ENCRYPTION TO LIMIT DIGITALLY ALTERED IMAGING DATA
20220067129 · 2022-03-03 ·

Systems, methods, and software described herein manage the verification of video data from end user computing elements. In one implementation, a computing element obtains a frame of video data from a video source. Once received, the system applies at least one encryption key or hash to the frame to encode authentication information for the video data in the frame and communicates the frame with the encoded authentication information to a video processing system.

Systems and Methods for Distributing Content Using a Common Set of Encryption Keys

Systems and methods for performing adaptive bitrate streaming using alternative streams of protected content in accordance with embodiments of the invention are described. One embodiment of the invention includes a processor, and memory containing a client application. In addition, the client application configures the processor to: request a top level index file identifying a plurality of alternative streams of protected content, where each of the alternative streams of protected content are encrypted using common cryptographic information; obtain the common cryptographic information; request portions of content from at least the plurality of alternative streams of protected content; access the protected content using the common cryptographic information; and playback the content.

Method for reading a video stream
11153624 · 2021-10-19 · ·

This method for reading a video stream comprises a step of comparing a datum characteristic of a behavior of a user with a set of predetermined thresholds, each of which, when it is crossed, characterizes an abnormal behavior of the user, a step of signaling an abnormal behavior if at least one predetermined part of these thresholds is crossed, and, otherwise, the absence of this signaling of an abnormal behavior, and a step of executing a counter-measure which makes it more difficult or impossible to access the set of information items contained in a first baseband video stream on the basis of various proofs of a second baseband video stream composed by a first terminal, this execution step being triggered automatically in response to the signaling of an abnormal behavior and not being triggered in the absence of this signaling of an abnormal behavior.

Content distribution pipeline watermarking

Methods, computer-readable media, and devices for tracking an accessing of a media content via a watermark embedded by a network node are disclosed. For example, a processing system including at least one processor may receive, from a first network node, a first copy of a watermark that is embedded by the first network node in a media content. The processing system may further receive a notification comprising a second copy of the watermark and an identification of a first endpoint device, the notification associated with an accessing of the media content by the first endpoint device, and record the accessing of the media content by the first endpoint device.

INSERTING SECONDARY CONTENT IN PRIMARY CONTENT IN IPTV
20210227296 · 2021-07-22 ·

The invention is concerned with insertion of secondary content in a time slot of primary content. The primary content and the secondary content are provided to a receiver via a managed content delivery network configured for IPTV delivery. The secondary content may be personalized content, such as an ad. Both the primary content and the secondary content may be encrypted, and decryptable with different decryption keys. Measures are described for pre-caching the decryption key for the secondary content at the receiver ahead of a scheduled play-out time of the secondary content. By pre-caching the decryption key, an interruption in play-out may be avoided or reduced compared to a basic scenario in which the receiver requests the decryption key at or immediately before the scheduled play-out time.

CAPTURE AND PRESENTATION OF AUTHENTICATED DATA

Techniques for continuous authenticity for captured data are provided. Data in form of analog or digital media including videos, images, and audio recordings, and sensed, detected, measured, observed, or otherwise recorded data may be authenticated with source information upon capture. The chain of custody of the authentication may be preserved throughout processing and distribution of the captured data through a distribution network assuring consumers of the data that data or source information for the data is not altered in any way or, if altered, it is done so for the purpose of preserving the authenticity of the data and reversing the process will render an unaltered version of the original data set. In some examples, the authentication and/or capture of data may be triggered by a predefined event to ensure data associated with the event is captured and preserved with authentication.

CONTENT RECOGNITION SYSTEMS AND METHODS FOR ENCRYPTED DATA STRUCTURES
20210119792 · 2021-04-22 · ·

A system for maximizing storage of encrypted content in a storage system includes one or more processors; and a storage medium storing instructions. When executed, the instructions may configure the one or more processors to: receive, from a first client device, a first data structure encrypted commutatively with a first key and a common key, the receiving system lacking access to the common key; receive the first key and a first segment identifier; receive, from a second client device, a second data structure encrypted commutatively with a second key and the common key; receive a second segment identifier; using the first key, partially decrypt the first data structure; storing the partially decrypted first data structure; and selectively storing a copy of the second data structure based on whether content of the first data structure corresponds to content of the second data structure.

Mediating between host and display where a mediator enforces security policy over bidirectional protocols of a Display Data Channel (DDC) of video communication protocols between host and display, where AD-EDID display emulators are coupled to DDCs of the host's video port, AD-EDID host emulators are coupled to DDCs of display's video port and security enforcing communication units couple between pairs of AD-EDID display emulator and AD-EDID host emulator, where AD-EDID display emulators emulate display operation and behavior over the DDC, AD-EDID host emulators emulate host operation and behavior over the DDC and security enforcing communication units enforce security policy such as unidirectional communication between the pairs of AD-EDID host emulators and AD-EDID display emulators.

On-demand generation and personalization of video content

Various embodiments for dynamically generating an advertisement in a video stream are disclosed. In one embodiment, video stream content associated with a video stream for a user device is received. Video analytics data is obtained for the video stream content, which indicates a scene recognized in the video stream content. An advertisement to be generated and inserted into the video stream content is then selected based on the scene recognized in the video stream content, and an advertisement template for generating the selected advertisement is obtained. Video advertisement content corresponding to the advertisement is then generated based on the advertisement template and the video analytics data. The video advertisement content is then inserted into the video stream content, and the modified video stream content is transmitted to the user device.
