Abstract

A method of processing semiotic data includes receiving semiotic data including at least one data set P, selecting a function h, and for at least one of each data set P to be collected, computing h(P), destroying data set P, and storing h(P) in a database, wherein data set P cannot be extracted from h(P). The method further includes selecting a private key/public key (K, k) once for all cases, one of destroying the private key K and sending the private key K to a trusted party, and choosing function h as the public encryption function corresponding to k.
