We introduce a new type of commitment schemes, called visual commitment schemes.
Since all data are printed as black and white images on transparencies,
checking data and recovering a messageare done only by piling up transparencies.
Hence,visual commitment schemes do not require users to have cryptographic knowledge and to perform cryptographic operations.
Visual commitment schemes proposed in this paper are based on the trusted-initializer model,and are unconditionally secure. |
