The output end of the communication module is electrically connected with the input terminal of the communication antenna 15.
The communication module, it is whole for the motion information to be sent to external identification according to communication control instruction
End carries out user identity authentication so that the identification terminal is based on the motion information.
In embodiments of the present invention, communication module can refer to bluetooth module etc..
Circuit structure diagram as shown in Figure 2, the PCB mould group 12 control the motion sensor mould group 13 receiving
When stating the pen point pressure of the transmission of pen point pressure sensor 11, start the motion information for acquiring signature pen, and the institute that will be received
It states motion information and is sent to external identification terminal by the communication antenna 15, so that the identification terminal is based on the movement
Information carries out user identity authentication.
Based on the above motion perception sensor, as shown in figure 3, the identity identifying method may comprise steps of:
Step S101, identification terminal receive the motion information that the motion perception signature pen is sent, and the motion information is
What the motion sensor mould group was acquired when user is signed using the motion perception signature pen；
Step S102, identification terminal extract motion characteristic value in the motion information；Illustratively, the motion feature
Value includes: speed, acceleration and three-dimensional space motion track.
Step S103, identification terminal judge whether the motion characteristic value is greater than preset maximum certification threshold value, it is described most
Big certification threshold value is that the motion information that records when being signed according to the user's history using the motion perception signature pen is true
Fixed, illustratively, maximum certification threshold value is the greatest measure in the motion information of record.
If the motion characteristic value includes: speed, acceleration and three-dimensional space motion track；Then step S103 can wrap
It includes: if the speed is greater than maximum speed certification threshold value, the acceleration is greater than maximum acceleration certification threshold value and the three-dimensional space
Between similarity between motion profile and historical record track be greater than default maximum similarity threshold value, determine the motion characteristic value
Greater than preset maximum certification threshold value.
If the motion characteristic value is greater than preset maximum certification threshold value, step S104, identification terminal determines user identity
Certification passes through.
The embodiment of the present invention passes through receives the motion information that the motion perception signature pen is sent first, the motion information
The motion sensor mould group is acquired when user is signed using the motion perception signature pen；Then in the fortune
Motion characteristic value is extracted in dynamic information；Judge whether the motion characteristic value is greater than preset maximum certification threshold value again, it is described most
Big certification threshold value is that the motion information that records when being signed according to the user's history using the motion perception signature pen is true
Fixed；If the last motion characteristic value is greater than preset maximum certification threshold value, it can determine that user identity authentication passes through.
The embodiment of the present invention can be based on the motion information of user's signature pen when signing, by will be in motion information
Motion characteristic value and maximum certification threshold value comparison, when motion characteristic value is greater than maximum certification threshold value, confirmation user authentication is logical
It crosses, the embodiment of the present invention makes to be no longer limited to by way of signature authentication user identity only by identifying user handwriting, but can
With the motion information based on signature pen, since name is different and writing style is different, different user passes through movement in signature
The collected motion information of sensor module is also different, motion information is obtained when signing as the basis of user identity authentication, can
To reduce the probability that signature is forged, the accuracy rate of user's signature identification is improved.
Based on previous embodiment, in another embodiment of the present invention, as shown in figure 4, the method also includes:
If the motion characteristic value is less than preset maximum certification threshold value, step S201 judges that the motion characteristic value is
No to be less than preset minimum certification threshold value, the minimum certification threshold value is to use the motion perception label according to the user's history
What the motion information that word pen records when being signed determined, the minimum certification threshold value is less than the maximum and authenticates threshold value；
In this step, illustratively, if the speed is less than minimum speed certification threshold value, the acceleration is less than minimum
Acceleration certification threshold value and the similarity between the three-dimensional space motion track and historical record track are less than default minimum similar
Threshold value is spent, determines that the motion characteristic value is less than preset minimum certification threshold value.
If the speed is greater than minimum speed certification threshold value, the acceleration is greater than minimum acceleration and authenticates threshold value and described three
Similarity between dimension space motion profile and historical record track is greater than default minimum similarity degree threshold value, determines that the movement is special
Value indicative is greater than preset minimum certification threshold value.
If the motion characteristic value is less than preset minimum certification threshold value, step S202 determines that user identity authentication fails.
If the motion characteristic value is greater than preset minimum certification threshold value, step S203 prompts user to re-start signature.
In another embodiment of the present invention, a kind of identification authentication system is also provided, is applied to identification terminal, the identification
Terminal and motion perception signature pen communicate to connect, and motion sensor mould group are provided in the motion perception signature pen, such as Fig. 5 institute
