  Paper Title

Exploring A Cryptographic Sollution in Blockchain for Privacy and Preserving Auction System

  Authors

  Mavilla Pavithra,  Mr.A.J.Rajasekhar

  Keywords

Blockchain, DME

  Abstract


This paper addresses the privacy concerns in blockchain-based bidding systems, where bidding records, once stored, become immutable and visible only to the bidder and seller. However, this security measure falls short in cases of coercion, potentially compromising user privacy. To mitigate this, we introduce Deniable Matchmaking Encryption (DME), enhancing privacy by providing deniability for both messages and identities. Utilizing the chameleon hash function, our scheme ensures that fake messages and identities are indistinguishable from real ones. As an extension, our modified DME algorithm enables all bidders to decrypt and view the winning notification, safeguarding both the winner's identity and the transparency of the bidding process, thereby preserving user privacy while maintaining system integrity.
