  • Anonymous and secure internet payment method and mobile devices
    Patent number: 7630927
    Abstract: An anonymous and secure on-line payment system and method based on the partially blind signature cryptographic method with revocable anonymity. To this end, an Anonymity Server (SA) enables the Customer (C) to acquire on-line anonymous payment means on the basis of a protocol that does not enable the Anonymity Server to link the payment means to the Customer (C). The Payment Server (SdP) comprises means for opening an anonymous account using the anonymous payment means (50). A Customer (C) can make an on-line purchase from a Merchant Site (SM) without having to give a bank card number and remaining anonymous to the merchant and more generally to any entity present in the transaction or absent therefrom. However, this anonymity may be revoked by a trusted entity in the event of fraud on the Customer. Finally, a Customer can make payments when on the move.
