An example operation may include one or more of connecting, by a recipient node, to a blockchain network configured to store links to digital assets of an owner, selecting, by the recipient node, an asset from a ledger of the owner, executing, by the recipient node, a smart contract to determine a time frame of the asset use, executing, by the recipient node, a smart contract to download the asset to the recipient node, checking, by the recipient node, if the asset is downloaded successfully, and in response to the successful download of the asset, executing, by the recipient node, a smart contract to log an asset transfer transaction onto the blockchain.

A computer system receives, by a messaging application, information identifying a first shared content item as shared content. The first shared content item is of a first type. In response to receiving the information identifying the first shared content item as shared content and in accordance with a determination that a first application of the plurality of applications can open content of the first type, in accordance with a determination that providing the information identifying the first shared content item as shared content to the first application has been authorized, computer system device automatically makes the first shared content item available within the first application, and in accordance with a determination that providing information identifying the first shared content item as shared content to the first application has not been authorized, the computer system does not make the first shared content item automatically available within the first application.

Permissions can be delegated to enable access to resources associated with one or more different accounts, which might be associated with one or more different entities. Accordingly, approaches for delegating security rights and privileges for services and resources in an electronic and/or multi-tenant environment are provided. In particular, various embodiments provide approaches for dynamically determining and authorizing delegation of permissions to perform actions in, on, or against one or more secured accounts, where those accounts may be associated with a number of different entities and/or resource providers.

Embodiments of the present disclosure relate to digital rights management. A method for managing rights transfer of using digital content from a first device (120) to a second device (130) is proposed, comprising generating at an authentication device (110) a first authentication dataset C by encrypting a first verification code R1 using at least one public key for at least one device blacklisted by the authentication device (110). The first authentication dataset C and a second verification code R2 are provided from the authentication device 110 to the first device (120) and a response message M is returned from the second device (130) to the authentication device (110). The method also comprises verifying validity of the second device (130) at the authentication device (110) based on the received response message M. In accordance with embodiments of the present disclosure, the DRM protected digital content can be shared with high security, while the recipient is kept anonymous to the DRM server.

The present disclosure relates to systems, methods, and computer-readable media for providing digital content for an application to users. For example, systems described herein can provide a license for the digital content during a rental time. Systems disclosed herein may additionally track a duration of use of an application and compare the tracked use against an amount of rental time purchased (e.g., rented) by a user. The systems described herein may further extend a license or terminate the license based on a determination of whether the amount of use exceeds a rental time. Features and functionality described herein provide a flexible and efficient mechanism that enables users having a variety of content-consuming preferences to receive affordable content while ensuring that use of an application is efficiently and accurately tracked.

A proprietor terminal stores state data in which an identifier of a contract executed in a blockchain system, a hash value of control target file data that specifies content data managed by the contract, and an identifier of a proprietor and an identifier of a user of the content data in the file management system are associated with one another, and includes a route object generation unit that generates reference destination data having the identifier of the contract and generates route object data having the reference destination data and a link name and the hash value of the control target file data.

While displaying a view of a first application of a plurality of applications stored in the memory, an electronic device displays a representation of a first shared content item that upon selection is invoked by the first application, and a selectable attribution affordance that provides a link to a location in a second application where information identifying the first shared content item was initially shared.

A terminal device for sharing a display of a content with another terminal device, includes a unit configured to determine a role of an own-device, from between a first or second role, the first role for applying an operation performed on the content to the content of the other terminal device, and the second role for performing a part of the operation of the first role; a unit configured to receive a part of the operation of first role, and apply the operation to the content included in the other terminal device, when the own-device has the second role; and a unit configured to display the content included in the own-device upon applying the operation performed at the terminal device having the first role, based on information from the first role, when the own-device does not have the first role.

A system and method for media content management include creating, via a digital vault, a container file comprising media content submitted by a first user and content metadata; verifying, via the digital vault, a completeness of the content metadata associated with the media content in the container file; classifying, via the digital vault, the container file based on the completeness of the media content; capturing, via the digital vault, event metadata when a second user gains access to the container file, the event metadata comprising at least one of identification of the second user, an activation timestamp, a duration of access, portions of the container file accessed, and changes to the container file; and enabling a private communication channel between parties affiliated with the media content to permit messaging among the parties affiliated with the media content via the private communication channel.

Permissions can be delegated to enable access to resources associated with one or more different accounts, which might be associated with one or more different entities. Accordingly, approaches for delegating security rights and privileges for services and resources in an electronic and/or multi-tenant environment are provided. In particular, various embodiments provide approaches for dynamically determining and authorizing delegation of permissions to perform actions in, on, or against one or more secured accounts, where those accounts may be associated with a number of different entities and/or resource providers.
