Abstract: A method and an apparatus for controlling a data access right are disclosed. The method includes: receiving, by a first proxy node, a first request message from a request node, where the first request message includes an identity of the request node and an identifier of to-be-accessed data; determining a first encrypted ciphertext on a blockchain based on the identifier; determining, based on the identity, whether the request node has a right to read the first encrypted ciphertext; and if yes, initiating a right verification request for the request node to at least one second proxy node, and determining, based on a feedback result of the at least one second proxy node, provisioning of the first encrypted ciphertext. A proxy node is added to the blockchain network, so that a data source can freely grant or revoke the right of the request node without modifying a ciphertext, ensuring information security.

Abstract: The present disclosure relates to the field of communications technologies, and provides a multi-stream transmission method and device in an SDN network. A server obtains network status information of a network by using an SDN controller; determines, according to the network status information and a data sending rate requirement of a client, a quantity of sub-streams and a sub-stream transmission path that are required by a multi-stream connection, and allocates corresponding sub-stream identification information to each sub-stream; and sends the determined sub-stream transmission path and the corresponding sub-stream identification information to the SDN controller. According to the foregoing solution, the server completes multi-stream connection path planning according to the network status information, and the SDN controller only provides the network status information for the server without performing the multi-stream connection path planning, so that calculation load of the SDN controller is reduced.

Abstract: In an embodiment a method for panoramic video playback is disclosed. The method includes determining, by a client, that a new time point to play a video in a panoramic video is indicated, matching, by the client, the new time point and a time range of each of at least one interest point included in the panoramic video and before the time point and the time range of each of at least one interest point in the panoramic video is matched, obtaining, by the client from a server, description information of each of the at least one interest point in the panoramic video, wherein the description information includes the time range of the interest point and an area of the interest point. When the client finds that the new time point falls within a time range of an interest point the client determines a user's field of view in which an area of the matched interest point is viewable.

Abstract: An information management method includes: receiving an information import request sent by a first agent node, where the information import request includes a first identifier of a user; obtaining a second identifier of the user based on the information import request, and obtaining to-be-imported personal information corresponding to the second identifier of the user; and sending metadata of the user to a block chain node, to store the metadata of the user into the block chain system. In this way, personal information of the user is registered in the block chain system, so that security of the personal information can be effectively ensured, and the user can perform management of and provide external authorized access to the personal information of the user in a unified manner.

Abstract: In various embodiments, a client device can obtain user field of view information and recommended field of view information of a panoramic video. The client can then determine, based on the user field of view information and the recommended field of view information, that a field of view range corresponding to a recommended field of view is not within a range of a user field of view. The client can display an image corresponding to the user field of view and an image within the recommended field of view. An image corresponding to a recommended field of view can be prompted and presented, so that the user independently determines whether to switch a field of view.
