Business parameter comparison method, device and system and storage medium

The invention discloses a business parameter comparison method, device and system and a storage medium, and belongs to the field of big data processing. The method comprises the steps of obtaining a first interaction character string and a first result character string based on a first binary character string obtained through conversion of a first service parameter of first equipment, a randomly generated first label character string and an agreed initial random character string; sending the first interaction character string to a second device, so that the second device obtains a second result character string based on a second binary character string obtained by conversion of a second service parameter of the second device, the initial random character string, a part of randomly generated second label character string and the first interaction character string; and interacting with the second device based on the first result character string and the second result character string, and performing fragmentati
