Abstract

The invention discloses an access control method and device, equipment, a medium and a product. Relates to the technical field of computers and block chains, can be applied to the field of financial science and technology, and comprises the following steps: if it is detected that a target user sends an access request to a target system in a request system, performing identity verification on the target user according to a subject-object attribute contract in a block chain; under the condition that the identity verification of the target user is passed, determining a target role to which the target user belongs, and determining a target permission corresponding to the target user according to the target role; and determining a current credit value of the target user, and determining an access control strategy for the target user according to the access request, the current credit value and the target permission so as to indicate the target system to provide resources within the permission range for the request system. According to the technical scheme provided by the invention, safe and effective access control among different systems can be realized by utilizing the block chain technology and combining the credit condition of the user.
