first electronic device. Figure 1 It is a structural schematic diagram of a first electronic device shown according to an exemplary embodiment Figure 1 , as Figure 1 shown, the first electronic device 1 provided by the embodiments of the present disclosure may at least include:

[0110] A housing 11, provided with a fingerprint collection area 111;

[0111] A keyboard body 12, disposed at a different position from the fingerprint collection area 111 on the housing 11;

[0112] A fingerprint recognition module 13, located inside the housing 11 and disposed at the fingerprint collection area 111, configured to recognize a to-be-recognized object acting on the fingerprint collection area 111 to obtain a recognition result;

[0113] A control module 14, connected to the fingerprint recognition module 13, configured to send a recognition request to a second electronic device that has established a wireless communication connection with the first electronic device 1, where the recognition request carries the recognition result, and the recognition result is used to unlock the second electronic device.

[0114] In the embodiments of the present disclosure, the above first electronic device may be a wireless external input device of the above second electronic device; for example, the above first electronic device may be a wireless keyboard. The above second electronic device may be a mobile phone, a tablet computer, or other electronic devices that can establish a wireless communication connection with the above first electronic device, etc., and the embodiments of the present disclosure do not make limitations.

[0115] The above housing may be the outer shell of the above first electronic device; the above keyboard body may be the keyboard keys provided on the above housing.

[0116] The above fingerprint collection area can be set on the above housing, and is on the same side of the above housing as the above keyboard body but at different positions; the above first electronic device can collect the fingerprint information of the user in this fingerprint collection area.

[0117] The above fingerprint recognition module can be a module for fingerprint recognition of the object to be recognized acting on the fingerprint collection area. The above object to be recognized can be the user acting on the above fingerprint collection area. The above recognition result can be the result obtained after recognizing the fingerprint information of the object to be recognized; for example, the above recognition result can be recognition success or recognition failure.

[0118] It can be understood that when the above first electronic device detects that the object to be recognized acts on the fingerprint collection area, the above fingerprint recognition module can collect the current fingerprint information of the object to be recognized, and recognize this current fingerprint information based on the pre-stored fingerprint template to obtain a recognition result.

[0119] The above control module can be the microcontroller unit (MCU) of the above first electronic device; the above control module is located in the above housing and can be connected to the above fingerprint recognition module through an asynchronous serial interface.

[0120] Here, the recognition result obtained by the above fingerprint recognition module can be sent to the above control module, and the above control module can carry this recognition result in the recognition request to send this recognition request to the second electronic device that has established a communication connection with the first electronic device, so that the second electronic device can perform fingerprint unlocking based on this recognition request.

[0121] In some embodiments, as Figure 1 shown, a connection line 15 is formed between the fingerprint recognition module 13 and the control module 14; wherein, when the object to be recognized acts on the fingerprint collection area 111, the electrical signal of the connection line 15 changes;

[0122] The control module 14 is further configured to control the fingerprint recognition module 13 to recognize the object to be recognized when the electrical signal of the connection line 15 changes.

[0123] In this way, when it is detected that the electrical signal of the connection line between the fingerprint recognition module and the control module changes, the control module can control the fingerprint recognition module to recognize the object to be recognized acting on the fingerprint collection area, so as to be more convenient to implement fingerprint recognition of the object to be recognized on the first electronic device side.

[0124] Among them, the above connection line can be the connection line between the pin of the above fingerprint recognition module located at the above fingerprint collection area and the above control module.

[0125] Exemplarily, when there is no user contact at the above fingerprint acquisition area, the electrical signal of the above connection line remains unchanged all the time; when the user's finger touches or presses the above fingerprint acquisition area, the electrical signal of the above connection line changes. For example, the voltage of the electrical signal is less than the voltage when there is no user contact with the fingerprint acquisition area.

[0126] It can be understood that when it is detected that the electrical signal of the connection line between the fingerprint recognition module and the control module changes, the above control module can control the above fingerprint recognition module to collect the fingerprint information of the object to be recognized, and recognize the fingerprint information based on the pre-stored fingerprint template.

[0127] In an embodiment of the present disclosure, as Figure 1 shown, the fingerprint recognition module 13 has an on-off pin 134, and the on-off pin 134 is located at the fingerprint acquisition area 111 and is electrically connected to the control module 14;

[0128] The connection line 15 is the line for the on-off pin 134 to connect to the control module 14.

[0129] In this way, by setting an on-off pin in the fingerprint acquisition area and connecting the fingerprint recognition module and the control module, it is possible to detect a change in the electrical signal of the connection line between the on-off pin and the control module, so as to control the fingerprint recognition module to recognize the object to be recognized acting on the fingerprint acquisition area, and further facilitate the fingerprint recognition of the object to be recognized on the side of the first electronic device.

[0130] Among them, the above on-off pin can be the interrupt pin of the fingerprint chip in the above fingerprint recognition module. For example, touch_irq; the above on-off pin can realize the monitoring and control of the first electronic device. That is to say, at any time, when the above object to be recognized acts on the above fingerprint acquisition area, the above on-off pin notifies the control module by sending an interrupt signal to the control module so that the control module can control the fingerprint recognition module to perform fingerprint recognition on the object to be recognized.

[0131] In the embodiment of the present disclosure, the above control module has a General Purpose Input / Output (GPIO); the above on-off pin can be connected to the GPIO port to notify the above control module through the GPIO port when the electrical signal of the above connection line changes.

[0132] A first electronic device provided by an embodiment of the present disclosure may include: a housing provided with a fingerprint collection area; a keyboard body disposed at a different position of the housing from the fingerprint collection area; a fingerprint recognition module located inside the housing and disposed at the fingerprint collection area, configured to recognize an object to be recognized acting on the fingerprint collection area to obtain a recognition result; a control module connected to the fingerprint recognition module, configured to send a recognition request to a second electronic device having a wireless communication connection with the first electronic device, the recognition request carrying the recognition result, and the recognition result being used to unlock the second electronic device. In this way, by disposing a fingerprint recognition module at the fingerprint collection area of the first electronic device, an object to be recognized acting on the fingerprint collection area can be recognized, and the control module of the first electronic device can carry the recognition result obtained by the fingerprint recognition module in the recognition request, so as to send the recognition request to the second electronic device having a wireless communication connection with the first electronic device, enabling the second electronic device to perform fingerprint unlocking based on the recognition request, thereby enabling fingerprint unlocking of the second electronic device to be realized on the first electronic device, accelerating the fingerprint unlocking speed of the second electronic device, and improving the performance of fingerprint unlocking; and what the first electronic device sends to the second electronic device is the recognition result, rather than the fingerprint information of the object to be recognized, which can prevent the fingerprint information from being transmitted between the first electronic device and the second electronic device, avoiding the possibility of the fingerprint information being intercepted and tampered with in the wireless communication transmission process, improving the security, and protecting the privacy of the user; at the same time, through the wireless communication connection between the first electronic device and the second electronic device, the secure transmission of the recognition request between the first electronic device and the second electronic device can be completed, and the system of the second electronic device is compatible.

[0133] Figure 2 is a schematic structural diagram of a fingerprint recognition module and a control module in a first electronic device shown according to an exemplary embodiment, as Figure 2 shown, the embodiment of the present disclosure divides the fingerprint recognition module in the Figure 1 shown first electronic device. For example, the fingerprint recognition module may include: a memory and a fingerprint chip.

[0134] As Figure 2 shown, the fingerprint recognition module 13 provided in the embodiment of the present disclosure may include:

[0135] a memory 131 storing authentication information;

[0136] a fingerprint chip 132 connected to the control module 14 and the memory 131, and capable of transmitting the authentication information and the recognition result to the control module 14;

[0137] The control module 14 is further configured to carry the authentication information and the recognition result in the recognition request; wherein, the authentication information is used for the second electronic device to perform authentication.

[0138] In this way, the recognition result and the authentication information in the memory can be transmitted to the control module through the fingerprint chip in the fingerprint recognition module, so that the control module can carry the authentication information and the recognition result in the recognition request and send it to the second electronic device for fingerprint unlocking, thereby improving the security of fingerprint unlocking of the second electronic device.

[0139] Wherein, the above authentication information may be the identity identification information of the second electronic device. The above memory may be a flash memory, which is a form of electronically erasable programmable read-only memory and allows the memory to be erased or written multiple times during operation; flash memory can be used for general data storage and for exchanging and transmitting data between a computer and other digital products.

[0140] In the embodiment of the present disclosure, after the first electronic device and the second electronic device establish a wireless communication connection for the first time, the first electronic device can receive an authentication command sent by the second electronic device, and the authentication command carries the above authentication information, so as to store the authentication information in the above memory. Thus, during subsequent fingerprint recognition, the authentication information and the obtained recognition result are both carried in the recognition request and sent to the second electronic device for fingerprint unlocking.

[0141] The above fingerprint chip may be a module for recognizing an object to be recognized acting on the fingerprint acquisition area; for example, the above fingerprint chip may be the MCU of the above fingerprint recognition module.

[0142] Here, as Figure 2 shown, the above fingerprint recognition module 13 may further include: an acquisition module 133, connected to the above fingerprint chip 132 and located at the above fingerprint acquisition area, and configured to acquire the current fingerprint information of the object to be recognized acting on the above fingerprint acquisition area.

[0143] It can be understood that when the finger of the object to be recognized touches or presses the above fingerprint acquisition area, the above control module can indirectly control the acquisition module to acquire the current fingerprint information of the object to be recognized through the fingerprint chip by detecting a change in the electrical signal of the connection line; the acquisition module can send the current fingerprint information to the fingerprint chip, and the fingerprint chip can recognize the current fingerprint information based on the fingerprint template pre-stored in the above memory to obtain the above recognition result.

[0144] It should be noted that the above-mentioned first electronic device can receive the fingerprint entry command sent by the second electronic device through the control module, and the control module then transparently transmits it to the fingerprint chip. After the fingerprint chip processes the sample fingerprint information collected by the collection module, the fingerprint template is obtained and stored in the above-mentioned memory.

[0145] In some embodiments, as Figure 2 shown, the fingerprint recognition module 13 has a first transmission port TX1; the control module 14 has a first reception port RX1;

[0146] The first transmission port TX1 is connected to the first reception port RX1 and can send the recognition result and the authentication information to the first reception port RX1.

[0147] In this way, the recognition result and the authentication information obtained by the fingerprint recognition module can be transmitted through the first transmission port of the fingerprint recognition module and the first reception port of the control module, so as to realize the secure communication transmission from the fingerprint recognition module to the control module.

[0148] Here, the above-mentioned first transmission port and the above-mentioned first reception port can be asynchronous serial interfaces for the communication transmission from the fingerprint recognition module to the control module.

[0149] Among them, the asynchronous serial interface is the Universal Asynchronous Receiver / Transmitter (UART). The Universal Asynchronous Receiver / Transmitter is a general-purpose serial data bus for asynchronous communication; this general-purpose serial data bus can communicate bidirectionally and can realize full-duplex transmission and reception.

[0150] It should be noted that the above-mentioned first transmission port can be connected to the above-mentioned fingerprint chip; after the fingerprint chip processes and obtains the recognition result, it simultaneously sends the authentication information and the recognition result to the first reception port of the control module through the above-mentioned first transmission port, so that the control module can carry the authentication information and the recognition result in the recognition request and send it to the second electronic device in the subsequent process.

[0151] In some embodiments, as Figure 2 shown, the fingerprint recognition module 13 has a second reception port RX2; the control module 14 has a second transmission port TX2;

[0152] The second transmission port TX2 is connected to the second reception port RX2 and can send the authentication information received by the control module 14 to the second reception port RX2;

[0153] The fingerprint chip 132 is connected to the second receiving port RX2 and is capable of storing the authentication information in the memory 131.

[0154] In this way, the authentication information received by the control module can be transmitted through the second receiving port of the fingerprint recognition module and the second sending port of the control module, so that secure communication transmission from the control module to the fingerprint recognition module can be achieved.

[0155] Among them, the second sending port and the second receiving port can also be asynchronous serial interfaces for communication transmission from the control module to the fingerprint recognition module.

[0156] In the embodiments of the present disclosure, the fingerprint chip can also be connected to the second sending port of the control module through the second receiving port. After receiving the authentication command carrying the authentication information sent by the second electronic device, the control module sends the authentication command through the second sending port to the second receiving port of the fingerprint recognition module, so that the fingerprint chip can store the authentication information carried by the received authentication command in the memory. Thus, when the fingerprint recognition module performs fingerprint recognition subsequently, the authentication information and the obtained recognition result can be carried in the recognition request and sent to the second electronic device for fingerprint unlocking.

[0157] In some embodiments, as Figure 2 shown, the fingerprint recognition module 13 has a first power supply port 135; the control module 14 has a second power supply port 141;

[0158] The first power supply port 135 is connected to the second power supply port 141.

[0159] In this way, the fingerprint recognition module can be powered by connecting the first power supply port of the fingerprint recognition module to the second power supply port of the control module.

[0160] Among them, the first power supply port and the second power supply port can both be analog power supply ports (AVDD).

[0161] Here, the second power supply port can be connected to the power supply module of the first electronic device to supply power to the fingerprint recognition module and the control module through this power supply module.

[0162] In some embodiments, as Figure 2 shown, the fingerprint recognition module 13 has a first grounding port 136; the control module 14 has a second grounding port 142;

[0163] The first grounding port 136 is connected to the second grounding port 142.

[0164] In this way, the first grounding port of the fingerprint recognition module can be connected to the second grounding port of the control module to achieve grounding of the fingerprint recognition module.

[0165] Among them, both the first grounding port and the second grounding port can be ports for connecting a ground wire.

[0166] It can be understood that the first electronic device may further include a circuit board; the control module and a ground wire are provided on the circuit board, and the second grounding port can be connected to the ground wire.

[0167] Figure 3 is a schematic structural diagram of a first electronic device shown according to an exemplary embodiment Figure 2 , such as Figure 3 shown, the first electronic device provided by the embodiments of the present disclosure further adds other components on the basis of the Figure 2 first electronic device shown, for example, a communication module, an encryption module, and a decryption module.

[0168] Such as Figure 3 shown, the first electronic device 1 provided by the embodiments of the present disclosure may further include:

[0169] A communication module 16;

[0170] An encryption module 17, configured to encrypt the information sent to the second electronic device; the information sent to the second electronic device at least includes the recognition result;

[0171] The control module 14, connected to the communication module 16 and the encryption module 17, is configured to send the encrypted information to the second electronic device through the communication module 16.

[0172] In this way, the information encrypted by the encryption module can be sent to the second electronic device through the communication module connected to the control module, thereby improving the security of wireless communication transmission between the first electronic device and the second electronic device.

[0173] Among them, the communication module may include: a Bluetooth communication module, a wireless network communication (WIFI) module, or a near field communication (NFC) module. That is to say, the wireless communication connection method between the first electronic device and the second electronic device may include: Bluetooth wireless connection, WiFi wireless connection, or NFC connection, etc.

[0174] The encryption module may be a module for encrypting the information that needs to be sent to the second electronic device. The information sent to the second electronic device may include: the recognition result, the authentication information of the second electronic device, and the fingerprint entry result of the first electronic device for fingerprint entry, etc.

[0175] In an embodiment of the present disclosure, after receiving the recognition result and authentication information sent by the fingerprint recognition module, the control module may transmit the recognition result and authentication information to the encryption module for encryption processing, and carry the recognition result and authentication information encrypted by the encryption module in the recognition request to be sent to the second electronic device for fingerprint unlocking through the communication module.

[0176] In some embodiments, as Figure 3 shown, the first electronic device 1 may further include:

[0177] A decryption module 18, connected to the communication module 16, is configured to decrypt the information sent by the second electronic device received by the communication module 16.

[0178] In this way, the information sent by the second electronic device received by the communication module can be decrypted through the decryption module connected to the communication module, so that fingerprint unlocking of the second electronic device can be better implemented on the first electronic device.

[0179] Wherein, the decryption module may be a module for decrypting the information sent by the second electronic device received. The information sent by the second electronic device received by the communication module may include: the authentication information sent when the second electronic device is first wirelessly connected to the first electronic device, the query initialization command sent when the second electronic device is not first wirelessly connected to the first electronic device, and the fingerprint entry command sent by the second electronic device, etc.

[0180] It can be understood that after the communication module receives the information sent by the second electronic device, the decryption module may decrypt the information sent by the second electronic device, and then send the decrypted information to the fingerprint recognition module through the control module for processing.

[0181] It should be noted that the first electronic device may encrypt the information sent to the second electronic device through the encryption module, and decrypt the information sent by the second electronic device through the decryption module; or, the first electronic device may also directly encrypt the information that needs to be sent to the second electronic device through the communication module such as a Bluetooth communication module, and decrypt the information received from the second electronic device, etc., which is not limited in the embodiments of the present disclosure.

[0182] Figure 4 is a flowchart showing a fingerprint recognition method according to an exemplary embodiment Figure 1 as Figure 4As shown in the figure, the fingerprint recognition method provided by the embodiments of the present disclosure can be applied to a first electronic device, and may at least include the following steps:

[0183] Step 410: Recognize the object to be recognized acting on the fingerprint acquisition area of the first electronic device to obtain a recognition result.

[0184] Step 420: Send the recognition request to a second electronic device that has established a wireless communication connection with the first electronic device; wherein, the recognition request carries the recognition result, and the recognition result is used to unlock the second electronic device.

[0185] In step 410, when the first electronic device detects that the object to be recognized acts on the fingerprint acquisition area, the fingerprint recognition module of the first electronic device can collect the current fingerprint information of the object to be recognized, and recognize the fingerprint information based on the pre-stored fingerprint template to obtain a recognition result.

[0186] In an embodiment of the present disclosure, step 410 may specifically include:

[0187] Encode the currently collected fingerprint information of the object to be recognized to obtain target fingerprint information.

[0188] Based on the pre-stored fingerprint template, recognize the target fingerprint information to obtain the recognition result.

[0189] In this way, the currently collected fingerprint information can be encoded to obtain target fingerprint information of the same type as the fingerprint template for recognition to obtain a recognition result, so as to better realize fingerprint unlocking of the second electronic device on the first electronic device.

[0190] Wherein, the current fingerprint information may be a fingerprint image of the object to be recognized collected by the first electronic device at the current moment; the target fingerprint information may be digitized fingerprint information obtained by encoding the fingerprint image; the fingerprint template may be information pre-stored in the first electronic device that can unlock the second electronic device.

[0191] It can be understood that the fingerprint template can be obtained by collecting the sample fingerprint information of the user through the fingerprint recognition module of the first electronic device and processing the sample fingerprint information based on the fingerprint entry command received from the second electronic device.

[0192] Specifically, in some embodiments, the fingerprint recognition method may further include:

[0193] In response to the fingerprint entry command sent by the second electronic device, encode the collected sample fingerprint information to obtain the fingerprint template.

[0194] In this way, in response to the fingerprint entry command sent by the second electronic device, the collected sample fingerprint information can be encoded to obtain a fingerprint template, so as to prepare for subsequent fingerprint recognition.

[0195] Among them, the above-mentioned fingerprint entry command can be an instruction for fingerprint entry sent by the second electronic device to the first electronic device. The above-mentioned sample fingerprint information can be a sample fingerprint image of a sample user collected in a fingerprint collection area.

[0196] Here, the encoding process of the above-mentioned sample fingerprint information can be understood as performing data processing on the collected sample fingerprint image, that is, the fingerprint template stored in the first electronic device is not the original collected sample fingerprint image, but the encoded data information, which can prevent the possibility of being intercepted and tampered with in the air during the wireless communication interaction between the first electronic device and the second electronic device, and improve the security of fingerprint recognition.

[0197] In some embodiments, the fingerprint recognition method may further include:

[0198] When it is detected that the fingerprint template is stored, generating a fingerprint entry result corresponding to the fingerprint entry command;

[0199] Sending the fingerprint entry result to the second electronic device;

[0200] Among them, the fingerprint entry result is used for the second electronic device to switch to an identification state.

[0201] In this way, after the first electronic device stores the fingerprint template, it can generate a fingerprint entry result corresponding to the received fingerprint entry command, and send the fingerprint entry result to the second electronic device, so as to realize data synchronization between the first electronic device and the second electronic device.

[0202] Among them, the above-mentioned fingerprint entry result can be the result after fingerprint entry based on the fingerprint entry command; for example, the above-mentioned fingerprint entry result can be successful entry or failed entry.

[0203] In the embodiments of the present disclosure, the second electronic device can switch the working state of the second electronic device based on the above-mentioned fingerprint entry result; for example, the working state of the second electronic device can be switched from a listening state to an identification state.

[0204] In step 420, after receiving the recognition result sent by the fingerprint recognition module, the control module of the first electronic device can carry the recognition result in the recognition request and send the recognition request to the second electronic device, so that the second electronic device can perform fingerprint unlocking based on the recognition request.

[0205] It should be noted that the above recognition request not only carries the above recognition result, but also carries the authentication information of the second electronic device stored in advance.

[0206] In an embodiment of the present disclosure, before step 420, the fingerprint recognition method may further include:

[0207] Obtain the authentication information sent by the second electronic device;

[0208] Carry the authentication information and the recognition result in the recognition request; the authentication information is used for the second electronic device to perform authentication.

[0209] In this way, by carrying the recognition result and the pre-stored authentication information obtained in the recognition request, the recognition request can be sent to the second electronic device in the subsequent process, so that fingerprint unlocking of the second electronic device can be realized on the first electronic device.

[0210] It can be understood that after the above first electronic device sends the above authentication information to the second electronic device for successful authentication, the second electronic device can perform fingerprint unlocking based on the above recognition result.

[0211] Specifically, in some embodiments, the fingerprint recognition method may further include:

[0212] In response to the authentication command sent by the second electronic device, store the authentication information carried by the authentication command in the memory of the first electronic device.

[0213] In this way, by responding to the authentication command sent by the second electronic device, the authentication information carried by the authentication command can be stored in the memory of the first electronic device, so as to prepare for subsequent fingerprint recognition.

[0214] Wherein, the above authentication command may be an instruction sent by the above second electronic device to the above first electronic device for authentication during subsequent fingerprint unlocking.

[0215] It should be noted that after the above first electronic device stores the authentication information carried by the above authentication command, there is no need to return the result corresponding to the authentication command to the second electronic device. Only when performing fingerprint unlocking on the second electronic device subsequently, carry the authentication information and the recognition result together in the above recognition request to send the recognition request to the second electronic device for fingerprint unlocking.

[0216] In some embodiments, the fingerprint recognition method may further include:

[0217] Encrypt the recognition result and carry the encrypted recognition result in the recognition request.

[0218] In this way, by encrypting the recognition result and carrying the encrypted recognition result in the recognition request, the security of subsequent wireless communication interaction with the second electronic device can be improved.

[0219] Here, in the embodiments of the present disclosure, the above authentication information can also be encrypted, and both the encrypted recognition result and the authentication information are carried in the recognition request to send the recognition request to the second electronic device, thereby preventing the possibility of being intercepted and tampered with in the air during the wireless communication interaction between the first electronic device and the second electronic device, and enhancing the security of fingerprint recognition.

[0220] A fingerprint recognition method provided by an embodiment of the present disclosure recognizes an object to be recognized acting on a fingerprint collection area of the first electronic device to obtain a recognition result; sends the recognition request to a second electronic device that has established a wireless communication connection with the first electronic device; wherein, the recognition request carries the recognition result, and the recognition result is used to unlock the second electronic device. In this way, by recognizing the object to be recognized acting on the fingerprint collection area of the first electronic device and sending the recognition request carrying the recognition result to the second electronic device that has established a wireless communication connection with the first electronic device, the second electronic device can perform fingerprint unlocking based on the recognition request, thereby enabling fingerprint unlocking of the second electronic device on the first electronic device, accelerating the fingerprint unlocking speed of the second electronic device, and improving the performance of fingerprint unlocking; and what the first electronic device sends to the second electronic device is the recognition result, rather than the fingerprint information of the object to be recognized, which can prevent the fingerprint information from being transmitted between the first electronic device and the second electronic device, avoiding the possibility of the fingerprint information being intercepted and tampered with in the air during wireless communication transmission, enhancing the security, and protecting the privacy of users; at the same time, through the wireless communication connection between the first electronic device and the second electronic device, the secure transmission of the recognition request between the first electronic device and the second electronic device can be completed, and the system of the second electronic device is compatible.

[0221] In some embodiments, the fingerprint recognition method may further include:

[0222] Detect the electrical signal of the connection line between the on-off pin of the first electronic device and the control module;

[0223] When it is detected that the electrical signal of the connection line changes, recognize the object to be recognized.

[0224] In this way, when a change in the electrical signal of the connection line between the on-off pin of the first electronic device and the control module is detected, the object to be recognized can be recognized, so that the timing of fingerprint recognition by the first electronic device can be better controlled.

[0225] It can be understood that when the change in the electrical signal of the connection line is detected, it means that the finger of the object to be recognized touches or presses the fingerprint collection area of the first electronic device; that is to say, when it is detected that the object to be recognized acts on the fingerprint collection area, the fingerprint recognition module of the first electronic device recognizes the object to be recognized.

[0226] In some embodiments, the fingerprint recognition method may further include:

[0227] In response to the query initialization command sent by the second electronic device, generate the configuration information of the fingerprint recognition module in the first electronic device;

[0228] Send the configuration information to the second electronic device;

[0229] Wherein, the configuration information is used for the second electronic device to switch to the listening state.

[0230] In this way, by responding to the query initialization command sent by the second electronic device, the configuration information of the fingerprint recognition module in the first electronic device can be generated and sent to the second electronic device, so that the working state of the second electronic device can be switched.

[0231] Wherein, the above query initialization command may be an instruction sent by the second electronic device to the first electronic device for querying the initialization situation of the fingerprint recognition module. The above configuration information may be information related to each module in the fingerprint recognition module. For example, the above configuration information may be the status information corresponding to each module in the fingerprint recognition module.

[0232] In the embodiments of the present disclosure, after the first electronic device sends the configuration information to the second electronic device, the second electronic device can switch its working state to the listening state, that is, it can listen to fingerprint entry and other operations occurring on the first electronic device.

[0233] In some embodiments, the fingerprint recognition method may further include:

[0234] In response to the fingerprint deletion command sent by the second electronic device, delete the recognition result.

[0235] In this way, by responding to the fingerprint deletion command sent by the second electronic device, fingerprint-related information such as the recognition result stored on the first electronic device can be deleted, so as to ensure the security of fingerprint unlocking of the second electronic device.

[0236] Wherein, the above fingerprint deletion command may be an instruction for deleting fingerprint-related information sent by the second electronic device to the first electronic device.

[0237] It should be noted that after receiving the above fingerprint deletion command, the first electronic device may also delete the stored fingerprint-related information. For example, authentication information or fingerprint templates, etc.; in the case where the second electronic device disconnects the wireless communication connection with the first electronic device, the second electronic device may send the fingerprint deletion command to the first electronic device, and at the same time, the second electronic device also needs to delete the stored fingerprint-related information, such as identification requests or fingerprint entry results, etc.

[0238] Figure 5 is a schematic flowchart of a fingerprint recognition method shown according to an exemplary embodiment Figure 2 , such as Figure 5 shown, the fingerprint recognition method provided by the embodiments of the present disclosure can be applied to a second electronic device and may at least include the following steps:

[0239] Step 510: Receive an identification request sent by a first electronic device that has established a wireless communication connection with the second electronic device;

[0240] Step 520: Perform fingerprint unlocking based on the recognition result carried in the identification request.

[0241] In step 510, the above second electronic device receives the identification request sent by the above first electronic device, which may carry the recognition result obtained after the above first electronic device performs fingerprint recognition, so as to perform fingerprint unlocking based on this recognition result subsequently.

[0242] In step 520, the above second electronic device can perform fingerprint unlocking based on the recognition result carried in the above identification request. That is to say, if the recognition result is successful recognition, the above second electronic device successfully performs fingerprint unlocking; if the recognition result is failed recognition, the above second electronic device fails to perform fingerprint unlocking.

[0243] In some embodiments, the identification request further carries authentication information; step 520 may specifically include:

[0244] When the authentication is successful based on the authentication information, perform fingerprint unlocking based on the recognition result.

[0245] In this way, by performing fingerprint unlocking based on the recognition result when the authentication based on the authentication information is successful, the security of implementing fingerprint unlocking of the second electronic device on the first electronic device can be better improved.

[0246] Here, successful authentication based on authentication information can be understood as that the authentication information carried in the above recognition request matches the above second electronic device, that is, the second electronic device successfully authenticates the first electronic device.

[0247] Specifically, in an embodiment of the present disclosure, the fingerprint recognition method may further include:

[0248] When it is detected that the first electronic device is the first connected device of the second electronic device, an authentication command is sent to the first electronic device; the authentication command carries the authentication information.

[0249] In this way, when it is detected that the first electronic device is the first connected device of the second electronic device, an authentication command carrying authentication information can be sent to the first electronic device, so as to prepare for subsequent fingerprint unlocking.

[0250] Among them, the first electronic device being the first connected device of the second electronic device can be understood as establishing the first wireless communication connection between the first electronic device and the second electronic device.

[0251] It should be noted that after the second electronic device sends the authentication command to the first electronic device, it will not receive the result corresponding to the authentication command returned by the first electronic device again, and will only receive the authentication information again when the first electronic device performs fingerprint unlocking on the second electronic device later to authenticate the first electronic device.

[0252] In some embodiments, step 520 may specifically include:

[0253] When it is detected that the working state of the second electronic device is the recognition state, fingerprint unlocking is performed based on the recognition result carried in the recognition request.

[0254] In this way, when it is detected that the working state of the second electronic device is the recognition state, fingerprint unlocking can be performed based on the recognition result carried in the recognition request, so as to better implement fingerprint unlocking of the second electronic device on the first electronic device.

[0255] It can be understood that after the working state of the second electronic device is switched from the listening state to the recognition state, the fingerprint unlocking module of the second electronic device is ready, that is, it can perform fingerprint unlocking at any time based on the recognition request sent by the first electronic device.

[0256] In some embodiments, step 520 may specifically include: decrypting the recognition result and performing fingerprint unlocking based on the decrypted recognition result. In this way, fingerprint unlocking of the second electronic device on the first electronic device can be better implemented.

[0257] In the embodiments of the present disclosure, the above-mentioned second electronic device may also decrypt the authentication information. After successfully authenticating the first electronic device based on the decrypted authentication information, fingerprint unlocking is performed based on the decrypted recognition result, thereby improving the security of wireless communication interaction between the first electronic device and the second electronic device.

[0258] A fingerprint recognition method provided by the embodiments of the present disclosure includes receiving an identification request sent by a first electronic device that has established a wireless communication connection with the second electronic device; performing fingerprint unlocking based on the recognition result carried in the identification request. In this way, by receiving the identification request sent by the first electronic device that has established a wireless communication connection with the second electronic device, fingerprint unlocking can be performed based on the recognition result carried in the identification request, thereby enabling fingerprint unlocking of the second electronic device on the first electronic device, accelerating the fingerprint unlocking speed of the second electronic device, and improving the performance of fingerprint unlocking; moreover, the second electronic device receives the recognition result sent by the first electronic device instead of the fingerprint information of the object to be recognized, which can prevent the fingerprint information from being transmitted between the first electronic device and the second electronic device, avoiding the possibility of being intercepted and tampered with in the wireless communication transmission process, improving security, and protecting the privacy of users; at the same time, through the wireless communication connection between the first electronic device and the second electronic device, the secure transmission of the identification request between the first electronic device and the second electronic device can be completed, and the system of the second electronic device is compatible.

[0259] In some embodiments, the fingerprint recognition method may further include:

[0260] When it is detected that the working state of the second electronic device is the listening state, sending a fingerprint entry command to the first electronic device;

[0261] Receiving the fingerprint entry result returned by the first electronic device in response to the fingerprint entry command;

[0262] Based on the fingerprint entry result, switching the working state of the second electronic device from the listening state to the recognition state.

[0263] In this way, when it is detected that the working state of the second electronic device is the listening state, a fingerprint entry command can be sent to the first electronic device, and the fingerprint entry result returned by the first electronic device in response to the fingerprint entry command can be received, so as to switch the working state of the second electronic device from the listening state to the recognition state based on the fingerprint entry result, thereby better preparing for subsequent fingerprint unlocking of the second electronic device on the first electronic device.

[0264] Here, the operating state of the second electronic device is the listening state, which can be understood as the second electronic device being able to listen to operations such as fingerprint entry occurring on the first electronic device. The operating state of the second electronic device is the recognition state, which can be understood as the module for fingerprint unlocking of the second electronic device being ready, that is, being able to perform fingerprint unlocking at any time based on the recognition request sent by the first electronic device.

[0265] It should be noted that before the listening state of the second electronic device is in the recognition state, that is, the operating state of the second electronic device can only be switched to the recognition state after being in the listening state.

[0266] In some embodiments, the fingerprint recognition method may further include:

[0267] When it is detected that the first electronic device is a historical connection device of the second electronic device, send a query initialization command to the first electronic device;

[0268] Receive the configuration information returned by the first electronic device in response to the query initialization command;

[0269] Based on the configuration information, switch the operating state of the second electronic device to the listening state.

[0270] In this way, when it is detected that the first electronic device is a historical connection device of the second electronic device, a query initialization command can be sent to the first electronic device, and the configuration information returned by the first electronic device in response to the query initialization command can be received, so as to switch the operating state of the second electronic device to the listening state based on this configuration information, thereby being able to better prepare for subsequent fingerprint entry on the first electronic device.

[0271] Here, the second electronic device can determine the status information corresponding to each module in the first electronic device based on the configuration information sent by the first electronic device, thereby switching the operating state of the second electronic device to the listening state to listen to operations such as fingerprint entry occurring on the first electronic device.

[0272] In some embodiments, the fingerprint recognition method may further include:

[0273] When the second electronic device disconnects the wireless communication connection with the first electronic device, delete the recognition request sent by the first electronic device, and send a fingerprint deletion command to the first electronic device.

[0274] In this way, when the second electronic device disconnects the wireless communication connection with the first electronic device, fingerprint-related information such as the identification request on the second electronic device can be deleted, and a fingerprint deletion command can be sent to the first electronic device, thereby ensuring the security of fingerprint unlocking on the second electronic device.

[0275] In the embodiments of the present disclosure, the disconnection of the wireless communication connection between the second electronic device and the first electronic device can be understood as that the second electronic device no longer conducts a wireless communication connection with the first electronic device, that is, the second electronic device has replaced the input device for the new wireless communication connection.

[0276] It should be noted that the preconditions for the second electronic device to delete the identification request and send a fingerprint deletion command to the first electronic device may include: the second electronic device no longer conducts a wireless communication connection with the first electronic device, or the second electronic device has replaced the new fingerprint unlocking object, etc., and the embodiments of the present disclosure do not make limitations.
