Abstract

In this presentation, I will describe the motivating scenarios and applications for blind-passive media forensics (BPMF) technologies, contrasting them with conventional solutions that require adoption of end-to-end protocols or embedding of watermarks. BPMF methods verify the authenticity of the received content at the point of use by checking the integrity of features characteristic of the natural scenes or capturing devices, or the anomalies caused by the tampering operations. I will review the significant results achieved so far and discuss the direction for future research.
