Using Payment Gateways to Maintain Privacy in Secure Electronic Transactions [chapter]

Alapan Arnab, Andrew Hutchison
2007 IFIP International Federation for Information Processing  
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.  ...

Marc-Michael Bergfeld, Holger Bock, Roderick Bloem, Jan Blonk, Gregory Conti, Kurt Dietrich, Matthias Junk, Florian Schreiner, Stephan Spitz, Johannes Winter
2012 Lecture Notes in Computer Science  
In our prototype, we only sign the key and send the key plus the DAA signature to the host instead of a X.509 certificate and the according chain.  ...  The signing party which signs the DAA parameters could also be the vendor, however, at the cost of an extra service and additional processing steps on the platform required for validating the parameters  ...

Designing a Framework for Digital KYC Processes Built on Blockchain-Based Self-Sovereign Identity

Vincent Schlatt, Johannes Sedlmeir, Simon Feulner, Nils Urbach
2021 Information & Management  
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.  ...

Data Confidentiality In P2P Communication And Smart Contracts Of Blockchain In Industry 4.0 [article]

Jan Stodt, Christoph Reich
2020 arXiv   pre-print
It realizes data confidentiality of P2P communication and data processing in smart contracts of blockchains.  ...  We show that previous blockchain based privacy protection approaches offer protection, but give the control of the data to (potentially not trustworthy) third parties, which also can be considered a privacy  ...  To establish consensus of the certification status, each entity participates in a voting process via smart contracts.  ...

Sybil Attack Detection Based on Authentication Process Using Digital Security Certificate Procedure for Data Transmission in MANET

P Muthusamy, T Sheela
2018 International Journal of Engineering & Technology  
To detect the sybil node during the route discovery process, the nodes authenticate each other by providing the digital security certificate (DSC).  ...  The proposed system ensures the availability, confidentiality, authenticity and reliability of the information using digital certificate chains and secret sharing schemes.  ...  The Privacy-Preserving Detection of Sybil Attacks Attackers have more computational power and canalter their transmission signal strength.  ...

Non-Repudiation in Internet Telephony [chapter]

Nicolai Kuntze, Andreas U. Schmidt, Christian Hett
2007 IFIP International Federation for Information Processing  
The method rests on chained electronic signatures applied to pieces of packet-based, digital, voice communication.  ...  This has the advantage to store and transport certificates and certificate chains in combination with the data.  ...  On the other hand, a compromised Arc does not posses the certificate.  ...
