With the rapid development of information technology, the use of terminals (such as mobile phones, tablet computers, etc.) is becoming more and more popular. As the standard technology on the terminal, fingerprint recognition technology is widely used in the functions of unlocking, awakening and mobile payment of the terminal. In particular, the fingerprint payment function can not only solve the problem that the digital password is easily stolen in the prior art, but also input faster. During the fingerprint identification process, the successful fingerprint authentication triggers the business behavior after the authentication is successful. For a malicious virus webpage where the user cannot judge its security, it is easy to perform fingerprint verification due to personal unintentional or forced guidance or misleading, resulting in unnecessary The safety of the terminal is low due to personal safety information leakage or property loss. In order to solve these technical problems, the embodiments of the present application provide a fingerprint authentication method, device, device and storage medium.

Before introducing the embodiments of the present application, the following briefly introduces the implementation scenarios of the embodiments of the present application:

Scenario example 1:

The terminal displays a malicious virus webpage. The front-end program of the webpage is a payment page. At this time, it is waiting to verify the user's fingerprint. However, the payment page is disguised as other display forms, and the user cannot perceive that this page is a payment page, and the page does not provide an exit button. At this time, the habitual behavior of the user is to press the home button to exit the page, but when the user clicks the home button with the registered fingerprint finger, the fingerprint information authentication succeeds, which in turn triggers the payment behavior after the fingerprint authentication succeeds, causing unnecessary property loss .

Scenario example 2:

The terminal displays a malicious virus webpage. The front-end program of the webpage is a payment page, and there is no exit button. It is waiting to verify the user's fingerprint. The page is not disguised as other forms. The user quits the page by pressing the Home button in anxiety, but when the user clicks the Home button with a registered fingerprint finger, the fingerprint information verification is successful, which in turn triggers the payment behavior after successful fingerprint authentication, resulting in User unnecessary property loss.

In the above example application scenarios, or other similar application scenarios, such as other scenarios that require user fingerprint authentication, which leads to the leakage of user private information, the successful payment of fingerprint authentication triggers payment after successful fingerprint authentication, which in turn causes users Unnecessary losses. In order to solve the above problems, this application provides a fingerprint authentication method, device, equipment, and storage medium.

Based on the above application scenarios, the following describes in detail the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems in specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

Example one

FIG. 1 is a schematic flowchart of a fingerprint authentication method provided by an embodiment of the present application. As shown in FIG. 1, this embodiment is illustrated by applying the method to a terminal. The terminal may be a mobile phone, a digital broadcasting terminal, and a message receiving and sending device. , Game consoles, tablet devices, medical devices, fitness equipment, personal digital assistants, etc., the method includes the following steps:

Step S11: Obtain the user fingerprint information through the target button, and authenticate the acquired fingerprint information.

Step S12: If the fingerprint information authentication is successful and the first user operation on the target button is obtained, the business behavior after the fingerprint information authentication is successful is not triggered.

The step S11 will be explained:

In the process of acquiring the user's fingerprint information through the target button, the target button may be a physical button such as a Home button, a return button, and a confirmation button. At the same time, the target button may also be a virtual button, such as a floating ball, etc. There are no restrictions on the specific buttons and button forms, as long as the user's fingerprint information can be obtained through the target button. Optionally, the target key is any of the Home key, Back key, or Confirm key.

The user's fingerprint information is obtained through the user's related operation on the target button, where the user's related operation on the target button may be the user's touch operation on the target button, and the user feeds back the user's fingerprint information to the micro control unit in the terminal device through the related operation , The terminal recognizes and authenticates the user's fingerprint information. Fingerprint recognition refers to the identification by comparing the detailed feature points of different fingerprints. Fingerprint recognition technology involves image processing, pattern recognition, computer vision, mathematical morphology, wavelet analysis and many other disciplines. Since each person's fingerprint is different, and there are obvious differences between the same person's ten fingers, the fingerprint can be used for identification. The embodiment of the present application does not limit the specific method of fingerprint identification, as long as it can identify the user's fingerprint information.

In a possible implementation manner, obtaining the user fingerprint information through the target button and authenticating the obtained fingerprint information includes: obtaining a legal user fingerprint template; matching the user fingerprint information with the fingerprint template.

Before performing fingerprint authentication, the user also needs to obtain a legal user fingerprint template. The legal user fingerprint template can be obtained by touching the user's fingerprint in the terminal to the target button that can collect the user fingerprint template. For example, the user can obtain , Use the right index finger to touch the target button multiple times, and register the preset fingerprint information of the user by repeatedly inputting the user fingerprint information, so as to obtain a legal user fingerprint template. The embodiment of the present application does not limit the specific method of acquiring the user fingerprint template. In addition, the embodiment of the present application also does not limit the fingers of the acquired user fingerprint template and the number of acquired user fingerprint templates, as long as the legal user fingerprint can be obtained Template.

After obtaining the user's fingerprint information through the user's related operation on the target button, the obtained fingerprint information also needs to be authenticated. Specifically, the user's fingerprint information and the user's fingerprint template can be matched, because there are bumps on the front skin of the finger end The uneven texture contains a lot of information. The patterns of these skins are different in patterns, breakpoints, and intersections, and they are called "features" in information processing, and these features are unique and permanent, and can correspond one person to their fingerprints one by one. . By matching the user fingerprint information with the user fingerprint template and judging the authentication result based on the similarity between the user fingerprint information and the user fingerprint template, if the user fingerprint information matches the user fingerprint template successfully, the user fingerprint information is successfully authenticated. If the fingerprint information and the user fingerprint template match fail, the user fingerprint information authentication fails. The embodiment of the present application does not make any limitation on the fingerprint information authentication method, as long as it can authenticate the acquired user fingerprint information.

Authentication of user fingerprint information can be achieved through the central processing unit (CPU) of the terminal device, or through the microcontroller unit (MCU) of the terminal device. The specific implementation method is not limited.

Step S12 will be explained:

After the authentication of the acquired user fingerprint information through step S11, the authentication result of the user fingerprint information may be that the authentication of the user fingerprint information is successful or the authentication of the user fingerprint information fails. If the authentication of the user fingerprint information fails, the fingerprint will not be triggered For the business behavior after the authentication is successful, if you need to continue to execute the business behavior after the fingerprint authentication is successful, you need to re-acquire the user fingerprint information and authenticate the acquired fingerprint information. The embodiments of this application do not do anything about the terminal behavior after the authentication fails limit.

If the fingerprint information authentication is successful, the first user operation on the target button needs to be obtained. In the case where the fingerprint information authentication is successful and the first user operation on the target button is obtained, the business behavior after the successful fingerprint information authentication is not triggered By further restricting the conditions that trigger the business behavior after the fingerprint information authentication is successful, it can effectively avoid subsequent business behaviors caused by user misoperation, etc., and improve the operability and security of the terminal. For example, in the above example scenario, on a malicious virus webpage, the front-end program of the webpage is a payment page, the payment page is in the form of a normal payment page or disguised as other display forms, waiting for user fingerprint information authentication, if the user uses If the finger touches or clicks the home button, the fingerprint information authentication succeeds, and the user can also operate through the first user without triggering the payment behavior after the fingerprint information authentication succeeds, thereby avoiding unnecessary property loss of the user. Wherein, acquiring the first user operation on the target key can be implemented by the MCU in the terminal device.

In order not to trigger the business behavior after the fingerprint information authentication is successful, in a possible implementation manner, if the fingerprint information authentication is successful and the first user operation on the target button is obtained, a prompt message is pushed to remind the user that the user cannot proceed Business behavior. Optionally, the business behavior is user payment behavior. The following describes an embodiment of the present invention by taking an example of prompting the user that payment cannot be performed. FIG. 2 is a schematic diagram of an operation interface provided by an embodiment of the present application. As shown in FIG. 2, during the payment process, the user ’s fingerprint information needs to be obtained. , The interface 201 indicates that the user's fingerprint information is obtained through the target button, and the obtained fingerprint information is successfully authenticated. If the user wants to prevent this payment behavior, the user can perform the first user operation on the target button, where the interface 202 indicates the acquisition To the first user operation on the target button, the terminal pushes a prompt message 212 to remind the user that the current payment behavior has been blocked.

If the fingerprint information authentication is successful, but the first user operation is not obtained, the business behavior after the fingerprint information authentication is successful is triggered. For example, in the case where normal Alipay payment requires fingerprint authentication, by acquiring the user fingerprint information and comparing the fingerprint information If the authentication is successful, and the operation of the first user is not obtained, Alipay makes a successful payment, which does not affect the business behavior after triggering the fingerprint information authentication under normal circumstances.

The first user operation may be a touch operation on the target key exceeding a preset duration, or a long press operation on the target key, etc. The embodiment of the present application does not specifically limit the operation of the first user, as long as the fingerprint authentication is successful and The first user operation can be acquired without triggering the business behavior after the fingerprint information authentication routine. Optionally, the first user operation is a pressing operation on the target key. After the fingerprint information authentication is successful, the user performs a pressing operation on the target key, and the business behavior after the fingerprint information authentication is successful is not triggered. For example: In the above example scenario, a malicious virus webpage, the front-end program of the webpage is a payment page, the payment page is in the form of a normal payment page or disguised as other display forms, waiting for the user's fingerprint information to be authenticated, although the user uses the registered fingerprint finger Touching the home button results in successful fingerprint information authentication, but the user can also press the home button to prevent the terminal from triggering payment after the fingerprint information authentication is successful, thereby avoiding unnecessary property loss for the user.

In a possible implementation manner, after the fingerprint information is successfully authenticated, in order to prevent the business behavior after triggering the successful fingerprint authentication, the first user operation may also be that the registered fingerprint finger touches the target key for more than a preset duration. For example, after the authentication of the obtained user fingerprint information is successful, the registered fingerprint finger touches the target button for more than a preset duration, and the business behavior after the successful fingerprint authentication is not triggered.

In the embodiment of the present application, since the embodiment of the present application can obtain the first user operation after the fingerprint information authentication is successful, the business behavior after the fingerprint information authentication is successful is not triggered, and whether the fingerprint information is successfully authenticated is achieved. Trigger the corresponding business behavior for manual control, which effectively avoids business behavior that violates the user's wishes due to misoperation, etc., thereby improving the security and reliability of the terminal.

Example 2

On the basis of the first embodiment described above, FIG. 3 is a schematic flowchart of a fingerprint authentication method provided by another embodiment of the present application. In this embodiment, the method is applied to a terminal for illustration. The terminal may be a mobile phone or a digital broadcasting terminal. , Messaging devices, game consoles, tablet devices, medical devices, fitness equipment, personal digital assistants, etc. As shown in Figure 3, the fingerprint authentication method provided in this application also includes:

Step S21: If the fingerprint information authentication is successful, and a second user operation on the target button is obtained, the business behavior after the fingerprint information authentication is successful is triggered.

After the authentication of the acquired user fingerprint information through step S11, if the fingerprint information authentication is successful, a second user operation on the target key needs to be acquired. In the case where the fingerprint information authentication is successful and the second user operation is acquired, trigger The business behavior after the fingerprint information authentication succeeds, by further restricting the conditions that trigger the business behavior after the fingerprint information authentication succeeds, it can effectively avoid subsequent business behaviors caused by user misoperation, etc., and improve the operability and security of the terminal . For example, in the case where normal Alipay payment requires fingerprint authentication, by acquiring the user's fingerprint information and authenticating the fingerprint information, and acquiring the second user operation on the target button, Alipay's payment is successful and does not affect the triggering of the normal case Business behavior after successful fingerprint information authentication. FIG. 4 is a schematic diagram of an operation interface provided by another embodiment of the present application. As shown in FIG. 4, for example, in the case where normal Alipay payment requires fingerprint authentication, the user ’s fingerprint information needs to be obtained and the fingerprint information is authenticated. Interface 401 shows The user's fingerprint information is obtained through the target button, and the obtained fingerprint information is successfully authenticated. In the case of normal payment, the user performs a second user operation on the terminal. The user interface 402 indicates that after the fingerprint information is successfully authenticated, the target The second user operation of the button triggers the payment behavior after the fingerprint information authentication is successful. After triggering the business behavior after the fingerprint information authentication is successful, the user may also be prompted to push the payment successfully through the push message 412.

The second user operation may be a touch operation on the target key, or may be a pressing operation on the target key, etc. The embodiment of the present application does not specifically limit the operation of the second user, as long as the fingerprint authentication is successful and the second The user operation can trigger the business behavior after the fingerprint information authentication routine. Optionally, the second user operation is an operation in which the user removes the finger from the target key. For example, in the case where normal Alipay payment requires fingerprint authentication, by acquiring the user's fingerprint information and authenticating the fingerprint information, and the user removes the finger from the target button, the Alipay payment is successful, which does not affect the fingerprint information authentication under normal circumstances Business behavior after success. Acquiring the second user operation on the target key can be implemented by the MCU in the terminal device.

The embodiments of the present application do not specifically limit the operation of the first user and the operation of the second user, as long as the terminal can perform corresponding non-trigger or trigger business operations after successful fingerprint authentication according to the first user operation or the second user operation.

In the embodiment of the present application, since the embodiment of the present application can obtain the operation of the second user after the fingerprint information authentication is successful, the business behavior after the fingerprint information authentication is successful is triggered, which effectively avoids the violation of the user due to misoperation and the like Willing business behavior, thereby improving the security and reliability of the terminal.
