The winner of a $560 million Powerball jackpot — one of the largest prizes in United States history — can remain anonymous, a New Hampshire judge ruled Monday.

The woman who bought the winning ticket in January had gone to court to keep her name from being made public. Her lawyers argued that she feared being overwhelmed with requests for a share of her winnings and was concerned about her safety.

The state had argued that the names of lottery winners must be disclosed to ensure that prizes are distributed fairly and that winners are not related to lottery employees.

In the end, the court sided with the woman, saying disclosing her name would amount to an invasion of privacy.
