| Summary: | Forgery can cause significant damage in terms of trust and authenticity. Therefore, it is essential that the integrity of important documents should be maintained to avoid implication of the document being jeopardized by criminals. In this study we explore the applicability of two-dimensional (2D) barcode, specifically Data Matrix Barcode, for the integrity verification of hardcopy documents. The proposed system also includes other cryptographic algorithms such as hashing (SHA-256) and timestamp. A tracking number that is unique for each document is added to enhance the document security protection. Based on modular implementation, the system modules can be simply plugged and played. The system was tested and experimentally proved that it is capable of providing reliable integrity verification for hardcopy document.
