A data collection system having a touch screen and sensors behind the touch screen for obtaining biometric data about the user. The holder includes a longitudinally extending first retaining member and a longitudinally extending second retaining member spaced-apart from the first member and being interconnected on respective first ends thereof by a laterally extending base member. This invention treats the design of target matching-templates and target matched-filters for image correlation as a statistical pattern recognition problem. In a more general case, the encrypted data is sent over one channel, and the encryption information is divided and sent over several other channels.
