Abstract: In embodiments of the present disclosure, a method for identity authentication is provided, which includes determining a confidence of an authentication node based on historical behavior, consensus, contribution, and security of the authentication node. The method further includes: receiving, by the authentication node, encrypted data of a user in response to the authentication node being a trusted node, where the authentication node is a node in a decentralized network and is connected with the Internet through a communication protocol to receive and authenticate encrypted data from the Internet, and the encrypted data includes personal information associated with user information and a signature issued by a publisher; decrypting the encrypted data; and determining an identity of the user based on authentication of the decrypted data. By using the method implemented in the present disclosure, the complexity of decentralized implementation is reduced, the user experience is improved, and users multiple sign-on options.

Abstract: Embodiments of the present disclosure relate to a method, an electronic device, and a computer program product for data storage. The method includes determining, based on attribute information of each of a set of nodes in a distributed storage system, a hash value of each of the set of nodes; determining a node identifier of each of the set of nodes based on geographic location information of each of the set of nodes and the hash value, with the node identifier being used to indicate a logical location of a node in the distributed storage system; and determining, in response to a processing request from a first node in the set of nodes for first data, a target node in the set of nodes based on the node identifier of each of the set of nodes. The target node is used to process the processing request for the first data.

Abstract: Embodiments of the present disclosure relate to a caching method, device, and computer program product for an edge server. The method includes acquiring a historical distribution of a set of variables associated with a network environment of the edge server, and generating one or more time series of the set of variables based on the historical distribution. The method further includes determining a caching strategy associated with the edge server based on the one or more time series of the set of variables. With the solution of the present disclosure, in an edge computing scenario, unnecessary overhead caused by ineffective caching can be reduced while ensuring smooth user experience.

Abstract: Embodiments of the present disclosure include a method, an electronic device, and a computer program product for searching for data. The method includes: determining, in response to receiving at a requesting node a search request for target data, a data identifier of the target data; and determining whether the data identifier of the target data is a local data identifier or a global data identifier. The method further includes: searching for the target data using a local distributed hash table in response to determining that the data identifier is the local data identifier; and searching for the target data using a global distributed hash table in response to determining that the data identifier is the global data identifier. By using this method, it is possible to enable quick lookup of various types of data among nodes in a distributed system in a low-latency, flexible, and efficient manner.

Abstract: The present disclosure relates to a method, a server, and a computer program product for identity authentication. The method includes searching, in response to receiving an identity authentication request from a user at an edge server, an identity authentication database of the edge server for identity authentication information associated with the user. The method further includes sending, in response to the identity authentication information associated with the user not being found in the identity authentication database, the identity authentication request to a cloud server, the cloud server including an agent for interfacing with a plurality of identity authentication providers. In addition, the method further includes receiving the identity authentication information associated with the user from the cloud server, storing the identity authentication information to the identity authentication database, and using the identity authentication information to authenticate the user.

Abstract: Embodiments of the present disclosure relate to a method, an electronic device, and a computer program product for cross-regional data searching. The method includes acquiring a data identifier of target data in response to receiving a searching request for the target data at a first node. The method includes determining, based on the data identifier, a second node storing metadata of the target data, wherein both the first node and the second node are located in a first region, and the metadata includes the data identifier. The method further includes determining, based on the metadata, a third node storing the target data, wherein the third node is located in a second region different from the first region.
