Abstract: Electronic communication is susceptible to SPAM, phishing attacks, and other unwanted communications because of a recipient's limited control over communication transmitted by a sender. Functionality can be implemented to employ a multi-level approach to establishing trust between a sender and a recipient prior to transmitting any communication to prevent unwanted content from being transmitted to a recipient. Initial levels of trust may be established by requiring the sender to provide trust establishment information about the recipient. Based on the validity and percent accuracy of the provided trust establishment information, the communication may be discarded or transmitted to the recipient. A final level of trust depends on the approval of a trust validation request sent to the recipient on behalf of the sender.
