The invention provides a system for implementing security sharing of virtual articles among application programs. The system comprises a data storage module, a shared article registering module, a verifying module, an executing module and an application program request processing module. With the adoption of the system, a developer can manage the sharing process through authorizing a shared interface and changing an interface, and application programs which are not authorized are prevented from illegally accessing the shared interface, so that the security of a virtual article system is protected.
