The invention relates to the technical field of computers, and discloses a
user role and authority management method,
system and device and a storage medium, and the method comprises the steps: accessing multi-
source data, carrying out the preprocessing, and constructing a context snapshot; receiving request information, and analyzing a user intention; based on the context snapshot and the request context, reasoning, dynamic role affiliation judgment, authority demand assessment,
risk assessment and decision suggestion output are carried out through a
large model; the decision suggestion is converted into an
executable technical instruction so as to dynamically adjust the user permission, the technical instruction comprises application program interface calling, configuration changing or strategy rule updating, and user permission adjusting comprises role distribution and permission granting or
revocation; and in response to an execution result of the received technical instruction, a user behavior and an audit log, analyzing a decision effect, identifying a decision deviation, and optimizing the
large model through a feedback learning mechanism. According to the invention, the flexibility, safety and efficiency of authority management can be improved.
