Bayer: Science For A Better Life - research - Forgery-proof information storage

Forgery-proof information storage

Genuine security

Secure storage: PAP cards for experiments in holographic exposure.

Quality assurance: Dr. Rainer Hagen examines a holographic data storage system.

Have you ever got angry after paying a lot of money for an "original" replacement part that turns out to be a fake? Or do you think that security at airports should be a lot quicker? Researchers at Bayer have now developed a new plastic for storing data which can help. The information is written into the polymer's molecular structure using laser light, ensuring exceptional data security.

Large storage capacity and high security

Photoaddressable polymers (PAPs) can be rewritten on as often as you like. The material is particularly interesting because of its large storage capacity and excellent security features. The data can withstand temperatures of up to 120 degrees Celsius and will last for years if kept at room temperature. Data are encoded on PAPs using a hologram to make them secure against forgery. And the only way to make the information visible again is by knowing the encoding conditions.
