[0040] In order to make the purpose, technical solution and beneficial technical effects of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described in this specification are only for the purpose of explaining the present invention and are not intended to limit the present invention.

[0041] Example 1:

[0042] The present invention provides a key-type fingerprint unlocking method, which can be applied to Figure 1 In the application environment shown, the touch-tone fingerprint unlocking method is applied to a terminal, wherein the terminal can be, but is not limited to, a mobile phone, a desktop computer, a laptop computer, a PDA, a door lock, and other terminals that require fingerprint unlocking.

[0043] like Figure 2 and Figure 3 As shown, the present invention provides a key-type fingerprint unlocking method, comprising the following steps:

[0044] S1, configuring a dry fingerprint unlocking mode and a wet fingerprint unlocking mode, and setting corresponding fingerprint unlocking thresholds for the dry fingerprint unlocking mode and the wet fingerprint unlocking mode respectively; wherein the fingerprint unlocking threshold of the wet fingerprint unlocking mode is lower than the fingerprint unlocking threshold of the dry fingerprint unlocking mode.

[0045] In this specific embodiment, the application of the button-type fingerprint unlocking method to a mobile phone is used as an example for explanation. In the mobile phone, a fingerprint unlocking mode is originally configured. This fingerprint unlocking mode is generally a dry fingerprint unlocking mode. The fingerprint unlocking function is enabled or disabled by turning on or off the virtual switch of the fingerprint unlocking mode. Through the improvement of the present invention, a wet fingerprint unlocking mode that is different from the original dry fingerprint unlocking mode is added to the mobile phone configuration, and corresponding fingerprint unlocking thresholds are set for the dry fingerprint unlocking mode and the wet fingerprint unlocking mode respectively. For example, the fingerprint unlocking threshold of the dry fingerprint unlocking mode is set to 100%, and the phone can only be unlocked when the acquired fingerprint matches the pre-stored fingerprint 100%; in other words, if the pre-stored fingerprint has 11 fingerprint feature points, when all 11 fingerprint feature points of the pre-stored fingerprint are included in the acquired fingerprint, the acquired fingerprint matches the pre-stored fingerprint 100%, and the phone can be unlocked at this time. For example, the fingerprint unlocking threshold of the wet fingerprint unlocking mode is set to 50%. The device can only be unlocked when the acquired fingerprint matches the pre-stored fingerprint by 50% or more. In other words, if the pre-stored fingerprint has 10 fingerprint feature points, the acquired fingerprint matches the pre-stored fingerprint when at least 5 of the 10 fingerprint feature points of the pre-stored fingerprint are included in the acquired fingerprint, and the device can be unlocked.

[0046] In addition, the fingerprint unlocking threshold of the dry fingerprint unlocking mode and the fingerprint unlocking threshold of the wet fingerprint unlocking mode are set by pulling the setting slider. For example, the fingerprint unlocking threshold of the dry fingerprint unlocking mode is set by pulling the pull ratio of the setting slider to 100%; the fingerprint unlocking threshold of the wet fingerprint unlocking mode is set by pulling the pull ratio of the setting slider to a percentage that matches the wrinkle degree of the wet hand fingerprint. When the setting slider is pulled to zero, anyone's hand fingerprint can be unlocked. When the setting slider is set to 100%, it is in the normal unlocking state, that is, it works in the dry fingerprint unlocking mode. The present invention sets the unlocking percentage according to the wrinkle degree of the wet hand fingerprint, which can unlock conveniently and efficiently.

[0047] In this step, when the user's finger is wet, the fingerprint of the wet finger's wrinkle concave part cannot be collected, and only the fingerprint of the wet finger's wrinkle convex part can be collected to obtain the user's fingerprint. At this time, the user's fingerprint is specifically a wet hand fingerprint.

[0048] S2, determining whether the user's finger is dry or wet by pressing a key, and obtaining the user's fingerprint.

[0049] A press key for collecting fingerprints is arranged at the fingerprint collection position of the mobile phone, a water-absorbing film is arranged on the surface of the press key, and a water-absorbing ring is arranged on the outer circle of the press key.

[0050] When a finger presses a key, a certain amount of pressure is required to press the key. This pressure pushes the moisture on the finger to the water-absorbing film. The water-absorbing film then guides the moisture to the water-absorbing ring at the edge, allowing the water-absorbing ring to absorb the moisture. The water absorption of the water-absorbing ring determines whether the user's finger is dry or wet. The fingerprint can be collected while the finger presses the key.

[0051] S3, according to the user's fingerprint, the terminal is fingerprint unlocked. The unlocking process has two unlocking modes, and each unlocking mode has two unlocking results. The unlocking modes and unlocking results are as follows:

[0052] S3a, if the user's finger is a dry fingerprint, the dry fingerprint unlocking mode is automatically enabled, and the acquired user fingerprint is matched with the pre-stored fingerprint to obtain a first matching degree; when the first matching degree is higher than or equal to the fingerprint unlocking threshold of the dry fingerprint unlocking mode, the terminal is unlocked; when the first matching degree is lower than the fingerprint unlocking threshold of the dry fingerprint unlocking mode, the terminal cannot be unlocked;

[0053] S3b, if the user's finger is wet, the wet fingerprint unlocking mode is automatically enabled, and the acquired user fingerprint is matched with the pre-stored fingerprint to obtain a second matching degree; when the second matching degree is higher than or equal to the fingerprint unlocking threshold of the wet fingerprint unlocking mode, the terminal is unlocked; when the second matching degree is lower than the fingerprint unlocking threshold of the wet fingerprint unlocking mode, the terminal cannot be unlocked.

[0054] When the user's finger is wet, the process of unlocking the terminal specifically includes matching the obtained wet fingerprint with the pre-stored fingerprint to obtain a second matching degree. When the second matching degree is greater than or equal to the fingerprint unlocking threshold of the wet fingerprint unlocking mode, the missing fingerprints in the pre-stored fingerprint that do not match are automatically added to the wet fingerprint, and the terminal is unlocked based on the added wet fingerprint. For example, the fingerprint unlocking threshold of the wet fingerprint unlocking mode is set to 50%. If the pre-stored fingerprint has 10 fingerprint feature points, and 5 of the 10 fingerprint feature points of the pre-stored fingerprint are included in the acquired fingerprint, the remaining 5 missing fingerprints in the pre-stored fingerprint that do not match are automatically added to the wet fingerprint. If the pre-stored fingerprint has 10 fingerprint feature points, and 7 of the 10 fingerprint feature points of the pre-stored fingerprint are included in the acquired fingerprint, the remaining 3 missing fingerprints in the pre-stored fingerprint that do not match are automatically added to the wet fingerprint. The terminal is unlocked based on the added wet fingerprint.

[0055] The present invention proposes a button-type fingerprint unlocking method, which can set the percentage of the unlocking threshold according to the wrinkle degree of wet hands, and achieve the purpose of successful unlocking by appropriately reducing the security level. The unlocking is convenient and efficient.

[0056] Example 2:

[0057] The present invention provides a key-type fingerprint unlocking system, such as Figure 4 As shown, the button-type fingerprint unlocking system includes the following modules:

[0058] An unlocking threshold setting module, which is used to configure a dry fingerprint unlocking mode and a wet fingerprint unlocking mode, and set corresponding fingerprint unlocking thresholds for the dry fingerprint unlocking mode and the wet fingerprint unlocking mode respectively; wherein the fingerprint unlocking threshold of the wet fingerprint unlocking mode is lower than the fingerprint unlocking threshold of the dry fingerprint unlocking mode;

[0059] A dry and wet finger recognition and fingerprint acquisition module, which is used to determine whether the user's finger is dry or wet by pressing a key and obtain the user's fingerprint;

[0060] Fingerprint unlocking module, which is used to,

[0061] If the user's finger is a dry finger, the dry fingerprint unlocking mode is automatically enabled, and the acquired user fingerprint is matched with the pre-stored fingerprint to obtain a first matching degree; when the first matching degree is higher than or equal to the fingerprint unlocking threshold of the dry fingerprint unlocking mode, the terminal is unlocked; when the first matching degree is lower than the fingerprint unlocking threshold of the dry fingerprint unlocking mode, the terminal cannot be unlocked;

[0062] If the user's finger is wet, the wet fingerprint unlocking mode is automatically enabled, and the acquired user fingerprint is matched with the pre-stored fingerprint to obtain a second matching degree; when the second matching degree is higher than or equal to the fingerprint unlocking threshold of the wet fingerprint unlocking mode, the terminal is unlocked; when the second matching degree is lower than the fingerprint unlocking threshold of the wet fingerprint unlocking mode, the terminal cannot be unlocked.

[0063] The unlocking threshold setting module is specifically configured to set the fingerprint unlocking threshold of the dry fingerprint unlocking mode by pulling the setting slider; and set the fingerprint unlocking threshold of the wet fingerprint unlocking mode by pulling the setting slider.

[0064] In the unlocking threshold setting module, the fingerprint unlocking threshold of the dry fingerprint unlocking mode is set by pulling the setting slider to 100%; the fingerprint unlocking threshold of the wet fingerprint unlocking mode is set by pulling the setting slider to a percentage that matches the wrinkle degree of wet hand fingerprints.

[0065] The wet and dry finger recognition and fingerprint acquisition module includes a wet and dry finger recognition unit. The wet and dry finger recognition unit is used to set a push button with a water-absorbing film in the fingerprint collection area and set a water-absorbing ring on the outer circle of the push button; by pressing the push button and observing whether the water-absorbing ring absorbs water, it is determined whether the user's finger is dry or wet.

[0066] The wet and dry finger identification and fingerprint acquisition module includes a fingerprint acquisition unit, which is used to collect the fingerprint of the wrinkled and raised part of the wet finger to obtain the user's hand fingerprint. At this time, the user's hand fingerprint is specifically a wet hand fingerprint.

[0067] The fingerprint unlocking module is specifically used to match the obtained wet hand fingerprint with the pre-stored fingerprint to obtain a second matching degree. When the second matching degree is higher than or equal to the fingerprint unlocking threshold of the wet fingerprint unlocking mode, the missing fingerprints that are not matched in the pre-stored fingerprints are automatically filled in the wet hand fingerprint, and the terminal is unlocked according to the filled wet hand fingerprint.

[0068] The present invention proposes a button-type fingerprint unlocking system, which can set the percentage of the unlocking threshold according to the wrinkle degree of wet hands, and achieve the purpose of successful unlocking by appropriately reducing the security level. The unlocking is convenient and efficient.

[0069] Example 3:

[0070] The present invention provides a computer readable storage medium, such as Figure 5 As shown, the computer-readable storage medium includes a memory and a computer program stored in the memory. When the computer program is executed by the processor, the following key-type fingerprint unlocking method is implemented:

[0071] Step 1: Configure a dry fingerprint unlocking mode and a wet fingerprint unlocking mode, and set corresponding fingerprint unlocking thresholds for the dry fingerprint unlocking mode and the wet fingerprint unlocking mode respectively; wherein the fingerprint unlocking threshold of the wet fingerprint unlocking mode is lower than the fingerprint unlocking threshold of the dry fingerprint unlocking mode.

[0072] Set the corresponding fingerprint unlocking thresholds for the dry fingerprint unlocking mode and the wet fingerprint unlocking mode respectively. Specifically, set the fingerprint unlocking thresholds for the dry fingerprint unlocking mode and the wet fingerprint unlocking mode by pulling the setting slider;

[0073] Specifically, the fingerprint unlocking threshold of the dry fingerprint unlocking mode is set by pulling the setting slider to 100%; the fingerprint unlocking threshold of the wet fingerprint unlocking mode is set by pulling the setting slider to a percentage that matches the wrinkle degree of wet hand fingerprints.

[0074] Step two, judging whether the user's finger is dry or wet by pressing the key, and obtaining the user's fingerprint.

[0075] Judging whether the user's finger is dry or wet by pressing the key, specifically, setting a press key with a water-absorbing film in the fingerprint collection area, and setting a water-absorbing ring outside the press key; judging whether the user's finger is dry or wet by pressing the press key and whether the water-absorbing ring absorbs water. When the user's finger is wet, obtaining the user's fingerprint specifically refers to collecting the fingerprint of the raised part of the wet finger wrinkle, obtaining the user's fingerprint, and at this time the user's fingerprint is specifically a wet finger fingerprint.

[0076] Step three, according to the user's fingerprint, unlocking the terminal by fingerprint;

[0077] If the user's finger is dry, the dry fingerprint unlocking mode is automatically enabled, and the obtained user's fingerprint is matched with the pre-stored fingerprint to obtain a first matching degree; when the first matching degree is higher than or equal to the fingerprint unlocking threshold of the dry fingerprint unlocking mode, the terminal is unlocked; when the first matching degree is lower than the fingerprint unlocking threshold of the dry fingerprint unlocking mode, the terminal cannot be unlocked.

[0078] If the user's finger is wet, the wet fingerprint unlocking mode is automatically enabled, and the obtained user's fingerprint is matched with the pre-stored fingerprint to obtain a second matching degree; when the second matching degree is higher than or equal to the fingerprint unlocking threshold of the wet fingerprint unlocking mode, the terminal is unlocked; when the second matching degree is lower than the fingerprint unlocking threshold of the wet fingerprint unlocking mode, the terminal cannot be unlocked.

[0079] When the user's finger is wet, the process of unlocking the terminal is specifically that the obtained wet fingerprint is matched with the pre-stored fingerprint to obtain a second matching degree, when the second matching degree is higher than or equal to the fingerprint unlocking threshold of the wet fingerprint unlocking mode, the missing fingerprint that does not match in the pre-stored fingerprint is automatically filled in the wet fingerprint, and the terminal is unlocked according to the filled wet fingerprint.

[0080] The memory in the present invention can be an internal storage unit of the terminal, such as a hard disk or memory. The memory can also be an external storage device of the terminal, such as a plug-in hard disk equipped on the compass calibration terminal, a smart memory card (SmartMedia Card, SMC), a secure digital (Secure Digital, SD) card, a flash card (Flash Card), etc. Furthermore, the memory can also include both the internal storage unit of the compass calibration terminal and an external storage device. The memory is used to store computer programs and other programs and data required by the compass calibration terminal. The memory can also be used to temporarily store data that has been output or is to be output.

[0081] The present invention proposes a computer-readable storage medium, which can set the percentage of the unlocking threshold according to the wrinkle degree of wet hands, and achieve the purpose of successful unlocking by appropriately reducing the security level. The unlocking is convenient and efficient.

[0082] Example 4:

[0083] The present invention provides a terminal, such as Figure 6 As shown, the terminal includes a processor and the computer-readable storage medium as described above. When the processor executes the computer program on the computer-readable storage medium, the following key-type fingerprint unlocking method is implemented:

[0084] Step 1: Configure a dry fingerprint unlocking mode and a wet fingerprint unlocking mode, and set corresponding fingerprint unlocking thresholds for the dry fingerprint unlocking mode and the wet fingerprint unlocking mode respectively; wherein the fingerprint unlocking threshold of the wet fingerprint unlocking mode is lower than the fingerprint unlocking threshold of the dry fingerprint unlocking mode.

[0085] Set the corresponding fingerprint unlocking thresholds for the dry fingerprint unlocking mode and the wet fingerprint unlocking mode respectively. Specifically, set the fingerprint unlocking thresholds for the dry fingerprint unlocking mode and the wet fingerprint unlocking mode by pulling the setting slider;

[0086] Specifically, the fingerprint unlocking threshold of the dry fingerprint unlocking mode is set by pulling the setting slider to 100%; the fingerprint unlocking threshold of the wet fingerprint unlocking mode is set by pulling the setting slider to a percentage that matches the wrinkle degree of wet hand fingerprints.

[0087] Step 2: Determine whether the user's finger is dry or wet by pressing a key, and obtain the user's fingerprint.

[0088] Determining whether a user's finger is dry or wet by pressing a key involves placing a key with a water-absorbing film in the fingerprint collection area and a water-absorbing ring around the outer ring of the key. The key is pressed, and the determination of whether the water-absorbing ring absorbs water is made. If the user's finger is wet, the user's fingerprint is obtained by collecting a fingerprint from the wrinkled and raised area of ​​the wet finger. In this case, the user's fingerprint is specifically a wet fingerprint.

[0089] Step 3: Unlock the terminal using the user's fingerprint.

[0090] If the user's finger is a dry finger, the dry fingerprint unlocking mode is automatically enabled, and the acquired user fingerprint is matched with the pre-stored fingerprint to obtain a first matching degree; when the first matching degree is higher than or equal to the fingerprint unlocking threshold of the dry fingerprint unlocking mode, the terminal is unlocked; when the first matching degree is lower than the fingerprint unlocking threshold of the dry fingerprint unlocking mode, the terminal cannot be unlocked;

[0091] If the user's finger is wet, the wet fingerprint unlocking mode is automatically enabled, and the acquired user fingerprint is matched with the pre-stored fingerprint to obtain a second matching degree; when the second matching degree is higher than or equal to the fingerprint unlocking threshold of the wet fingerprint unlocking mode, the terminal is unlocked; when the second matching degree is lower than the fingerprint unlocking threshold of the wet fingerprint unlocking mode, the terminal cannot be unlocked.

[0092] When the user's fingers are wet, the process of unlocking the terminal is specifically as follows: matching the obtained wet hand fingerprint with the pre-stored fingerprint to obtain a second matching degree; when the second matching degree is higher than or equal to the fingerprint unlocking threshold of the wet fingerprint unlocking mode, automatically filling in the missing fingerprints that are not matched in the pre-stored fingerprints with the wet hand fingerprint, and unlocking the terminal based on the filled wet hand fingerprint.

[0093] The processor in the present invention may be a central processing unit (CPU), or other general-purpose processors, digital signal processors (DSP), application-specific integrated circuits (ASIC), field-programmable gate arrays (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor may be a microprocessor or any conventional processor, etc.

The touch-sensitive fingerprint unlocking method according to claim 4, characterized in that: When the user's finger is wet, the process of unlocking the terminal is as follows: The obtained wet hand fingerprint is matched with the pre-stored fingerprint to obtain a second matching degree. When the second matching degree is higher than or equal to the fingerprint unlocking threshold of the wet fingerprint unlocking mode, the missing fingerprints that are not matched in the pre-stored fingerprints are automatically filled in the wet hand fingerprint, and the terminal is unlocked according to the filled wet hand fingerprint.

6. The touch-sensitive fingerprint unlocking method according to any one of claims 1 to 3, characterized in that: If the user's finger is a dry fingerprint, the dry fingerprint unlocking mode is automatically enabled, and the acquired user fingerprint is matched with the pre-stored fingerprint to obtain a first matching degree; when the first matching degree is lower than the fingerprint unlocking threshold of the dry fingerprint unlocking mode, the terminal cannot be unlocked; If the user's finger is wet, the wet fingerprint unlocking mode is automatically enabled, and the acquired user fingerprint is matched with the pre-stored fingerprint to obtain a second matching degree; when the second matching degree is lower than the fingerprint unlocking threshold of the wet fingerprint unlocking mode, the terminal cannot be unlocked.

7. A touch-sensitive fingerprint unlocking system, characterized by: Includes the following modules, An unlocking threshold setting module, which is used to configure a dry fingerprint unlocking mode and a wet fingerprint unlocking mode, and set corresponding fingerprint unlocking thresholds for the dry fingerprint unlocking mode and the wet fingerprint unlocking mode respectively; wherein the fingerprint unlocking threshold of the wet fingerprint unlocking mode is lower than the fingerprint unlocking threshold of the dry fingerprint unlocking mode; A dry and wet finger recognition and fingerprint acquisition module, which is used to determine whether the user's finger is dry or wet by pressing a key and obtain the user's fingerprint; Fingerprint unlocking module, which is used to, If the user's finger is a dry fingerprint, the dry fingerprint unlocking mode is automatically enabled, and the acquired user fingerprint is matched with the pre-stored fingerprint to obtain a first matching degree; when the first matching degree is higher than or equal to the fingerprint unlocking threshold of the dry fingerprint unlocking mode, the terminal is unlocked; If the user's finger is wet, the wet fingerprint unlocking mode is automatically enabled, and the acquired user fingerprint is matched with the pre-stored fingerprint to obtain a second matching degree; when the second matching degree is higher than or equal to the fingerprint unlocking threshold of the wet fingerprint unlocking mode, the terminal is unlocked; The dry and wet finger recognition and fingerprint acquisition module includes a dry and wet finger recognition unit. The dry and wet finger recognition unit is used to set a push button with a water-absorbing film in the fingerprint collection area and set a water-absorbing ring on the outer ring of the push button; the push button surface is provided with a water-absorbing film; by pressing the push button and observing whether the water-absorbing ring absorbs water, it is determined whether the user's finger is dry or wet. When a finger presses a key, a certain amount of pressure is required to press it. This pressure presses the moisture on the finger to the water-absorbing film, and then the water-absorbing film guides the moisture to the water-absorbing ring at the edge, allowing the water-absorbing ring to absorb the moisture. Whether the water-absorbing ring absorbs water is used to determine whether the user's finger is dry or wet.

8. A computer-readable storage medium, characterized in that: The invention comprises a memory and a computer program stored in the memory, wherein when the computer program is executed by a processor, the touch-button fingerprint unlocking method according to any one of claims 1 to 6 is implemented.
