Systems and methods for secure cloud-based media file sharing

摘要

Cloud-based systems and methods to securely share electronic files use a cloud or virtualized server to handle management tasks related to file sharing, while file storage is maintained securely by servers that are not part of the cloud. The content of the file to be shared is not transmitted to or by the cloud. Share requests from file senders, notifications to target recipients, and retrieve requests from target recipients are transmitted to and/or by the cloud.

主权项

1. A cloud-based method of securely sharing electronic files using a plurality of server platforms cooperating to implement a virtualized server, the method comprising:
receiving a share request at the virtualized server from a user, wherein the share request indicates intent by the user to share an electronic file with a target file recipient, wherein the electronic file is stored and accessed independently from the virtualized server through a storage server, wherein the storage server uses one or more types of access control, and wherein the virtualized server uses one or more types of access control that are independent from the one or more types of access control used by the storage server; providing a notification to the target file recipient, wherein the notification indicates intent to share the electronic file with the target file recipient; receiving a retrieve request at the virtualized server from the target file recipient, wherein the retrieve request indicates intent by the target file recipient to receive a copy of the electronic file; and transmitting one or more instructions from the virtualized server to the storage server that cause retrieval of the copy of the electronic file from the electronic storage such that the copy of the electronic file is neither stored on the virtualized server nor transmitted through the virtualized server.
