Privacy-Preserving Technologies Poised for Exponential Growth in Upcoming Hockey-Stick Moment

Dr. Rand Hindi, CEO of homomorphic encryption startup Zama, delves into the importance of privacy in the realm of deep tech for the coming year. Deeptech startups, tackling critical global challenges such as climate change, longevity, semiconductors, and AI, have seen a surge in venture capital investments, constituting 20% of the total, according to a Boston Consulting Group report. Hindi defines deeptech as companies that invest significantly in research and development to solve complex scientific or engineering problems, typically requiring several years of development before unlocking substantial opportunities.

Hindi, with over a decade of involvement in cryptography and privacy-preserving technologies, predicts key trends in cryptography for 2024. First and foremost, there is a heightened awareness and demand for data privacy, driven by consumer consciousness of personal data value and vulnerability. Regulatory pressures, especially from laws like GDPR in Europe, contribute to the trend as businesses invest in privacy and security solutions to ensure compliance. Technological advancements, particularly in AI and big data, and the increasing sophistication of cybersecurity threats are additional factors accelerating investment in privacy-preserving technologies.

Investors are recognizing the long-term value of privacy tech, viewing it not only as an immediate need but as a strategic investment. Hindi notes that this shift in perception is reflected in increased investments toward sustainable, long-term outcomes in the privacy technology sector. He emphasizes the importance of privacy tech as a fundamental requirement for future technological advancements.

In 2023, Hindi observes a transformation in investor decision-making, particularly in the privacy technology sector. Investors are perceiving privacy technology as having long-term value and recognizing the critical need for technologies safeguarding against privacy breaches. A noticeable shift in consumer sentiment towards privacy is influencing investment decisions, with a growing demand for products and services that protect personal data.

As someone deeply embedded in the European deep tech ecosystem, Hindi highlights Europe's strong regulatory framework for data protection, positioning it at the forefront of the privacy tech industry. The collaborative spirit within the European deep tech ecosystem has fostered innovation, attracting investments in privacy tech.

Looking forward to 2024, Hindi anticipates rapid evolution in privacy technologies, driven by increasing digitalization and the need for robust data protection mechanisms. He identifies key technologies that will reshape privacy and data security:

Homomorphic Encryption (FHE):

FHE represents a groundbreaking advancement, allowing computations on encrypted data without decryption. It is expected to gain traction in blockchain, AI, and sensitive cloud applications.

Differential Privacy:

This approach enables computing aggregated statistics without revealing individual data points, making it useful for web and mobile analytics, government census, road traffic analysis, and pandemic tracking.

Federated Learning:

This machine learning approach allows model training on decentralized devices, crucial for privacy as it avoids sharing raw data. It is expected to gain prominence in areas like autonomous driving, smart manufacturing, and healthcare.

Zero-Knowledge Proofs (ZKPs):

ZKPs allow proving a statement's truth without revealing information beyond the statement itself. Widely used in blockchain applications, ZKPs will become indispensable for maintaining privacy and security.

In conclusion, Hindi emphasizes that privacy will continue to be a central focus in the deep tech space, with a need to balance the potential of AI and big data with the fundamental requirement to protect individual privacy. The investments made in 2023 are seen as just the beginning of a sustained and growing interest in privacy technology as an integral part of the digital future.
