Obfuscating Data in SQL Server

Dave Mason has a data obfuscator:

In a previous post, I explored an option for generating fake data in sql server using Machine Learning services and the R language. I’ve expanded on that by creating some stored procedures that can be used for both generating data sets of fake data, and for obfuscating existing SQL Server data with fake data.

The code is available in a Github repository. For now, it consists of ten stored procedures. 

Unlike something like Dynamic Data Masking, this is a permanent update to the table. That makes it quite helpful for getting production distributions and use cases into non-production environments.
