Problems solved by technology

PDF signature: supports the three mainstream platforms of Andriond, iOS and WinPhone7, and can directly sign and verify in the mobile device. The digital certificate and seal stamp are encrypted and stored on the mobile device. However, the calculation amount of the mobile terminal under this method The amount of interaction with and interaction is large, and the processing efficiency is low

Embodiment Construction

[0030] The method of the present invention mainly includes two parts: two-dimensional code generation at the PC end and code scanning and signing at the mobile end. Sign the picture on the page, then sign it on the mobile terminal, and finally synthesize the format file of the seal on the server side after signing the seal. Its specific content is as follows:

[0031] 1. Generate QR code on PC

[0032] On the PC side, the server-side file identifier FID and the corresponding page number and zoom ratio are passed in, and the corresponding image information can be generated through background processing and presented on the front end. When browsing a certain page for signing, at this time, structure QR code information such as XML or JSON can be generated according to the FID and PageNum data. Among them, FID: file identifier, used to mark the current document to be signed; PageNum: current page.

[0033] 2. Scan the code and sign on the mobile terminal

[0034] Using the cor...

Abstract

The invention discloses an electronic signature method, which mainly comprises two large parts including a PC end two-dimensional code generation part and a mobile terminal code-screening signature part. The method comprises the following steps: transforming a page to be signed to two-dimensional code information by a PC end, obtaining a picture of the page to be signed from a service end after a mobile terminal screens the two-dimensional code information, signing on the mobile terminal, and synthesizing a layout file of the signature on the service end finally after signing. According to the method and system of the invention, the mobile terminal does not need to load the complete signature file, and only loads the information of the current signature page, so as to reduce the interaction with the service end and flow consumption; other operation except digital signature operation are performed on the service end, the safety of the operation can be ensured and the treatment efficiency is also improved.

Description

technical field [0001] The invention relates to an electronic signature method and system. Background technique [0002] The current mobile terminal signature requires loading the file to be signed on the mobile terminal, and using soft certificates, SD cards, Bluetooth UKEYs, etc. to perform signature and seal calculations. Its disadvantages are: in the process of signing and signing, all the data to be signed need to be downloaded to the mobile terminal, which increases the interaction traffic on the one hand, and greatly increases the calculation amount of the mobile device on the other hand. [0003] Commonly used electronic signature requirements are generally applied in Office documents, PDF documents and WEB approval. Since MS Office does not currently support Andriond and iOS versions, it is difficult for other Office versions to maintain the layout for browsing complex Office documents. Therefore, at present, it is difficult to directly support the signing of Offi...
