Abstract
Methods, systems, and computer-readable storage media for secure document sharing. The method includes receiving, from a server system, metadata associated with a document stored by the server system. The document includes protected data. A user input including a request to access the document stored by the server system is received. The user input is processed to validate the request. A display of the document in a read only mode is generated. A user attempt to duplicate of at least one portion of the document presented for display is detected. A duplication identifier is added to the at least one portion of the document. The duplication identifier is indicative of a duplication source of the document presented for display.
