Methods, apparatus, systems and articles of manufacture are disclosed to generate measures of unique audiences for Internet-based media. An example apparatus disclosed herein includes at least one memory, instructions, and at least one processor. The processor to execute the instructions to: receive first HyperLogLog (HLL) data from a first server of a first database proprietor and second HyperLogLog (HLL) data from a second server of a second database proprietor, the first HLL data including obfuscated first user impression data and the second HLL data including obfuscated second user impression data; generate union HLL data based on the first HLL data from the first database proprietor and the second HLL data from the second database proprietor by performing a union of data sets of the obfuscated first user impression data represented in the first HLL data and the obfuscated second user impression data represented in the second HLL data; and determine a total number of deduplicated unique audience members based on the union HLL data generated by the vector analyzer.

Techniques for media content tamper protection and detection are described. In some embodiments, the protection method is performed at an encoder. The encoder obtains a first sequence of signatures within a group of pictures and a second sequence of signatures for audio frames corresponding to the group of pictures. The encoder then combines the first sequence of signatures and the second sequence of signatures to generate a combined signature, and the combined signature is then embedded in a transport stream for transmission to a client device. In some embodiments, the detection method is performed at a client device, where the client device, in response to detecting a first message in the transport stream, starts calculation of signatures for a group of pictures and corresponding audio frames. The client device then uses the calculated signatures to validate an expected signature for the group of pictures and the corresponding audio frames.

Systems and methods for generating certified images and incident reports are disclosed. An image capture device can be used to capture an image and integrate metadata from camera sensors as well as other ancillary device sensors into the image. The image and its metadata can then be certified upon a check that the image and its metadata are authentic and unaltered. The image and its metadata can then be included in or as a part of an incident or other report describing an incident or event such as an accident or a crime. The image and/or incident report may be maintained at a cloud-based server for viewing, authorized editing, and subsequent distribution.

The systems and method disclosed herein address introduce identifiers within the individual entitlement management messages (EMMs) addressed to that client that uniquely identify the combination of system and subscriber account to which the client is deployed, and use of them to issue automatic ‘factory reset’ behavior when the client is re-authorized for the new subscriber. In one embodiment, the EMM messages used to trigger the reset behavior are cryptographically signed specifically for the individual client to ensure that such a message cannot be maliciously sent by an untrusted third party. The facility to deliver such a message is already available within the conditional access system (CAS).

An example apparatus disclosed herein includes at least one memory, instructions, and at least one processor to execute the instructions to: receive first HyperLogLog (HLL) data from a first server of a first database proprietor and second HyperLogLog (HLL) data from a second server of a second database proprietor, the first HLL data including obfuscated first user impression data and the second HLL data including obfuscated second user impression data; generate union HLL data based on the first HLL data from the first database proprietor and the second HLL data from the second database proprietor by performing a union of data sets of the obfuscated first user impression data represented in the first HLL data and the obfuscated second user impression data represented in the second HLL data; and determine a total number of deduplicated unique audience members based on the union HLL data generated by the vector analyzer.

Embodiments of mechanisms for dynamic media content type streaming management for mobile devices are generally described herein. In some embodiments, the mobile device may receive selection input pertaining to generating output from a media file containing at least two of audio data, video data, and closed-captioning data, the selection input selecting at least one of audio, video, and closed-captioning to be output during play of the media content. In some embodiments, the mobile device may generate an audio output as a signal in response to the selection input including audio. In some embodiments, the mobile device may generate a video output as a signal in response to the selection input including video. In some embodiments, the mobile device may generate a closed-captioning output as a signal in response to selection input including closed-captioning.

Methods and apparatus for control of data and content protection mechanisms across a network using a download delivery paradigm. In one embodiment, conditional access (CA), digital rights management (DRM), and trusted domain (TD) security policies are delivered, configured and enforced with respect to consumer premises equipment (CPE) within a cable television network. A trusted domain is established within the user's premises within which content access, distribution, and reproduction can be controlled remotely by the network operator. The content may be distributed to secure or non-secure “output” domains consistent with the security policies enforced by secure CA, DRM, and TD clients running within the trusted domain. Legacy and retail CPE models are also supported. A network security architecture comprising an authentication proxy (AP), provisioning system (MPS), and conditional access system (CAS) is also disclosed, which can interface with a trusted authority (TA) for cryptographic element management and CPE/user device authentication.
