This year ICASSP 2021 is avatarized! The small digital mini-me is wandering in the conference hall looking for the poster room 🙂.

See you on session IFS-4 Surveillance, Biometrics and Security tonight @ 10:30pm CEST to discuss our work

"LOOKING THROUGH WALLS: INFERRING SCENES FROM VIDEO-SURVEILLANCE ENCRYPTED TRAFFIC"

Is you video surveillance system completely safe? Probably, not.

A man is walking along a corridor, monitored by a set of CCTV cameras spread all over the building. Cameras are transmitting the encrypted video sequences to a central control room so that, even if a possible malicious user sniffs the stream, he/she can not decode and visualize the information … are we sure?

In the paper “Looking Through Walls: Inferring Scenes from Video-Surveillance Encrypted Traffic”, we are investigating how much information can be estimated from an encrypted video stream by analyzing packet lengths. The work was carried on within a cross-department collaboration involving Daniele Mari, Samuele Giuliano Piazzetta, Sara Bordin, Luca Pajola, Sebastiano Verde, Simone Milani, Mauro Conti.

Check out the full paper or join us at ICASSP 2021 next week.
