It ​allows for efficient computation and ⁤is commonly used in ​scenarios where the​ data‍ owner needs to protect‌ data from unauthorized access while⁤ allowing authorized parties to access it.
    1. Asymmetric Cryptography: Also known as⁣ public-key cryptography, this approach employs a pair of keys: a public key for encryption and a private key for decryption. It ensures secure communication ⁣between two parties without the need to exchange a shared ​secret key‌ in advance.

Privacy-Preserving AI with‍ Cryptography

Cryptography and AI Privacy

Cryptography enables the development of privacy-preserving AI systems⁤ in several ways:

1. ⁣Secure Data Sharing:

By encrypting data before sharing it with ​external entities, privacy risks⁤ associated ⁤with data breaches and unauthorized access are⁢ significantly mitigated. Encrypted ‌data can only be decrypted with the appropriate decryption key, ensuring that only authorized parties can access and utilize it.

2. Homomorphic Encryption:

Homomorphic⁤ encryption ‌allows computations to be ⁤performed on encrypted data, eliminating the need to decrypt data before processing it. This enables ⁤AI models to work directly ​on encrypted data while ⁤preserving privacy. The ‍output ⁤of the computations​ remains encrypted, ensuring sensitive information is never exposed.

3. Differential Privacy:

In differential privacy, noise is injected into the dataset, ⁣making it challenging to identify individual records while still⁤ allowing accurate aggregate analysis. Cryptographic techniques, such as​ adding random noise to query responses, offer ‌a robust method of achieving differential ⁣privacy and thus protect individuals’​ data.


Cryptography, as a ⁤critical component​ of‌ privacy-preserving technologies, has a pivotal role in ensuring the protection ‍of sensitive information in AI systems.​ Through various cryptographic techniques, such as secure data sharing, homomorphic encryption,‍ and differential privacy, privacy⁢ concerns can be addressed without⁣ sacrificing⁤ the benefits of AI.
