Abstract: Methods and systems for managing and/or processing a blockchain to maintain data security for confidential and/or personal data are provided. According to certain aspects, the disclosed data security techniques may enable access sharing functionality utilizing the blockchain. For example, access sharing may be utilized to file documents, share policy information, and/or comply with an audit. The data security techniques disclosed herein also enable the use of smart contracts to transfer funds associated with payment obligations and/or other forms of blockchain based payments, comply with anti-money laundering requirements, report industry data, validate interest payments and/or maintain agent sales data. Data security may be achieved through the use of public key/private key encryption techniques.

Abstract: In some implementations a system can be configured to reduce the burden of pairing user devices with playback devices. For example, all users (or user devices) who commonly operate within a particular environment (e.g., a home) can be configured as authorized users of playback devices within the particular environment. When one of the authorized users pairs a user device with a playback device, all of the user devices for all authorized users can be automatically paired with the playback device as a result of the single pairing. Thus, only a single authorized user is burdened with the pairing process in order to pair all authorized users with the playback device.

Abstract: Methods and systems for managing and/or processing a blockchain to maintain data security for confidential and/or personal data are provided. According to certain aspects, the disclosed data security techniques may enable access sharing functionality utilizing the blockchain. For example, access sharing may be utilized to share policy information. The policy information may be associated with a smart contract. Accordingly, the policy information may be encrypted using a public key for the smart contract and compiled into a block of the blockchain. In response to a request to provide access to the information to a particular node, the private key for the smart contract may be encrypted using the public key for the particular node and compiled into a block of the blockchain.

Abstract: Methods and systems for processing a blockchain comprising a plurality of immutable sales records corresponding to sales made by agents of an entity are provided. According to certain aspects, a transaction request indicating a sale made by an agent of the entity may be received at a first node. A block including a sales record indicating the sale made by the agent may be added to a blockchain and transmitted to another node for validation. The first node may add the block to a copy of the blockchain, where the block may be identified by a hash value that references a previous block in the blockchain that includes at least one additional sales record.

Abstract: One embodiment provides for a media playback device comprising a memory device to store instructions; one or more processors to execute the instructions stored on the memory device, the instructions to cause the one or more processors to provide a playback queue manager to manage one or more media playback queues including a set of media items associated with a scheduled event and a playback routing manager to determine an output destination for the set of media items based on context associated with the scheduled event, the playback routing manager to route output of playback of the set of media items to one or more of multiple different connected media playback devices based on the context associated with the scheduled event.

Abstract: A holder for jigsaw puzzles, game pieces, pictures or the like that includes a stiff rectangular panel having an upper flat surface on which the pieces can be assembled, a flexible cover sheet that removably overlies the pieces on such upper flat surface of said member and a pouch for the panel. Each of the pouch and panel have a carrying handle and these are aligned with one another when the panel is fully inserted into the pouch. The handles are an integral part of the respective members associated therewith. The panel's side edges taper inwardly toward one another in a direction toward the bottom edge thereof and the pouch side edges have a corresponding taper. The upper surface of the panel has a matt non-slip surface as does also the flexible cover sheet.

Abstract: A flexible spine binder with an open pocket extending the length of the spine and a stiff elongate member insertable into such pocket transforming the flexible spine into a stiff spine and also providing means for labelling the binder. The binder is made of film vinyl, polypropylene or the like.

Abstract: A book cover assembly has a book, a cover and a retainer securing the book to the cover. Pivot members associated with either mounting means for securing the cover to a fixed structure or the cover are biased to pivot to a position associated with the cover in a closed configuration by biasing means associated with the other of said mounting means and cover. The biasing means engage the pivot members under urging from the book as it falls from an open upper position.The mounting assembly is disposed at 45.degree. to the spine of the book cover assembly and is hinged at 45.degree. to a mounting plate so that the book can be moved from a preferred stored orientation which is side face-out to a conventional open orientation with the spine at 90.degree. to its original position. A variation for accommodating a pair of books in tandem is also described in which the books will locate in a preferred orientation.
