Data poisoning is a cybersecurity threat that aims to compromise the accuracy of artificial intelligence (AI) and machine learning (ML) systems by purposefully altering the data that is used to train these models. Data poisoning is a serious risk to the security and dependability of AI applications since it can cause biased or erroneous results from AI systems. Although the idea of data poisoning is not new, its consequences are growing more serious as AI and ML technologies are integrated into more areas of society, such as healthcare, banking, security, and self-driving cars.
Attacks involving data poisoning can be classified according to the strategies used and the attacker’s level of expertise. Attacks can be classified as either black-box or white-box, depending on the attacker’s level of knowledge of the model’s internal workings and training parameters. Data poisoning techniques include availability assaults, targeted attacks, subpopulation attacks, and backdoor attacks. Each of these techniques aims to manipulate the AI model in a different way to accomplish malevolent goals.
Data poisoning attacks can be executed with surprisingly low-cost and easily available means. For example, studies have shown that a hostile actor may alter the datasets that generative AI systems use for as little as $60. In order to do this, it could be necessary to buy expired domains and fill them with fake data, which AI models might then scrape and add to their training datasets. Such attacks have the potential to manipulate and contaminate at least 0.01% of a dataset, which may not seem like much, but can be substantial enough to produce outputs from the AI that are noticeably distorted.
It is imperative to stop data poisoning assaults, particularly when more businesses and governmental institutions are depending on AI to provide basic services. Using high-speed verifiers, being watchful over the databases used to train AI models, and applying statistical techniques to identify data anomalies are examples of proactive steps. It is imperative to consistently observe the performance of the model in order to identify any sudden changes in accuracy that can point to a data poisoning attempt.
Data poisoning is becoming a more serious hazard to AI systems, which emphasizes the necessity for strong security protocols and moral considerations throughout the creation and application of AI technology. The possibility of damage from data poisoning assaults increases with the integration of AI into vital systems, so academics, developers, and policymakers must take proactive measures to address this issue.
