Abstract: Methods and systems implement a virtual copy operation which improves support of preemptive garbage collection policies at a distributed file system. A garbage collection process preemptively performs copying upon data in a log-structured file system. So that thread-blocking write operations are not distributed across nodes of a distributed file system node cluster, and thus avoid degradation of computational performance, a virtual copy operation is provided which, based on master node metadata, locates each chunk node storing blocks to be virtual copied and calls a remap API of a logical address mapper provided by a local file system of the chunk node. The logical address mapper of each chunk node performs remaps of disk addresses from source logical block addresses to destination block addresses, without relocating data from one disk address to another. The results of these remaps may be stored as metadata at the master node, replacing previously mapped metadata.

Abstract: The present disclosure provides a method and an apparatus for user verification. A terminal device recognizes a sequence of click operations made by the user according to a maneuver prompted on a terminal device. The sequence of click operations carries operation information from which a click pattern characteristic, such as a characteristic code, can be determined. Upon receiving the determined click pattern characteristic, a server verifies the user input by matching the click pattern characteristic with a verification code set or stored by the server. The click pattern characteristic may be based on recognizing clicking or tapping operations performed by the user at a specified time and/or in a designated area. The method enables user verification on devices that lowers the rate of errors in the user input of verification codes.

Abstract: The present disclosure discloses a method and an apparatus of account login to solve the problem of low efficiency of account login in existing technologies. A client of the method captures an image of a first credential of a user, recognizes user information of the user that is included in the captured image, includes the recognized user information into a login request, and sends the login request to a server for logging into an account that corresponds to the user information. Through this method, a user does not need to input his/her username when using a client for account login, but perform the account login by directly capturing an image of a first credential using an image capturing device of the client, thus effectively improving the efficiency of account login.
