Abstract
A system for detecting leakage of email addresses generates an alias email address that will be used by a user to register with a web service. The alias email address is an alias for a primary email address of the user, and is paired with the web service. The web service is included in a whitelist upon confirmation from the web service that the alias email address has been registered with the web service. Emails that are addressed to the alias email address and from the web service are forwarded to the primary email address. Emails that are addressed to the alias email address but is not from the web service are detected to be suspicious.
