Cost-Effective Payment Schemes with Privacy Regulation
نویسنده
چکیده
In this paper, we introduce a new electronic money methodology: sub-contracting the blinding to a trustee and using an Identitybased piece of information to achieve provable privacy and security. This variation on the Brickel, Gemmel and Kravitz paradigm [2] offers protection against various attacks minimizing user’s computational requirement. Furthermore, our scheme offers various complexity/privacy tradeoffs without endangering the issuer’s overall security.

An approach is present which integrates an economic and an ecological model for designing cost-effective compensation payments for conservation of endangered species in real landscapes. The approach is used to develop a cost-effective compensation payment scheme for conservation of an endangered butterfly species (Maculinea teleius) protected by the EU Habitats Directive in the region of Landau...
متن کاملAn Efficient E-Payment Scheme
The present e-payment schemes permit anonymity property to protect customer privacy. However, the majority of these schemes have not offered a non-denial property. For example, several difficulties subsist in the schemes such as repudiation, loss, abuse, theft, and overspend-tracing. This article suggests an e-payment scheme wherein a temporary anonymous public key is embedded in a partial blin...
متن کاملMix-Based Electronic Payments
We introduce a new payment architecture that limits the power of an attacker while providing the honest user with privacy. Our proposed method defends against all known attacks on the bank, implements revocable privacy, and results in an efficient scheme which is well-suited for smartcard-based payment schemes over the Internet.
متن کاملZerocash: Decentralized Anonymous Payments from Bitcoin (extended version)
Bitcoin is the first digital currency to see widespread adoption. Although payments are conducted between pseudonyms, Bitcoin cannot offer strong privacy guarantees: payment transactions are recorded in a public decentralized ledger, from which much information can be deduced. Zerocoin (Miers et al., IEEE S&P 2013) tackles some of these privacy issues by unlinking transactions from the payment’...
