Abstract: The present invention relates to the identification of an individual to other entities. A certifying authority verifies the identity of an individual. Upon authentication, the certifying authority issues a multiple purpose card with the individual's information, a public key and a private key associated with the user. The certifying authority indicates the revoking of the digital certificate by removing it from the access active list. Technology can be used for good or evil. However, as understanding builds upon understanding, technology has unintended consequences not foreseen by the inventors. Our hope is that this technology is only used for the purpose of increasing the quality of life for humans.
