Access authority control method and device

The invention discloses an access authority control method and device, and relates to the technical field of computers. The method is applied to a service system, and the service system comprises a plurality of subsystems. A specific embodiment of the method comprises the following steps: receiving an access request, wherein the access request indicates a first account; verifying whether the first account has the login permission of the current subsystem, and if so, determining a first role corresponding to the first account and a first access permission corresponding to the first role according to an association relation table; and according to the first access permission, determining system resources which can be accessed by the first account, and allowing the first account to operate the determined system resources according to the first access permission. According to the embodiment of the invention, centralized access permission control of a plurality of subsystems in the service system is realized, effi
