  Entanglement lies at the heart of quantum mechanics, and has been identified
an essential resource for diverse applications in quantum information. If
entanglement could be verified without any trust in the devices of observers,
i.e., in a device-independent (DI) way, then unconditional security can be
guaranteed for various quantum information tasks. In this work, we propose an
experimental-friendly DI protocol to certify the presence of entanglement,
based on Einstein-Podolsky-Rosen (EPR) steering. We first establish the DI
verification framework, relying on the measurement-device-independent technique
and self-testing, and show it is able to verify all EPR-steerable states. In
the context of three-measurement settings as per party, it is found to be noise
robustness towards inefficient measurements and imperfect self-testing.
Finally, a four-photon experiment is implemented to device-independently verify
EPR-steering even for Bell local states. Our work paves the way for realistic
implementations of secure quantum information tasks.
