A large number of people digitally sign the same document. The signature collectors want to use only a small amount of memory to demonstrate to any third party approximately how many persons have signed it. The scheme described in this paper uses a non-uniform secure hash function to select a small subset of signatures that the collectors store. The size of this subset becomes a verifiable estimate for the logarithm of the number of signers. Applications for this scheme range from Web page… CONTINUE READING
