Abstract

The present invention relates to an identification document for a subject. The identification document includes a substrate, and a visual image formed on the substrate. The visual image includes a face image of the subject in a first area, and invisible but retrievable embedded information formed in the face image in the first area but not formed in a second area of the visual image. The embedded information corresponds to the identity of the subject and is usable to identify the subject.

Claims

1. An identification document for a subject, comprising:

a) a substrate;

b) a visual image formed on the substrate or a recording layer over the substrate, such visual image including at least a face image of the subject in a first area; and

c) invisible but retrievable embedded information formed in the face image in the first area but not formed in a second area of the visual image, such embedded information corresponding to the identity of the subject and being usable for identifying the subject.

2. An identification document for a subject, comprising:

a) a substrate;

b) a visual image formed on the substrate or a recording layer over the substrate, such visual image including at least a face image of the subject in a first area;

c) invisible but retrievable embedded information formed in the face image in the first area but not formed in a second area of the visual image, such embedded information corresponding to the identity of the subject; and

d) visual textual information in the second area for identifying the subject wherein such textual information corresponds to the identification information in the embedded information such that the correspondence of the two information can be used for verification purposes.

3. An identification document for a subject, comprising:

a) a substrate;

b) a visual image formed on the substrate, such visual image including at least an image of the subject in a first area; and

c) invisible but retrievable embedded information formed in the image in the first area but not formed in a second area of the visual image, such embedded information corresponding to the identity of the subject and being usable for identifying the subject.

4. An identification document for a subject, comprising:

a) a substrate;

b) a visual image formed on the substrate, such visual image including at least a face image of the subject in a first area;

c) invisible but retrievable embedded information formed in the face image in the first area but not formed in a second area of the visual image, such embedded information corresponding to the identity of the subject; and

d) visual information in the second area for identifying the subject wherein such visual information corresponds to the identification information in the embedded information such that the correspondence of the two information can be used for verification purposes.
