Techniques and mechanisms described herein facilitate the management of digital rights for media content item presentation. According to various embodiments, a request for a content decryption key may be received at a media application implemented at a computing device. The request may be transmitted by a media content player implemented at the computing device. The request may be transmitted in accordance with a designated key exchange protocol. A license for an encrypted media content item corresponding with the requested content decryption key may be identified at the media application. Based on information included in the license, encrypted key material may be decrypted to create the requested content decryption key via a processor at the computing device. The requested content decryption key may be provided to the media content player.

Example embodiments provide systems and methods for securing a deployed camera. A security apparatus is coupled to the deployed camera and accesses video content from the coupled camera. The security apparatus accesses video content from the coupled camera, splits the video content within a plurality of RTP packets, encrypts payloads of the RTP packets, embeds in a header of the encrypted RTP packets, at least two key identifications for decryption of the encrypted RTP packets, and transmits the plurality of RTP packets over a network to a video management system.

Methods and systems for securing data using random bits and encoded key data. A plurality of true random number generator (TRNG) disks and a plurality of key data sets are provided. A key data set from the plurality of key data sets is associated with each of the plurality of TRNG disks, respectively. The key data set comprises at least a block of random bits of an associated TRNG disk. An encoded key data set is formed by encoding at least two of the key data sets together. The source data can be encrypted with the encoded key data set to produce a quantity of encrypted data. The encrypted data can be decrypted with the encoded key data set or the at least two of the key data sets retrieved from the associated TRNG disks.

A method and system for managing adaptive bitrate video streaming. The method including: retrieving raw data associated with a video stream traffic flow; determining at least one video chunk from the raw data of video stream traffic flow; determining parameters associated with the video chunk; determining a bitrate factor based on the parameters; determining a Quality of Experience (QoE) score based on the bitrate factor; and providing a traffic action based on the QoE score. The system including: an input module configured to retrieve raw data; an analysis module configured to determine at least one video chunk from the raw data and determine parameters associated with the video chunk and a bitrate factor based on the parameters; a QoE module configured to determine a QoE score based on the bitrate factor; and an output module configured to provide a traffic action based on the QoE score.

The present disclosure relates to a transmitting device and a transmitting method, and a receiving device and a receiving method which are capable of improving confidentiality and communication resistance in low power wide area (LPWA) communication. The transmitting device generates a key stream on the basis of GPS time information, encrypts transmitted data on the basis of the key stream to generate encrypted data, and transmits the encrypted data to the receiving device. The receiving device generates a key stream on the basis of GPS time information and decodes the encrypted data into the transmitted data on the basis of the key stream. The present disclosure can be applied to an LPWA communication system.

A method for controlling access to data by users, where a system generates a first symmetric encryption key stream and defines a number of shares of which a number is required to calculate each of said symmetric encryption keys; a sequential portions of data being symmetrically encrypted with the symmetric encryption key; the key stream data further being asymmetrically encrypted with at least one public asymmetric encryption key that is received by the system; and transmitting the asymmetrically encrypted key stream data and said first symmetrically encrypted data file or stream comprising sequential portions of encrypted data to a data storage.

Low power devices are able to utilize encryption in communication. Low power devices typically cannot send/receive large amounts of data since sending/receiving more data uses more power. Implementing a key exchange with a small encrypted payload enables secure communication between the devices. A one-way data stream is implemented. The one-way data stream is able to be encrypted.

A data transmission platform for data transmission using a blockchain is configured to receives ciphertext data from a data provider, wherein the ciphertext data include transmitted data authenticated by the data transmission platform and encrypted by the data provider; identifies a target data requestor; creates a smart contract according to a data transmission requirement of the target data requestor; uploads the smart contract to a blockchain; sends a data transmission request to the data provider; re-encrypts the ciphertext data to obtain re-encrypted data using a re-encryption key generated by the data provider; triggers the smart contract to send the data transmission demand of the data requestor to the data provider; and notifies the data requester to extract the decrypted data and perform decryption to obtain the transmitted data.

A media playback system for presenting to a user a composition of a plurality of media streams. It has a media selection component configured to receive a scenario dataset, to receive user input for selecting viewing times defining segments of media and composition selections, and to output a list of segments of media from the scenario dataset that are authorized to be viewed by the user. The system has a playback control component configured to retrieve from media storage at least the segments of media from the output list of segments, to decode the segments of media, and to compile composition instructions. The system has a media playback component configured to receive the rendered media and the composition instructions.

An improved system and method are disclosed for improving functionality in software applications. In one example, the method includes a computing entity having a network interface, a processor, and a memory configured to store a plurality of instructions. The instructions include instructions for a superblock application having instructions for a function block included therein. The function block is configured to provide functions that are accessible to the superblock application via an application programming interface (API). The functions are provided within the superblock application itself and are accessible within the superblock application without switching context to another application on the computing entity.
