Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a fingerprint information processing method and a user terminal, which are beneficial to improving the efficiency of fingerprint information verification. The following are detailed below.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a fingerprint information processing method according to an embodiment of the present invention. As shown in FIG. 1, the fingerprint information processing method can comprise 101-103 parts.
101. The first terminal detects a distance between a user's finger and a fingerprint input area of the first terminal.
In the embodiment of the present invention, the first terminal may include, but is not limited to, a user terminal having a fingerprint input area, such as a smart phone, a tablet computer, a notebook computer, and a desktop computer. The operating system of the user terminal may include, but is not limited to, an Android operating system, an IOS operating system, a Symbian operating system, a Black Berry operating system, a Windows operating system, and the like, and the embodiment of the present invention is not limited thereto. Wherein the fingerprint input area may be located in a Home key or other area of the touch screen or the first terminal. Alternatively, the first terminal may detect a distance between the user's finger and the fingerprint input area of the first terminal through a distance sensor.
As an alternative implementation, the specific implementation of the first terminal detecting the distance between the user's finger and the fingerprint input area of the first terminal may be:
the first terminal detects a distance between a user's finger, which is above a plane in which the fingerprint input area of the first terminal is located, and the fingerprint input area of the first terminal.
In this embodiment, the finger is above the plane of the fingerprint input area of the first terminal and not in the same plane as the fingerprint input area of the first terminal. In practical applications, when the distance from the user's finger above the plane of the fingerprint input area of the first terminal to the fingerprint input area is small, the user's finger is likely to input a fingerprint in the fingerprint input area. Thus, it is possible to predict whether the user intends to input a fingerprint at the fingerprint input area by detecting the distance between the user's finger, which is above the plane in which the fingerprint input area of the first terminal is located, and the fingerprint input area of the first terminal.
102. The first terminal judges whether the distance is smaller than a preset value.
In the embodiment of the invention, after the first terminal detects the distance between the finger of the user and the fingerprint input area of the first terminal, whether the distance is smaller than a preset value is judged. If the distance is smaller than the preset value, step 103 is executed. Optionally, if the distance is greater than or equal to the preset value, the distance between the finger of the first terminal and the fingerprint input area of the first terminal is continuously detected.
103. The first terminal sends a decryption request carrying the identification information to the second terminal.
In the embodiment of the present invention, the second terminal may be a wearable device, a smart phone, a tablet computer, a server, or the like, which is not limited in the embodiment of the present invention.
In the embodiment of the invention, the identification information is the identification of the first terminal or the identification of the user. The identifier of the first terminal is identity information of the first terminal, and the identifier of the user may be an application account. For example, if the first terminal and the second terminal interact through a certain application, the identifier of the user may be account information of the application.
In the embodiment of the present invention, the decryption request is used to request the second terminal to decrypt the stored fingerprint information corresponding to the identification information, so as to obtain decrypted fingerprint information.
In the embodiment of the invention, the first terminal verifies the fingerprint input by the user through the second terminal. The second terminal stores encrypted fingerprint information. After receiving the fingerprint information input by the user, the first terminal sends the fingerprint information to the second terminal. The second terminal can use the decrypted fingerprint information obtained before to verify the fingerprint information sent by the first terminal, namely the second terminal compares the fingerprint information sent by the first terminal with the decrypted fingerprint information and judges whether the fingerprint information and the decrypted fingerprint information are matched or not so as to verify the fingerprint information sent by the first terminal.
Therefore, by implementing the embodiment of the invention, the first terminal can predict whether the user needs to input the fingerprint for verification, so that the second terminal can decrypt the encrypted fingerprint information in advance. After the second terminal receives the fingerprint information sent by the first terminal, the fingerprint information sent by the first terminal can be verified by directly using the decrypted fingerprint information before the second terminal receives the fingerprint information sent by the first terminal, and the fingerprint information is not required to be decrypted when the fingerprint information sent by the first terminal is received, so that the time for decrypting the fingerprint information is saved, the time for verifying the fingerprint is further shortened, and the efficiency for verifying the fingerprint is improved.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating another fingerprint information processing method according to an embodiment of the present invention. As shown in FIG. 2, the fingerprint information processing method can comprise 201-209 parts.
201. The first terminal detects a distance between a user's finger and a fingerprint input area of the first terminal.
In the embodiment of the present invention, the specific implementation of the portion 201 can refer to the portion 101 shown in fig. 1, which is not described herein again.
202. The first terminal judges whether the distance is smaller than a preset value.
In the embodiment of the invention, after the first terminal detects the distance between the finger of the user and the fingerprint input area of the first terminal, whether the distance is smaller than a preset value is judged. If the distance is smaller than the preset value, step 203 is executed. Optionally, if the distance is greater than or equal to the preset value, the distance between the finger of the first terminal and the fingerprint input area of the first terminal is continuously detected.
203. The first terminal sends a decryption request carrying the identification information to the second terminal.
In the embodiment of the present invention, the identification information is an identification of the first terminal or an identification of the user, the decryption request is used to request the second terminal to decrypt the stored fingerprint information corresponding to the identification information, so as to obtain decrypted fingerprint information, and the decrypted fingerprint information is used to verify the fingerprint information sent by the first terminal.
204. And if the fingerprint information input by the user through the fingerprint input area is not received within the preset time period, the first terminal sends a deleting instruction for instructing the second terminal to delete the decrypted fingerprint information to the second terminal.
In the embodiment of the invention, after the first terminal sends the decryption request carrying the identification information to the second terminal, the time when the first terminal finishes sending the decryption request to the second terminal is taken as the starting time, and whether the fingerprint information input by a user through the fingerprint input area in the preset time period is detected. And if the fingerprint information input by the user through the fingerprint input area is not detected within the preset time period, the first terminal sends a deleting instruction for instructing the second terminal to delete the decrypted fingerprint information to the second terminal.
The second terminal stores the encrypted fingerprint information in order to improve the security of the fingerprint information. After the second terminal decrypts the fingerprint information, if the decrypted fingerprint information is stored for a long time, the decrypted fingerprint information is easy to be unsafe. Therefore, if the user does not need to perform fingerprint verification through the second terminal for a long period of time, the second terminal can delete the decrypted fingerprint information to ensure the security of the fingerprint information.
205. The first terminal receives first fingerprint information input by a user through a fingerprint input area.
In this embodiment of the present invention, the first fingerprint information may be a fingerprint image or fingerprint feature information, and the embodiment of the present invention is not limited.

In the embodiment of the present invention, after receiving the verification request, the second terminal verifies whether the first fingerprint information matches with the decrypted fingerprint information obtained before. And if so, sending the first response information to the first terminal. If not, optionally, the second terminal sends, to the first terminal, second response information for indicating that the first fingerprint information check fails.
207. The first terminal receives first response information which is sent by the second terminal and used for indicating that the first fingerprint information passes the verification.
208. The first terminal performs a target operation.
In the embodiment of the invention, if the first terminal receives the first response message, the first terminal executes the target operation. The target operation comprises any one or combination of more of a payment operation, a screen unlocking operation, an application login operation and an application unlocking operation.
By executing the parts 205-208, the first terminal can enable the second terminal to verify the fingerprint information sent by the first terminal by using the decrypted fingerprint information, thereby improving the efficiency of fingerprint verification. And the corresponding operation is executed after the fingerprint verification is successful, so that the safety of the first terminal is improved.
209. And the first terminal sends a deleting instruction for instructing the second terminal to delete the decrypted fingerprint information to the second terminal.
In the embodiment of the invention, after receiving the first response message, the first terminal sends a deletion instruction for instructing the second terminal to delete the decrypted fingerprint information to the second terminal. So that the second terminal can delete the decrypted fingerprint information in time to ensure the safety of the fingerprint information.
As an optional implementation, the first terminal may further perform the following operations:
when detecting that the first terminal is in a screen locking state, establishing connection between the first terminal and the second terminal; or when the first terminal enters an interface which needs the user to input the fingerprint information for verification, the first terminal is connected with the second terminal.
For example, when the target operation includes a screen unlocking operation, the first terminal establishes a connection with the second terminal when detecting that the first terminal is in a screen locking state. When the target operation comprises a payment operation, an application login operation or an application unlocking operation, when the first terminal enters an interface which needs a user to input fingerprint information for verification, the first terminal is connected with the second terminal.
By implementing the implementation mode, the first terminal can be connected with the second terminal in advance, and the first terminal does not need to be connected with the second terminal when the fact that the distance between the finger of the user and the fingerprint input area of the first terminal is smaller than the preset value is detected, so that the time for decrypting the fingerprint information is favorably shortened, and the efficiency of fingerprint verification is favorably improved.
As an optional implementation manner, when the target operation includes a screen unlocking operation, a specific implementation manner of the first terminal detecting a distance between the user finger and the fingerprint input area of the first terminal may be:
