Variogram® is a technology that combines serialization with holographic technology to produce a unique, serialized hologram. The Variogram ® consists of a static custom logo and a variable reference, both materialized as a hologram.
Variogram® is a perceptible security component customized to the customer’s image. The graphic design can be a logo or text.
The Variogram ® holographic variable reference uses a random security code.
Each Variogram is associated with a certificate hosted on the Prooftag Cerv.
Variogram® contains a random security code that is associated with a database record reference.
It is in this local database, cloud, blockchain… that the associated data is stored.
Variogram® is a serialized optically variable marking. The solution offers several options such as holographic pattern details and seal color (bright silver, bright gold, matte silver).
Each Variogram® has a unique variable holographic element such as a reference or 2D code. This holographic serialization provides a higher level of security than a conventional hologram. Variogram® can receive additional security:
A random security code that can be verified online – CCP
An encrypted 2D Code – CryptoMatrix™ or CryptoQRCode™
Variogram® Seals are constructed on a destructible metallized security film, an attempt to remove it will result in visual alteration.
These features reduce the risks associated with retrieving and repositioning the authenticating element.
These products are then used for brand protection and document security.
