【Abstract】Internet of Things (IoT) and cloud metadata have highly sensitive details and facts about data and objects; it usually holds confidential information about the data for which there are access restrictions. Hence, it forms the most abundant source of information about any digital object from which the actual data can be rebuilt or duplicated with the same level of originality. However, it appears to be an emerging threat vector in IoT and cloud environments. If a misfeasor acquires access to the metadata information, then there arises a security threat. This article proposes a novel method on a bifold layered blockchain network, referred to as MetaInfoChain, to enhance the integrity and access controllability of safe storage. By default, blockchain protects the data while a permissioned blockchain forms an access control layer over the core blockchain. The acquired instance, compute, and the unique credentials sign device metadata to enforce controllability and validated by minters and add it to the base layer of the MetaInfoChain. Subsequently, we propose a consensus attainment algorithm to build an unrefined block on a candidate block comprising metadata packages. Consequently, all the nodes receive an unrefined block replica, which can afford absolute integrity. The top layer of MetaInfoChain is sensible to generate tamper-resistant metadata by executing hybrid PoS-PoW tasks on the unrefined block, causing robust integrity. After accomplishing all the checks, it endorses the MetaInfoChain to append the block with 35% block time efficiency in the base layer with a 56% throughput hike.
