Security And Preservation For Video Data Transmission Using Blockchain Technology For Cloud Storage On Internet Of Things (Iot)

Abstract

In Internet of Things (IoT) process, the video transmission handles a security issue in larger extend. Forgery,
data theft are some of the issue that should be severely prone the IoT technology. Prior to data storage
mechanism, the data is sustained by means of centralized server. In most of the practical situation,
encrypted image has to be compressed in order to efficiently secure the data. So that, a pair of image
compression and encryption algorithms are designed to perform the operation. In this article, an effective
encryption-then-compression (ETC) scheme is designed where they considered both lossy and lossless
compression. This approach is driven in the prediction error domain and is reasonably very effective to
build high security level. Once the server is influenced by malicious attack, this threatened the security
problem in IoT. To outlook the aforesaid security issue, a block-chain based sensingvideo of transmission
and storage mechanism is proposed. Initially, the video information is sensed intelligently and splits them
intoindividual blocks. Next, the separated data blocks are encrypted by using intelligent encryption
algorithm and then securelytransmitted it. Lastly, the intelligent verification technique is used to confirm
the signature verification. This IoT based block- chain is highly reliable, less expensive and effective secure
informative data storage when compared to centralized storage mechanism and traditional IoT data
transmission.
