    摘要: A content-based information retrieval architecture is herein disclosed that can achieve correct and predictable high speed lookups while taking advantage of inexpensive conventional memory components. A content-based information retrieval architecture is herein disclosed that can achieve high speed lookups with a constant query time while taking advantage of inexpensive conventional memory components. In accordance with an embodiment of the invention, the architecture comprise a hashing module, a first table of encoded values, a second table of lookup values, and a third table of associated input values. The input value is hashed a number of times to generate a plurality of hashed values, the hashed values corresponding to locations of encoded values in the first table. The encoded values obtained from an input value encode an output value such that the output value cannot be recovered from any single encoded value.

    摘要: In a multiparty verification system, a prover and a verifier are coupled torocess respective outputs to provide a system output such as an identification verification. The prover is formed of plural units which share confidential information used to encrypt information carried by the prover. Communication between the prover units is prevented. The first prover unit encrypts the information based on additional information received from the verifier and transfers the encrypted information to the verifier. Subsequently, the verifier obtains from the second prover unit the shared confidential information required to decrypt a subset of the transmitted encrypted information.
