Trusted Data Format
The Trusted Data Format (TDF) is a data object encoding specification for the purposes of enabling data tagging and cryptographic security features. These features include assertion of data properties or tags, cryptographic binding and data encryption. The TDF is freely available with no restrictions and requires no use of proprietary or patented technology and is thus open for anyone to use. Overview The TDF Specification is based on a Trusted Data Object (TDO) which can be grouped together into a Trusted Data Collection (TDC). Each TDO consists of a data payload which can be associated with an unlimited number of metadata objects. The TDO supports the cryptographic binding of the metadata objects to the payload data object. In addition, both data and metadata objects can be associated with a block of encryption information which is used by any TDF consumer to decrypt the associated data or metadata if it had been encrypted. A TDC allows for additional metadata objects t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ODNI
The director of national intelligence (DNI) is a senior, cabinet-level United States government official, required by the Intelligence Reform and Terrorism Prevention Act of 2004 to serve as executive head of the United States Intelligence Community (IC) and to direct and oversee the National Intelligence Program (NIP). All IC agencies report directly to the DNI. The DNI also serves, upon invitation, as an advisor to the president of the United States, the National Security Council and the Homeland Security Council on all intelligence matters. The DNI, supported by the Office of the Director of National Intelligence (ODNI), produces the President's Daily Brief (PDB), a top-secret document including intelligence from all IC agencies, handed each morning to the president of the United States. President George W. Bush strengthened the role of the DNI on July 30, 2008, with Executive Order 13470, which, among other things, solidified the DNI's authority to set goals for intelligence ...

Logical Assertion
In mathematical logic, a judgment (or judgement) or assertion is a statement or enunciation in a metalanguage. For example, typical judgments in first-order logic would be ''that a string is a well-formed formula'', or ''that a proposition is true''. Similarly, a judgment may assert the occurrence of a free variable in an expression of the object language, or the provability of a proposition. In general, a judgment may be any inductively definable assertion in the metatheory. Judgments are used in formalizing deduction systems: a logical axiom expresses a judgment, premises of a rule of inference are formed as a sequence of judgments, and their conclusion is a judgment as well (thus, hypotheses and conclusions of proofs are judgments). A characteristic feature of the variants of Hilbert-style deduction systems is that the ''context'' is not changed in any of their rules of inference, while both natural deduction and sequent calculus contain some context-changing rules. Thus, if w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
