A biometric method and system for personal authentication using sequences of partial fingerprint signatures provides a high security capability to various processes requiring positive identification of individuals. The intermediate film includes at least two layers, i. A front light-guiding unit 8d has a facing surface that faces the rear light-guiding unit 8c and a tip-end face 8a exposed when inserted in a through hole, and a linear shape is formed between these surfaces. The tokenskeys may be derived directly from the contextual information. The catalytic partial oxidation reactor contains a platinum group catalyst, a promoted platinum group catalyst, a rhodium catalyst, or a platinum promoted rhodium catalyst. Through the use of a bioinformatics strategy, mammalian members of the of PTK’s and STK’s have been identified and their protein structure predicted.
