Privacy Enhancing Technologies (PETs) are a collection of instruments that can assist in optimizing the utilization of data by mitigating the risks associated with its use.

These innovative solutions reduce the risk of data exposure while facilitating the management, processing, and sharing of information.

Requirement for Technologies that Enhance Privacy

PETs are indispensable in the current environment, where concerns about data breaches, surveillance activities, and unauthorized data utilization are rampant. They not only ensure the Confidentiality, integrity, and accessibility of data but also empower individuals to take control of their data, instilling a sense of security and ownership.

By cultivating user trust and ensuring compliance with privacy regulations, PETs are a critical component in protecting online Privacy, empowering individuals to determine the use of their data.

Conventional data protection methods provide Strong security guarantees for data in transit and at rest. Encryption, access control, identity management, secure tunnels, firewalls, traffic monitoring, multi-factor authentication, and device management are among the current-generation practices that ensure data is protected and only accessible to its intended users.

However, these methods must address data protection in use, even though they all achieve their intended objective of safeguarding data in transit and at rest.

Data must typically be converted to its unprotected form, plaintext, in order to be exploitable. This rule applies to the utilization of data by both humans and machines.

The plaintext must be accessible and available in both scenarios. Regrettably, this creates an opportunity for unauthorized parties, such as hackers or unauthorized users, to access data, whether intentionally by malicious actors or inadvertently by negligent users.

As the landscape continues to evolve in response to the proliferation of real-world artificial intelligence (AI)-)-enabled systems are increasingly used in various industries for data analysis and decision-making, so resolving data-in-use concerns is more important than ever.

Traditional systems typically rely on explicit, pre-programmed instructions to execute tasks, whereas AI-enabled systems exclusively depend on data-in-use processes. All data in AI-enabled systems, including AI models, is involved in data-in-use processes, such as inference and training.

AI engineers are increasingly turning to privacy-enhancing technologies (PETs) as the next-generation safeguards for their systems to remain competitive in this changing landscape. This ensures that the audience is well-informed and prepared for the future of data privacy, instilling a sense of readiness and anticipation.

Confidentiality and Privacy

When administering sensitive data, one must consider two critical, high-level concepts: Privacy and Confidentiality.

1. Privacy is the capacity to regulate the extent, duration, and circumstances of sharing personal information. To maintain Privacy, precise measures for collecting, utilizing, retaining, disclosing, and eradicating personal information are imperative.
2. Confidentiality is the term used to describe safeguarding any information that an entity has disclosed in a relationship of trust with the expectation that it will not be disclosed to unintended parties.

The primary distinction between Privacy and Confidentiality is that the former pertains to personal information, whereas the latter pertains to sensitive data.

Furthermore, Confidentiality pertains to the unauthorized use of information that is already in an organization’s possession. On the other hand, Privacy pertains to the individual’s capacity to manage the information that an organization collects, utilizes, and shares with others.
