Abstract: A system and method for in-store printing of coupons selected from a remote computing device, such as a smart phone, or a home computer. Users register their mobile phone numbers into the system's web site; once coupons are selected, an access code is sent by SMS (“text message”) to the user's registered mobile phone. The user then goes to a selected store to print the coupons in a dispensing kiosk, using his/her mobile phone number and the access code that was sent to it. Printed coupons expire the same date they are printed, and should be redeemed the same day in the store they are printed. Each coupon will have printed a GS1 databar code containing information that can be used for market analysis purposes.

Abstract: A system and method for authenticating email messages from trusted sources. A trusted sender (TS) registers at a Trusted Validator (TVAL). The TVAL performs a one-time validation of the TS's identity, and creates a public access URL and private application key for the TS. The TS uses the private application key to generate, for each email message/address pair, a unique message access URL. The message access URL is inserted, along a text containing instructions, at the top of the email message to be sent. The public access URL is published by the TS (typically at the TS's web site) for the message receiver (MR) to associate the TS with his/her account in the TVAL. The MR obtains an authentication cookie for his/her email address at the TVAL, and, for each TS, he/she registers a “key phrase” only known to the MR in relationship with the TS.
