Digital file encapsulation method based on digital file system

Abstract

The invention discloses a digital file encapsulation method based on a digital file system, and relates to the field of electronic file encapsulation. The digital file encapsulation method based on the digital file system comprises the steps of: (1), obtaining document data, a template file and a signature certificate from an electronic file management system; (2), generating an encapsulation packet according to the document data, the template file and the signature certificate; and (3), storing the content of the encapsulation packet as a file in the eep format, wherein the step (2) comprisesthe steps of: 1, generating a signed object in the template file according to document metadata and a document attachment; 2, generating an electronic signature block in the template file according to the document metadata and the signature certificate; 3, generating a locked signature in the template file according to the document metadata and the signature certificate; and 4, combining the signed object, the electronic signature block with the locked signature in the template file, so that the encapsulation packet is obtained. According to the digital file encapsulation method based on thedigital file system disclosed by the invention, electronic file encapsulation formats and requirements are stipulated; the electronic file encapsulation packet format generated according to the methodhas nothing to do with computer software and hardware; and thus, document exchange, long-term storage and utilization are conveniently carried out.

Description

technical field [0001] The invention relates to the field of electronic file packaging, in particular to a digital file packaging method based on a digital file system.
