Abstract: Systems and methods for augmenting, inferring, extrapolating, deducing, reasoning, and storing logical networks of information represented in digest form are disclosed. The disclosed systems and methods enable the combined inclusion of both sensitive information and non-sensitive information into a compressed, universal, indiscernible format. Relationships can be derived or inferred between unintelligible digests of information by associating them with a common underlying entity. A universal digest format described herein may become comprehensible by further utilizing additional a priori or a posteriori knowledge of the information such that recognized digests can be utilized fully while unknown and potentially sensitive digests remain undecipherable.
