Title : Using Cross-Media Relations to Reduce False Positives during SPIT Filtering
Author(s) : K. Ono, H. Schulzrinne
Filename : draft-ono-cross-media-relations-00.txt

Some legitimate calls are from persons or organizations connecting
the callee with weak social ties, such as a restaurant the callee booked a table on-line. These legitimate calls are often mistakenly
labeled as unsolicited calls at a filtering system which uses the
contact list of the callee. To reduce these false positives during
SPIT filtering, we propose two approaches to label incoming calls
using cross-media relations from earlier communications. One
approach is that a potential caller offers the callee his contact
address(es) which might be used in future calls. Another is that a
callee provides a potential caller with weakly secret information.
In order to be identified as someone the callee contacted through
other means previously, the caller should convey the information in
future calls.
