Description
Technical Field
The present invention relates to fingerprint processing technologies, and in particular, to a fingerprint event processing apparatus and method.
Background
With the development of network information, information security is more and more emphasized by people. In order to secure Personal electronic information, most users set password authentication for registration of a Personal Computer PC (Personal Computer, hereinafter, referred to as "PC").
However, password authentication needs to rely on the memory of a user, and if a simpler password is set, the password is easy to crack; setting too complicated password is not good for memory and user experience is not friendly. In recent years, biometric identification technology is more and more widely applied, especially fingerprint identification technology, which has uniqueness and convenience and is widely applied to the fields of fingerprint payment, fingerprint unlocking, fingerprint identity verification and the like. Therefore, in order to make the login of the PC more secure and convenient, many manufacturers add a fingerprint function to the PC. However, the existing fingerprint collection module and the power key are independently arranged (separately arranged) on the PC, so that when the user starts the PC, the user can complete the function of security verification by touching the fingerprint collection module after waiting for the start of the operating system of the PC, and the efficiency is not high. If encapsulate the shape of power button with fingerprint collection module, install the power button in fingerprint collection module's below, the power button unites two into one then has promoted the outward appearance aesthetic feeling with the fingerprint, can make fingerprint collection module and button function close into a whole simultaneously. The user can finish fingerprint image acquisition simultaneously only by normally pressing the power supply key, so that the starting and safety verification processes are accelerated, and the user experience is greatly improved.
Although the above-mentioned scheme of integrating fingerprint collection module and power button speeds up the efficiency of fingerprint verification, because the power button can be touched by mistake in the user fingerprint operation process, the misoperation response of the PC system to the power button is caused, for example, in the fingerprint registration process or in the process of unlocking the PC by the user in the screen locking state, the user touches the fingerprint collection module and mistakenly presses the power button to cause the PC system to be dormant or shut down, thereby affecting the normal use of the PC by the user.
Therefore, when the power key and the fingerprint collection module are integrated, how to effectively match the cooperative work of the power key and the fingerprint collection module needs to be considered, so that the fingerprint verification function of the fingerprint collection module and the power event response function of the power key can not interfere with each other.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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, but 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.
Fig. 1 is a schematic structural diagram of a fingerprint event processing apparatus according to an exemplary embodiment of the present invention, and as shown in fig. 1, the fingerprint event processing apparatus may be disposed in an electronic device that has a fingerprint application requirement, for example, an electronic device such as a desktop PC, a notebook computer, a PAD (PAD for a tablet computer), or a mobile phone. The fingerprint event processing apparatus of this embodiment specifically includes:
a control module 1 and a fingerprint power supply unit 2; the fingerprint power supply unit 2 comprises a fingerprint acquisition module 21 and a power supply key 22;
the control module 1 is configured to receive a fingerprint trigger instruction and a power event trigger instruction generated when the fingerprint power Unit 2 is pressed, report fingerprint data carried by the fingerprint trigger instruction to a Central Processing Unit CPU (Central Processing Unit, CPU for short) 3, and determine whether to report a power event corresponding to the power event trigger instruction to the CPU according to a pressing duration corresponding to the power event trigger instruction.
Specifically, the control module 1 is connected to the CPU3 and the fingerprint power supply unit 2, and the fingerprint collection module 21 and the power key 22 are integrally formed into the fingerprint power supply unit 2, wherein the fingerprint collection module 21 may be packaged into the shape of the power key 22, and the power key 22 is installed below the fingerprint collection module 21. The fingerprint collecting module 21 disposed on the upper portion is used for collecting fingerprint information of a user by contacting with a finger of the user, and the power key 22 disposed on the lower portion is used for sensing a pressing operation of the user on the power key 22. Therefore, when the user touches the fingerprint acquisition module 21 to enter fingerprint information, and possibly presses the power key 22 below the fingerprint acquisition module 21, the CPU3 may interrupt the ongoing fingerprint event due to the response to the power key 22, which may affect the normal operation of the electronic device by the user. In this embodiment, for such a situation of the power key 22 being operated by mistake, the following scheme is adopted, in which the fingerprint acquisition module 21 and the power key 22 are both connected to the control module 1, and when the fingerprint power unit 2 is pressed, the control module 1 receives a fingerprint trigger instruction generated by the fingerprint acquisition module 21, and also receives a power event trigger instruction generated by the power key 22. Although the power button 22 generates the power event trigger command, the control module 1 needs to determine the validity of the power event trigger command to determine whether to report the power event to the CPU 3. Specifically, whether the power event corresponding to the power event trigger instruction is reported to the CPU may be determined according to the pressing duration corresponding to the power event trigger instruction. Thereby avoiding a response to the user operating the power key 22 by mistake. Meanwhile, the fingerprint acquisition module 21 is configured to acquire fingerprint information of a user, form a fingerprint trigger instruction with the acquired fingerprint data, and send the fingerprint trigger instruction to the control module 1; the control module 1 reports the fingerprint data carried by the fingerprint trigger instruction to the CPU3, so that the CPU3 processes the fingerprint data and responds to the fingerprint event.
The fingerprint event processing device of the embodiment comprises: the fingerprint power supply unit comprises a fingerprint acquisition module and a power supply key; the control module is used for receiving a fingerprint trigger instruction and a power event trigger instruction which are generated when the fingerprint power supply unit is pressed, reporting fingerprint data carried by the fingerprint trigger instruction to a Central Processing Unit (CPU), and determining whether to report a power event corresponding to the power event trigger instruction to the CPU according to the pressing duration corresponding to the power event trigger instruction. The accurate identification of the power supply event triggered by the power supply key is realized, so that under the condition that the fingerprint acquisition module and the power supply key are pressed together, respective functions can be accurately distinguished and responded, misoperation of the power supply key by a user is effectively avoided, and the user experience is improved.
As shown in fig. 1, on the basis of the previous embodiment, the fingerprint event processing apparatus of this embodiment is further configured to implement the following specific functions:
optionally, a set threshold for determining the pressing duration corresponding to the power event trigger instruction may be stored in the control module 1, and then, in a possible case after the control module 1 determines the pressing duration,
the pressing duration is smaller than the set threshold, in which case the control module 1 is specifically configured to mask the power event when the pressing duration is smaller than the set threshold. That is, if the duration that the user presses the power key 21 is less than the duration of the set threshold, the control module 1 determines that the current pressing operation is a user's misoperation, and shields the power event corresponding to the power event trigger instruction and does not report the power event to the CPU3, so that the CPU3 does not receive the power event and naturally does not respond to the user pressing the power key 21.
In this case, the CPU3 receives only the fingerprint data transmitted to it by the control module 1 without interference from a power event of a malfunction, and the CPU3 may perform a fingerprint registration saving operation based on the fingerprint data reported from the control module 1 or a fingerprint matching verification operation based on the fingerprint data.
Another possible situation is that the pressing duration is greater than or equal to the set threshold, in which case the control module 1 is specifically configured to report the power event to the CPU3 when the pressing duration is greater than or equal to the set threshold. That is, the user presses the power button 22 for a longer period of time, determining that it is intended to trigger the power event, e.g., the power event is triggered to cause the electronic device to enter a sleep state from an active state. In this case, the control module 1 does not shield the power event corresponding to the power event trigger instruction, but reports the power event to the CPU3, so that the CPU3 responds to the power event. At this time, in order to ensure that the power event does not interrupt the operation of the fingerprint event, the CPU needs to complete the operation of the fingerprint event first and then respond to the power event, specifically, the CPU3 is configured to execute a fingerprint registration and storage operation according to the fingerprint data, or respond to the power event after executing a fingerprint matching and verification operation according to the fingerprint data.
For fingerprint matching verification operation, for example, in an application scenario, the electronic device may be in a screen locking state, where the screen locking state is that a screen of the electronic device is in a locked state, generally, for example, a Windows system is taken as an example, a number of shortcut keys of an operating system for locking a computer are Windows key + L, when the Windows key + L is triggered, the computer enters the locked state, at this time, a user cannot perform information interaction with the computer, the user needs to input a shortcut key Ctrl + Alt + Delete for unlocking the computer, and if the user performs password protection, an unlocking password is input to perform unlocking operation on the computer; if the electronic equipment starts fingerprint matching verification, the unlocking password and the user fingerprint are bound together, the user touches the fingerprint acquisition module 21 to input fingerprint data, and the fingerprint data is unlocked by the computer after being subjected to fingerprint verification by the CPU 3. In addition to the above fingerprint matching verification operation required when unlocking the electronic device, the application scenario may further include: and matching and verifying the fingerprint data to implement payment verification or identity verification and the like.
For example, in an application scenario, if a user needs to touch the fingerprint acquisition module 21 for a long time during fingerprint registration, the power key 22 may be pressed for a long time by mistake, at this time, if the control module 1 identifies that the pressing duration is greater than or equal to the set threshold, the power event is reported to the CPU3, but at this time, fingerprint registration is still in progress, if the CPU3 receives the reported power event and then immediately responds, the electronic device enters a sleep state so that the fingerprint registration process is interrupted, and the user needs to wake up the system again to continue the previous registration operation. Therefore, for the scenario where the duration of the power key 22 is longer than or equal to the predetermined threshold, the CPU3 needs to determine whether the fingerprint data processing is completed, that is, the CPU3 is configured to perform the fingerprint registration saving operation according to the fingerprint data, or to respond to the power event after performing the fingerprint matching verification operation according to the fingerprint data. After the response of the electronic equipment to the fingerprint event is finished, the electronic equipment is set to be in a sleep state, so that the processing of the fingerprint event is not influenced. Thereby further improving the cooperative working performance of the fingerprint acquisition module 21 and the power key 22 which are integrally arranged.
Optionally, the control module 1 is further configured to receive a fingerprint service activation instruction sent by the CPU3 before receiving a fingerprint trigger instruction and a power event trigger instruction generated when the fingerprint power unit 2 is pressed.
Specifically, the CPU3 may have a driver installed therein for driving the fingerprint acquisition module 21 to acquire fingerprint data, where the driver monitors the progress of the electronic device, and determines whether the electronic device has a requirement for fingerprint operation, for example, whether the current system is in a fingerprint function activation state such as fingerprint registration or screen locking, and if the system is in the fingerprint function activation state, the CPU3 sends a fingerprint service activation instruction to the control module 1, so that the control module 1 configures the fingerprint acquisition module 21 after receiving the fingerprint service activation instruction, so as to acquire fingerprint data of a user, thereby forming the fingerprint trigger instruction. According to the scheme, the fingerprint acquisition module 21 acquires the user fingerprint only when the control module 1 receives the fingerprint service activation instruction through the fingerprint service activation instruction, and if the control module 1 does not receive the fingerprint service activation instruction, the fingerprint acquisition module does not acquire the user fingerprint, so that the respective enabling states of the fingerprint acquisition module 21 and the power key 22 are further distinguished. That is, if the system is not in the fingerprint function activated state, the control module 1 can only receive the power event trigger instruction generated when the power key 22 is pressed, but is not interfered by the fingerprint trigger instruction, and at this time, the CPU3 may respond to the power key according to the condition that the original fingerprint collection module is separated from the power key. If the system is in the fingerprint function activation state, two situations exist, namely that the user touches the fingerprint acquisition module 21 without pressing the power key 22 and the user touches the fingerprint acquisition module 21 while pressing the power key 22, and if the user touches the fingerprint acquisition module 21 without pressing the power key 22, the control module 1 only reports the fingerprint data of the CPU 3; if the user touches the fingerprint acquisition module 21 and presses the power key 22 at the same time, the control module 1 executes the aforementioned step of determining whether to report the power event according to the pressed duration of the power key 22, which is not described herein again.
Further, based on the above embodiments, the control module 1 may have two specific implementation manners, as shown in fig. 2a, the control module 1 may be a micro control Unit MCU (MCU for short) 11; the MCU11 is respectively connected with the fingerprint acquisition module 21 and the power key 22, and the MCU11 is also connected with the CPU 3.
Specifically, the power key 22 is connected to an Input pin of a General Purpose Input/Output GPIO (GPIO for short) of the MCU11, and an Output pin of the General Purpose Input/Output GPIO of the MCU11 is connected to the CPU3, so as to report a power event triggered by the power key 22 to the CPU 3; the fingerprint acquisition module 21 is connected to an input pin of a Serial Peripheral Interface SPI (short for "SPI") of the MCU11, and an output pin of the SPI of the MCU11 is connected to the CPU3, so as to report fingerprint data carried by a fingerprint trigger instruction triggered by the fingerprint acquisition module 21 to the CPU 3. Optionally, the fingerprint data between the MCU11 and the CPU3 may also be transmitted through a Universal Serial Bus (USB) interface.
As shown in fig. 2b, another embodiment is that the control module 1 is composed of an embedded control module EC (abbreviated as "EC") and an MCU; in particular to a method for preparing a high-performance nano-silver alloy,
the control module 1 comprises an embedded control module EC12 and a micro control unit MCU 11;
the EC12 is connected with the power key 22, and the MCU11 is connected with the fingerprint acquisition module 21;
the CPU3 is respectively connected with the EC12 and the MCU 11;
the EC12 is configured to receive a power event trigger instruction generated when the fingerprint power unit 2 is pressed, and determine whether to report a power event corresponding to the power event trigger instruction to the CPU3 according to a pressing duration corresponding to the power event trigger instruction;
the MCU11 is used for receiving a fingerprint trigger instruction generated when the fingerprint power supply unit 2 is pressed and reporting the fingerprint data to the CPU 3.
Specifically, an EC12 chip is usually present in the electronic device, and the EC12 can control the power key 22 and also can control the power supplies of other power utilization modules on the motherboard, so that the EC12 and the MCU11 are used together to realize that the control module 1 has little change on the existing circuit structure, and is easy to implement.
Optionally, EC12, is further configured to mask power events when the length of the press is less than a set threshold.
Optionally, the EC12 is specifically configured to report the power event to the CPU3 when the pressing duration is greater than or equal to the set threshold.
Optionally, the MCU11 is further connected to the EC12, and configured to send a power mask start instruction to the EC after receiving the fingerprint service activation instruction sent by the CPU 3;
the EC12 is configured to, after receiving the power mask start instruction, execute an operation of determining whether to report a power event corresponding to the power event trigger instruction to the CPU3 according to a pressing duration corresponding to the power event trigger instruction.
Specifically, as described in the foregoing embodiment, the CPU3 sends the fingerprint service activation instruction to the MCU11, the MCU11 configures the fingerprint acquisition module 21 for fingerprint acquisition according to the instruction, and sends a power mask start instruction to the EC12 according to the fingerprint service activation instruction, so as to prompt the EC12 to determine the time length for which the received power key 22 is pressed, so as to determine whether to report a power event. If the MCU11 does not receive the fingerprint service activation instruction, which means that the system does not have a fingerprint event to be processed, the MCU11 does not acquire fingerprint data of the user, and the EC12 does not need to start power shielding, and it can report the power event to the CPU3 according to the processing method of the power key 22 in the prior art, and there is no fingerprint trigger instruction at this time. However, if the MCU11 receives the fingerprint service activation command, which means that the fingerprint function of the system is activated, the CPU3 notifies the MCU11 to configure the fingerprint acquisition module 21 to acquire the fingerprint data of the user, and at the same time, the MCU11 notifies the EC12 to start the power mask, so as to determine the pressed duration of the power key 22.
In the scheme of fig. 2a, only the MCU11 is used as the control module 1, so that the circuit structure of the fingerprint event processing apparatus is simplified, and the size of the circuit board is effectively reduced. The scheme of fig. 2b adopts MCU11 and EC12 as control module 1, where EC is a chip on the motherboard of the electronic device in the prior art, and the circuit modification is small and easy to implement. It should be noted that the implementation manners of the two control modules 1 are only for illustration and are not limiting to the embodiment of the present application.
