Abstract
Systems and methods that permit the querying of encrypted data in a cryptographically-secure manner. Generally, data that has been encrypted cannot be queried using plaintext terms because it is in ciphertext. Accordingly, use of filters that correspond to the encrypted data and are generated by multiple parties permits querying of the data without decrypting the data or compromising the security of the encrypted data or of the queries against that data.
