So I'd like to create some honeypot credit card data.
Creating the credit card numbers is easy (maybe). I can just create numeric integer values in a certain range. If I'm ambitious, I might try to create Luhn valid numbers, though I probably don't want to go that far. In fact, I'd kind of prefer to create known invalid numbers, which would be a useful technique. Anyway, as a bare minimum I'll just create some random integers.
Sec code can just be random. Expiration dates can be within certain ranges, random.
The hard part is: How can I create random names? I can't really use existing names, for obvious privacy reasons, even if I were randomly recombining first and last names (John Smith, Jane Doe, Bob Jenkins => John Jenkins, Bob Doe, Jane Jenkins) unless perhaps they're especially generic, I probably won't mind if I create some John Smith names in the random data.
But what can I use to seed the data that is non-harmful?
Have you taken a look at the Fake Name Generator? They have an API, and it will generate your CC info as well.
