Abstract
A system (50, 150) for assisting a user (14) to determine whether an email (18) comes from a purported originator (16). A computerized system having a display unit is provided. Logic (54) in the computerized system determines whether the email (18) includes an authenticity mark (52) including an originator identifier (102) and encrypted data (104). Logic (54) in the computerized system then decrypts the encrypted data (104) into decrypted data (108-14), based on the originator identifier (102). Logic (54) in the computerized system then presents to the user (14), on the display, whether the email (18) includes the authenticity mark (52), whether the encrypted data (104) decrypts successfully, and information based on the authenticity mark (52) and the decrypted data (108-14).
