abstract: The electric network frequency (ENF) signal
can be embedded in multimedia recordings created in areas of electrical
activities. Recent work has used the ENF signal for such applications as
time stamp authentication and forgery detection. It is more challenging
to extract ENF signals from video recordings than from audio recordings
because of the low temporal sampling rate or frame rate of video
cameras. The rolling shutter of CMOS image sensor can be exploited as it
exposes a frame line by line, and the effective ENF sampling rate by
treating each line as a signal sample can be increased. This scheme was
shown to work well with static videos. This paper conducts a further
study on the exploitation of the rolling shutter for extracting ENF
traces from videos. The rolling shutter mechanism is modeled and
analyzed using multirate signal processing theory. Challenging cases of
videos with motions are examined, and solutions to extracting ENF from
them are explored.
