  • Patent number: 9846785
    Abstract: A querying node generates public keys, secret keys, and switch key matrices. A public key associated with a first level and the switch key matrices are sent to a receiving node. The receiving node generates a key-value table, mapping values to keys, and encodes the keys and values using a polynomial ring of a predetermined type. The querying node encodes using a polynomial ring of the same predetermined type, then encrypts a query, using a public key, and sends the query to the receiving node. The receiving node performs a homomorphic comparison of the encrypted, encoded query with each encoded key entry in the encoded key-value store to determine a comparison result. The receiving node sums the results for each of the value entries and returns the summed result to the querying node. The querying node decrypts and decodes the received result using the corresponding secret key.

  • Publication number: 20170344633
    Abstract: Systems and methods provide for classification and ranking of features for a hierarchical dataset. A hierarchical schema of features from the dataset is accessed. A hierarchical rank is assigned to each feature based on its schema level in the hierarchical schema. Additionally, a semantic rank is assigned to each feature using a semantic model having ranked semantic contexts. The semantic rank of a feature is assigned by identifying a semantic context of the feature and assigning the rank of the semantic context as the semantic rank of the feature. A rank is computed for each feature as a function of its hierarchical rank and semantic rank.
