“…Although, the model reduces the processing time and shows adequate performance, but the cloud usage might increase the system cost. In [41], another Ethereum based smart home solution was proposed that minimises the confidentiality, integrity and authentication issues of the IoT devices and centralised gateway issues, however, the proposed design has not addressed the addition computational complexity created by blockchain. The reader is referred to [42] for the description of smart contracts and their role in blockchain.…”

Smart Home automation is increasingly gaining popularity among current applications of Internet of Things (IoT) due to the convenience and facilities it provides to the home owners. Sensors are employed within the home appliances via wireless connectivity to be accessible remotely by home owners to operate these devices. With the exponential increase of smart home IoT devices in the marketplace such as door locks, light bulbs, power switches etc, numerous security concerns are arising due to limited storage and processing power of such devices, making these devices vulnerable to several attacks. Due to this reason, security implementations in the deployment of these devices has gained popularity among researchers as a critical research area. Moreover, the adoption of traditional security schemes has failed to address the unique security concerns associated with these devices. Blockchain, a decentralised database based on cryptographic techniques, is gaining enormous attention to assure security of IoT systems. The blockchain framework within an IoT system is a fascinating substitute to the traditional centralised models, which has some significant concerns in fulfilling the demand of smart homes security. In this article, we aim to examine the security of smart homes by instigating the adoption of blockchain and exploring some of the currently proposed smart home architectures using blockchain technology. To present our findings, we describe a simple secure smart home framework based on a refined version of blockchain called Consortium blockchain. We highlight the limitations and opportunities of adopting such an architecture. We further evaluate our model and conclude with the results by designing an experimental testbed using a few household IoT devices commonly available in the marketplace.

“…In a public blockchain, anyone can join the network, read the data in the blockchain, and deploy new transactions. Anyone can check the data and benefit from the system's integrity and transparency [14,15]. In a private blockchain, only authorized nodes can participate in the network and receive transactions.…”

“…A smart contract is a program that runs automatically according to the rules proposed by Szebo [17]. Buterin implemented the smart contract on Ethereum consisting of the program code, storage file, and account balance [15,18,19]. Anyone can create a contract by posting a transaction to a blockchain.…”

A dashcam is a device that records events around a vehicle [1]. According to Embrain Trend Monitor research that surveys the satisfaction of dashcam users [2], the number of people who feel the need for a dashcam in their car has been steadily increasing. Because a dashcam records the event history of a vehicle, its videos can be used as evidence in disputes arising from accidents, both involving and observed by the dashcam owner. If a dashcam acquires video of accidents involving nearby vehicles, that video can be used as a record of the accident. In South Korea, public institutions often make announcements to look for witnesses of accidents and wait for a report. People share videos for various reasons [1], such as publicizing the truth, solving unfair cases, helping others, and benefitting the public. However, Kim et al. pointed out that waiting for a report and uploading a shared video via the web can reveal personal information such as location information or a fabricated Abstract Today, many people use dashcams, and videos recorded on dashcams are often used as evidence of accident fault. People can upload videos of dashcam recordings with specific accident clips and share the videos with others who request them, by providing the time or location of an accident. However, dashcam videos are erased when the dashcam memory is full, so periodic backup is necessary for video sharing. It is inconvenient for dashcam owners to search for and transmit a requested video clip from backup videos. In addition, anonymity is not ensured, which may reduce location privacy by exposing the video owner's location. To solve this problem, we propose a video sharing scheme with accident detection using deep learning coupled with automatic transfer to the cloud; we also propose ensuring data and operational integrity along with location privacy by using blockchain smart contracts. Furthermore, our proposed system uses proxy re-encryption to enhance the confidentiality of a shared video. Our experiments show that our proposed automatic video sharing system is cost-effective enough to be acceptable for deployment.

“…Moreover, the use of a backup server, which communicates with the storage server, is a classic solution. There are, many other solutions that use the token [14][15][16], also named the USB key, these solutions are effective but require a periodic update of the token with cloud providers; or those based on the blockchain that guarantees the security and integrity of data inside and outside smart homes [17]. Note also, that currently many systems based on Artificial Intelligence (AI) for the protection of privacy are widely used in many fields [18], such as secure communication, a social network, data mining, etc.…”

The National Institute of Standards and Technology (NIST) defines the fundamental of cloud computing as a concept for delivering a shared pool of configurable computing resources, which can be provisioned and released with minimum management effort and service provider interaction. Also, it enables convenient, on-demand network access to these resources [1]. Most companies today are increasingly interested in taking advantage of the flexibility and choice of multiple cloud offerings and adopt more than one cloud to make the best use of a variety of services [2]. Multi-cloud is a combination of multiple public clouds and private clouds [3]. Its goal is to enable cloud users to avoid vendor blocking and make the best use of multiple cloud services that can cooperate and interact with each other [4]. In 2018, the International Data Corporation predicted that more than 85% of IT companies would invest
