Description

An integrated method of electronic signature system based on virtual printing

technical field

The invention relates to a control method of an electronic signature system based on virtual printing technology.

Background technique

Electronic signature is a general term for modern authentication technology. The United Nations "Model Law on Electronic Commerce" stipulates that an electronic signature is data in electronic form that is included in, attached to, or logically associated with a certain data message. It can It is used to verify the identity of the signatory associated with the data message and to indicate that the signatory approves the information contained in the data message. The "Electronic Signature Law of the People's Republic of China" was passed by the Eleventh Session of the Standing Committee of the Tenth National People's Congress of the People's Republic of China on August 28, 2004, and came into effect on April 1, 2005. The law is considered China's first legislation in the sense of a true e-commerce law. The "Electronic Signature Law" is an important step for my country to promote the development of e-commerce and remove obstacles to the development of e-commerce.

Electronic signature technology is still an emerging technology and lacks a mature application environment. Existing electronic signature systems often need to work with existing operating systems, OA systems, etc., and the information interaction and response technologies between them are not yet perfect. More complex procedures are required to realize the connection between the existing work system and the electronic signature system.

Any discussion of the background technology throughout the specification does not mean that the background technology must be the prior art known to those skilled in the art; any discussion of the prior art in the entire specification does not mean that the prior art must be widely known Commonly known or must constitute common general knowledge in the field.

Contents of the invention

The present invention intends to provide an electronic signature system integration method based on virtual printing, so as to realize the simple and flexible connection between the existing work system and the electronic signature system.

A virtual printing-based electronic signature system integration method in this solution includes the following steps:

The electronic signature system continuously listens to the printing signal of the working system;

When the electronic signature system detects the printing signal of the working system, the electronic signature system obtains the printing document output by the working system, and starts the signature procedure of the electronic signature system. After the signing program is started, it is ready to receive the input of signing information.

This solution cleverly borrows the printing mechanism in the existing work system, because usually a pre-preparation of the signature program is printing. Once the electronic signature system detects the print signal of the work system, it means that a user needs to start the signature program. At this time, the system is set to directly start the signature program without the need for the user to issue an order, and there is no need to set up other complicated control programs. It can easily and flexibly realize the connection between the electronic signature system and the existing working system. After the user's electronic signature is completed, the electronic signature data and Print files are packaged and stored.

Further, after the electronic signature system obtains the print file output by the working system, the print file information is analyzed on the electronic signature system and converted into an electronic file that can be electronically signed. The content printed by the user can be virtually printed on the output device of the electronic signature system, which can be various output means such as image and voice, so as to facilitate the user's next judgment operation.

Further, it includes a signature mark that can be set in the content of the printed file, and the signature mark is used to locate the display position of the electronic signature in the printed file. The signature mark can be an invisible mark or a specific character string, and this scheme is more convenient for the user to control the display position of the electronic signature in the printed document.

Detailed ways

The present invention will be described in further detail below by means of specific embodiments:

In this embodiment, a personal computer is included, which is connected to the electronic signature terminal through a USB cable.

The hardware of the electronic signature terminal includes a signing platform. A host computer is installed inside the signing platform. The host has built-in memory, time service module, GPS module, and 3G module. The host computer is connected to the Internet for network interaction of information. The time service module receives the national time service center. The absolute time sent (that is, the national standard time), the 3G module is used for wireless data communication with the outside world. The listener and receiving program of printing signal is solidified in the controller.

A writing screen, a writing pen, a camera, and an iris recognition device are connected to the host through cables. The writing screen, writing pen, camera, and iris recognition device are all installed on the signing table according to a typical installation method. The iris recognition device is an optional device, which can collect the iris information of the signatory in a known and typical manner when needed.

The writing screen has a pressure sensitivity level of 512 or above. A fingerprint reader is installed where the thumb usually is on the writing pen. A sweat sensor is also installed on the writing pen. The host can collect the sweat composition of the signatory at any time as needed.

The online signature recording method is carried out according to the following steps, and the order of the steps can be adjusted as needed:

By default, the host collects various signature parameters at a sampling frequency of 5 milliseconds, that is, the interval between each sampling period is 5 milliseconds. The time interval of sampling frequency can be adjusted according to actual needs, such as changing to 1 millisecond, 10 milliseconds, 100 milliseconds, etc. The shorter the time interval of sampling frequency, the more detailed the recording, but at the same time, the increase of data volume will cause problems for the computer in computing and The greater the pressure on storage;

When the signatory needs to sign through this system, just hold the writing pen, and then press the fingerprint reader with the thumb, and the host will enter the working state after detecting the signatory’s fingerprint (need to inform the signatory in advance of the steps to collect fingerprints) , at this time the camera starts to collect the signatory's appearance and surrounding environment images;

In each sampling cycle, the host computer stores the following signature parameters: the scene data to be stored includes six-dimensional vectors X, Y, Z, T, A and F, where X, Y are the coordinate information of the signature, that is, the outline, and Z is Signature pressure sensitivity, T is the relative time and absolute time when signing, A is the auxiliary information, F is the sampling frequency of the signing terminal, which is encrypted while storing;

According to the absolute time of each step of the stroke and the displacement of the handwriting, the relative time between each stroke and the strokes is calculated, and the speed and acceleration change state during the writing process of each stroke are also calculated, and the above calculation results are encrypted and stored.

In the working state, the host computer continuously listens to the signal sent by the USB cable. When it detects the printing signal, it starts to receive and store the printing signal, and at the same time starts the writing screen to enter the standby state, and virtualizes the printing signal The print is displayed on the writing screen, and the user can immediately electronically sign the printed document on the writing screen, and then the host will pack and store the printed file and the electronic signature, and finally use the printer connected to the electronic signature terminal to print on paper.

In another embodiment, the difference from the above-mentioned embodiment is that if the host computer detects the signature mark of “[Electronic Signature Position]” in the printed document, the printed document will not be displayed on the writing screen, and the The signature of the input confirmation is positioned at the signature mark.
