Don’t Use Your Middle Initial. So many people make the mistake of using their middle initial in everyday life without realizing the impact to privacy. If your name is John Larry Smith, using your middle initial makes it much easier for database operators to connect records. While there are many John Smiths out there, there are not nearly as many John L. Smiths. In most cases, you can get away with removing your middle initial from your driver’s license, checks and most legal documents.
