The invention provides an information matching method and a device, the methods include: a match initiating side sends information matching request to a match initaiating recipient, the matching recipient verifies the information in the information matching request, if the verification passes, a first response to the information matching request is constituted, sending to the matching initiator, verifying the information in the first response after the matching initiator receives the first response, if the verification passes, sending a second response to the matching receiver, obtaining a first calculation result according to the first commitment and the second commitment by the matching initiator, obtaining a second calculation result according to the first commitment and the second commitment by the matching receiver; after receiving the second response, the matching receiver compares the first calculation result with the second calculation result. If the comparison result is equal,the matching is successful. If the comparison result is not equal, the matching fails. The invention solves the technical problem that the accuracy of the matching result is not high in the prior art.
