An approach is disclosed that selects a current processing element from a set of processing elements included in a software pipeline. A selected input data to the current processing element was an output data from a previously executed processing element. The input data is verified by computing a current fingerprint of the selected input data and comparing the computed fingerprint to an expected fingerprint. The expected fingerprint was previously computed after the output data was generated by the previously executed processing element. In response to the comparing revealing that the current fingerprint fails to match the expected fingerprint, a verification error is indicated to a user of the process.
