The invention provides an information processing method and device. After a data access request is obtained, whether identity information carried in the data access request is qualified is verified atfirst, after it is confirmed that the identity information is qualified, voting results of multiple heterogeneous executive bodies on an independent processing result of the same input data, and corresponding processing logs of the multiple heterogeneous executive bodies can be obtained, thereby avoiding illegal operations of illegal users, and furthermore, in the embodiment, whether the multipleheterogeneous executive bodies contain an abnormal heterogeneous executive body is analyzed by combining the voting results and the multiple processing logs, and the abnormal heterogeneous executivebody is replaced in time, thereby solving the technical problem in the traditional scheme that, the abnormal heterogeneous executive body is only determined according the voting results, such that coordinated attack vulnerability caused by a system configuration error cannot be solved, and ensuring the safe and stable operation of a computer device.
