AI models and datasets are valuable assets that enable new possibilities and opportunities for innovation, efficiency, and productivity. However, they also pose new challenges and risks for security and privacy. Security and privacy of AI models and datasets are essential for preserving their functionality and performance, protecting their intellectual property rights, preventing their misuse or abuse, respecting the rights and interests of their data subjects and stakeholders, complying with their legal and ethical obligations of their data controllers, and ensuring their quality and validity. This can be achieved by applying various techniques that prevent unauthorized access, use, or disclosure of AI assets or personal or sensitive data, and detect and respond to any security or privacy incidents.

Security of AI Models and Datasets

Security of AI models and datasets refers to the protection of AI assets from unauthorized access, use, or disclosure. AI assets include the AI models themselves, the datasets used to train or test them, the algorithms or code that implements them, and the systems or devices that run them. The security of AI models and datasets is important for several reasons:

• Preserving the functionality and performance of AI models: Security of AI models and datasets helps to ensure that they function as intended and deliver the expected results. Security breaches can compromise the integrity or availability of AI models or datasets, leading to errors, failures, or disruptions in their operation.
• Protecting the intellectual property rights of AI developers: Security of AI models and datasets helps to safeguard the intellectual property rights of the developers or owners of AI assets. Security breaches can result in the theft or leakage of AI models or datasets, which can undermine their competitive advantage or cause economic losses.
• Preventing the misuse or abuse of AI models: Security of AI models and datasets helps to prevent the misuse or abuse of AI assets by unauthorized parties. Security breaches can enable attackers to access or manipulate AI models or datasets for malicious purposes, such as launching cyberattacks, conducting espionage, sabotaging systems, or influencing decisions.

Security threats to AI models and datasets can come from various sources, such as hackers, competitors, insiders, adversaries, or even the AI models themselves. Some common types of security attacks against AI models and datasets are:

• Data poisoning: Data poisoning is an attack that involves injecting malicious data into a dataset used to train or test an AI model. The goal is to corrupt the dataset and influence the behavior or output of the AI model. For example, an attacker can insert fake data into a dataset used to train a facial recognition system, causing it to misidentify faces. Another interesting example is patch-based adversarial attacks on self-learning models.
• Model stealing: Model stealing is an attack that involves extracting an AI model from a system or device that runs it. The goal is to obtain a copy of the AI model without authorization. For example, an attacker can use queries or inputs to infer the parameters or structure of an AI model hosted on a cloud service.
• Model inversion: Model inversion is an attack that involves reconstructing sensitive information from an AI model’s output. The goal is to infer private data that was used to train or test the AI model. For example, an attacker can use facial images generated by a face synthesis system to recover the original faces of the individuals whose data was used to train the system.
• Model evasion: Model evasion is an attack that involves crafting inputs that cause an AI model to produce incorrect outputs. The goal is to evade detection or classification by the AI model. For example, an attacker can add noise or perturbations to an image to fool a face recognition system into misclassifying it.
• Model tampering: Model tampering is an attack that involves modifying an AI model’s parameters or code. The goal is to alter the behavior or output of the AI model. For example, an attacker can change some weights or biases in a neural network to cause it to produce erroneous results.

To protect AI models and datasets from security attacks, various techniques can be applied, such as encryption, authentication, authorization, auditing, logging, monitoring, or anomaly detection. These techniques aim to prevent unauthorized access or use of AI assets or detect and respond to any security incidents.

Privacy of AI Models and Datasets

Privacy of AI models and datasets refers to the protection of personal or sensitive data that are collected, processed, or shared by AI applications or systems. Personal or sensitive data include any information that can identify or relate to an individual or a group, such as name, address, email, phone number, biometric data, health data, financial data, or behavioral data.

Privacy of AI models and datasets is important for several reasons:

• Respecting the rights and interests of data subjects: Privacy of AI models and datasets helps to respect the rights and interests of the individuals or groups whose data are used by AI applications or systems. Privacy breaches can violate the data subjects’ consent, control, access, or ownership over their data, or cause them harm or distress.
• Complying with the legal and ethical obligations of data controllers: Privacy of AI models and datasets helps to comply with the legal and ethical obligations of the entities that collect, process, or share personal or sensitive data. Privacy breaches can result in legal penalties, reputational damage, or loss of trust for the data controllers.
• Ensuring the quality and validity of AI models: Privacy of AI models and datasets helps to ensure the quality and validity of AI assets. Privacy breaches can compromise the accuracy, fairness, transparency, explainability, or accountability of AI models or datasets, leading to biased, unreliable, or unethical outcomes.

Privacy threats to AI models and datasets can come from various sources, such as hackers, competitors, insiders, adversaries, or even the AI models themselves. Some common types of privacy attacks against AI models and datasets are:

• Data breach: Data breach is an attack that involves accessing or disclosing personal or sensitive data without authorization. The goal is to obtain private information from a dataset used by an AI application or system. For example, an attacker can hack into a database that stores health records used by a medical diagnosis system, exposing the patients’ identities and conditions.
• Data inference: Data inference is an attack that involves deducing personal or sensitive information from an AI model’s output. The goal is to infer private data that was not explicitly revealed by the AI application or system. For example, an attacker can use facial expressions generated by an emotion recognition system to infer the emotional states of the individuals whose data was used to train the system.
• Data linkage: Data linkage is an attack that involves combining personal or sensitive data from different sources. The goal is to create a more complete profile of an individual or a group. For example, an attacker can link social media posts with location data to track the movements and activities of a person.
• Data de-anonymization: Data de-anonymization is an attack that involves re-identifying individuals or groups from anonymized or aggregated data. The goal is to break the privacy protection mechanisms applied to a dataset used by an AI application or system. For example, an attacker can use auxiliary information to re-identify individuals from a dataset that was anonymized by removing their names and other identifiers.
• Data poisoning: Data poisoning is an attack that involves injecting malicious data into a dataset used by an AI application or system. The goal is to corrupt the dataset and violate the privacy of the data subjects. For example, an attacker can insert fake or misleading data into a dataset used by a recommendation system, causing it to expose or manipulate the preferences or behaviors of the users.

To protect AI models and datasets from privacy attacks, various techniques can be applied, such as anonymization, pseudonymization, encryption, consent management, data minimization, or privacy by design². These techniques aim to prevent unauthorized access or disclosure of personal or sensitive data, or minimize the exposure or impact of such data.
