In a possible embodiment, the third control signal and the first control signal may be issued simultaneously by the first module 10, or the third control signal may be issued before the first control signal is issued.
Assuming that the second module 20 performs the fingerprint collection based on the optical fingerprint, since the optical fingerprint needs to generate a highlight background image in the fingerprint collection area, and the finger is illuminated with a strong light to generate a sufficient light flux, in the case that the first module 10 determines that the type of the trigger signal is the first authentication signal, the first module 10 may send out a control signal (including a third control signal, a second control signal, and a first control signal) to control the fourth module 40 to activate the fingerprint collection area, wake up the third module 30, and control the second module 20 to collect the fingerprint information in the fingerprint collection area.

the third module 30 is further configured to read the authentication identifier stored in the storage unit of the first module 10 to determine the authentication mode of the electronic device.
In a possible embodiment, the storage unit may include a register, for example, and the type of the trigger signal (i.e., the authentication mode) may be recorded in the register after the electronic device is successfully authenticated, for example, 0 may be used to indicate that the electronic device is authenticated in the first authentication mode, and 1 may be used to indicate that the electronic device is authenticated in the second authentication mode.
After the third module 30 is awakened or the electronic device is authenticated, the memory unit of the first module 10 can be read as required to determine the manner in which the electronic device is authenticated.

The second fingerprint identification algorithm may have a higher accuracy than the first fingerprint identification algorithm, e.g. when enhancing fingerprint information (e.g. a fingerprint image), the second fingerprint identification algorithm has a higher level of enhancement than the first fingerprint identification algorithm; in the feature extraction, the second fingerprint identification algorithm extracts more feature points than the first fingerprint identification algorithm.
That is, the first fingerprinting algorithm running in the second module 20 may be a simplified version of the second fingerprinting algorithm running in the third module 30, the first fingerprinting algorithm having a faster speed and lower power consumption than the second fingerprinting algorithm at the time of fingerprinting.
Of course, the present disclosure does not limit the specific implementation of the first fingerprint identification algorithm and the second fingerprint identification algorithm, and those skilled in the art can select them as needed.
In one example, applications may be classified in advance, for example, by security level.
The disclosure does not limit the specific classification manner, and in one example, the applications in the scene that needs payment may be classified into one class, and in the scene that needs payment, a trigger signal of the applications may be sent out, so as to control the second module 20 to acquire the second fingerprint information, and perform fingerprint identification on the second fingerprint information by using a second fingerprint identification algorithm, so as to perform identity authentication.

and controlling the electronic equipment to enter a master user system.
The third fingerprint identification algorithm may have a higher accuracy than the first fingerprint identification algorithm, e.g. the third fingerprint identification algorithm may have a higher level of enhancement than the first fingerprint identification algorithm when enhancing fingerprint information (e.g. a fingerprint image); in the feature extraction, the third fingerprint recognition algorithm extracts more feature points than the first fingerprint recognition algorithm.
That is, the first fingerprinting algorithm running in the second module 20 may be a simplified version of the third fingerprinting algorithm running in the third module 30, the first fingerprinting algorithm having a faster speed and lower power consumption than the third fingerprinting algorithm at the time of fingerprinting.
Of course, the present disclosure does not limit the specific implementation of the first fingerprint identification algorithm and the third fingerprint identification algorithm, and those skilled in the art can select them as needed.
Of course, in one example, the third fingerprinting algorithm may be the same as the second fingerprinting algorithm.
Through the mode, the electronic equipment can be authenticated in the first authentication mode or the second authentication mode according to the type of the trigger signal, and under the condition that the electronic equipment is authenticated in the first authentication mode, the fingerprint information is collected by the second module and is identified by the fingerprint identification algorithm which is simple in operation of the second module, and after the fingerprint information is successfully identified, the third module is controlled to authenticate the electronic equipment, so that the authentication speed can be increased, and the user experience can be improved.

As shown in fig. 4a, the time from the receipt of the trigger signal by the first module to the authentication of the third module is approximately 268 ms.
As shown in fig. 4b, when the first module determines that the second authentication mode is authentication (normal authentication), the first module directly wakes up the third module, after the third module is woken up, the third module controls the fourth module to activate the fingerprint acquisition area, the third module controls the second module to acquire fingerprint information, and when the third module obtains the fingerprint information, performs fingerprint identification according to the fingerprint information, determines whether the fingerprint information exists in the template data, and determines whether to authenticate the electronic device according to the identification result.
As shown in fig. 4b, the time from the receipt of the trigger signal by the first module to the authentication of the third module is about 453 ms.
Therefore, compared with a mode of authenticating the electronic equipment by using the related technology, the authentication device provided by the disclosure has a faster authentication speed, and can improve the user experience.
