Abstract
Disclosed herein are systems, methods, and media for processing and updating risk assessment information of a user. One of the methods here comprise: obtaining risk assessment information and digital identity of the user; creating a first verifiable claim based on the digital identity and the risk assessment information by using a first blockchain, revoking a second verifiable claim of original risk assessment information corresponding to the digital identity by using the first blockchain; uploading the first verifiable claim to a second blockchain; obtaining a storage credential of the first verifiable claim in the second blockchain, wherein the second blockchain is connected to a service processing platform; generating a risk assessment card corresponding to the user based on the storage credential and the first verifiable claim; and allowing the service processing platform to obtain the risk assessment information of the user from the second blockchain by using the risk assessment card.
