description The invention relates to a cryptographic system (010) for performing a fuzzy string matching in a privacy-preserving way as a cryptographic secure multi-party computation between multiple cryptographic devices. Input devices apply a string-to-vector model to input strings to obtain vector representations, and provides the vector representations as inputs to the multi-party computation. A cryptographic device obtains the vector representations as inputs to the multi-party computation and computes under the multi-party computation distances between the vector representations. The distance is used as an indicator of a fuzzy string matching between the input strings.
