Systems and methods for securely providing information external to documents

摘要

A computer-implemented method for securely providing information external to documents may include identifying a document that may include at least one link to content external to the document, retrieving the content external to the document from the link, converting the content external to the document to embeddable content in a secure format that can be embedded within the document and creating a secure version of the document at least in part by embedding the embeddable content that has been converted to the secure format into the document. Various other methods, systems, and computer-readable media are also disclosed.

1. A computer-implemented method for securely providing information external to documents, at least a portion of the method being performed by a computing device comprising at least one processor, the method comprising:
identifying a document that comprises a file comprising at least one link to content external to the document, wherein the document is destined for a restricted network environment that only allows secure content; retrieving, prior to delivering the document to the restricted network environment, the content external to the document from the link; converting, prior to delivering the document to the restricted network environment, the content external to the document to embeddable content in a secure format that can be embedded within the document by storing the embeddable content within the file by rendering the content for display and creating an image of the rendered content; creating, prior to delivering the document to the restricted network environment, a secure version of the document at least in part by embedding the embeddable content that has been converted to the secure format into the document by storing the embeddable content within the file, thereby providing secure access to the content external to the document via the file rather than via a reference to data stored outside the file; delivering the secure version of the document to the restricted network environment.
