A camera, a system for detecting an optical identity tag and a method for identification

A system for detecting an optical identity tag, comprising:

• a camera, having a lens, an image sensor receiving light from the lens,
• and a cover glass for the image sensor on an optical path between the lens and the image sensor;
• and
• an optical identity tag placed outside the camera and configured to be captured by the camera,
• wherein
• the optical identity tag comprises a security hologram configured to reflect rays of light in a first predefined light pattern;
• the cover glass comprises an identification marker at the optical path, wherein the identification marker is configured to block rays of light to reach a portion of the image sensor;
• and
• the identification marker is configured to alter the first predefined light pattern into a second predefined light pattern, when the first predefined light pattern is reflected from the optical identity tag to the identification marker.

A method for identification, comprising:

• a camera, having a lens, an image sensor receiving light from the lens;
• and a cover glass for the image sensor on an optical path between the lens and the image sensor;
• the cover glass comprises an identification marker at the optical path blocking rays of light from reaching a portion of the image sensor;
• and
• the method comprises the steps of:
• allowing light to travel along the optical path;
• and
• marking an image captured by the camera by a pattern caused by the identification marker to the image sensor.
