Abstract
Security is provided to electronically performed transactions by authenticating transaction instruments (such as electronic coupons, electronic receipts and electronic vouchers such as electronic tickets) that are utilized by a customer in a transaction, such as by a participating customer in a loyalty program. In an electronic wallet application provided on a mobile communication device, for example, digital signatures are applied to verify the authenticity of such transaction instruments when communicated between the communication device and a gateway that effectuates such transactions and defines, manages, distributes, processes and/or applies the corresponding transaction instruments. Digital signatures may also be applied to verify the authenticity of transaction instruments and related data when communicated between the gateway and other entities or systems.
