In our digital world, access to personal and public data has become an item
of concern, with challenging security and privacy aspects. Modern information
systems are heterogeneous in nature and have an inherent security
vulnerability, which is susceptible to data interception and data modification
due to unsecured communication data pipelines between connected endpoints. This
re-search article presents a blockchain-based model for securing data pipelines
in a heterogeneous information system using an integrated multi-hazard early
warning system (MHEWS) as a case study. The proposed model utilizes the
inherent security features of blockchain technology to address the security and
privacy concerns that arise in data pipelines. The model is designed to ensure
data integrity, confidentiality, and authenticity in a decentralized manner.
The model is evaluated in a hybrid environment using a prototype implementation
and simulation experiments with outcomes that demonstrate advantages over
traditional approaches for a tamper-proof and immutable data pipeline for data
authenticity and integrity using a confidential ledger.

提出了一种基于区块链的模型来保护异构信息系统中的数据通道，使用综合多灾害预警系统（MHEWS）作为案例研究，以解决数据通道中存在的安全和隐私问题，该模型利用区块链技术的固有安全特性，以分散方式确保数据的完整性、保密性和真实性，并在混合环境中进行评估，通过原型实现和模拟实验展示了相对传统方法更具防篡改和不可变性的数据通道，以实现数据的真实性和完整性，并使用机密账本。
