Ensuring data integrity using blockchain technology

As 3D printing becomes an integral part of the manufacturing industries, there are new challenges that must be solved to promote mass adoption. In other words, how can you ensure the schematics were not tampered with in the midst of the transfer process? This is of paramount importance in mission critical systems. The very real threat of compromised blueprints causing mechanical failures is a problem the manufacturing industry faces regularly. At the time MOOG started this innovative journey, no reference or open source technologies existed that solved these complex issues in their entirety. Microsoft was able to partner with MOOG to help solve these real-world problems.

Utgivelsesdato Sammendrag A blockchain is a datastructure that is an append-only chain of blocks. Each block contains a set of transaction and has a cryptographic link back to its predecessor.

The cryptographic link serves to protect the integrity of the blockchain. A key property of blockchain systems is that it allows mu- tually distrusting entities to reach consensus over a unique order in which transactions are appended.

The most common usage of blockchains is in cryptocurrencies such as Bitcoin. In this thesis we use blockchain technology to design a scalable architec- ture for a storage system that can provide strong data integrity and ensure the permanent availability of the data. We study recent literature in blockchain and cryptography to identify the desired characteristics of such a system.

In comparison to similar systems, we are able to gain increased performance by designing ours around a permissioned blockchain, allowing only a predefined set of nodes to write to the ledger. A prototype of the system is built on top of existing open-source software. An experimental evaluation using different quorum sizes of the prototype is also presented.

Use of Blockchain for Ensuring Data Integrity in Cloud Databases

Companies with customer information and valuable intellectual property assets need to embrace a fool-proof and trustworthy technology rather than being purely applying defensive strategies using tools such as firewalls and intrusion detection systems. What all these businesses have in common is that we rely on each of them on an everyday basis and each of them carry and store a good chunk of our personal information. Blockchain is the culmination of decades of research and breakthroughs in cryptography and security, and it offers a totally different approach to storing information and performing functions, which makes it especially suitable for environments with high security requirements and mutually unknown actors. Blockchain is essentially a giant public ledger of information, meaning it can just as easily hold all of our personal information as well. The answer as to why blockchains are safer and more appropriate to hold our personal identifiable information PII lies in the nature of the technology itself. And, because blockchain gives individuals control over their own information, it is generally deemed to be more secure, reliable and trustworthy. The information stored on a blockchain is also immutable due to the multifarious node network design of blockchains as well as the cryptology governing it.

Optimizing Blockchain for data integrity in Cyber Physical Systems

And the expanding use of artificial intelligence AI has only increased that pressure. Here are three of the most common data integrity challenges organizations struggle with — see if any of these sound familiar to you:. If these are areas that your organization struggles with, there is good news — blockchain distributed ledger technology can help preserve data integrity and prove the trustworthiness of data-centric processes. Curious how? The agenda for the event is live, so take a look and reserve your spot at the event before it fills up. Twitter LinkedIn Facebook Email. Here are three of the most common data integrity challenges organizations struggle with — see if any of these sound familiar to you: Proving data provenance. There are many situations where companies have to demonstrate where they obtained data and identify who gave permission for them to have that data. Ascertaining data integrity. Is this the original data, or has it been tampered with?

Enterprise Cloud Security: Is Blockchain Technology the Missing Link?

Problems with data integrity aren't new. In fact, most sources credit an IBM programmer and instructor from the s with the famous acronym GIGO -- or garbage in, garbage out. Errors or even intentional manipulation of data have always plagued information systems. Even though modern systems may have better features for reducing errors, the very speed data gets generated today multiplies issues. Learn how a relatively new technology, blockchain, can help limit various threats to data integrity in this age of rapid data generation.

Six use cases for blockchain in security

Our CB Blockchain Seal solution ensures data integrity. If you care about auditability and compliance, read on. Companies now realize that blockchain is more than Bitcoin and other cryptocurrencies. A great example of this is using blockchain technology to secure documents and processes. Why is blockchain not a mainstream solution for data integrity yet? What problems are companies facing?

Blockchain technology, the core foundation of cryptocurrencies, is increasingly being used for other purposes and could solve the data integrity issue in collaborative CAD environments. However, it has some disadvantages such as the transparency of data and the slowness of storing data in the blockchain due to distributed consensus. Increasing demand by the Industry 4. This chapter explains how blockchain works, how can it be utilized in distributed CAD environments, what are the major challenges for implementation, and how CAD vendors could use it to increase CAD data integrity. The increasing complexity of modern engineering products requires new paradigms and leveraging any available technology to keep in pace with the competition.

Not a day goes by without a media report on how a particular firm or entity as well as an upcoming governmental initiatives is thinking of using Blockchain technology for security, integrity, and consistency of data. Further, anyone who has heard of Bitcoin would have definitely known that it is underpinned by the Blockchain technology and is perhaps the single most important reason for the latter becoming popular and vice versa. Thus, what is Blockchain and what are the benefits and challenges of using the same in applications, whether they are private data stores or publicly held and managed databases. To start with, Blockchain in the simplest sense is a Distributed Ledger or a Distributed Database wherein multiple instances of data records are held in several places that can be accessed only through Cryptographic codes. Before we discuss the last term in the last sentence, one might very well ask what is the Big Deal if multiple instances of the databases exist which is anyway the case with Distributed Systems. The answer to this question lies in how such databases can be accessed using a combination of a Private Key and Public Key both of whom are encrypted using Cryptographic means.

Data security is a major issue for smart home networks. Blockchain is a promising technology because of the distributed computing infrastructure network that makes it difficult for hackers to intrude into the systems through the use of cryptographic signatures and smart contracts. In this paper, an architecture for smart home networks that could guarantee data integrity, robust security, and the ability to protect the validity of the blockchain transactions has been investigated. Moreover, 15 hash functions were also examined and compared to understand the effects of each consensus algorithms on the data integrity verification check execution time and the time optimization provided by the proposed MMHT algorithm.
