Secure Key Management for Roaming Protected Content

Abstract

Content on the device is encrypted and protected based on a data protection key corresponding to the specific identity of the user of the device. The protected content can then be stored to the cloud storage, and the protected content can be transferred from the cloud storage to various other ones of the user's devices. The data protection keys used to retrieve plaintext content from protected content are maintained by the user's device. The data protection key may be securely communicated to other ones of the user's devices to allow any of the user's devices to access the protected content.

Description

Background technique [0001] As computing technology has advanced, many different types of computing devices have become common. Users often have a variety of different computing devices, such as laptop or desktop computers, tablet devices, smartphones, and so on. Networking services or cloud services can be used to allow users to share data across these multiple devices, giving users access to data from any of their multiple devices. However, providing data to such services can be annoying to the user, as it can result in his or her data that the user would otherwise keep private, becoming available to the service provider or other entity (e.g., hacking). or malicious users who otherwise compromise the service) are available. Contents of the invention [0002] This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential fea...
