As a security technology, holography has many advantages.
1. It takes a lot of time and money to produce source holographic products, but mass copying is relatively cheap.
2. The equipment and technology necessary for mass production of holographic products in the early days were difficult to obtain.
3. Holographic products and printed trademarks seem to be quite different.
4. The tools traditionally used by counterfeiters for counterfeiting have no effect on holography.
Effective anti-counterfeiting security products should spend more time on reverse engineering (counterfeiting) than on creation. It will be accompanied by an automatic and effective certification process, which is used to update the design of the security label or trademark over a period of time. This period of time is very short compared to reverse engineering.
There are some good technologies in the field of data encryption. Through these technologies, information can be distributed in an encrypted form, and the information can be decoded through a key. Although the information is easy to read, the method of encrypting information is realized by a separate key that is kept secret. Therefore, it is very difficult to create a fake message that contains new information.
