Comparing XML signatures

Hi,
While working through Web services security, we  came across XML signatures 
for data integrity. We have been reading and implementing it in the .Net 
framework. We have been working with a design for web services security for 
cross domain authentication and data confidentiality, in which we think that 
an XML signature can be used for two other purposes too. One, to provide an 
identity to the clients from a specific domain. Two, to authenticate the 
request comming into the web service. As we are still doubtful about the 
robustness of this architecture, we would like to know whether a service can 
compare two signatures in order to ensure the authenticity and whether XML 
signatures can really be used for this purpose or if not what would be the 
alternative.
Thanks in advance for any help.

Best Regards,
Abdul.
