Efficient Implementation of 2D Barcode Verification Algorithm for IoT Applications

This paper proposes a two-Dimensional Barcode-applied Verification Algorithm (2DBVA). The two-Dimensional Barcode (2DB) is used as an access tool for Internet-of-Things (IoT) applications. From a security aspect's point of view, 2DBVA has been evaluated in terms of security factors. To perform this evaluation, a Multiple-Layer Security Architecture (MLSA) has been used in order to attain the three security objectives which are: confidentiality, integrity, and availability. The 2DBVA aims to enable an authorized access to smart IoT applications such as smart city applications. The 2DBVA has adopted the 2DB to encrypt values being used as a smart-key. The performance of the proposed algorithm has considered a number of security factors in order to strengthen the security side of such an IoT application. To evaluate the 2DBVA accuracy, a total number of 166 2DBs has been generated. The proposed 2DBVA was implemented to securely encrypt and verify contents of 166 2DBs. Results have shown a high percentage of accuracy in terms of security for verified 2DBs used as smart keys for IoT applications.
