Abstract: Some embodiments disclose a method and apparatus for processing data, a computer device and a storage medium. A method can include: acquiring, by a cloud storage system, a series of slices obtained by dividing a to-be-stored file; encrypting, by the cloud storage system, each slice by using a different data key; and storing, by the cloud storage system, an encrypted data ciphertext.

Abstract: The objective of the present invention is to provide a method, apparatus, system, computing device and computer-readable medium for data migration between cloud storage systems. Here, a user equipment generates, according to a list of to-be-migrated files, descriptive information of each file in the list; and transmits one or more data migration requests to available server(s), respectively, such that the corresponding server performs data migration between different cloud storage systems, wherein each data migration request includes indication information of a source end and a destination end of the data migration and descriptive information of one or more to-be-migrated files. The present invention may satisfy various performance requirements on performance, flexibility, scalability, automation, data verify and framework universality, etc.

Abstract: A method and an apparatus for processing data are provided. The method includes: determining, in response to receiving an access request sent by a client and a target path in a complete binary tree, a time interval between the access request and a last access request as a second time interval, a value of a non-leaf node of the complete binary tree being related to a time interval of latest two access requests received by a metadata server, a leaf node being used to represent a virtual node in a distributed system; determining a change amount of a value of a node in the complete binary tree according to the target path and the second time interval; querying an access result according to the access request, and sending the access result to the client; and sending the change amount to a management server end.

Abstract: Embodiments of the present disclosure relate to a method and an apparatus for processing data. The method can include: determining, in response to receiving an access request, a time interval between the access request and a last access request as a first time interval; acquiring a preset complete binary tree from a management server end, a value of a non-leaf node of the complete binary tree being related to a time interval of latest two access requests received by a metadata server, a leaf node being used to represent a virtual node in a distributed system, and the virtual node corresponding to the metadata server; selecting a target path from the complete binary tree according to the first time interval; and sending the access request and the target path to a metadata server corresponding to a leaf node of the target path.

Abstract: An authority management method and device in a distributed environment, and a server are provided. The method includes: obtaining usage information of a user when the user uses an object storage product, the usage information including the user's behavior, status and feature; determining a matching degree between the usage information of the user and usage information predicted by a portrait model of the user; and applying a preset early warning mechanism to the user's access authorities according to the matching degree.
