Recovering tampered regions in encrypted video using POB number system

作者：

Highlights：

• Framework for recovery of tampered regions in the encrypted domain for videos has been proposed.

• To enable the lossless recovery, the original information is compacted using the properties of the POB number system.

• For detecting the tampered regions in the encrypted domain, spatial and temporal information of the video frames are used.
