CRC 901 - Practicable Cryptographic Techniques for Secure and Data-efficient Customer Loyalty Systems (Transfer project T2)
Overview
In subproject a new customer loyalty system for the retail sector will be developed and evaluated. Compared to existing systems, which are expensive and expensive, lack transparency and require trust in the operator, the new system will set new standards in terms of security, privacy, and economic efficiency. To achieve this goal the cryptographic techniques credentials and attribute-based signatures developed in subproject C1 will be enhanced and optimized for the application in a customer loyalty systems. Diebold Nixdorf, as a service provider for the retail sector, will realize and evaluate the new system in its store infrastructure.
