Abstract
Systems and methods are disclosed that receive data at an electronic computing device. A first algorithm can be applied to the phrases to generate masked versions of the phrases. The masked versions can be cryptographically secured using a second algorithm and a cryptographic key. The second algorithm and cryptographic key can be used to generate a secured versions of the phrases. A filter representative of the data can be generated using the secured versions of the phrases.
