Abstract

In this paper we study the robust dual watermarking algorithm in financial fraud detection. We propose a novel dual watermarking algorithm to protect the financial note from unauthorized tampering. First, the target watermark image is converted to binary format. We adopt the reversible and visible watermark to protect private information. Second, the secret key is generated from chaotic Tent map. We use the chaotic encryption to further protect the invisible watermark. Experimental results show that the proposed dual watermark encryption method is effective for financial note authentication. It may prevent potential financial fraud and improve information security.
