Polyolefin-Based Identification Documents (Awarded Jan 22, 2016)
Co-invented a tamper-resistant approach to securing passports and ID documents by encapsulating paper/textile inlays within durable polyolefin-based coatings and multi-layer “monobloc” structures. The design improves resistance to delamination, slicing, heat-based attacks, and weathering, and supports embedding secure elements like RFID/NFC and printed data—extending document lifespan while raising the bar against counterfeiting.
Document Authentication Using Distributed Ledger (EP3678872B1 | Priority: Sept 5, 2017; Published: Oct 26, 2022)
Co-invented a practical system to combat counterfeit “breeder documents” (e.g., birth certificates, diplomas, land titles) by attaching an RFIF sticker with chip that stores key document fields and a form-control number. The system generates a cryptographic hash tying the chip + document data together and records it on blockchain enabling fast authenticity checks (including via smartphone or authorized readers) and making tampering evident. Trademarked as dLOC™ and used in the City of Quezon - Philippines.
Laminate Structure for a Chip Card and Method for Card Production (2013)
Co-inventor of a technology that improves the structural durability of chip-enabled cards such as payment cards, identity cards, and electronic passports. The invention introduces a specialized adhesive laminate structure that securely bonds the chip module within the card body, preventing cracking and delamination caused by repeated bending and daily use. This innovation contributes to longer-lasting and more reliable smart cards used in payment systems, identity credentials, and secure government documents worldwide.
