Three Steps to Laser Marking Security

The three practical solutions it provides to this problem are: optimizing the laser marking process, introducing dynamic encryption technology, and establishing an intelligent detection system.By upgrading the materials and methods used to verify the authenticity of the codes, companies can increase the security of their anti-counterfeiting codes, lower the risk of counterfeiting, and safeguard the reputation of their products in the marketplace.

Why would anyone bother to fake a laser security code?

Most laser marking systems available on the market today use fixed patterns, such as simple logos or serial numbers.With sophisticated scanning equipment, counterfeiters can easily replicate the surface texture of the labels, and they can even use chemical corrosion to mass-produce counterfeit labels.Last year one cosmetics company saw a 37 % increase in counterfeits when its anti-counterfeiting code was cracked.

Three-step anti-counterfeiting technology

Materials and technology both underwent a revolution.

It is suggested that multi-layered composite materials be chosen, such as PET film with metal micro-particles embedded in it.When exposed to laser light, the material forms a three-dimensional microstructure on the surface, like a fingerprint.A test by a certain electronics parts manufacturer showed that the technique increased the cost of counterfeiting 12-fold.

Dynamic encryption and authentication system.

The anti-counterfeiting code can be tied to a dynamic verification channel, such as requiring the user to enter a real-time verification code or to complete facial recognition after scanning.Don't rely on static databases to validate the codes, because in last year's incident with counterfeit wine, hackers copied the entire batch of valid codes directly.Some brands are now using blockchain to store information. Every time the information is looked at, an unalterable record is left.

Intelligent testing made routine.

The company has installed AI quality control equipment on its assembly line that uses spectral analysis to monitor the quality of its products in real time.A pharmaceutical company randomly samples 3,000 labels each week, using a microscope to compare the laser spots and the melting condition. This brings the error rate down from 0.5 % to 0.02 %.Remember to regularly update your detection algorithms, because the techniques of forgers don't stand still.

Maintenance points to consider.

Every month the output power stability of the laser is checked. If the power fluctuates more than ± 5 %, it has to be immediately calibrated.The relative humidity in the warehouses where labels are stored should be kept between 40 % and 60 %, since too dry an environment will cause the base material to become brittle.Last year, for example, a food company's warehouse air conditioning system malfunctioned, causing a batch of counterfeit-proof labels to crack.

Don't forget to involve distributors in anti-counterfeiting training. Many counterfeiting loopholes actually come from the distribution process.You can make a book that shows the difference between the real and fake versions, and mark the positions of the microprint.One phone brand updates its anti-counterfeiting features every quarter, like giving the product a security patch.
