Problems solved by technology

[0006] In addition, various data images and data cards themselves are flawed
For example, the data image is easily scratched, polluted or peeled off, and the scanner cannot identify the target
Once the electronic materials of various data cards fail (such as degaussing of magnetic cards), or the electronic circuits (such as IC) are damaged, they will immediately become useless cards, and even the authenticity of the cards themselves will become a problem.

example

[0068] Here is a specific example to preliminarily illustrate the labeling method and feasibility of chemical markers:

[0069] Add a chemical element mark on the base (paper base) of a data card, irradiate the paper containing the mark with energy, and scan it with an X-ray fluorescence detector to obtain the X-ray fluorescence spectrum of the paper, as shown in Figure 3. Among them, peaks 1 and 2 are other components of paper, and peak 3 is the peak marked by this chemical element.

[0070]Subsequently, let the paper base burn, and after it stops burning by itself, scan the residue with an X fluorescence scanner again to obtain the X fluorescence spectrum of the paper after burning, as shown in Figure 4: the above two spectra comparing,

[0071] It can be clearly seen that even if the state of the data image and the data card itself is changed (or even burned), the mark will not be changed, and it can be completely preserved. Will exist on even corrupted data images and da...

Abstract

A protective method for data image or data card comprises the following steps: a test mark for protecting the data image or data card is defined, and the mark comprises at least one chemical element selected from inherent chemical elements of the data image or data card and / or extra chemical elements; a database comprising the data of the mark is provided; the signal transmitted by the data image or data card is tested to generate test data which is compared with the data in the database; according to comparison results, scanning of the data image or data card goes on if the data image or data card to be tested is judged true according to the database, while the scanning of the data image or data card stops if the data image or data card to be tested is judged false according to the database. The invention also provides related equipment and systems.

Description

technical field [0001] The invention relates to a method, device and system for protecting and detecting data cards and data images. Background technique [0002] Human life is increasingly digitized, and various data images and data cards have been widely used. In the present invention, "data image" refers to various images printed with data marks on the substrate, such as various barcode labels and the like. "Data card" refers to various cards carrying various functional electronic materials or electronic circuits on the substrate, such as various magnetic cards, photoelectric cards, IC cards, etc. [0003] Digitization has brought speed and convenience to people's life, but it also brings danger. Modern criminal methods include stealing, forging, and cracking various digital information to achieve criminal purposes. [0004] Data images are relatively easy to forge. For example, barcodes are used in almost all commodities sold in large and small supermarkets, and manu...
