Abstract
Personal data may be embedded in a kinegram of an identification document using a suitable low energy laser without compromising the integrity of the kinegram or the identification document. The personal data can be written in a metalized portion of the kinegram in a high definition, high resolution manner such that the personal data may be read by a human without the use of a text-enhancing viewer device (e.g., magnifying glasses). Additional personal data can be written in a reduced text size (e.g., micro-text) in another metalized portion of the kinegram such that a human must use a text-enhancing viewer device to view the micro-text personal data.
Claims30
A method to embed a security feature into an identification document for identifying a person holding the identification document, the method comprising:
- placing the identification document to receive laser irradiation, wherein a metalized structure is inside the identification document and is coated with metal;
- focusing a laser beam on a portion of the metalized structure;
- irradiating the portion of the metalized structure such that metal is removed from the portion of the metalized structure at the focus of the laser beam;
- and
- creating a spatial pattern in the metalized structure by refocusing the laser beam to irradiate at least one more portion of the metalized layer, the created spatial pattern including a feature to identify the holder of the identification document.
A method to embed a security feature into an identification document identifying a holder of the identification document, the method comprising:
- applying a laser beam on a portion of a metalized structure embedded within an identification document, the metalized structure comprising an opaque material and being embedded below an external surface of the identification document;
- removing metal from the portion of metalized structure in response to applying the laser beam;
- and
- creating a spatial pattern in the metalized structure by applying the laser beam to at least one more portion of the metalized structure, the created spatial pattern comprising one or more features that correspond to identification information associated with the holder of the identification document and that are visible from a front side and a rear side of the identification document.
