US Patent 10354078 Multi-focused fine-grained security framework

An approach is provided in which a knowledge manager generates a knowledge structure that includes security annotation tokens and term tokens. Each of the security annotation tokens are stored in a parallel field and align to at least one of the term tokens. The knowledge manager matches security policies corresponding to a search request to one or more of the security annotation tokens and, in turn, generates search results based upon obfuscation of one or more of the term tokens aligned to the matched security annotation tokens.
