Online And Physical User Identities

Some data-owning businesses are getting into the Internet authentication market -- and that's good news

The desire to have a strong authentication mechanism that Internet businesses can use to authenticate their users is becoming more of a necessity than a pure desire. The growth of cybercrime is creating opportunities for the data that some businesses keep on individuals to become much more valuable.

When a user enters certain information in a Web form to conduct business, the website can consult with businesses that maintain information about individuals, such as credit bureaus, to make sure that the data provided is at least consistent. This type of service can protect against a large number of fraudulent uses of personal information where the cybercriminal has some information about the victim and tries to use it for financial gain. Higher levels of identity theft would not be affected if the criminal has a lot of information that is, in fact, consistent.

I think these types of services are very useful in detecting and preventing many of the forms of fraud we see today. We are observing that some of the data-owning businesses are getting into the Internet authentication market -- which adds a lot of value to all involved. I think the initial collaboration we are starting to see today among many companies, small and large, in this type of authentication will end up producing a much better business environment that we will feel comfortable to use for more transactions.
