Securing Data that is Used by AI

Data poses significant challenges and risks for AI, especially in terms of security, performance, reliability, ethics, and trust.

Jan 25, 2024

Artificial intelligence (AI) is the science and engineering of creating machines and systems that can perform tasks that normally require human intelligence, such as perception, reasoning, learning, decision making, and natural language processing. AI relies on data for both training and inference, which are the processes of learning from data and applying the learned knowledge to new data, respectively. Data is the fuel that powers AI and enables it to achieve remarkable results in various domains and applications, such as healthcare, education, entertainment, security, and business.

However, data also poses significant challenges and risks for AI, especially in terms of security, performance, reliability, ethics, and trust. Data can be compromised, corrupted, or misused by malicious actors, leading to adverse consequences for AI and its users. Therefore, it is essential to secure data that is used by AI and ensure its quality, privacy, and integrity. In this article, we will provide some guidelines and best practices for securing data that is used by AI, covering the following aspects: data hygiene, data quality, and data privacy.

Data Hygiene

Data hygiene is the practice of maintaining the cleanliness and health of data that is used by AI. Data hygiene is important for AI security because it helps prevent data breaches, data loss, data misuse, and data degradation. Some examples of data hygiene practices are:

Collecting only the data types necessary to create the AI and deleting or anonymizing the data after use. This minimizes the exposure and retention of sensitive or personal data that may be exploited by hackers or unauthorized parties.
Encrypting and protecting the data from unauthorized access, modification, or leakage. This ensures the confidentiality and integrity of the data and prevents it from being stolen, altered, or leaked.
Logging and auditing all operations performed by AI and keeping a record of data provenance and lineage. This enables the traceability and accountability of the data and the AI and helps identify and resolve any issues or anomalies that may arise.

Data Quality

Data quality is the measure of how well the data meets the requirements and expectations of the AI and its users. Data quality is important for AI performance and reliability because it affects the accuracy, efficiency, robustness, and fairness of the AI outcomes. Some examples of data quality issues are:

Inaccurate, incomplete, or outdated data that may lead to erroneous or biased outcomes. For example, if the data contains errors, missing values, or outdated information, the AI may produce incorrect or misleading results.
Unfair, unrepresentative, or malicious data that may cause discrimination or adversarial attacks. For example, if the data is skewed, imbalanced, or manipulated, the AI may exhibit unfair or harmful behavior.

Some examples of data quality solutions are:

Validating, cleaning, and updating the data regularly. This improves the correctness, completeness, and timeliness of the data and reduces the noise and errors in the data.
Ensuring data diversity, fairness, and representativeness. This enhances the coverage, balance, and diversity of the data and reduces the bias and discrimination in the data.
Detecting and mitigating data poisoning, tampering, or spoofing. This protects the data from malicious interference or manipulation and prevents adversarial attacks on the data.

Data Privacy

Data privacy is the right and ability of individuals and groups to control how their data is collected, used, shared, and stored by AI and other parties. Data privacy is important for AI ethics and trust because it respects the dignity, autonomy, and consent of the data subjects and fosters the trust and confidence of the data users. Some examples of data privacy challenges are:

Identifying and complying with relevant data protection laws and regulations. For example, different countries and regions may have different rules and standards for data privacy, such as the General Data Protection Regulation (GDPR) in the European Union or the California Consumer Privacy Act (CCPA) in the United States.
Balancing the trade-off between data utility and data anonymization. For example, removing or masking the identifying information from the data may reduce the risk of privacy breaches, but it may also reduce the usefulness or quality of the data for AI purposes.
Protecting the privacy of individuals and groups whose data is used by AI. For example, the data may reveal sensitive or personal information about the data subjects, such as their identity, preferences, behavior, or health, which may expose them to discrimination, harassment, or harm.

Some examples of data privacy techniques are:

Using consent, transparency, and accountability mechanisms. For example, obtaining the informed and explicit consent of the data subjects before collecting and using their data, providing clear and accessible information about how the data is processed and protected, and being responsible and responsive for any data privacy issues or complaints.
Applying encryption, differential privacy, or federated learning methods. For example, encrypting the data to prevent unauthorized access or disclosure, adding random noise to the data to prevent individual identification or inference, or distributing the data across multiple devices or servers to prevent centralized storage or processing.
Enabling user control, access, and deletion of personal data. For example, allowing the data subjects to view, modify, or delete their data, or to opt out or withdraw their consent at any time.

Conclusion

Securing data that is used by AI is important and beneficial for both the AI and its users, as it enhances the security, performance, reliability, ethics, and trust of the AI outcomes. However, securing data that is used by AI is also challenging and complex, as it involves technical, legal, social, and ethical issues and trade-offs. Some future directions and research opportunities for improving AI security, such as:

Developing and adopting common standards and frameworks for data security and privacy across different domains and applications of AI.
Designing and implementing user-friendly and human-centric interfaces and tools for data security and privacy.
Educating and empowering the data subjects and users about their rights and responsibilities regarding data security and privacy.
