Abstract
Techniques disclosed herein decouple a document's structure from its general content wherein the structure is retained in plaintext (both at a client device and in a server system) and the data is retained in cyphertext, and where the cloud-based server system is not tasked with the saving or management of the relevant cryptographic keys. Because the network- or cloud-based server system has 'zero-knowledge' about the document's data content or the relevant cryptographic keys, an attack on the server system does not put the security of the document's data at risk. In addition, the network- or cloud-based server system may be used to perform the computationally intensive tasks of converting the document between a first format (often associated with a full-function document processing application not supported by the client device) and a second format (easily displayed and manipulated by a client device).
