AI and Privacy-Preserving Technologies: Cryptography
AI And Cryptography For Privacy Protection: In today’s digital age, the rapid advancements in Artificial Intelligence (AI) have brought both tremendous benefits and growing concerns about data privacy. With large-scale data collection and processing becoming a norm, it is
crucial to implement privacy-preserving technologies to safeguard sensitive information. Cryptography, the practice
of secure communication through encryption, has emerged as a key tool in protecting privacy while enabling the
utility of AI.
Cryptography involves encoding data in such a way that only intended recipients can decipher it, ensuring secure
transmission and storage. It plays a vital role in maintaining confidentiality, integrity, and authenticity of both
AI models and the data they rely on. By leveraging cryptographic techniques, organizations can strike a balance
between data accessibility and privacy, addressing concerns such as unauthorized access, data breaches, and data
Types of Cryptography in Privacy-Preserving AI
AI And Cryptography For Privacy Protection Encrypting data at rest and in transit is a fundamental approach to secure AI systems. Two primary types of
cryptography techniques employed in privacy-preserving AI are symmetric key encryption and public key encryption.
Symmetric Key Encryption
Symmetric key encryption, also known as secret key encryption, involves the use of a single key for both encryption
and decryption. This approach is well-suited for securing large data sets that are processed across distributed
systems. The sender and receiver share a secret key that ensures the confidentiality and integrity of the data
transmitted between them. However, challenges arise when distributing the shared key securely.
Public Key Encryption
Public key encryption, also referred to as asymmetric key encryption, employs a pair of mathematically related keys:
a private key and a public key. The private key is kept secret by the owner, while the public key is freely
distributed. When a sender wants to transmit data securely, they encrypt it using the recipient’s public key, and
only the intended recipient, with access to the corresponding private key, can decrypt the message. This approach
eliminates the need for secure key distribution, making it more scalable and flexible for AI systems.
