User permission dynamic allocation method and device and storage medium

The invention discloses a user permission dynamic allocation method and device and a storage medium, and the method comprises the steps: fusing an identity information vector and a permission vector through a fusion model, and generating a current state vector of a user; mapping the user task to form a user task vector; calculating a user permission vector according to the user current state vector and the user task vector, so that mutual information between the user task vector and the user permission vector is maximum, and mutual information between the user permission vector and the user state vector is minimum; and obtaining a current task permission list according to the user permission vector, and adjusting the user permission according to the current task permission list. The method can ensure that a system user always operates in a minimum authorization state, and effectively prevents security incidents caused by excessive authorization of the user or accumulation of user permissions. 本发明公开了一种用户权限动态分配
