FONT PRINTING SYSTEM HAVING EMBEDDED SECURITY INFORMATION COMPRISING VARIABLE DATA PERIODIC LINE PATTERNS |
摘要 |
A method and system is provided for providing a variable data guilloché shaped pattern comprised of variable data differential line pattern fonts comprising decodable template symbols which are capable of being selectively assembled into a predetermined variable data code. The code representations are embedded in the guilloché pattern amongst a plurality of unvaried standard base patterns. The representation can be decoded with a digital scan capable of identifying the embedded patterns and communicated it to a user for verifying a document containing the code.
