  • Access and control system for network-enabled devices
    Publication number: 20060277314
    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.

  • Enhanced nondestructive holographic reconstruction
    Patent number: 4953924
    Abstract: A method for promoting enhanced nondestructive reconstruction of holograms recorded in photorefractive media involves control of the polarization states of the reconstruction beam and the recording beams, control of the cummulative recording energy, and use of a relatively high external field applied across the media during recording which is subsequently reduced during reconstruction. The resulting reconstruction history characteristics are selectively tailored by adjusting the polarization and intensity of the reconstruction beam, the recording geometry, and the applied voltage during reconstruction and recording, and various other parameters. In general, the reconstruction efficiency starts at a relatively high level, initially reduces, and then subsequently grows above the starting value, and can be made substantially nondestructive over a typical reconstruction cycle, with erasure times exceeding forty-five minutes.

  • Methods and systems for a portable data locker
    Patent number: 10645091
    Abstract: The embodiments provide for binding files to an external drive, a secured external drive, or portable data locker. The files are bound in order to help restrict or to prevent access and modification by certain computers or users. Computers or users that are authorized or within the authorized domain are permitted full access. The files stored on the external drive may be bound in various ways. The files may be encapsulated in a wrapper that restricts the use and access to these files. The bound files may require execution of a specific application, plug-in, or extension. A computer may thus be required to execute program code that limits the use of the secured files. In one embodiment, the external drive provides the required program code to the computer. In other embodiments, the required program code may be downloaded from a network or provided by an external authority.

  • DIGITAL RIGHTS MANAGEMENT SYSTEM TRANSFER OF CONTENT AND DISTRIBUTION
    Publication number: 20130268759
    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.

  • Enhanced surface plasmon resonance sensor using Goos-Hänchen effect
    Patent number: 7327445
    Abstract: An improved surface plasmon resonance (SPR) sensor is provided based on direct measurement of the Goos-Hänchen effect. Sensor sensitivity is enhanced by selecting the thickness of the metallic layer of the SPR sensor to be close to a critical thickness dcr where the effect of the surface plasmon resonance on the Goos-Hänchen shift is most pronounced. Overall sensor sensitivity is surprisingly found to improve with this approach, even though the measurement is based on a second order effect (i.e., the Goos-Hänchen shift) instead of the first order reflectance change measured in conventional SPR sensor approaches. The invention is also applicable to sensors based on measurements of other non-specular reflection parameters, such as temporal shifts, frequency shifts, and/or angular shifts.

  • Digital rights management system and methods for provisioning content to an intelligent storage
    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.

  • Encrypted holographic data storage based on orthogonal phase code multiplexing
    Patent number: 5940514
    Abstract: An encryption method and apparatus for holographic data storage are disclosed. In a system using orthogonal phase-code multiplexing, data is encrypted by modulating the reference beam using an encryption key K represented by a unitary operator. In practice, the encryption key K corresponds to a diffuser or other phase-modulating element placed in the reference beam path, or to shuffling the correspondence between the codes of an orthogonal phase function and the corresponding pixels of a phase spatial light modulator. Because of the lack of Bragg selectivity in the vertical direction, the phase functions used for phase-code multiplexing are preferably one dimensional. Such phase functions can be one-dimensional Walsh functions. The encryption method preserves the orthogonality of reference beams, and thus does not lead to a degradation in crosstalk performance.
