Emily Eavis says other parts of the entertainment industry should follow Glastonbury's lead on tickets.
The festival's organiser is speaking to Newsbeat as the Government says it wants to make it easier for real fans to get hold of gig tickets for fair prices.
MPs have been told it's too easy for professional touts to operate.
And they've criticised secondary sites for not doing enough to check where the tickets are coming from.
Tickets for next year's Glastonbury sold out in less than an hour.
But for a decade now, the festival has tried to stop them being passed on.
"We have a registration system which is now in its 10th year," explains Emily Eavis.
"It involves people registering, uploading a photo and then that photo gets assigned to your ticket.
"That means people's tickets are protected and that's the most important thing."
The photo ID makes it hard to pass the ticket on.
"We've had years of hearing these terrible stories from people who've been ripped off or tickets not turning up because they've been bought on imaginary sites," she says.
"Our system works really well."
There's nothing illegal about putting a ticket on a secondary site for an inflated price - and it's often the only way of getting hold of one when an event has sold out.
But Emily Eavis doesn't want to get involved.
"We want to eliminate the 'for profit' secondary market when it comes to Glastonbury.
"And that's what this does. It means people are paying the right price for the ticket. We do our best to keep the price down. The last thing we want is people spending twice the amount on a ticket that's dodgy or unreliable."
Emily Eavis accepts that people who miss out on Glasto tickets would love the chance to get them from a secondary site - but she insists protecting the tickets outweighs the downsides.
"We would rather do this and make it safe for people to buy tickets than get involved in secondary sites," she says.
"We'd like others in the industry to adopt similar methods. We've tweaked it over the years and it's proven that it works."
