【摘要】 NOVELTY - The method involves searching (501) the data abstract index of the credit information of the target user in the credit information blockchain by the first credit mechanism node, when the first credit mechanism node needs to obtain the credit information of the target user. The information of the second credit mechanism node is obtained (502) through the data digest index by the first credit mechanism node, when searching the data abstract index of the credit information of the target user. The query request of the credit data of the target user is sent (503) to the second credit mechanism node by the first credit mechanism node based on the information of the second credit mechanism node. The private key signature of the second credit node is verified (504) based on the pre-obtained public key of the second credit mechanism node by the first credit mechanism node. USE - Method for managing financial credit information applied to internet credit system based on blockchain. ADVANTAGE - The method not leaks the self-credit data through credit mechanism node, queries the credit data of the self-mechanism node, reaches the mutual benefit of data sharing, and avoids the privacy data leakage of the user. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a device for managing financial credit information applied to internet credit system based on blockchain; (2) an electronic device for managing financial credit information applied to internet credit system based on blockchain; and (3) a computer readable storage medium storing program for managing financial credit information applied to internet credit system based on blockchain. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating a method for managing financial credit information applied to internet credit system based on blockchain. (Drawing includes non-English language text) Step for searching the data abstract index of the credit information of the target user in the credit information blockchain by the first credit mechanism node, when the first credit mechanism node needs to obtain the credit information of the target user (501) Step for obtaining the information of the second credit mechanism node through the data digest index by the first credit mechanism node, when searching the data abstract index of the credit information of the target user (502) Step for sending the query request of the credit data of the target user to the second credit mechanism node by the first credit mechanism node based on the information of the second credit mechanism node (503) Step for verifying the private key signature of the second credit node based on the pre-obtained public key of the second credit mechanism node by the first credit mechanism node (504)
