Start-up Bitkoo is releasing as a commercial product identity-management technology developed and deployed by The Walt Disney Co. that it says provides cutting-edge authentication/authorization and auditing/compliance capabilities.

Bitkoo, however, isn’t just taking over commercial development of the technology that Disney calls Keystone. The start-up’s founder invented Keystone before leaving Disney.

Doron Grinstein, CEO of Bitkoo, brainstormed the idea and wrote the software for Keystone, which Disney has been using for nearly three years to protect access to many of its critical applications, such as the central reservation system at Walt Disney World in Orlando.

The Burton Group analyst firm last year called Keystone, “cutting edge” and featured a Disney presentation on Keystone at its annual Catalyst conference. The firm said Keystone’s ability to move authorization responsibilities away from applications “is one of the goals we have had as an industry for a number of years.”

Now the application, which handles nearly 10 million authorization requests per year at Disney, is available to the public.

Keystone provides a centralized engine that eliminates the need for authorization mechanisms to be built into applications. Applications and Web services written with tools such as Java, .Net, Delphi and COM need only a single line of code to turn their authorization duties over to Keystone.

Keystone’s access controls can be dialed down not only to secure individual applications but also to secure access to specific buttons, text boxes and functions within an application, as well as variables such as what times, from what IP address and under what conditions a user can access an application. In addition, auditing capabilities help organizations manage compliance requirements.

Disney, which is known for the quality of its homegrown technology, said late last year it was looking for someone to take Keystone commercial.

“I went to Disney and said the best place for Keystone is with its creator,” said Grinstein. “I have a great vision for it.”

That vision includes adding to Keystone 3.0, which Grinstein unveiled Tuesday at Interop, a new technology he has filed a patent for called “authlets.”

The authlet is a digitally signed piece of authorization data that can be as simple as where the user is located.
