A content distribution system includes content receivers that provide a plurality of blockchain databases that store transaction records associated with subscriber requests for content, and a computer system that processes those transaction records and enables authorized content receivers to output requested content.

A system and method for records management and classification of files in a content management system having a server system that stores the files. A system detects when at least one of the files is classified by a user of a client computing system as a classified file, and based on the detecting of the classification of the one or more files, each classified file is removed from the client computing system. The system further detects when at least one of the files is declared as a permanent record by the user of the client computing system, and based on the detecting of the declaration as a permanent record, prevents editing by the client computing system of each file declared as a permanent record.

A transaction platform including at least one or more public, public-private and/or private distributed ledgers or blockchains that together enable the secure effectuation and recordation of one or more transactions while maintaining transaction party confidentiality. The private distributed ledgers or blockchains are able to store, maintain and provide information about the parties related to the transactions which the distributed blockchains or databases are able to utilize in order to securely and quickly validate, execute and record the transactions in a manner that is GDPR and other data privacy law complaint.

An authorized user obtains a packaging license that grants permission to use a particular recording device to generate multimedia content in accordance with specified license terms. The packaging license includes a content key that is used to encrypt the multimedia content at the point of capture on the recording device. The encrypted multimedia content can be transmitted via unsecure channels (for example, via electronic mail) to a networked content repository or an intended recipient. For playback, an authorized user obtains a playback license that grants permission to decrypt and playback the multimedia content using a particular playback device. An authorization server and a key management server are used to manage which users are entitled to receive a license, and to define the terms of the granted licenses. A record of the granted authorizations and licenses is maintained, thereby allowing access to a given content item to be audited.

Apparatuses, methods and storage medium associated with single pass parallel encryption are disclosed herein. In embodiments, an apparatus for computing may comprise an encryption engine to encrypt a video stream. The encryption engine may comprise a plurality of encryption pipelines to respectively encrypt a plurality of video sub-streams partitioned from the video stream in parallel in a single pass as the video sub-streams are being generated. The plurality of encryption pipelines may use a corresponding plurality of multi-part encryption counters to encrypt the corresponding video sub-streams as the video sub-streams are being generated. Each of the multi-part encryption counters used by one of the encryption pipelines may comprise a sub-portion that remains constant while encoding the corresponding video sub-stream, but the sub-key is unique for the one encryption pipeline, and differs from corresponding sub-portions of the multi-part encryption counters used by the other encryption pipelines. Other embodiments may be disclosed or claimed.

Techniques and a system are provided for protecting content (or media item) streamed over a network from unauthorized access. As an example, the streaming protection system generates statistics when a client requests a media item. The statistic may be generated based on various factors. The media item is divided into different portions, each portion requiring a different key to decrypt the portion so that it may be viewed by a user. Based on the generated statistic, the streaming protection system determines whether or not to allow the client access to the decryption key for a portion of the media item.

A system comprising a plurality of peer caches associated with a corresponding plurality of content owners; shared ledger logic having a channel for each content owner of a plurality of content owners, the shared ledger logic to maintain a shared ledger data structure and to perform the operations of: in response to receipt of a first content title, responsively recording a first ledger entry for the first content title which is visible to a first content owner which owns the first content title; receiving an encryption key from the content owner, wherein the first content title comprises an encrypted content title encrypted with the key; storing the encrypted content title on one or more network storage devices; and when the encrypted content title reaches an edge cache, using the key to decrypt the encrypted content title and updating the first ledger entry to identify the edge cache.

A trusted branded email method and apparatus in one aspect detects branded electronic messages and performs validation before it is sent to a recipient. In another aspect, an electronic messages is branded by embedding branding assets and validation signatures. Algorithms that generate validation signatures are dynamically selected to further strengthen the security aspects. Branding assets are presented to a user using a distinct indicia that represents to the user that the branding assets are secure.

Systems and methods for tracking media file playback are provided. A request to upload a media file and metadata associated with the media file is received. Next, the media file and metadata is uploaded via a blockchain protocol. Next, a request to play the media file is received from a client device or a digital service provider (DSP) platform. The request to play the media file is validated via the blockchain protocol. Upon validating the request to play the media file, the media file is transmitted for playback at the client device or DSP platform. Last, the number of times the media file is played is tracked via the blockchain protocol.

Exemplary embodiments relate to techniques for sending ephemeral content messages via a communications service. An interface may be presented to allow a user to initially access ephemeral content functionality and select content for inclusion in the ephemeral content message. The interface may present a streamlined set of use cases without regard to the manner in which the content was initially captured. Different types of content may be used as ephemeral content, including images, videos, weather reports, news stories, text, audio recordings, location tags, etc. The ephemeral content may be sent through the communications service as an end-to-end encrypted message. When a user replies to an ephemeral content message, the reply may trigger a one-to-one conversation between the originating user and the replying user. Alternatively, an ephemeral content message may be initially sent to a selected group, and replies may be sent back to the entire group.
