The current record for the largest total prize (and largest prize per winning ticket) was established in 2016. California residents Marvin and Mae Acosta won over $327,000,000 each, playing Powerball. They split a $1,586,000,000 prize with three other winners in Tennessee and Florida.
California state law makes the names of all state lottery winners part of the public record. However, the Acostas waited for weeks before claiming their prize, to contact teams of attorneys that helped them prepare.
This allowed them to protect their personal information considerably. You won’t be able to keep the public from knowing your name if you win. However, you can certainly take measures to make yourself less vulnerable to scams.
