Identity document comprising a ghost image based on a two-dimensional image

An identity document (1) comprising:

• in a single plane a two-dimensional portrait image (A) and under optical means a ghost image (D) for verifying authenticity of the two-dimensional portrait image (A),
• wherein the ghost image (D) is a stereo image (5) that is based on the two-dimensional portrait image (A),
• wherein the ghost image (D) comprises the two-dimensional portrait image (A) per se,
• wherein the two-dimensional portrait image (A) shows a person, and the ghost image (D) shows a person being the same person as shown by the two-dimensional portrait image (A),
• wherein the ghost image (D) comprises more than two images of the person on the identity document (1) of which at least one of the more than two images is a calculated image that is rotated over an angle in the range from 4.5° to 7.5°, the more than two images being interlaced, and a floating image (20) arranged to appear to float over the ghost image (D),
• wherein the optical means comprise a series of linear lenticular lenses (8, 9, 10) forming a lens array (7) and said lenses (8, 9, 10) are cylindrical shaped, the lenses (8, 9, 10) extending in the direction of the symmetry axis of the face of the person, the images being formed by focusing a laser beam via the lenses and a carbonizing image layer material, and
• wherein the two dimensional portrait image (A) and the stereo image are recognizable as the same person and can be compared by an inspecting person without tilting the identity document for establishing authenticity of the two-dimensional portrait image (A).
