The law of large numbers states that the observed random mean from an increasingly large number of observations of a random variable will always approach the distribution mean.
The Gramm-Leach-Bliley Act (GLBA), which is also known as the Financial Services Modernization Act of 1999, provides limited privacy protections against the sale of your private financial information. Additionally, the GLBA codifies protections against pretexting, the practice of obtaining personal information through false pretenses.
The Bureau of Consumer Protection recommends a number of practices to ensure the privacy of customer financial data and maintain GLBA compliance. These include running thorough background checks on all potential employees and giving access to sensitive data only to those that need it, when they need it.
