  • Patent number: 8914634
    Abstract: 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.

  • Patent number: 8831218
    Abstract: 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.

  • Patent number: 8831217
    Abstract: The present invention relates to accessing content stored on a storage device and protecting the content with a digital rights management (DRM) scheme. The storage device may be a disk drive, or network attached storage. The storage device can perform cryptographic operations and provide a hardware root of trust. The DRM employs a binding key, a content key, and an access key. The binding key binds the content to the storage device and is based on a key concealed on the storage device. The binding key itself is not stored anywhere on the storage device. The content key is a key assigned to the content. The access key is determined based on a cryptographic combination of the content key and binding key. In one embodiment, the content is encrypted based on the access key and stored in encrypted form in the storage device.

  • Patent number: 8793374
    Abstract: Applications, systems and methods for permitting simultaneous use of a file by two or more computers over a network may include storing the file locally in a local storage device associated with a local computer; providing access to the file by at least one remote computer which is connectable to the local computer via the network, and wherein at least one of the computers is connectable to the network through a firewall element. The file may be stored in at least one remote storage device associated with the at least one remote computer, respectively, and versions of the file contained on the one or more remote storage devices are synchronized with that on the local device by transmitting over the network connecting the one or more remote storage devices with the local device, at least one of Delta files and Inverse Delta files between the remote storage devices and the local storage device.

  • Publication number: 20130266137
    Abstract: 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.

  • Patent number: 8374068
    Abstract: A low cost and lightweight interchangeable lens system is provided. The lens system includes two aspheric elements that is usable both for page-based and bit-based data storage systems. The lens system has a large field of view up to ±50 degrees and a high numerical aperture up to 0.8. The invention reduces cost and weight of the objective lenses and is usable with the servoing technology. The invention provides a long working distance of 20% of the focal length and provides sufficient physical space to accommodate media and aberration corrections, which enable a media interchangeable and compatible system among the both optical recording formats.

  • Patent number: 8352567
    Abstract: An apparatus, method and service model are disclosed which simplify conventional methods for schedule recordings of television programs and enable users to control recording equipment from any location via the Internet. Entities connected to computer networks such as the Internet and web-browser software can schedule recordings of television programs and/or operate the recording equipment. In an example scenario, a user who maintains recording equipment at home may utilize the present invention from his or her workplace or vacation place, accesses a service provider website using her/his user name and password, views the a schedule of television programs provided by a broadcaster or other distributor of programming and selects the television programs to be recorded. The application service provider in turn transmits the selected television program information to a computer connected to a later described remote control unit to execute and operate the recording of selected programs.

  • Patent number: 8341275
    Abstract: Systems and methods for remote access of network-enabled devices that provide seamless, firewall-compliant connectivity between multiple users and multiple devices, that allow collaborative operations by multiple users of remote devices, that allow point to multipoint control of multiple devices and which allow rapid, secure transmission of data between remote users and devices. In general terms, the system includes at least one connection server, and at least two computers operatively coupled to the connection server via a public or global network. In an example where at least one client computer is operatively connected to at least one network-enabled device through a connection server via the public or global network, the connection server is configured to route control instructions from the client to the network-enabled device, and route data from the network-enabled device to the client.

  • Patent number: 8196217
    Abstract: Transmission efficiency and/or spatial resolution provided by resonant apertures can be enhanced by disposing a tip on part of the screen that extends laterally into the aperture. For example, a tip disposed on the ridge of a C-shaped aperture can dramatically improve performance. A spatial resolution of ?/50 has been experimentally demonstrated with this approach. The combination of high spatial resolution and high transmission efficiency provided by this approach enables many applications, such as near field optical probes for near field scanning optical microscopy (NSOM). Another application is high resolution electron sources, where an photoelectron emitter can be disposed at or near a tip+aperture structure such that the high resolution optical near-field provides a correspondingly high resolution electron source.
