Book-Shaped Security Document Production with Chaotic Serial Number Assignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for producing identification, value, or security documents, such as passports, lack sufficient security against theft and forgery, as the serial numbers are pre-assigned and not personalized until the data page is glued to the passport book, making stolen 'empty' passport books potentially usable with only personal data needed to be filled in.
Innovation Solution
A method where a passport book and data page are provided to an issuing authority, with the data page individualized by retrieving unique person-specific and/or document-specific information from a central database during the printing process, applying it as a machine-readable security feature, and assigning serial numbers chaotically by a server for increased security and cost-effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If serial numbers are pre-assigned and pre-printed on data pages, then production efficiency is improved, but security against theft and forgery deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-printing placeholder text or generic information on data pages before personalization, allowing the physical production process to proceed efficiently while the critical security element (unique serial number combined with personal data) is added later through individualization at the issuing authority, thus resolving the contradiction between production efficiency and security
Solution Approach 2:
The patent extracts the critical security function of serial number assignment from the pre-production phase and relocates it to the individualization phase at the issuing authority. By separating the physical document production from the security-critical personalization step, the system maintains production efficiency while dramatically improving security against theft and forgery
2Ease of operation
If data pages are individualized by printing personal data and gluing to passport books, then document functionality is improved, but security vulnerabilities increase due to pre-assigned serial numbers
Solution Approach 1:
The patent introduces a communication connection with a server containing a central database as an intermediary between the issuing authority and the data page personalization process. This intermediary securely transmits unique serial numbers and personal data only during the individualization step, ensuring that stolen blank passport books remain useless while maintaining the functionality of the document issuance process
3Loss of information
If serial numbers are assigned consecutively, then document traceability is improved, but storage requirements and manual errors increase
Solution Approach 1:
The patent replaces the manual mechanical system of consecutive serial number assignment with an automated computer-based system that retrieves serial numbers from a central database via communication connection. This substitution eliminates manual errors in assignment while maintaining full traceability through unique serial numbers, and reduces storage requirements by allowing efficient database management and reassignment of freed serial numbers

AI summary
The invention relates to a method for producing a book-shaped identification, value or security document (100), wherein a passport book (102) comprising a cover and a passport book block and a data page (106) are provided to an issuing authority (104), wherein the data page (106) is initially free of personalized data and is subsequently individualized by the issuing authority (104) by printing and affixed to the passport book (102), wherein during the individualization of the data page (106) a unique person-specific and/or document-specific piece of information is retrieved from a central database (110) and subsequently also applied to the data page (106).
