Research Based On Windows Sharepoint Workflow

In recent years,the WorkFlow of research and technology applications have attracted the reserchers, developers and users of common concern. Such as computer supported cooperative work, paperless office, form transfer, collaboration systems and office automation of these concepts are already proposed, but because the field of technology and applications to achieve the restrictions repeatedly ran aground. With the popularity of high-performance computer and distributed networks and business process reengineering and technological development, all this will likely become a reality, in order to achieve all this, we need to establish a task related to the effective implementation of the centralized management of heterogeneous distribution - The implementation of the environment, work flow management system to breed from this lives.Based on the workflow of the technology of the prototype system, in this prototype system on the basis of a workflow management system. This management system using Microsoft Windows SharePoint Server collaboration platform Window WorkFlow Foundion workflow engine to achieve the design workflow. The programme Make that users can easily use Infopath 2007 to form the design template, And to facilitate its deployment in WSS, and to form a digital signature to verify signatures and encryption, decryption. So that users can complete its workflow under the relaxed security environment.With office automation in the security of the documents, the authenticity of the requirements of the increase, particularly for handwritten signatures, more stringent requirements of the chop to the Word, Excel, Xml document signed, sealed, the need to achieve more One sign, verifiable signature, authentication, anti-denial, and other functions.This paper will combined digital signature and office automation system,in accordance with the W3C standards, to achieve the Xml file encryption and decryption and digital signature to ensure that the document data integrity, confidentiality of documents and digital signatures to support the non-repudiation.
