What kind of camera should be installed on the production line?
It is recommended that product manufacturers use an industrial camera to ensure high quality images. Cameras meeting the requirements have a resolution of >10 Mega pixels, industrial lenses, and illumination equipment. Bosch Building Technologies, for example, has suitable cameras on offer. We are also happy to provide you with the hardware if you so require.
When comparing two visually identical products, we can safely assume that they are not clearly distinguishable from each other. But while it might be hard to differentiate them at first glance, a closer look reveals that every item possesses some unique features. Take industrial pumps as an example — there are many processes involved in their manufacture, from carving through to polishing. All of these processes leave traces on the surface that make pumps uniquely distinguishable.
These small variations form the basis of the Natural Fingerprint, the second component of the Secure Product Fingerprint solution. The way it works closely resembles the Artificial Fingerprint, except that in this case the product itself is used for validation. To implement the Natural Fingerprint, the manufacturer has to specify a surface area of the product to be used for verification and then take a picture of it. This can be done by installing a camera at the production line. The camera is then set up to automatically take a picture of the designated “fingerprint” area. The image is stored in the cloud and used for comparison later on.
When customers receive the product, they take a picture of the same area – again, a regular smartphone camera suffices. The image is then uploaded to the cloud where an algorithm compares it to the original “fingerprint” to validate the product. This method guarantees the highest protection against counterfeiting.
