Which principle is NOT a core privacy principle for financial institutions?

Maintaining complete transparency regarding all information sharing is not categorized as a core privacy principle specifically for financial institutions. The core principles outlined by regulations such as the Gramm-Leach-Bliley Act emphasize the importance of protecting consumer information and limiting data collection to what is necessary for legitimate business purposes. These principles focus on safeguarding private data and ensuring that institutions use the data solely for the intended purposes for which it was collected.

While transparency in information sharing is important and is often encouraged as a best practice within the broader context of privacy compliance, it does not distinctly stand out as a formal requirement or a core principle for financial institutions. On the other hand, the principles that focus directly on data protection, minimizing data collection, and using data appropriately are essential tenets that govern how financial institutions handle consumer information and are foundational to privacy compliance in this sector.
