Abstract

A method and system is disclosed for embedding micro markers into materials for unique identification of manufactured objects. The embedded micro-markers in the material are randomly distributed in three dimensions within the manufactured object. The arrangement of the embedded micro-markers in the material provides a unique signature that is used to verify authenticity of the manufactured object.

System and Method for Embedding Micro Markers into Materials for Unique Identification of Manufactured Objects

Disclosed is a method and system for embedding micro markers into materials for unique identification of manufactured objects. The embedded micro-markers in the material are randomly distributed in three dimensions within the manufactured object. The arrangement of the embedded micro-markers in the material provides a unique signature that is used to verify authenticity of the manufactured object.

In accordance with the method and system, micro-markers are mixed with a raw material that is used to manufacture an object. The manufacturing of the object may involve, one or more of, but not limited to, 3D printing technologies, additive manufacturing processes, casting and molding processes and machining of stock raw materials. The mixing of the micro-markers may depend on any specific manufacturing process for a particular kind of raw material. The micro-markers may be mixed either prior to the manufacturing process or during the manufacturing process. The micro-markers are mixed to obtain an even average density of micro-markers within the raw material. In an embodiment, the micro-markers may be distributed within a specific area within the manufactured object. This may provide structural strength to the object or assist in scanning the micro-markers. The micro-markers are distributed in three dimensions within the manufactured object as illustrated in Figure 1.

Figure 1

After the completion of the manufacturing process, each object is then scanned and the three- dimensional positions of the micro-markers within the manufactured object are recorded. The three dimensional positions of micro-markers may be determined using vector data for each micro-marker as illustrated in Figure 2.

Figure 2

The scanning of the manufactured objects displays position data of the micro-markers along one or more axis in the three dimensional plane as illustrated in Figure 3.

The recorded position data uses the micro-markers positions' relative to specific points on or within the manufactured object. Alternately, the recorded position data may rely solely on the relative positions of the micro-markers alone, without relation to points on or within the manufactured object. This enables identification of the manufactured obje...
