Choreography, orchestration and dynamic invocation allow new web services to be composed from existing ones. However, these compositions create service interdependencies that can be misused for financial fraud and other illegal purposes. When a misuse is reported, investigators have to navigate through collections of logs to recreate the invocation scenario in order to evaluate the misuse claims. We propose the creation of forensic web services that can securely maintain transaction records between web services. An independent entity could use the stored records to reproduce the complete transaction history when investigating a misuse claim.
Gunestas, et al. REF have introduced "forensic web services" that can securely maintain transaction records between web services.
