Described herein is a payment transaction system (100) in which a payment transaction is authenticated using an alias. When procuring an item from a supplier (120), a customer (110) needs to provide payment in some form or the other. Profiles relating to both the customer (110) and the supplier (120) are stored in an environment managed by a broker (130) and payment is effected by transfer of within that environment from a customer wallet to a supplier wallet. The customer (120) is represented as an alias as far as the supplier (120) is concerned. In one embodiment, the alias is provided by a data structure configured in accordance with an electronic representation of a medium of exchange. In an alternative embodiment, the alias is provided by an external identity provider (140) such as a social network with which the customer (120) is associated. In each embodiment, the anonymity of the customer (120) is maintained with respect to the supplier (120). |
