Using Payment Gateways to Maintain Privacy in Secure Electronic Transactions
[chapter]
2007
IFIP International Federation for Information Processing
Preserved Fulltext
In this paper, we introduce a third party payment system that aims to preserve privacy by severing the link between their purchase and payment records, while providing a traceable transaction that maintains ...
One solution to this problem was SET, but it was never really a success because of its complexity and poor reception from consumers. ...
Thus, the status quo presents great privacy and security risk to the consumer. In this paper, we re-examine the use of a third party payment service. ...

Know your customer (KYC) processes place a great burden on banks, because they are costly, inefficient, and inconvenient for customers. ...
We follow a rigorous design science research approach to create a framework that utilizes SSI in the KYC process, deriving nascent design principles that theorize on blockchain's role for SSI. ...
Thereby, only the statuses of completed KYC processes are stored on a blockchain. ...
