Abstract

Methods and systems enable receiver devices to receive electronic coupons from mobile TV broadcast service providers. Coupon templates may be broadcasted to mobile devices. Coupon templates may be used to communicate with coupon managers to receive digitally signed coupons. Coupon managers may use received data to create digitally signed coupons for delivery to receiver devices via a unicast networks. Digitally signed coupons may also be broadcasted to receiver devices. A receiver device may verify received electronic coupons using the digital signature to identify those coupons intended for them. The electronic coupons may be redeemed at a point of sale. Merchants may locally verify coupons using their digital signature. Coupon digital signatures may be generated using a chain of X.509 certificates leading to a root X.509 coupon-signing authority to enable recipients to confirm that coupons originated from a trustworthy entity.
