Abstract: Systems and methods of rotating content license management for multiple terminals associated with the same content service subscription user account are disclosed. An ephemeral master device (EMD) is selected from a domain of client devices associated with the same user account. The content service generates an Ephemeral Personal Credential (EPC) associated with the user account, which is temporary and is updated periodically or randomly. The EMD role rotates among the devices in the domain periodically or randomly. The updated EPC is sent to the current EMD. A client device can access content via the user account by providing 1) the account credentials and 2) a valid EPC. Account credentials may be shared with the client device. The EPC is shared with the client device when the client device moves within a particular range of the EMD (or another device in the domain which has the EPC) to synchronize the EPC.

Abstract: Systems and methods are described for content distribution at a distributor. A functionally encrypted content request comprising a user identifier and a content identifier is received. The functionally encrypted content request is sent to a content provider. A content reply comprising the functionally encrypted content request and encrypted content corresponding to the content identifier is received. The content reply is decrypted using a functional user identifier decryption key to resolve the user identifier. A further content reply corresponding to the content reply is sent to a user node corresponding to the user identifier.

Abstract: A privacy-preserving process for communicating over a decentralized peer-to-peer network is described in which a user device receives a digitally signed temporary user ID from an identification service, and initiates a transaction with an online content provider using the digitally signed temporary user ID and cryptographically encrypted user payment information. The user device receives data from the content distributor in response to the content distributor receiving a first indication of payment for the transaction from a payment service. In this method, the first indication of payment for the transaction to the content distributor was to have been transmitted by the payment service device in response to: the payment service device receiving the temporary user ID and linking the temporary user ID to the user information; and the payment service receiving a second indication of payment based on the user information.

Abstract: Systems and methods are described for content license key distribution where the privacy of a user is preserved. A content request from a user is received by a content distributor, the content request including a content identifier and a user identifier. On verification that the request from the user is valid, the content distributor acquires a content license from a content supplier, verifies it, and sends the content license to the user such that the user may consume the content. The user's identity is kept private by the use of signed keys, one-time identifiers, and the use of encryption. In addition, a one-time identifier of the user may be validated by an attestation service.

Abstract: A problem with online transactions is that a customer may unwillingly be profiled by a corporate entity. To hinder such profiling, a customer may occasionally generate a public/private key pair, and present the public key to a digital token service for use as a pseudonym included in tokens issued to the customer. A subsequent assignment of the digital token to a corporate entity can then be performed by adding the public key of the corporate entity to the token, and signing the combination with the private key which pairs with the pseudonymous public key in the token. A return transaction from the corporate entity to the customer can then add the pseudonymous public key to a return digital token and sign the combination with the corporate entity's private key. Routing the digital token to the customer may be achieved by replying directly to the anonymous inbound token.

Abstract: A peer-to-peer content provision network is disclosed which implements a privacy-preserving payment mechanism for rewarding actors in the network (for example, a content supplier, a content distributor and storage-contributing peers). To reward some or all of those actors, a user device obtains, from a token service, anonymous digital payment tokens which include an ephemeral public key. Payment is achieved by adding an assignment layer to the token which involves combining a payee ephemeral public key with the token, and applying a digital signature to the combination using the ephemeral private key corresponding to the ephemeral public key in the token. Subsequent assignments can be made by the payee by adding a further assignment layer to the token using a payee ephemeral private key which pairs with the payee ephemeral public key in the received token. A payment service can divide a payment from the user between actors in the network.
