ABSTRACT:
Coded data for disposal on or in a surface that includes a number of coded data portions. Each coded data portion encodes an identity of an object or the like associated with the surface. In addition, each coded data portion encodes at least part of a signature that is a digital signature of at least part of the identity and at least part of predetermined padding. This allows the coded data to be used to both identify and authenticate the object.
