A credit report transfer method based on blockchain and intel SGX

Abstract

The invention discloses a credit investigation report circulation method based on a block chain and Intel SGX. The method comprises a credit investigation authorization stage, a credit investigation providing stage and a credit investigation query stage. In the credit investigation authorization stage, a credit investigation report format is customized by a personal user, and the specific authorization information is set; in the credit investigation providing stage, a credit investigation mechanism generates a credit investigation report according to a report format defined by a personal userand authorization information; and the credit investigation stage is used for inquiring and auditing a credit investigation report provided by a credit investigation mechanism by a financial institution. The report formats, the authorization information, the credit reports and the report query records involved in the flow process are encrypted through SGX and stored on the block chain. By combining the block chain and Intel SGX, the non-tampering, traceability and privacy protection of data in the credit report transfer process are realized, and the problems that a paper report is easy to tamper and forge, the user privacy attention is low, and a management and control credit report cannot be abused due to a traditional transfer method are solved.
