📌 Blockchain for Data Provenance Summary
Blockchain for data provenance uses blockchain technology to record the history and origin of data. This allows every change, access, or movement of data to be tracked in a secure and tamper-resistant way. It helps organisations prove where their data came from, who handled it, and how it was used.
🙋🏻♂️ Explain Blockchain for Data Provenance Simply
Imagine a diary where each page is locked and no one can remove or change any entry. Every time something happens to your data, it is written in this diary so you can always check its entire history. Blockchain acts as this diary, making sure no one can erase or alter what happened to your data.
📅 How Can it be used?
A project could use blockchain to track and verify all changes made to sensitive research data in a collaborative environment.
🗺️ Real World Examples
A hospital uses blockchain to record every time a patient’s medical records are accessed or updated. This creates a permanent and auditable trail, ensuring doctors, nurses, and administrators can prove who accessed the data and when, helping protect patient privacy and comply with regulations.
A food supply chain company implements blockchain to track the journey of produce from farm to supermarket. Each step, from harvesting to transportation and storage, is recorded, so retailers and consumers can verify the origin and handling of the food they purchase.
✅ FAQ
What does using blockchain for data provenance actually mean?
Using blockchain for data provenance means keeping a reliable record of where data comes from, who has accessed it, and how it has changed over time. This is done in a way that makes it very difficult for anyone to tamper with the record. It helps organisations show that their data is trustworthy and that it has not been altered without permission.
How can blockchain help prove where data has been and who has used it?
Blockchain creates a secure, step-by-step log showing every time data is accessed or changed, along with who was involved. This means that if someone needs to check the history of a piece of data, they can see exactly what happened and when, making it much easier to prove its origin and usage.
Why is tracking data provenance important for organisations?
Tracking data provenance is important because it helps organisations ensure their data is accurate and reliable. It also makes it easier to meet legal requirements, protect sensitive information, and build trust with customers and partners by showing that data has been handled properly.

💡Other Useful Knowledge Cards
Auto-Retry
Auto-Retry is a feature in software systems that automatically tries to repeat a failed operation or request without needing manual intervention. This is often used when temporary issues, like network problems or a busy server, might cause a task to fail. By attempting the task again, the system increases the chance of success without bothering the user each time something goes wrong.
Prompt-Driven Microservices
Prompt-driven microservices are small, independent software services that use natural language prompts as their main way of receiving instructions. Instead of relying on strict programming interfaces or fixed commands, these microservices interpret and act on human-like requests. This approach makes it easier for users and other systems to interact with complex services by describing what they want in plain language. Prompt-driven microservices often use AI or language models to understand and process these prompts, allowing for more flexible and adaptable applications.
Autoencoder Architectures
Autoencoder architectures are a type of artificial neural network designed to learn efficient ways of compressing and reconstructing data. They consist of two main parts: an encoder that reduces the input data to a smaller representation, and a decoder that tries to reconstruct the original input from this smaller version. These networks are trained so that the output is as close as possible to the original input, allowing them to find important patterns and features in the data.
Responsible AI Governance
Responsible AI governance is the set of rules, processes, and oversight that organisations use to ensure artificial intelligence systems are developed and used safely, ethically, and legally. It covers everything from setting clear policies and assigning responsibilities to monitoring AI performance and handling risks. The goal is to make sure AI benefits people without causing harm or unfairness.
Virtual Private Network Tunneling
Virtual Private Network (VPN) tunneling is a method of securely sending information over the internet by creating a protected path, or tunnel, between your device and another network. This tunnel hides your data from others so that it cannot be easily read or intercepted. VPN tunneling is commonly used to keep online activities private and to allow safe access to remote networks, such as a companynulls internal systems from outside the office.
