Abstract: The present disclosure describes digital watermark detection systems and methods. In one such system, a plurality of intellectual property cores are integrated on a system-on-chip, such that the intellectual property cores comprise a first intellectual property core and a second intellectual property core. The system further includes a first network interface connected to the first intellectual property core that can encode a first digital watermark into a packet stream designated for the second intellectual property core. The system further includes a second network interface connected to the second intellectual property core that can receive the packet stream and decode the packet stream to generate a second digital watermark. The second network interface is further configured to perform a validation test on the packet stream and deliver the packet stream to the second intellectual property core when the first digital watermark is determined to match the second digital watermark.

Abstract: A method is provided for generating an encrypted database. The method includes: receiving a plaintext database having plaintext data entries therein; and generating an encrypted database using the plaintext database, the encrypted database including encrypted data entries therein. The encrypted database is configured to support at least one form of conditional query such that the at least one form of conditional query returns a correct encrypted result when the query is computed on the encrypted data entries without the decryption thereof.

Abstract: A method is provided for generating an encrypted database. The method includes: receiving a plaintext database having plaintext data entries in one or more columns; augmenting the received plaintext database to generate an augmented plaintext database, the augmenting including the addition of one or more columns to the received plaintext database, each added column corresponding to an attribute which is to be made available for conditional queries; and encrypting the augmented plaintext database to generate the encrypted database including encrypted data entries. The encrypted database supports at least one form of conditional query for those attributes corresponding to the added columns, the at least one form of conditional query being computed on the encrypted data entries without the decryption thereof to produce an encrypted result.

Abstract: One embodiment provides a system for noise addition to enforce data privacy protection in a star network. In operation, participants may add a noise component to a dataset. An aggregator may receive the noise components from the plurality of participants, compute an overall noise term based on the received noise components, and aggregate values using the noise components and overall noise term.
