29 * TAF - Transmutative Assertion Framework.
\r
31 * This main Interface embodies the essential of the assertion, where a number of different TAFs might be used to authenticate
\r
32 * and that authentication to be recognized through other elements.
\r
34 * Concept by Robert Garskof. Implemented by Jonathan Gathman
\r
38 public interface Taf {
\r
39 enum LifeForm {CBLF, SBLF, LFN};
\r
41 * The lifeForm param is a humorous way of describing whether the interaction is proceeding from direct Human Interaction via a browser
\r
42 * or App which can directly query a memorized password, key sequence, bio-feedback, from that user, or a machine mechanism for which identity
\r
43 * can more easily be determined by Certificate, Mechanical ID/Password etc. Popularized in modern culture and Science Fiction (especially
\r
44 * Star Trek), we (starting with Robert Garskof) use the terms "Carbon Based Life Form" (CBLF) for mechanisms with people at the end of them, or
\r
45 * "Silicon Based Life Forms" (SBLF) to indicate machine only interactions. I have added "LFN" for (Life-Form Neutral) to aid identifying
\r
46 * processes for which it doesn't matter whether there is a human at the immediate end of the chain, or cannot be determined mechanically.
\r
48 * The variable parameter is not necessarily ideal, but with too many unknown Tafs to be created, flexibility,
\r
49 * is unfortunately required at this point. Future versions could lock this down more. JG 10/18/2012
