As shown in fig. 1, fig. 1 is a schematic flow chart of an authentication method provided in the embodiment of the present application, which is applied to an electronic device, and the specific flow may be as follows:
101. a continuous frame structured light image of the head of the user is acquired with the structured light module.
In this embodiment, when the electronic device is turned on or unlocked, the structured light module is activated. The structured light module is used for emitting and shooting structured light, and the structured light is a set of projection light rays with known spatial directions and can comprise point structured light, line structured light, multi-line structured light, surface structured light and the like.
For example, the structured light module includes a structured light projector and a camera, and the step 101 may specifically include:
projecting the structured light outwards through the structured light projector and prompting a user to rotate the head;
and acquiring the structured light image projected by the head of the user within a preset time length through the camera to obtain a continuous frame structured light image.
In this embodiment, the structured light projector may be some type of projection device or instrument that projects a light spot, light slit, grating, grid, or speckle onto the head of a user. The preset time period may be set manually, for example, 10s in consideration of the rotational speed and the reaction time of the user.
102. It is determined whether the user is a living body based on the continuous frame structured light image, and if so, the following step 103 is executed, and if not, the execution returns to the step 101.
In this embodiment, in order to prevent a lawbreaker from being able to normally pass the biometric authentication even with the help of an inactive object such as a user photograph, a recorded voice, a copied fingerprint, etc., it may be determined whether the user is a living body before the authentication.
For example, the step 102 may specifically include:
and 1-1, generating corresponding three-dimensional coordinates of the head according to each frame of structured light image.
In the embodiment, the structured light is projected to the surface of the head of the user and then modulated by the height of the head, and the modulated structured light is collected by the camera and transmitted to the background for analysis and calculation to obtain the three-dimensional surface shape data of the head. The modulation mode can be divided into two categories of time modulation and space modulation, the most common method in the time modulation method is a flight time method, the flight time of the light pulse in the space is recorded by the method, the surface shape information of the head of a user is calculated through the flight time, the space modulation method is that the properties of the phase, the light intensity and the like of a structured light field are changed after being modulated by the height of the head, the three-dimensional surface shape information of the head can be obtained according to the change of the properties, and then the three-dimensional coordinates of each point on the head are obtained.
And 1-2, calculating the rotation angle according to the three-dimensional coordinates corresponding to any two frames of structured light images.
In this embodiment, considering that the variation range of the head center point is usually very small when the head of the person rotates, when the rotation angle is calculated, for any two frames of structured light images, the head center point of one frame of the structured light images can be used as the vertex of the included angle, and another representative other point (such as the nose tip or the mouth corner) is selected from each frame of the structured light images, and the corresponding rotation angle is obtained according to the included angle between the point and the vertex of the included angle in the two frames of the structured light images.
1-3, when the preset angle is included in the rotation angle, determining that the user is a living body.
In this embodiment, the preset angle may be set manually, and may be one or more angles, for example, considering that when the head of the person turns left or right, the head of the person usually rotates ninety degrees from the middle to the forward direction or the reverse direction, so that when the head of the user completes one unidirectional rotation, the rotation angle ranges from 0 ° to 90 °, and for this phenomenon, one or more angles may be selected as the preset angle, for example, the preset angle may include 30 °, 50 ° and 60 °.
103. And acquiring the digital password input by the user and the biological characteristic information of the user, wherein the biological characteristic information comprises at least one of fingerprint characteristics, voiceprint characteristics, face characteristics and iris characteristics.
In this embodiment, the numeric code may be manually input through a code interface, or may be input through voice. The user may be prompted to enter a digital password and to obtain user fingerprint characteristics via a fingerprint detector, and/or user voiceprint characteristics via a microphone, and/or user facial or iris characteristics via a camera
104. And generating a code to be verified according to the digital password and the biological characteristic information.
For example, the step 104 may specifically include:
acquiring a character string corresponding to the biological characteristic information;
combining and converting the character string and the digital password to obtain a converted character string;
and generating a corresponding two-dimensional code as a code to be verified according to the converted character string.
In this embodiment, the biometric information may be processed by using an MD5(Message Digest MD5, fifth edition) Algorithm to obtain a corresponding MD5 value (i.e. a character string), and in general, the calculated MD5 value is fixed for data of any length. The combination method can be set artificially, such as integral combination, that is, a character string (or a numeric code) is directly inserted into the back of a numeric code (or a character string) to form a long character string, or cross combination, that is, each character in the character string (or the numeric code) and each character in the numeric code (or the character string) are combined into a long character string in a cross insertion manner, and the like.
105. And performing identity authentication on the user according to the code to be authenticated.
For example, the step 105 may specifically include:
matching the code to be verified with a preset verification code;
if the matching is successful, determining that the user identity authentication is passed;
if the matching fails, accumulating the failure times, and determining the corresponding waiting time according to the failure times;
and returning to execute the operation of acquiring the digital password input by the user and the biological characteristic information of the user after the waiting time length is reached.
In this embodiment, the more the accumulated failure times, the higher the possibility that the user is an illegal user, so the accumulated failure times may be set in proportion to the waiting time, that is, the more the accumulated failure times, the longer the waiting time for inputting the password and acquiring the biometric information next time, thereby prolonging the time for the illegal user to break the password as much as possible and improving the security.
As can be seen from the above, the authentication method provided in this embodiment is applied to an electronic device, and is implemented by using a structured light module to obtain a continuous frame structured light image of a head of a user, and determining whether the user is a living body according to the continuous frame structured light image, if so, obtaining a digital password input by the user and biometric information of the user, where the biometric information includes at least one of a fingerprint feature, a voiceprint feature, a face feature, and an iris feature, then generating a code to be authenticated according to the digital password and the biometric information, and authenticating the user according to the code to be authenticated, so that static authentication and dynamic authentication can be combined, and biometric authentication and digital authentication are combined, thereby implementing authentication of the user from multiple dimensions, and the method is simple and high in security.
In this embodiment, the description will be made from the perspective of the authentication apparatus, and in particular, the detailed description will be made by taking an example in which the authentication apparatus is integrated in an electronic device.
Referring to fig. 2, an identity authentication method may specifically include the following processes:
201. the electronic equipment projects the structured light outwards through the structured light projector, prompts the head of a user to rotate, and then obtains a structured light image projected by the head of the user in a preset time through the camera to obtain a continuous frame structured light image.
For example, referring to fig. 3, when the electronic device is turned on or unlocked, an interactive interface may be generated, and an action prompt box may be displayed on the interactive interface to prompt the user to rotate the head, such as pan the head, and then, within a preset time period, such as 10s, the camera of the electronic device may obtain the structured light image projected on the head in real time, and simultaneously display the structured light image in the preview box, so that the user may see the structured light image.
202. The electronic equipment generates corresponding three-dimensional coordinates of the head according to each frame of structured light image, and calculates the rotation angle according to the corresponding three-dimensional coordinates of any two frames of structured light images.
For example, referring to fig. 4 and fig. 5, if the head of the user rotates from the position facing the electronic device to the position facing the electronic device, that is, from the position S1 to the position S4, if three-dimensional coordinates of two positions, i.e., the center point O and the nose tip N of the head, are selected to perform rotation angle calculation, and the coordinates of the two positions at the position S (i) are O (i) and N (i), i ∈ [1, 4], respectively, for any two frames of structured light images, such as the structured light images captured at the positions S1 and S2, the rotation angle α may be rrin1O 1N2 or rrin1O 2N 2.
203. The electronic device detects whether the rotation angle includes a preset angle, if so, the user is determined to be a living body, and the following step 204 is executed, and if not, the user is prompted to rotate again.
204. The electronic equipment acquires the digital password input by the user and the biological characteristic information of the user, wherein the biological characteristic information comprises at least one of fingerprint characteristics, voiceprint characteristics, face characteristics and iris characteristics.
For example, the preset angles may be 30 °, 40 ° and 60 °, and when the calculated rotation angle α includes the three angles, the user may be considered as a living body, thereby performing dynamic authentication, and at this time, the user may be prompted to input a digital password, and a fingerprint feature of the user may be acquired by a fingerprint detector, and/or a voiceprint feature of the user may be acquired by a microphone, and/or a face feature or an iris feature of the user may be acquired by a camera, etc., for static authentication.
205. The electronic equipment acquires the character string corresponding to the biological characteristic information, and performs combined conversion on the character string and the digital password to obtain a converted character string.
For example, if the biometric information is a voiceprint feature, in this case, the voiceprint feature can be processed by using the MD5 algorithm to obtain a corresponding MD5 value (i.e., a character string), which is assumed to be adddbds 7852, and in this case, if the input numeric password is 1234, the converted character string may be 1a2d3f4d bds7852 after the processing is performed in a cross-combination manner.
206. The electronic device generates a corresponding two-dimensional code according to the converted character string, and the two-dimensional code is used as a code to be verified, and matches the code to be verified with a preset verification code, if the matching is successful, it is determined that the user identity verification is passed, and if the matching is failed, the following step 207 is executed.
207. The electronic device accumulates the failure times, determines a corresponding waiting time according to the failure times, and returns to execute the step 204 when the waiting time is reached.
For example, the accumulated failure times may be set to be proportional to the waiting time, that is, the more the accumulated failure times, the longer the waiting time for inputting the password and acquiring the biometric information next time, for example, after 1 failure, the waiting time may be 15s, after two failures, the waiting time may be 30s, and so on.
As can be seen from the above, the identity authentication method provided in this embodiment is applied to an electronic device, where the electronic device may project structured light to the outside through a structured light projector, and prompt a user to rotate the head, then obtain a structured light image projected by the user head within a preset time period through a camera, obtain continuous frame structured light images, then generate corresponding three-dimensional coordinates of the head according to each frame of structured light image, and calculate a rotation angle according to the corresponding three-dimensional coordinates of any two frame of structured light images, then detect whether the rotation angle includes a preset angle, if so, determine that the user is a living body, and obtain a digital password input by the user and biometric information of the user, where the biometric information includes at least one of a fingerprint feature, a voiceprint feature, a face feature, and an iris feature, then obtain a character string corresponding to the biometric information, and the character string and the digital password are combined and converted to obtain a converted character string, then, a corresponding two-dimensional code is generated according to the converted character string and is used as a code to be verified, the code to be verified is matched with a preset verification code, if the matching is successful, the user identity verification is determined to be passed, if the matching is failed, the failure times are accumulated, the corresponding waiting time is determined according to the failure times, and after the waiting time is reached, the operation of obtaining the digital password input by the user and the biological characteristic information of the user is returned to be executed, so that the static verification and the dynamic verification can be combined, the biological verification and the digital verification are combined, the identity verification of the user is realized from multiple dimensions, the method is simple, and the safety is high.
According to the method described in the foregoing embodiment, the embodiment will be further described from the perspective of an authentication apparatus, which may be specifically implemented as an independent entity, or may be implemented by being integrated in an electronic device, such as a terminal, where the terminal may include a mobile phone, a tablet computer, and the like.

In this embodiment, the biometric information may be processed by using an MD5(Message Digest MD5, fifth edition) Algorithm to obtain a corresponding MD5 value (i.e. a character string), and in general, the calculated MD5 value is fixed for data of any length. The combination method can be set artificially, such as integral combination, that is, a character string (or a numeric code) is directly inserted into the back of a numeric code (or a character string) to form a long character string, or cross combination, that is, each character in the character string (or the numeric code) and each character in the numeric code (or the character string) are combined into a long character string in a cross insertion manner, and the like.
(5) Authentication module 50
And the verification module 50 is configured to perform identity verification on the user according to the to-be-verified code.
For example, the verification module 50 may be specifically configured to:
matching the code to be verified with a preset verification code;
if the matching is successful, determining that the user identity authentication is passed;
if the matching fails, accumulating the failure times, and determining the corresponding waiting time according to the failure times;
and returning to execute the operation of acquiring the digital password input by the user and the biological characteristic information of the user after the waiting time length is reached.
In this embodiment, the more the accumulated failure times, the higher the possibility that the user is an illegal user, so the accumulated failure times may be set in proportion to the waiting time, that is, the more the accumulated failure times, the longer the waiting time for inputting the password and acquiring the biometric information next time, thereby prolonging the time for the illegal user to break the password as much as possible and improving the security.
