Abstract: A method and system for controlling the use of a temporary password is provided, and the method includes the steps: generating by a random code generator end a preset number of temporary passwords after successful matching between the random code generator end and the random code use end; sending by the random code generator end at least one temporary password among the preset number of temporary passwords to the random code use end for storage therein to form a preset temporary password; and receiving a current temporary password, comparing the current temporary password with each of the pre-stored temporary passwords, and indicating successful verification if the current temporary password is the same as one of the pre-stored temporary passwords. The method can generate multiple temporary passwords at once, and control and manage the use of temporary passwords by adding function codes to the temporary passwords.

Abstract: A method and software is described for recreating on a target datastore a set of hierarchical files that are present on a source datastore. A content identifier (ID) is maintained for each component of the set of hierarchical files. The content ID of a component is updated when its contents are modified. The child component is copied from the source datastore to the target datastore. The content ID corresponding to the parent component on the source datastore is compared with content IDs corresponding to files present on the target datastore. When a matching content ID is discovered, it infers a copy of the parent component. The matching file on the target datastore is associated with the copied child component so that the matching file becomes a new parent component to the copied child component, thereby recreating the set of hierarchical files on the target.
