Abstract

Material code recording and reading method and devices designed for protection of products and control of their authenticity. The marking device 1 embeds a sign upon the product 4, the marked product 5 is passed to camera 2 which films the product material structure around the sign and transfers the image to the recording device 3, the latter records the database. The comparing alarm device 8 compares the icon from camera 7 with the icon from database 6 and alarms whether they are identical or not.

Claims

1. A method for recording and reading a structure of the original material of products for protection and control of their authenticity, comprising:

embedding a sign upon the original product,

passing the original product to a camera to film the product material structure around the sign,

recording the filmed image in a database,

comparing the image recorded in the database with another image from another camera, and

differentiating the original product from exact copies thereof by a unique structure of the original material of the product around the sign embedded upon the original product, which is a code of material of the product,

wherein the sign serves as a reference point of which part of the original material is to be scanned for authentication purposes, wherein a part or a whole of the product material structure around the embedded sign is filmed and used for authentication.

2. The method according to claim 1, wherein the sign is embedded by means of a printer, a laser, or a punching machine.

3. A system for recording and reading a structure of the original material of products for protection and control of their authenticity, comprising:

a marking device (1) to embed a sign upon the original product (4);

a camera (2) to film the product material structure around the embedded sign of the original product (5);

a recording device (3) to record the filmed image in a database (6);

the database (6);

a camera (7) to film the product material structure around the embedded sign of the original product (5); and

a comparing and alarm device (8) to compare an image from the camera (7) with the image from the database (6) and alarm whether they coincide or not,

wherein the comparing and alarm device (8) differentiates the original product from exact copies thereof by a unique structure of the original material of the product around the sign embedded upon the original product, which is a code of material of the product,

wherein the sign serves as a reference point of which part of the original material is to be scanned for authentication purposes, wherein a part or a whole of the product material structure around the embedded sign is filmed and used for authentication.

4. The system according to claim 3, wherein the sign is embedded by means of a printer, a laser, or a punching machine.
