Individual resource is independent of each other in the dispersive storage system which brings about difficulty to managing resources and inconvenience to users to access resources, as well as reduction of availability of shared information. Considering the problem as mentioned above this article proposes integrating disperse through establishing storage resources based on the mode of “disperse storage, unified allocation and centralized user management” through establishing an UAMS(User Authentication and Management System) and managing users with virtual account. In this mode, UAMS acts as intermediate to separate users from resources. This provides convenience to users for accessing many dispersive resources and avoids repetitive management to users in each storage system. It can realize uniform user management of dispersive storage system on the precondition of preserving intrinsic management model. It’s convenient for users to access information. The UAMS can highly increase the usability of network storage system and the information resource sharing. The use of users authentication improves the security of storage system
