Patent number: 10642962Abstract: For securing content accessed from storage device, the storage device is associated with a licensee identifier. The licensee identifier is provided as input to an algorithm that generates, based on the identifier, a determinate set of instructions for a computer, for example, source code in a coding language, compiled binary code, or pseudo code that is capable of being translated into source code. The code, once compiled to machine-usable form, can be executed by a processor to perform a permutation operation that is unique to the licensee identifier. The output of the permutation operation can be used for protecting data provided by the storage device.Type: GrantFiled: July 28, 2015Date of Patent: May 5, 2020Assignee: Western Digital Technologies, Inc.Inventors: Carlos Frederico Amaral Cid, Matthew Warren Dodd, David L. Blankenbeckler, Joseph Edward Halpern, III, Ian E. Harvey, Christopher R. Odgers

Patent number: 10181166Abstract: A user selection of one or more of a plurality of content is received. The selected content is encrypted by a first encryption key that is remote and unknown to the distribution server. Payment information associated with the user selection is also received and verified. The selected content from is retrieved from a remote database. The first encryption key corresponding to the selected content to decrypt the encrypted content corresponding to the user selection is obtained. Decryption is performed by a hardware-based engine of the distribution server that is isolated from a host processor of the distribution server. The content corresponding to the user selection is encrypted according to a second encryption key that is known to the distribution server.Type: GrantFiled: March 29, 2018Date of Patent: January 15, 2019Assignee: Adobe Systems IncorporatedInventors: David L.

Patent number: 9424400Abstract: The present invention relates to digital rights management (DRM) for content that may be downloaded and securely transferred from one storage to another storage. The storage may be a disk drive, or network attached storage. The storage performs cryptographic operations and provides a root of trust. The DRM system enables secure copying or transfer of content from one storage device to another storage device. In this embodiment, a trusted server that is authenticated and trusted by both storage devices brokers the transfer of content. The trusted server may be a separate entity of the DRM system or may be a component or function of an existing server of the DRM system. In another embodiment, the storage devices may transfer content in a peer-to-peer fashion. The transfer of content may be authorized and controlled based on a digital certificate associated with the content.Type: GrantFiled: December 15, 2014Date of Patent: August 23, 2016Assignee: Western Digital Technologies, Inc.Inventors: David L.

Patent number: 9342701Abstract: The present invention relates to digital rights management (DRM) for content that downloaded and saved to a storage device. The storage may be a disk drive, or network attached storage. In addition, the storage device performs cryptographic operations and provides a root of trust. The DRM employs a binding key, a content key, and an access key. The binding key binds the content to a specific storage and is based on a key that is concealed on the storage. The binding key is not stored on the storage device with the content. The content key is a key that has been assigned to the content. The access key is determined based on a cryptographic combination of the content key and the binding key. In one embodiment, the content is provisioned based on the access key and stored in encrypted form in the storage device.Type: GrantFiled: August 20, 2014Date of Patent: May 17, 2016Assignee: Western Digital Technologies, Inc.Inventors: David L.

Patent number: 9214184Abstract: The present invention relates to digital rights management (DRM) for content that may be downloaded and bound to a storage device. The storage device may be an intelligent storage device, such as a disk drive, or network attached storage. In addition, the storage device is capable of performing cryptographic operations and providing a root of trust. In one embodiment, the DRM employs a binding key, a content key, and an access key. The binding key binds the content to a specific storage and is based on a key that is concealed on the storage. However, the binding key is not stored on the storage with the content. The content key is a key that has been assigned to the content, for example, by a trusted third party. The access key is determined based on a cryptographic combination of the content key and the binding key. In one embodiment, the content is encrypted based on the access key and stored in encrypted form in the storage device.Type: GrantFiled: April 30, 2012Date of Patent: December 15, 2015Assignee: Western Digital Technologies, Inc.Inventors: David L.

Patent number: 8762708Abstract: In accordance with one aspect of the invention, a system is provided that includes a database configured to store data according to a first encryption protocol such as an FDE HDD protocol. The data provided to the database is encrypted according to a second encryption protocol such as an AES protocol. A user selects a desired video through a server coupled to the database. Upon payment and selection by the user, a manager provides the a first key to the database so that the first encryption may be stripped from the selected video. The server couples to a remote content key server to obtain a second key to remove the second type of encryption. The resulting decrypted digitized video may then be burned to a DVD disc for distribution to the user.Type: GrantFiled: October 11, 2008Date of Patent: June 24, 2014Inventors: David L.

Patent number: 8010790Abstract: A block-level storage device is provided that implements a digital rights management (DRM) system. In response to receiving a public key from an associated host system, the storage device challenges the host system to prove it has the corresponding private key to establish trust. This trust is established by encrypting a secure session key using the public key. The host system uses its private key to recover the secure session key. The storage device may store content that has been encrypted according to a content key. In addition, the storage device may encrypt the content key using the secure session key.Type: GrantFiled: September 10, 2008Date of Patent: August 30, 2011Assignee: DPHI, Inc.Inventors: Lane W. Lee, Randal C. Hines, Mark J. Gurkowski, David L. Blankenbeckler
