Abstract: A data-processing technique for increasing data-size capacity and improving query speed on large datasets where fields within records are replaced by integers representing distinct values of those fields, the integers drawn from a densely-populated range, wherein a computer data storage structure is initialized and maintained to represent a large number of binary values (“bits”) within a smaller number of actual machine-memory bits of the computer. Representative structures and operations thereon, as well as applications of the data structure to support more-sophisticated data structures and operations, are described and claimed.

Abstract: Methods to detect and hamper or thwart noncompliant access to online data examine access patterns, history and statistical records, and which may send no, incorrect or nonsense data if data harvesting is detected.
