Hereinafter, each step in the above-described electronic signature method in the present exemplary embodiment will be explained and explained in detail with reference to the drawings.
In step S110, when an electronic signature trigger signal of an electronic document to be signed by a user is received, an electronic signature process of the user at a predetermined signature position is monitored in real time to obtain handwriting dynamic feature data of the user.
In the embodiment of the present example, referring to fig. 2, when receiving an electronic signature trigger signal of an electronic document to be signed sent by a user terminal 202, a server 201 automatically monitors an electronic signature process of a user at a predetermined signature position on a screen of the user terminal 202 in real time, and can accurately obtain handwriting dynamic characteristic data, such as pen movement tendency, in the user signature process by using methods such as screenshot, so as to effectively ensure verifiability of a user signature and improve accuracy of user signature verification. The server 201 may be any terminal having a function of executing a program instruction and a data storage function, such as a server, a cloud server, a computer, and the like, and the user terminal 202 may be any terminal provided with a display screen, such as a mobile phone, a counter machine, and the like, which is not limited herein.
The electronic document to be signed is an electronic version document which requires the user to carry out electronic signature to confirm the transaction content of the document. An electronic signature is simply a signature of the user's name on the display screen, for example, by means of an electronic signature pen. The predetermined signature position is a position provided on the display screen for a user to sign with an electronic signature pen, and may be a position including the entire display screen or a part of the display screen, which is not particularly limited herein.
When the user finishes filling and confirms the document content, the electronic signature trigger signal for signing the electronic document to be signed can be triggered by clicking a signature button and the like. When the monitoring server receives an electronic signature trigger signal of an electronic document to be signed by a user, the electronic signature process of the user at a preset signature position is monitored in real time, data of a process that the user can reflect changes of handwriting, force of a pen and the like in the electronic signature process of the user can be accurately obtained, and further dynamic feature data of the handwriting of the user, such as the change data of the order of the pen and the force in the signature process of the user, can be accurately obtained. The handwriting dynamic characteristic data of the user can be used for accurately verifying the signature of the user when an event needing to verify the authenticity of the signature of the user occurs later. The verifiability and the verification accuracy of the electronic signature on the document are effectively ensured.
In an implementation manner of this example, referring to fig. 3, when an electronic signature trigger signal of an electronic document to be signed by a user is received, monitoring an electronic signature process of the user at a predetermined signature position in real time to obtain handwriting dynamic feature data of the user, including:
step S310, when an electronic signature trigger signal of an electronic document to be signed by a user is received, monitoring the electronic signature process of the user at a preset signature position in real time, and acquiring a sub-electronic signature image from the preset signature position according to a preset time interval;
and S320, serially connecting each sub-electronic signature image according to the sequence of the time points corresponding to each sub-electronic signature image to obtain the electronic signature process animation of the user as the handwriting dynamic characteristic data of the user.
The sub-electronic signature image is acquired from a predetermined signature position at predetermined time intervals, for example, automatically screen-shot from an electronic signature display screen through a screen every 0.05 second, and then the entire screen image is acquired or a partial image of the predetermined position is cut out as the sub-electronic signature image. The sub electronic signature image is an electronic signature image at each time point. Then, each sub-electronic signature image is connected in series according to the sequence of the corresponding time points of each sub-electronic signature image, namely, each sub-electronic signature image is used as a video image frame, then, each frame of image is connected in series to obtain the user electronic signature process animation, the electronic signature process animation is used as the handwriting dynamic characteristic data of the user, the signature order characteristic of the user signature process can be accurately analyzed, the order characteristic is caused by the long habit of one person, the method can be used for accurately verifying the authenticity of the signature of the user later, and the verifiability of the validity of the electronic signature of the user document is effectively ensured.
In an implementation manner of this example, when an electronic signature trigger signal of an electronic document to be signed by a user is received, monitoring an electronic signature process of the user at a predetermined signature position in real time to obtain handwriting dynamic feature data of the user, including:
when an electronic signature trigger signal of an electronic document to be signed by a user is received, monitoring the electronic signature process of the user at a preset signature position in real time, and acquiring force data of each time point of the electronic signature process of the user at the preset signature position according to a preset time interval;
and forming the handwriting dynamic characteristic data of the user according to the strength data of each time point in the electronic signature process of the user and a preset rule.
By monitoring the electronic signature process of a user on a touch screen, the force data of each time point of the electronic signature process of the user at a preset signature position can be accurately acquired through a pressure sensor and the like according to a preset time interval, namely the pressure data of a pen point and other signature ends of an electronic signature pen on the touch screen in the signature process of the user. And then, the strength data of each time point in the user electronic signature process is combined into the handwriting dynamic characteristic data of the user according to a preset rule, so that the habitual strength change data in the user signature process can be accurately expressed, the method can be further used for accurately verifying the authenticity of the signature of the user later, and the validity and verifiability of the electronic signature of the user bill can be effectively ensured.
In an implementation manner of this example, the step of composing the handwriting dynamic feature data of the user according to a predetermined rule from the strength data of each time point of the user electronic signature process includes:
establishing a handwriting dynamic characteristic rectangular coordinate system with the force data as a longitudinal axis and the time as a transverse axis;
taking the value of the force data of each time point in the user electronic signature process as a longitudinal coordinate value, and taking the time point corresponding to each force data as an abscissa value to obtain each point in the handwriting dynamic characteristic rectangular coordinate system;
and connecting all points in the handwriting dynamic characteristic rectangular coordinate system to obtain an electronic signature strength change curve of the user as handwriting dynamic characteristic data of the user.
By establishing a handwriting dynamic characteristic rectangular coordinate system which takes the force data as a vertical axis and time as a horizontal axis. Then, the value of the force data at each time point in the user electronic signature process is taken as a longitudinal coordinate value, and the time point corresponding to each force data is taken as an abscissa value, for example, when the user is at 0.2 second, the acquired force data is 0.25N, and then the coordinates (0.2, 0.25) of each point in the handwriting dynamic characteristic rectangular coordinate system can be obtained, wherein the abscissa value is 0.2 second, and the ordinate value is 0, 25N. Therefore, the force data in the electronic signature process of the user can be accurately and directly expressed by a coordinate system. And then, connecting all points in the handwriting dynamic characteristic rectangular coordinate system to obtain an electronic signature strength change curve of the user, wherein the electronic signature strength change curve is used as handwriting dynamic characteristic data of the user. Therefore, the change condition of the habit of exerting force during habitual signature of the user can be accurately obtained, and the change condition can be further used for accurately verifying the authenticity of the signature of the user in the future, so that the validity and verifiability of the electronic signature of the document of the user can be effectively ensured.
In an implementation manner of this example, the step of composing the handwriting dynamic feature data of the user according to a predetermined rule from the strength data of each time point of the user electronic signature process includes:
setting corresponding color values for the strength data of each time point in the user electronic signature process according to the strength data value of each time point;
acquiring position points in the preset signature positions corresponding to the strength data of each time point in the user electronic signature process;
and acquiring the cloud picture of the electronic signature force data of the user according to the color value and the position point, and using the cloud picture as the handwriting dynamic characteristic data of the user.
For the strength data of each time point in the user electronic signature process, a corresponding color value is set according to the magnitude of the value of the strength data of each time point, that is, for example, when the user is in 0.2 second, the collected strength data is 0.25N, when the user is in 0.3 second, the collected strength data is 0.22N, when the strength data is 0.25N, the color value is set to rgb (120, 0, 0) for the strength data of the user in 0.2 second, and when the strength data is 0.25N, the color value is set to rgb (130, 0, 0) for the strength data of the user in 0.3 second. Therefore, the force data of each time point of the user can be accurately and vividly represented by the color value.
By establishing a positioning coordinate system at a preset signature position in advance and then accurately receiving the position of a signature end such as a pen point in the user signature process, the position point in the preset signature position corresponding to the strength data of each time point in the user electronic signature process can be accurately obtained.
And finally, acquiring the cloud picture of the electronic signature strength data of the user according to the color values and the position points, namely displaying the colors corresponding to the color values of all the time points on the position points in the preset signature positions corresponding to all the time points to obtain the signature with color change of the user, namely the cloud picture of the electronic signature strength data. Therefore, the strength of each position of the user signature can be clearly and visually displayed, and the method can be further used for accurately analyzing the authenticity of the user signature later, and effectively ensures the validity and verifiability of the electronic signature of the user document.
In step S120, when an electronic signature submission instruction of the user to the electronic document to be signed is received, an electronic signature image of the predetermined signature position is acquired.
In the embodiment of the example, after the user completes the electronic signature, when the user triggers the electronic signature image confirmation or the electronic signature image submission command by clicking a confirmation submission button or other operations, the user may receive an electronic signature submission instruction for the electronic document to be signed. At this time, the electronic signature image at the predetermined signature position can be accurately acquired by screen capture or the like. Therefore, when the authenticity of the user signature needs to be verified later, the static characteristics of the user electronic signature, such as distribution and architecture among strokes of the signature, can be accurately analyzed according to the electronic signature image, and the user signature can be accurately verified.
In step S130, the document number of the electronic document to be signed and the document number of the user are obtained.
In the embodiment of the example, by acquiring the document number of the electronic document to be signed of the user and the certificate number of the user, the unique document number can be used for accurately associating the current electronic document signed by the user, and the unique certificate number of the user can also accurately associate the identity of the current user. Furthermore, the electronic document signing method can be used for storing the electronic document signing image and the like of the user in a correlation mode in the subsequent steps, and the reliable correlation between the user signature and the electronic document to be signed is guaranteed.
In step S140, the handwriting dynamic feature data, the electronic signature image, the document number, and the certificate number are stored in a predetermined location in an associated manner, and an electronic signature number is generated.
In the embodiment of the example, the data which can accurately reflect the authenticity of the signature of the user, such as the handwriting dynamic characteristic data, the electronic signature image, the document number, the certificate number and the like of the current user, are stored in the preset position, and the reliability of obtaining the verifiable data when the signature of the user and the authenticity of the identity are required to be verified can be effectively ensured, wherein the preset position is a preset storage server and the like. Meanwhile, the unique electronic signature number associated with the preset position is generated after the electronic signature number is stored to the preset position, and the electronic signature related data of the user stored in the moving position can be accurately acquired according to the electronic signature number.
In one embodiment of the present example, the associating and storing the handwriting dynamic feature data, the electronic signature image, the document number, and the certificate number at a predetermined position and generating an electronic signature number includes:
