Covert Security Holograms
Covert security holograms contain hidden authentication features invisible to casual observation, requiring specialised tools or techniques for verification. These sophisticated security elements provide additional protection layers beyond overt holographic effects, enabling expert authentication while maintaining aesthetic appeal. Covert features remain completely hidden until activated by specific viewing conditions or detection equipment.
Multiple covert technologies can layer within a single hologram, creating a cascade of authentication levels for different user groups from field inspectors to forensic laboratories.
