A system and method are presented for content control and monitoring in a multi-party video stream using a specialized user interface (UI). Particular participants are identified as luminaries and allowed to specify off-limit topics. Other participants are presented UIs that require agreement to avoid off-limit topics. All participants are immediately able to report problem behavior during the stream through the provided UI. Reports made through this interface immediately result in quarantining compensation and streaming content including reports relating to the off-limit topics. Administrative UIs allow for quicker understanding of the reporting issues, quicker review of the potentially offending stream, and quicker resolution of the report.

A system and method are presented for the creation and management of live audio-visual streams between multiple parties. An organizing computer system requests a system server to establish a stream with a limited, preset number of slots. Other computer systems request to join the stream. Once the present number of slots is filled, a queue is established for waiting computer systems. Participating computer systems can be limited in their participation to a present time period, after which they are removed from the streams. Removal of one computer system from the stream opens a slot for another, which is filed from the queue of waiting computer systems. The queue can be sorted through a variety of means, including FIFO and auction.

Methods and apparatus to identify media based on watermarks across different audio streams and/or different watermarking techniques are disclosed. Example apparatus disclosed herein include a watermark detector to detect a first watermark embedded in a first audio stream, the first watermark including a first source identifier and a first timing identifier, and detect a second watermark embedded in a second audio stream, the second watermark including a second source identifier and a second timing identifier. The disclosed example apparatus also include a controller to associate the first and second watermarks with a media detection event when both (1) the first and second source identifiers match and (2) the first and second timing identifiers are chronologically congruent. The disclosed example apparatus further include a transmitter to transmit the media detection event to a data collection facility.

A security-monitoring system includes a data-collection module, a security-monitoring module and an attack-detection module. The data-collection module can collect data associated with a data stream. The security-monitoring module monitors a number of activities within a device. The attack-detection module can detect one or more attacks on the device based on the monitored plurality of activities by using one or more trusted processors. The collected data includes one or more security parameters associated with the data stream. The attack-detection module identifies the attacks based on the security parameters and data from the one or more trusted processors.

Systems and methods for providing a mechanism for a computer user to seamlessly and readily access information that may be supplied by a number of different sources.

Providing a conditional access system (CAS) to a set-top box is described. An example method includes encapsulating a CAS application in a NCAS (Next CAS) container, and objects associated with the CAS application are executed in the NCAS container. Resources for the CAS application and other applications running on the set-top box are pre-allocated so that each application has a pre-fixed resource allocation upon startup of the set-top box. An execution of the CAS application is validated using a linked chain of trust.

In one illustrative example, TV usage data associated with a residential set-top box (STB) are obtained and stored over a plurality of repeated (e.g. weekly) time periods. TV usage pattern data associated with the residential STB are derived based on the stored TV usage data. A suspected illegitimate use of the residential STB is identified based on identifying a match or correlation between the TV usage pattern data and one of a plurality of predetermined commercial TV usage patterns. Further, for each listing data of one or more published listings of business hours, types, and themes associated with one or more commercial establishments, a comparison or correlation is performed between the TV usage pattern data and the listing data. A commercial establishment associated with illegitimate use is identified based on identifying a match or correlation between the TV usage pattern data and the listing data associated with the commercial establishment.

Motion pictures or other digital media content can be encoded with visible, yet obscured, digital codes that can be optically detected by a camera or other automated image processing device. If a code is recognized in captured media content, further capture, playback and/or distribution can be halted, as desired. Because the code is visible (albeit hidden) in the digital imagery itself, capture by another camera or other optical device will not typically negate the usefulness of the code. That is, the code is visibly present within the imagery itself, so subsequent capture of the video imagery will also capture the code, thereby allowing for detection and/or prevention.

Methods and apparatus to identify media based on watermarks across different audio streams and/or different watermarking techniques are disclosed. An example apparatus includes a watermark detector to detect a first watermark embedded in a first audio stream associated with media and to detect a second watermark embedded in a second audio stream associated with the media. The second audio stream is different than the first audio stream. The example apparatus includes a watermark analyzer to compare first media identifying information in the first watermark with second media identifying information in the second watermark. The example apparatus also includes a media detection event controller to associate the first and second watermarks with a media detection event when the first media identifying information is consistent with the second media identifying information. The example apparatus further includes a transmitter to transmit the media detection event to a data collection facility.

Techniques are disclosed for defensive routing of guard wires for security-critical wires in an integrated circuit (IC). Defensive routing provides a routing-centric and preventive layout-level defense against IC fabrication time attacks against security-critical wires within an IC. An example methodology implementing the techniques includes identifying at least one security-critical wire in an IC design, identifying at least one unblocked surface of the identified at least one security-critical wire, and guarding the identified at least one surface of the identified at least one security-critical wire with a guard wire. In one example, the guard wire may be a natural guard wire. In another example, the guard wire may be a synthetic guard wire.
