The present application relates to the technical field of privacy computing, and specifically provides a distributed multi-party asynchronous isolated secure retrieval method and device, wherein a shared network is formed by a data retrieval initiator and a data owner using a front-end machine cluster node, retrieval business is completed based on a front-end machine TEE (Trusted Execution Environment) and a hidden query method; a permission control unit is configured on remote authentication permission control of the TEE, permission monitoring at an instruction level is realized, and through sensitive data desensitization, open data and ciphertext query data confusion, query initiator anonymization and query condition fuzzification, query intention request collection, it is ensured that the entire life cycle of data query and statistical operation is carried out in a trusted isolated environment, and the security and privacy protection of data are strengthened. Compared with the prior art, the present application effectively prevents malicious operation and illegal access, thereby ensuring the security and privacy protection of data.

The present invention provides a method, apparatus and related equipment for uploading terminal data to a blockchain, which relates to the field of communication technologies. The method for uploading terminal data to a blockchain includes: receiving a request for uploading service data, where the request for uploading service data is a request sent by a terminal to the SIM card in response to receiving a first operation; and in response to the request for uploading service data, sending a first command to the terminal based on a data transmission protocol, where the first command is used to establish a communication connection relationship among the SIM card, the terminal and the blockchain platform. By using the SIM card to send a first command to the terminal to establish the communication connection relationship among the terminal, the SIM card and the blockchain platform, the embodiments of the present invention avoid directly establishing a communication connection relationship between the terminal device and the blockchain platform, thereby reducing the risk of leakage of terminal communication information.
