Increasing consumer experience and companies inner quality presents a direct demand of different requirements on supply chain traceability. Typically, existing solutions have separate data storages which eventually provide limited support when multiple individuals are included. Therefore, the block-chain-based methods are utilized to defeat these deficiencies by generating digital illustrations of real products to following several objects at the same time. Nevertheless, they actually cannot identify the change of products in manufacturing methods. The connection between components included in the production decreased, whereby the ability to follow a product’s origin reduced consequently. In this paper, a methodology is recommended which involves using a Block-chain in Supply Chain Traceability, to solve the issues of manipulations and changes in data and product source. The method aims to improve the product’s origin transparency. Block-chain technology produces a specific method of storing data into a ledger, which is raised on many end-devices such as servers or computers. Unlike centralized systems, the records of the present system are encrypted and make it difficult to be manipulated. Accordingly, this method manages the product’s traceability changes. The recommended system is performed for the cheese supply chain. The result were found to be significant in terms of increasing food security and distributors competition.
The existing Disaster Recovery(DR) system has a technique for integrity of the duplicated file to be used for recovery, but it could not be used if the file was changed. In this study, a duplicate file is generated as a block and managed as a block-chain. If the duplicate file is corrupted, the DR system will check the integrity of the duplicated file by referring to the block-chain and proceed with the recovery. The proposed technology is verified through recovery performance evaluation and scenarios.
