AI Technical Summary
Existing methods for securing and authenticating objects with digital certificates face challenges, such as expired certificates making signed data unverifiable, high storage costs for expired certificates, and limitations in fitting electronic seals within 2D barcodes due to size constraints.
A method and device that utilize a fragile anti-copy mark embedded with information about the object and its signature, allowing verification even after certificate expiration, and a segmented 2D barcode structure to accommodate all data within the barcode without altering its dimensions, using physical unclonable functions and cyclic redundancy codes for secure data verification.
Enables the verification of data integrity and object authenticity even after certificate expiration, reduces storage needs, and ensures readable 2D barcodes by distributing data across multiple zones within the barcode.
