Abstract: A method receives authentication credentials for a user from a client device and receives a request from the user for content stored on a remote storage system. A portion of the content is encrypted and a corresponding decryption key is available only at the computer system. The remaining portion of the content is unencrypted. The method retrieves the content from the remote storage system and uses the received credentials to determine whether the user is authorized to view the encrypted portion. When the user is not authorized, the method forms alternative content by replacing the encrypted portion with a substitute element and transmits the alternative content to the client device. When the user is authorized, the method decrypts the encrypted portion of the content using the decryption key, and combines the decrypted portion with the unencrypted portion to form updated content. The updated content is transmitted to the client device.

Abstract: A method is performed at a computer system having one or more processors and memory storing one or more programs executed by the one or more processors. The method includes receiving a first data transmission from a first client system, where the first data transmission including a first document, the first document having one or more portions that are marked as private; encrypting the marked portions of the first document using a key; and sending a second data transmission to a destination system, where the second data transmission includes a second document, the second document including the encrypted marked portions of the first document and a remainder of the first document that is not marked as private. The key is unavailable to the destination system. The second document is stored at the destination system.

Abstract: A method is performed at a computer system having one or more processors and memory storing one or more programs executed by the one or more processors. The method includes generating a document, including marking one or more portions of the document as private; and sending the document to an intermediary system for transmission to a destination system. Prior to the document being transmitted to the destination system, the marked portions of the document are encrypted by the intermediary system using a key that is unavailable to the destination system.

Abstract: A computer-implemented method of sharing data between computer applications is discussed. The method includes receiving, at an application server sub-system of a hosted computer server system and from a first computing device that is remote from the hosted computer server system, commands interacting with an electronic document served by the application server sub-system, and receiving at the hosted computer server system a command to copy content from the electronic document to an electronic clipboard. The method also includes storing, at a clipboard server sub-system of the hosted computer server system, that is separate from the application server sub-system, data that represents the content, receiving a request for the stored data that represents the content, and delivering, from the clipboard server sub-system to a second computing device, the data that represents the content.
