Abstract: One embodiment takes the form of a method and apparatus for sharing a purchased pay-per-view (PPV) event over a plurality of set-top boxes (STB). Thus, a PPV event purchased through one STB may be viewed through every STB associated with the customer ID number of the purchaser, including an STB located in a separate location from the PPV purchaser. The customer information used to locate the STBs associated with the customer ID may be retrieved from a database or may be provided by a billing site. Providing for the purchaser to view the PPV event on several STBs may allow the customer of the PPV service maximum access to the purchased PPV event.

Abstract: A media distribution network device connects to an online collaborative session between a first participant network device, a second participant network device, and a security participant network device. The security participant network device is configured to decrypt packets of the online collaborative session to apply security polices to the packets. An encrypted packet is received at the media distribution network device. The encrypted packet is received from the first participant network device containing data to be distributed as part of the online collaborative session. The encrypted packet is distributed to the security participant network device prior to distributing the encrypted packet to the second participant network device.

Abstract: In an approach, a target computing device receives a pairing request from a controller computing device, the pairing request including controller credentials that were previously received by the controller computing device from an authentication server computer and encrypted under a service key. The target computing device forwards the pairing request to the authentication server, the authentication server computer being configured to return a pairing response based at least in part on the controller credentials. The target computing device receives the pairing which includes a shared secret encrypted under a target device key and the same shared secret encrypted under a controller key. The target computing device decrypts the shared secret encrypted under the target device key and forwards the shared secret encrypted under the controller key to the controller device. Using the decrypted shared secret, the target computing device establishes a secure connection to the controller computing device.

Abstract: This invention relates to a network interface device. A first capture device interfaces with a first external information source to capture first external information. A processor processes the captured first external information and stores it in a first media. The processor initiates the storage of the first captured information at an initial time and completes storage of the first captured information at a completion time, thus providing a stored defined set of first captured information. A transmitter transmits the defined set of stored captured information to a remote location on a network. A remote processing system is disposed at the remote node on the network and includes a database and a receiver for receiving the transmitted defined set of first captured information. A data converter is operable to convert the received defined set of first captured information to a second format. The database stores the set of converted captured information.

Abstract: Methods, devices, systems and computer program products enable generation, distribution and management of live broadcast content in such a way so as to allow identification of a pirate device or subscriber quickly and efficiently. Content is divided into content blocks, where each content block is divided into content units. Each of the content units is selectable from n variations of the content unit and a majority of ail possible combinations of content unit variations are permissible to be selected for production of the uniquely identifiable content. The content blocks, including the n variations of the content units, a media block key, and at least one device key is delivered to an authorized device. A particular pattern of content units is generated that identifies which of the n content unit variations must be used by the authorized device for constructing each content block.

Abstract: A method implemented by a set top box that encrypts communications for a channel stacking switch (CS) using a public key of the CSS, the method comprising: obtaining a message from a head end; extracting electronic counter measure (ECM) data from the message; sending the ECM data to the CSS; receiving, in response to the sending, a new public key of the CSS; encrypting communications for the CSS using the new public key of the CSS. Also, a method for implementation by a CSS, comprising: maintaining a private key and a public key; obtaining ECM data sent by a set top box in communication with the CSS; obtaining an identifier of the CSS; formulating a new public key based on the private key, the identifier and the ECM; rendering the new public key available to the set top box.

Abstract: A method for execution by a computing device of a dispersed storage network (DSN). The method begins by encrypting a data segment of a data object using a security key to produce an encrypted data segment. The method continues by dispersed storage error encoding the encrypted data segment to produce a set of encoded data slices and sending the set of encoded data slices to storage units of the DSN for storage. The method continues by encrypting the security key using an encryption key to produce an encrypted security key and dispersed storage error encoding the encrypted security key to produce a set of encoded key slices, wherein a decode threshold number of encoded key slices is needed to recover the encrypted security key. The method continues by sending the set of encoded key slices to a set of storage units of the DSN for storage therein.
