Towards decentralized data storage in general cloud platform for meta-products

Meta products, such as wearable sensor devices, smart phones, and smart cars can offer intelligent services to users in the context of their daily lives and help them better themselves, and be more effective and efficient in achieving their goals. In order to personalize and contextualize their services better, Meta products need to store, reuse and combine user data. In present day's Meta products market, manufacturers typically have their own cloud based platforms used by the products for which they have been developed. Other products cannot use the data. Sharing user data is hampered by trust and privacy concerns. In this paper, we propose a decentralized storage with blockchain in a common cloud based platform that is applicable to every type of Meta Products and ensures trust and privacy for sharing user data across applications developed by different manufacturers.
