Several attack methods against large AI models

With the application and promotion of new technologies such as artificial intelligence and big data, large models have also become a popular technology. Of course, organizations and individuals will begin to use various technologies to attack them.

There are many types of attacks against models, among which several are often mentioned:

(1) Adversarial sample attack:

Adversarial sample attack is one of the most widely used machine learning attack methods. During the attack, the attacker generates adversarial samples by adding small perturbations to the original data samples (such as misclassification or prediction that can fool the model), and misleads the classifier output of the machine learning model while keeping the model function unchanged. .

(2) Data poisoning attack:

Data poisoning attack is to destroy or destroy the use of the model by adding erroneous or disturbing data to the training data.

Note: Adversarial sample attacks and data poisoning attacks are somewhat similar, but the focus is different.

(3) Model stealing attack:

This is a model reversal and stealing attack that uses black box detection to reconstruct the model or recover training data.

(4) Privacy leak attack:

Data is the core asset used to train the model. Attackers may illegally obtain this data from legitimate connections or malware, resulting in user privacy deprived. And use it to train your own machine learning model to leak the private information of the data set.

Of course, there are many security protection methods, and the following are just a few of them:

(1) Data enhancement

Data enhancement is a common data preprocessing method , which can increase the number and diversity of samples in the data set. This technology can help improve the robustness of the model, making it less susceptible to adversarial sample attacks.

(2) Adversarial training

Adversarial training is also a commonly used method to defend against adversarial sample attacks. It improves the model's resistance to attacks by allowing the model to learn how to resist adversarial sample attacks. Robustness allows the model to better adapt to adversarial examples.

(3) Model distillation

Model distillation technology can convert a complex model into a small model. Because small models are more tolerant of noise and disturbances.

(4) Model integration

Model integration uses multiple different models to make predictions, thereby reducing the risk of adversarial sample attacks.

(5) Data cleaning, filtering, and encryption

Cleaning, filtering, and encryption of data is also a common protection method.

(6) Model monitoring and auditing

Model monitoring and auditing is a method that can identify unusual behaviors in the training process and prediction tasks, thereby helping to detect and repair model vulnerabilities early.

Today, with the rapid development of technology, attackers will use various technical means to carry out attacks, and defenders need more technologies to improve security protection. Therefore, while ensuring data security, we need Continuously learn and adapt to new technologies and methods.
