Computing giantNvidiahas developed a new AI framework that it hopes will eventually replacepasswordsandmulti-factor authenticationas the most common way of securing digital identities in thehybrid workplace.
The framework, which will first become available on January 23, 2023 as part of end-to-end workflow application Nvidia LaunchPad, looks to build onthe company’s digital fingerprinting researchby using graphical processing units (GPUs) to train deep learning models on user habits.
These habits, such as typing speed, typo frequency, and “what services [users] use and how they use them”, are the next development inZero Trustnetwork environments, although Nvidia recognizes that cybersecurity is an “ever-evolving digital wall.”
Nvidia digital fingerprinting framework
Nvidia’s plan is to assign a deep learning model for “every account, server, application, and device on the network”, creating a ‘personality’ of sorts for each person or thing with a presence on a company network. IT staff assigned to monitor them can then tweak the models to send alerts for specific kinds of activity.
The Director of Cybersecurity Engineering and R&D at Nvidia, Bartley Richardson, recognises that the framework has a long way to go, given that, when he first pitched the idea to his technology leads in February 2022, he was told that the idea was “crazy” and “computationally impossible”. At the time, GPUs had no role in cybersecurity.
However Daniel Rohrer, Nvidia’s Vice President for Software Product Security, saidat a GTC talk in September 2022that a tech industry-wide lack of computational resources to train these models and store the data was fuelling Nvidia’s desire to combine cybersecurity and AI into one fingerprinting solution.

Fast forward to October 2022, and Nvidia had its AI-powered digital fingerprinting framework deployed across its global networks on fourNvidia A100 Tensor Core GPUs.

It claims that, with the framework in place, IT teams may have their workloads cut drastically, having to deal with only “8-10 [security] incidents to investigate daily”.
That’s a drastic reduction, and a robust defence against intrusions, when the2022 Verizon Data Breach Investigations Reportclaimed that 40% of all data compromises involved stolen credentials.
Following the Nvidia Launchpad trial, the company will make the AI framework available as part of the digital fingerprinting AI workflow inNvidia AI Enterprise 3.0.
But before then, and even before we know whether using AI to power digital fingerprinting is even feasible long-term, Jason Recla, Nvidia’s Senior Director of Information Security, has some advice for IT admins looking to help create a longstanding tech environment designed to support new, AI-driven solutions.
“Get up to speed on AI. Start investing in AI engineering and data science skills — that’s the biggest thing.”
