  • Patent number: 8954752
    Abstract: A method and structure for enhancing protection for at least one of software and data being executed on a computer. A file to comprise a secure object is constructed, using a processor on a build machine, the secure object to be executed on a target machine different from the build machine. The secure object comprises at least one of code and data that is to be encrypted when the secure object is stored on the target machine. The encrypted stored secure object is decrypted by the target machine when executed by the target machine after retrieval from a memory on the target machine. The decryption uses a system key of the target machine. The secure object is stored, upon completion of construction, in an encrypted state as a completed secure object, and the secure object is completed without the build machine having the system key of the target machine.

  • Patent number: 8934627
    Abstract: Generating a still image from a sequence of video frames comprises the steps of receiving a sequence of video frames and storing a predetermined number of the sequence of video frames temporally adjacent to an user initiated capture event, the predetermined number of frames being defined as a cliplet. Video capture is performed using cliplets, which are short video segments, preferably in compressed data format. A crop-and-process instruction is added to the cliplet. All processing, handling or storage of the data is cliplet based. Editing instructions are stored with the cliplet allowing editing to be performed by a user at one resolution and then re-performed at a higher resolution at a server where it is printed. Modified reprints of an image can be obtained without resending the images and adequate storage for the cliplets can be assured. Encryption of the cliplets during transmission and storage is facilitated by cliplet-based processing.

    Abstract: A switcher device comprises a multiplexer coupled in-between at least one input and output cards. The multiplexer detects the presence of an event signal from an activated sink. In response to the detection of the event signal, a processor changes an address of an HDCP receiver from a first address to a second address for enabling the at least one source to authenticate with the input card and enabling the output card to authenticate with the at least one sink for security protocol encryption. In response to the non-detection of the event signal, the processor changes the address of an HDCP receiver from the second address to the first address for disabling the at least one source from initiating a first authentication with the input card, therefore the output card also does not attempt to initiate a second authentication with the at least one sink for security protocol encryption.

  • Patent number: 8903091
    Abstract: A secure optical communication system and method are disclosed. Short optical pulses are first modulated with data, then dispersed in time so that they spread out over multiple bit periods, then the desired code is applied to the dispersed pulses. The encoding may include frequency shifts or phase shifts or other. The dispersed optical symbols overlap in time so an applied code chip thus acts on multiple symbols simultaneously. There are generally multiple code chips per dispersed symbol. The coding device does not need to be synchronized to the data rate. Multiple wavelength division multiplexed channels may be encoded simultaneously. The signal propagates to a decoder that is synchronized with encoder to apply a complementary code thereby canceling out the effect of the encoder. The encoder and decoder can be realized by varying the wavelength of an optical pump to a parametric amplifier, allowing for a wide-band frequency shift.

    Abstract: A method operational on a receiver device for exchanging and/or generating security keys is provided. A first encrypted master key Km is received at the receiver device from a transmitter device, the first encrypted master key Km secured by a receiver public key Kpub-rx. The first encrypted master key Km may be decrypted with a receiver private key Kpri-rx to obtain the master key Km. The master key Km may be encrypted using a block cipher that applies a receiver secret key Kh to obtain a second encrypted master key.

  • Patent number: 8837908
    Abstract: Systems and methods for performing secure playback of media content are described. One embodiment, among others, is a method for performing secure playback of video in a hardware protection module. The method comprises receiving media content from a media player comprising video data, audio data, and navigation data. The method further comprises receiving digital rights management (DRM) information relating to the media content, removing a portion of the video data from the media content, forwarding the audio data, navigation data, and a remaining portion of the video data to the media player for decoding, and decoding, in the hardware protection module, the portion of the video data.

  • Patent number: 8838977
    Abstract: Methods, devices, and computer program products facilitate the application of a content use policy based on watermarks that are embedded in a content. Watermark extraction and content screening operations, which can include the application of content usage enforcement actions, may be organized such that some or all of the operations can be conducted at different times by different devices. The watermark extraction results can be stored in a secure location and accessed by other devices at different times. These operations can be conducted by one or more trusted devices that reside in a home network. The home network can also include a gateway device that can coordinate the operations of the various network devices and/or delegate the various watermark extraction and content screening operations.

  • 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: 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.
