  • Patent number: 11949681
    Abstract: Methods and systems are provided for improving user authentication and access control by a network file system service in a multi-tenant public cloud environment by receiving a request for a connection to a file system from a file system client (client), sending an identification request for identification authentication of the client to a control system, receiving a response from the control system, establishing the connection to the file system upon determining that the connection to the file system is allowed based on cloud tenant information associated with the client, receiving an attempt to access the file system from the client by a sub-user, authenticating the sub-user based on the cloud tenant information, issuing a security token including a globally unique sub-user identifier of the sub-user, and using the security token to determine access rights of the sub-user to the file system for a subsequent request.

  • Publication number: 20240104304
    Abstract: This specification provides a method and an apparatus for estimating a word segment frequency in differential privacy protection data, and an electronic device. According to the method, each piece of word segment information that is reported by a terminal device and that is subject to local differential privacy processing is obtained; N groups of word segment information are obtained through division, so each piece of word segment information of the same group corresponds to the same target quantity; each group of estimated data that is corresponding to each group of word segment information and that represents unbiased word segment frequency estimation is determined; and each layer of nodes of a prefix tree used to record a word segment frequency is generated layer by layer based on each group of estimated data.
