Abstract
An electronic device that provides long-lived, but selectively ephemeral access to content is described. In particular, the electronic devices may provide secure content, which was generated based on protection information and the content, to a computer system. After receiving a share command, the electronic device may communicate, to the computer system, a unique token that is associated with a recipient in a communication network and an instruction to enable a recipient electronic device associated with the recipient to view the content. This unique token may allow the computer system to access the content in the secure content, so that the computer system has an ability to provide the content to the recipient electronic device. Moreover, after receiving an un-share command, the electronic device may temporarily or permanently disable the unique token on the computer system, so that the computer system is unable to access the content in the secure content.
