METHOD AND APPARATUS FOR GENERATING AND AUTHENTICATING SECURITY DOCUMENTS
First Claim
1. A method for generating a document for use with a personal identifier, personal data and an image, the method comprising:
- inputting the personal identifier into a processor;
inputting the personal text data into the processor;
inputting the image into the processor;
generating, by the processor, a first Message Authentication Code (MAC) based on the personal identifier;
generating, by the processor, a wave structure based on the MAC, the wave structure is defined as;
x′
y′
=f(x,y,a,b,c,d);
generating, by the processor, waved microtext based on the wave structure and the personal text data;
generating, by the processor, a letter screen image from the input image with the waved microtext; and
outputting the letter screen image.

Abstract
A method and system for generating a document for use with personal data and an image, including: inputting the personal text data into the processor; inputting the image into the processor; generating, by the processor, a personal identifier based on the personal text data, a first Message Authentication Code (MAC) based on the personal identifier; generating, by the processor, a first wave structure based on the MAC; generating, by the processor, waved microtext based on the wave structure and the personal text data; generating, by the processor, a letter screen image from the input image with the waved microtext; and outputting the letter screen image. A method and system for verification of the generated document is also disclosed.
