PRAGUE – Not even porn stars can hide from Big Brother. A new online app uses facial recognition technology to identify adult performers.

PornstarID launched in public beta on Sept. 15. Currently, the site claims to be able to identify 596 models based on the 218,000 images developers used to “train” the software. Allie Haze, Romi Rain, Adriana Chechik, Jennifer White, Jessa Rhodes, Keisha Grey, Nikki Benz, Lexi Lowe, Riley Reid, Silvia Saint and Sunny Leone are among the familiar faces the app recognizes now.

“PornstarID uses a deep neural network to represent or embed the face on a 128-dimensional unit hypersphere,” according to a spokesperson. “The embedding is a generic representation for anybody’s face.”

Developers said they expect the app to identify 20,000 performers reliably by the time it exits beta-testing. Hopefully, it will provide better matches than the ones it sometimes offers now. The image at the top of this page was created by running the photo in the center through the system twice. The woman on the left may be the performer in the center picture. The woman on the right clearly is not.

The software also misidentified male performer Seth Gamble as a woman.
