The rapid digital transformation of financial services has reshaped the way individuals and organizations perform transactions, manage assets, and exchange sensitive information. The widespread adoption of digital banking, mobile payment platforms, cloud-based financial services, and financial technology (FinTech) has significantly improved accessibility and operational efficiency. However, these advancements have also increased the risk of cyber threats, including unauthorized access, data interception, financial fraud, identity theft, and information leakage. Conventional encryption techniques provide strong protection during data transmission but may reveal the existence of confidential information, making them attractive targets for cyber attackers. Steganography offers an additional layer of security by concealing sensitive information within digital media such as images, audio, or video, thereby reducing the likelihood of detection during communication. This chapter explores the significance of steganography as a secure communication mechanism for modern digital financial systems. It discusses the evolution of digital finance, emerging cybersecurity challenges, and the role of information hiding techniques in protecting confidential financial data. Furthermore, the chapter presents a comprehensive review of contemporary steganographic approaches, their applications in secure financial communication, electronic document protection, digital payment ecosystems, and confidential transaction exchange. A conceptual secure communication framework is also proposed to demonstrate how steganography can complement existing cybersecurity mechanisms within FinTech environments. Finally, the chapter highlights current limitations, implementation challenges, and future research opportunities associated with integrating steganography into next-generation digital financial infrastructures. The presented discussion provides researchers, practitioners, and policymakers with insights into adopting information hiding techniques for enhancing privacy, confidentiality, and trust in rapidly evolving digital financial ecosystems.
