In recent years, the Internet of Things (IoT) has received considerable attentions and the overall number of connected devices in IoT is growing at an alarming rate. The end-terminals in IoT usually collect data and transmit them to the data-processing center. However, when the data involve user privacy, the data owners may prefer to encrypt their data for security consideration before transmitting them. This paper proposes a video deduplication scheme with privacy preservation by combining the techniques of data deduplication and cryptography. In the scheme, the data owner divides every frame of video into blocks of the same size. Then the blocks are encrypted and uploaded to the cloud platform. On the server side, identical blocks which have been already stored in the database are eliminated for saving the storage space.
