AI Technical Summary
Technical Problem
Existing secure documents, such as polymer-based cards and booklets, lack sufficient personalization and are vulnerable to counterfeiting and fraud, as they often feature common security elements that can be easily replicated.
Method used
A personalization process using a laser beam to modify the surface of secure documents, creating unique images by smoothing specific portions of the surface without blackening them, thereby increasing personalization and security.
Benefits of technology
The process enhances the uniqueness and security of secure documents, making them more resistant to fraud and counterfeiting while maintaining the efficiency of series production.

Abstract
The invention relates to a laser personalization method for a secure document comprising at least one personalization area including at least one frosted surface (14D). The personalization method is particular in that it includes the generation of at least one first image by applying a laser beam to said surface, the application of the laser beam modifying the appearance of said surface by smoothing certain portions (14L) of it without blackening them. A lenticular grating (R) is arranged opposite the personalization area, which contains interlaced images (20, 30).
