1. A computerized method performed by one or more processors, the method comprising: receiving, at a receiving entity via a cloud-based integration system, a business-to-business (B2B) communication from a sending entity, wherein the B2B communication includes a set of data associated with at least one business transaction, where the received B2B communication is in a target format, and wherein the cloud-based integration system transforms an original B2B communication in a source format sent from the sending entity into the target format of the B2B communication received at the receiving entity; receiving, at the receiving entity, a digitally-signed sender fingerprint of critical fields, wherein the critical fields are extracted from the set of data associated with the at least one business transaction in the source format of the original B2B communication; verifying, at the receiving entity, that the received sender fingerprint was signed by the sending entity; generating, at the receiving entity, a receiver fingerprint of the received B2B communication in the target format based on the critical fields extracted from the received B2B communication based on a pre-defined algorithm; and comparing the verified sender fingerprint and the generated receiver fingerprint to determine that the sender fingerprint and the receiver fingerprint are identical.
