Abstract: Methods, systems, and products are disclosed in which generating evidence of web services transactions are provided generally by receiving in an ultimate recipient web service from an initial sender a request, the request containing a proof of message origin (‘PMO’). The PMO contains an element addressed to the ultimate recipient web service and the element bears a first signature, the first signature having a value. Embodiments also include authenticating the identity of the initial sender; creating a proof of message receipt (‘PMR’) including signing the value of the first signature; sending the PMR to the initial sender, receiving, by the initial sender, the PMR; and saving, by the initial sender, the PMR.

Abstract: A web services framework consists of a modular, extensible stack of XML specifications and standards targeting the emerging infrastructure in which distributed, heterogeneous applications are exposed by different organizations as services on the Internet. These services have their capabilities described and published in a machine readable format.
