Patent ID: 10587585

Abstract:
Users desire a system that provides for the setting of custom, content-agnostic, permissions at a message, document, and/or sub-document-level through a communications network. Such a system may also allow the user to apply customized privacy settings and encryption keys differently to particular parts of a document. Customized encryption keys may be applied to particular parties (or groups of parties) to enhance the security of the permissions settings. In the case of structured document file types, dynamically-rendered content can present a challenge to accurately display to viewers, because one or more of the document's values referred to by the dynamically-rendered content may be encrypted or otherwise unavailable to the recipient—even though the dynamically-rendered content itself is viewable by the recipient. Systems are presented herein to handle the presentation of dynamically-rendered content in structured documents, while preserving the sender's intent to not disclose certain underlying or related information in the document.
