    摘要： Systems and methods for precision downstream synchronization of digital streaming content on an edge content processor in the absence of access to pixel-level data by a video player app operative on the edge content processor are disclosed. Encrypted video streams are synchronized to unencrypted video streams using acquired knowledge of the edge content processor's latency, i.e., the time elapsed between a command to render a video frame and that frame being displayed by the edge content processor. Once a predicted time of display of an encrypted video is obtained by a video player app operative on the edge content processor, a corresponding RGBA video frame is delayed by an amount of time equal to that predicted time minus the edge content processor's latency before a command to render it is issued by the video player app, thereby ensuring both frames are displayed simultaneously.

    摘要： A method, apparatus and system for processing a live broadcast information stream are provided. The method includes: obtaining an encryption permission recognition result by recognizing an encryption permission for a target live broadcast room in response to a live broadcast request of the target live broadcast room sent by an anchor client; generating an encryption live broadcast indication and a stream pushing address of the target live broadcast room in response to the encryption permission recognition result indicating that the target live broadcast room is an encrypted live broadcast room, in which the encryption live broadcast indication is used to instruct a live broadcast source station to encrypt live broadcast information stream of the target live broadcast room; and sending the stream pushing address corresponding to the target live broadcast room to the anchor client, in which the stream pushing address indicates an address of the live broadcast source station.

    摘要： A system for providing a second screen experience to an end user is disclosed. The system may include a first media device including one or more processors configured to receive a broadcast signal encoded with steganographic metadata, extract a payload from the steganographic metadata, and transmit a steganographic metadata signal, the steganographic metadata signal including the extracted payload. The system may further include a second media device including one or more processors configured to receive the steganographic metadata signal from the first media device, determine one or more data identifiers within the received steganographic metadata signal, and execute one or more actions based on the one or more data identifiers.

    摘要： A method of authenticating data received from a user device by a service provider may include receiving user credentials from the user device via a secure communication channel; upon verifying the user credentials, providing to the user device via the secure channel a permission token, where the permission token includes at least a shared secret, where a data within the permission token is not observable to the user device and a shared secret data outside the data of the permission token, the shared secret data observable to the user device; and receiving a request from the user device via a non secure communication channel, where the request may include at least the permission token and a hash digest formed using at least a portion of the shared secret data.

    摘要： Aspects of the subject disclosure may include, for example, a processing system that performs operations including collecting encrypted network traffic flow data from user interaction with an application, deriving a first set of traffic feature vectors from the encrypted network traffic flow data collected, training a machine learning algorithm on the first set of traffic feature vectors to classify each traffic feature vector in the first set of traffic feature vectors as associated with a type of the application or not associated with the type of the application, and classifying whether an encrypted network traffic flow as the type of the application by applying the machine learning algorithm to a traffic feature vector of the encrypted network traffic flow. Other embodiments are disclosed.
