Abstract (en)
[origin: WO2016109588A1] A method involves providing tiered access control to a document. The method may include determining document portions of the document, determining encryption levels and encryption keys for each of the document portions, determining an encryption order for each of the document portions, the encryption levels, and the encryption keys, encrypting each of the document portions using the encryption levels, encryption keys, and encryption orders for each of the document portions, and transmitting the document to client interfaces. The method may further include receiving the document at a client device, determining the document portions of the document, decrypting one or more of the document portions using client encryption keys present at the client device into decrypted sections, and displaying the decrypted sections on a client interface of the client device.
