Description

Method and system for batch signing of background files
Technical Field
The invention relates to the field of background file batch signature, in particular to a method and a device for background file batch signature.
Background
In the survey design, construction and construction industries, auditorium and graphic centers often sign a large number of PDF or OFD files. For batch format files, the page sizes of the files may be different and the rotation degrees may be different, but the stamping positions of the files are fixed. If the user is required to open the file each time, manually selecting a location to add an electronic signature to the file would consume a significant amount of time and effort. The files in large quantities are not suitable for being stored and signed at a client in an application scene, but signature operation is completed through a hardware medium, namely an intelligent password key USBKey, so that the files are required to be stored at a server, and a scheme for realizing online batch signature in a service system is realized through accessing a USBKey driving interface by the client.
With the popularization of informatization and continuous innovation of technology, the browser gradually gives up NPAPIs and ActiveX, and the integration of a business system does not use a browser fixedly any more, but an integration scheme supported by multiple browsers is needed. At present, the driving of the intelligent password key only provides a C or C++ language interface, and the background server is mostly realized by Java language and can not be directly called to the USBKey driving interface. The method calls the local service to realize the USBKey signature in a front-end js mode, so that the method becomes a better feasible scheme.
