Ethical AI – How is AI Redefining the Insurance Industry?

By Antoine de Langlois, Responsible AI Data Scientist at Zelros

When Cybersecurity meets Artificial Intelligence, companies and organizations have many new challenges and potential threats to consider. Here are some examples of how AI can help combat a cyber-attack.

Adversarial attack

In the case of a Vision ML model, tasked to detect a panda, you can modify the input image to fool the algorithm into predicting a gibbon. While the image remains strictly identifiable as a panda for the human eye. It could fool an autonomous car into mis-identifying a stop sign with a speed limit road sign, with critical consequences. It can also be developed for speech recognition. Here again the sound change could not be detected by human ears but will fool the speech recognition device

To counter adversarial attacks, companies need to retrain the algorithm to ensure it detects and flags anomalies by proactively detecting the breaches and retraining the algorithm helps minimize such attacks. To have a robust model, companies can also “sample with noise” to help prevent a future adversarial attack.

Data Poisoning

Data poisoning happens when some samples of the data used for training the algorithm are manipulated to make it provide a malicious prediction triggered by specific inputs, while remaining accurate for all the other inputs.

This Data Poisoning manipulation is done before the model training step. Zelros has Ethical Report standard, collecting a dataset signature on the successive steps of modelization is precisely to check and prove afterwards the data has not been tampered with. This standard can be adapted by other companies as a best practice when using AI responsibly.

Privacy

When an individual or a group have very specific features within the dataset used to train an algorithm, their identity may be compromised. To avoid an individual identity to be revealed as part of the training data and thus a risk on their privacy, organizations can use specific techniques such as federated learning. It amounts to training individual models locally and federating them on a global level, to keep the personal data locally. As a general advice, detecting specific samples of outliers and excluding them from the training is also a good practice.

Bias Bounties

As for classical software, sharing details of an AI algorithm can become a liability if it is exploited with malicious intent, since it provides insights on the model structure. A countermeasure, evoked by Forrester as a trend for 2022 are bias bounties, which will help AI software companies strengthen their algorithm robustness.

“At least 5 large companies will introduce bias bounties in 2022.” – According to Forrester: North American Predictions 2022 Guide

Bias bounties are becoming a prime tool for ethical and responsible AI because they help ensure your algorithm is as unbiased and as accurate as possible, thanks to having more people review it.

Human Behavior

Before considering malicious activity to access our Data or manipulate the AI tool used, companies ought to pause and just consider the Personal Data we as people willingly (even if not knowingly) share. Our CyberSecurity main weakness is our proclivity to disseminate knowledge of our identity and activity. Artificial Intelligence or even basic data gathering tools have given this behavior consequences that may prove critical.

Let’s take an old example for reference, with the geo localization data openly shared on a social network:

https://www.nytimes.com/interactive/2018/12/10/business/location-data-privacy-apps.html

Although from 2018, it shows how individual scraps of data may be gathered to provide powerful insights on an individual Person identity and behavior.

These insights can then be leveraged by AI tools to categorize ‘potential customer targets’ and act on that intel. A more recent reference may be The Social Dilemma documentary about the world of the “attention economy” built on this Personal Data gathering. To limit the impact of our Human behavior, nothing beats culture and scientific awareness. Data Science acculturation is a key for more security on our private data but also for more fairness in AI models, as detailed in the first topic of this article.

“AI tools may be too powerful for our own good”: When provided data on customers, a Machine Learning model may learn much more than we would like it to. For example, even if the gender is not explicit in customer data, the algorithm can infer it through proxy features, when a Human could not (at least on that amount of data, in such a limited time).

For that aspect, analyzing and monitoring the ML model is crucial.

To better anticipate the algorithm/model behavior and prevent discrimination through proxies, a key element is diversity: Having multiple reviewers with complementary input through their individual cultural/ethical background. Organizations can also request algorithmic audits by Third parties, to take advantage of their expertise and workforce diversity if the team themselves lack diversity.
