Abstract

An individual authentication and digital signature system utilizing an article having an identification mark that encodes genome related information capable of identifying an individual to be identified is disclosed. The identification mark can be provided in a form of a two dimensional bar code or an IC equipped medium. The identification mark can be printed by using DNA mixed ink containing DNA or DNA fragment directly acquired from the individual. The article can also have a recording medium for recording the genome related information, which can be an IC chip provided on the article. The genome related information obtained from the identification mark, the DNA mixed ink and the recording medium can be used in authenticating the individual, the article, or a product to which the article is to be attached.
