There are two aspects to this question. We can secure a ticket. We and other companies have technology today that will make a ticket your own. It will not be transferable and that way you know that you own it until you want to transfer it yourself. It cannot be shared and it cannot be duplicated.
However, not every venue or promoter is willing to engage in that, because a ticket is inherently transferable. When you ticket, it's a bearer's certificate, so there is no law. If you try to enforce non-transferability or a controlled transferability, there is no law to support it. People could claim that you're not allowed to prevent transferability. We have to make up our minds as to whether we want to put technology in place to secure the ticket, including the laws that go with that, or leave it to the market to deal with it.
