Start User Experience Expert Search
User experience expert witness candidates will typically provide expertise in intellectual property matters. Such matters may include a patent infringement case in district court or federal court, an Inter Partes Review (IPR) in the PTAB (where the only expert testimony is through a deposition), a trade secret dispute, or a patent case or proceeding in the International Trade Commission (ITC). Litigation support by a user experience subject matter expert could include opinion testimony, expert report, expert opinion, and expert witness testimony at trial. In a high-profile case, or litigation involving a significant financial stake, a law firm may request a testifying expert with prior expert witness testimony experience. In addition, clients may seek a qualified expert for pre-litigation consultant work.

This biometric data expert holds a PhD and thoroughly understands biometric data capture, processing, and privacy-preserving authentication and surveillance.
This expert has worked on privacy-preserving biometric-based authentication and surveillance, developed several prototypes, and published several papers. In particular, the authentication system obtains face data from the camera on a client-side computer or device, uses deep learning to process the data, extracts information from biometric data to encrypt a random secret, and allows an authentication server to store the encrypted secret. The server does not store the clear face image; instead, it stores the encrypted secret generated from the face. A user can authenticate through a client-side computer or device if keys extracted from the user's face, as captured by the camera, can properly decrypt the encrypted secret sent from the server.
