Encryption of digitized physical information based on physical tags

摘要

Methods and apparatus for encrypting an image produced from physical information. The physical information may be associated with a physical tag that identifies a public key. The physical information may be digitized to create a digital image, and the physical tag may be digitized to create a digital tag that is readable to identify the public key. The digital tag may be read to identify the public key, and then the image encrypted with the identified public key.
