Abstract: A blockchain-based user privacy data providing method and apparatus is provided. The method includes receiving a data consumption request from a data consumer, where the data consumption request requests user privacy data of a target user, the user privacy data includes personal data that is pre-encrypted and uploaded to a trusted execution environment (TEE), and the TEE is constructed in a blockchain node; performing predetermined verification on the data consumption request in the TEE based on request body data corresponding to the data consumption request using a smart contract deployed in the blockchain to obtain a corresponding predetermined verification result; if the predetermined verification result satisfies a verification success condition, obtaining target privacy data for the data consumption request, and sending the encrypted target privacy data to the data consumer, where the target privacy data is obtained in the TEE based on the user privacy data stored in the blockchain.

Abstract: An online game anti-cheating method is provided. The method includes sending cheating program characteristics to a client and receiving characteristics matching with cheating program characteristics reported by the client. The method also includes matching the reported characteristics with characteristics in at least one stored characteristic list and obtaining a determination result based on a matching result. Further, the method includes returning the determination result to the client and to cause the client to react to the determination result.

Abstract: Methods and systems for processing report information are provided herein. An exemplary method can be implemented by a computer system. The method can include receiving a reporting from an informer. The informer can submit report information including at least a user identification (ID) of a reported person. It can be determined whether the reporting is valid, according to the user ID of the reported person. When the reporting is valid, the reported person can be punished according to a preset punishment strategy. First feedback information indicating a valid reporting can be sent to the informer, and second feedback information indicating reasons for punishing can be sent to the reported person. When the reporting is invalid, third feedback information indicating an invalid reporting can be sent to the informer.
