If you win the Powerball lottery can you keep your identity sealed from release to the public?

Depends on where you buy the ticket. A few states let you claim the prize and will keep your name private if you wish. Several other states will allow the winner to claim a prize through a trust. The trust effectively hides your identity by masking it through the trusts name. Unless your a real rockhead, and your name is Joe Smith and create the Joe Smith Trust. Some states (Virginia is one, for example) require that your name be released to the public. They also require you to have your picture taken for PR uses.
