Description

Digital signature system and method

The invention relates to a digital signature system and method, in particular to a digital signature system and method capable of transmitting handwritten information.

Electronic Data Interchange (EDI) is an electronic means of transferring job documents such as orders and invoices. It is a structured transactional data exchange from calculator to calculator. Because EDI can reduce or even eliminate paper documents in the trade process, EDI is popularly known as “paperless trade”. EDI includes three aspects, namely, calculator terminal applications, communication networks, and data standardization.

In the application of the calculator terminal, the existing EDI system terminal mostly uses a computer or other small input device with a single function. However, the computer terminal has poor portability, and the small input device has a single function, and the two generally do not have the handwriting annotation function, which leads to limitations in use in some fields, for example, a doctor prescribes a handwritten handwriting as a responsibility certificate.

In view of this, it is necessary to provide a digital signature system and method that can record and transmit handwritten information.

A digital signature system, including an EDI server, a user terminal connected to an EDI server via a wireless network, a management server and a database connected to an EDI server via a network, and an EDI server from the management server according to a user instruction Obtaining the required document, and displaying the document in the user terminal, the user terminal includes a handwriting input module and a wireless transceiver module, and further includes: a mode selection module, and selecting a handwriting mode or an electronic file mode according to a user instruction; Generating a module, recording track information generated by the handwriting input module, converting the track information into a document of a corresponding format according to a current mode selected by the mode selection module, and transmitting the file to the EDI server through the wireless transceiver module; the EDI server The document synthesizing module is configured to synthesize the document generated by the document generating module and the document obtained from the management server into a new document, and store the new document in the database.

The digital signature method implemented by the digital signature system comprises: selecting a handwriting mode or an electronic file mode according to a user instruction; acquiring a required document from a management server according to a user instruction, and transmitting the required document to the user terminal; the user terminal receiving The user's handwriting input information, and generate corresponding trajectory information; convert the recorded trajectory information into a corresponding format document according to the selected current mode; transfer the generated document to the EDI server; the EDI server will receive the document and The documents obtained from the management server are synthesized into a new document; the synthesized document is stored in the database.

Compared with the prior art, the user terminal of the present invention generates a document in a corresponding format according to an instruction of the user, and synthesizes and saves the generated document and the required document provided by the management server in the EDI server, thereby enhancing the portability of the user terminal. Sexuality, and the system has handwritten annotation function, which expands the limitations of the existing EDI system application, omitting the process of paper signing and scanning in the business office process.
