Lottery bosses have warned they will take action against people who try to con them out of a massive £33 million jackpot as mystery continues to surround the golden ticket.
Camelot said it was considering each claim on a "case-by-case basis" after confirming the winning ticket was bought in Worcester.
But the lottery operator warned it would act if it believed someone had "intentionally attempted to defraud the National Lottery".
According to CPS sentencing guidelines, fraud by false representation can be punished by a maximum term of ten years jail.
Susanne Hinte has claimed she won the £33 million jackpot with a ticket she put through the wash
A Camelot spokeswoman said: "With prizes of this size, it's perfectly normal to receive lots of claims from people who genuinely think that they may have mislaid or thrown away what they believe was the winning ticket.
"That's what we're seeing now - and we are looking into all of these claims as part of our efforts to find the rightful ticket-holder.
"However, if we believe that somebody has intentionally attempted to defraud the National Lottery, then, just like any other company, we reserve the right to take whatever action we consider is appropriate."
Camelot would not however, comment on what, if any action they had taken against attempts to defraud it.
John Plimmer, a former detective at West Midlands Police, said anyone caught making a fraudulent claim could face jail.
He told the Mirror: "If there is evidence someone deliberately tried to con Camelot to get their hands on £33 million then obviously that's a crime.
"They wouldn't have to successfully claim the money to be found guilty. Anyone convicted could be looking at a heavy custodial sentence."
In August 2012 shop keeper Farrakh Nizzar was jailed for 30 months after trying to claim a winning £1 million lottery ticket belonging to a pensioner couple. Camelot became suspicious of Nizzar when he couldn't answer basic questions about the ticket so checked CCTV footage where his scam was uncovered.
Hinte, 48, from Worcester, reportedly made contact with Camelot advisers on Friday, claiming her winning ticket no longer had a readable date or barcode.
Under the terms of its licence, Camelot has discretion to pay prizes in respect of stolen, lost or destroyed tickets if a player has submitted a claim in writing within 30 days of the draw.
Camelot has said that even if a winner with a stolen, lost or damaged ticket is identified, the money will not be paid out for at least 180 days so others can get in touch. If the Worcester prize goes unclaimed after a deadline of July 7, the money will be donated to good causes, the lottery operator added.
Camelot said it had not released details of the shop where the winning ticket was bought and no retailer had been informed that they sold the winning ticket.
A spokeswoman said: "We would only release details of the shop if we received a valid claim and the ticket-holder subsequently took publicity. We still would urge all players to check their tickets and contact us if they think they have the winning one."
Married couple David and Carol Martin, both 54, from Hawick in the Scottish Borders, won the other half of the £66 million jackpot, the UK's biggest Lotto prize.
Meanwhile, On Wednesday a friend of Hinte's told The Sun that she hadn't "believed" her story from "day one".
The woman, who the newspaper did not name, said: "I don't think the ticket is genuine. When I saw it I knew that it wasn't right."
She added: "I think she bought a later ticket after the day she says she had."
The Sun also revealed that Hinte had previously tried to falsely claim a £200 prize on a scratchcard she said had been damaged after she dropped it in a puddle - only two of the three required £200 symbols were visible.
