📌 Homomorphic Encryption Summary

Homomorphic encryption is a type of encryption that allows data to be processed and analysed while it remains encrypted. This means you can perform calculations or run programmes on the encrypted data without needing to decrypt it first. The results, once decrypted, match what you would get if you had performed the same operations on the original, unencrypted data.

🙋🏻‍♂️ Explain Homomorphic Encryption Simply

Imagine locking a letter in a box and giving it to someone. They can shake, weigh, or stack the box with others, but they cannot read the letter inside. Yet, you can still tell if the boxes together meet certain conditions, all without opening them. Homomorphic encryption lets computers do maths on numbers that are still locked away, keeping the original numbers secret.

📅 How Can it be used?

Homomorphic encryption can be used to let medical researchers analyse encrypted patient data without ever seeing the raw personal information.

🗺️ Real World Examples

A cloud computing company can process financial calculations for a bank using homomorphically encrypted data. The company never sees the sensitive financial details, but can still return correct calculation results to the bank.

A healthcare provider can send encrypted patient records to a research institute, which then analyses the data to find health trends while ensuring patient privacy is never compromised.

✅ FAQ

Homomorphic encryption is a way to keep data secure while still being able to work with it. It allows you to carry out calculations or run analyses on encrypted data, so you never have to reveal the original information. This is especially useful for sensitive data, such as medical records or financial details, where privacy is important but you still want to use the data for research or processing.

Yes, homomorphic encryption can help keep your personal information private when it is being processed by others. For example, if a company wants to analyse your data to provide a service, they can do so without ever seeing your actual details. This means your privacy is better protected, even when your data is being used.

Homomorphic encryption is still quite new and can be slow for big tasks, so it is not yet common in most everyday apps. However, it is being explored for use in cloud computing, healthcare and banking, where keeping information private is very important. As technology improves, it could become more widely used for protecting data in many areas.

💡Other Useful Knowledge Cards

SQL Injection

SQL Injection is a type of security vulnerability that occurs when an attacker is able to insert or manipulate SQL queries in a database via input fields in a website or application. This allows the attacker to access, modify, or delete data in the database, often without proper authorisation. SQL Injection can lead to serious data breaches, loss of sensitive information, and potential damage to an organisation's reputation.

Schema Evolution Strategies

Schema evolution strategies are planned methods for handling changes to the structure of data in databases or data formats over time. These strategies help ensure that as requirements change and new features are added, existing data remains accessible and usable. Good schema evolution strategies allow systems to adapt without losing or corrupting data, making future updates easier and safer.

Secure Enclave Encryption

Secure Enclave Encryption refers to a security technology that uses a dedicated hardware component to protect sensitive information, such as passwords or cryptographic keys. This hardware, often called a Secure Enclave, is isolated from the main processor, making it much harder for hackers or malware to access its contents. Devices like smartphones and computers use Secure Enclave Encryption to keep critical data safe, even if the main operating system is compromised.

Data Versioning Strategies

Data versioning strategies are methods for keeping track of changes to datasets over time. They allow users to save, access, and compare different versions of data, much like how software code is managed with version control. This helps ensure that past data is not lost, and makes it easier to reproduce results or roll back to earlier versions if needed.

Neural Activation Optimization

Neural Activation Optimization is a process in artificial intelligence where the patterns of activity in a neural network are adjusted to improve performance or achieve specific goals. This involves tweaking how the artificial neurons respond to inputs, helping the network learn better or produce more accurate outputs. It can be used to make models more efficient, interpret their behaviour, or guide them towards desired results.
