How NPUs protect your privacy

In the current era, an increasing number of smartphones and PC processors are incorporating NPUs for more intelligent functionalities. As we all know, the online world poses many security challenges, with hackers usually attempting to gain access to your phone. However, NPUs offer more than just smart capabilities – they serve as protective measures for you and your devices. This article is going to explore the topic, of how NPUs protect your privacy.

NPUs at a Glance

An NPU (Neural Processing Unit) is a microprocessor that is developed specifically for neural network Machine Learning and Artificial Intelligence. You can find NPUs on smartphone SoCs and/or on laptops and desktop processors.

Unlike regular CPUs or GPUs, NPUs are engineered to execute artificial intelligence (AI) tasks with unparalleled speed and efficiency. These tasks involve processing large volumes of data through complex operations like machine learning (ML) and deep learning (DL).

Imagine a tiny smart person living inside your phone. That’s essentially what an NPU is. This specialized chip handles the artificial intelligence (AI) tasks, freeing up your phone’s main processor for other duties. This includes complex calculations used for facial recognition, voice commands, and image processing – all in the blink of an eye.

Defining Privacy

In today’s digital age, every tap, swipe, and click generates a trail of data. From your face ID to your voice recordings, these bits and pieces of your life paint a detailed picture of who you are. Unfortunately, this treasure trove of information can be a target for hackers and malicious actors, putting your privacy and security at risk.

As we immerse ourselves in the digital era, our smartphones and computers have become huge stores of personal data. Privacy, a fundamental human right, faces constant threats in the form of cyber attacks, surveillance, and identity theft. Protecting our data has become paramount in ensuring a secure digital existence.

How NPUs Protect Your Privacy

NPUs play a pivotal role in preserving our privacy through on-device machine learning. Instead of dispatching sensitive data to the cloud for processing, NPUs empower smartphones and PCs to perform AI tasks locally. Unlike traditional processing methods that send your data to the cloud for analysis, NPUs enable “on-device” AI. This means that all the processing happens right on your phone, within the secure walls of its hardware.

This local processing ensures that our data never leaves our devices, granting us complete control. No more data journeys into the unknown, no more vulnerabilities exposed to online predators.

Examples of NPU-Powered Privacy Protection

  • Face Unlock: NPU can recognize your unique facial features instantly and unlock your phone. This is done on-device without ever exposing your biometric data to the cloud or internet.
  • Voice Assistant: Voice commands issued to the phone or laptop are understood and processed locally on your device. This removes the necessity to transmit them over the Internet to distant servers for processing and ensures the confidentiality of your conversations. As a bonus, it also prevents your voice from being captured and utilized for deep fakes.
  • Camera Enhancements: Photos and videos receive real-time enhancements without uploading images to the cloud.
  • Translation: Text or speech translation occurs on-device, bypassing the need for an internet connection.
  • Gaming Experience: Realistic graphics and adaptive gameplay occur without downloading additional data from the cloud.
  • Secure Payments: Facial recognition or fingerprint scans for online payments happen directly on your device, safeguarding your financial information.
  • Personalized Experiences: Suggestions for music, news, or even fitness routines are created using your usage patterns, ensuring your preferences remain private.

How to Get an NPU

NPUs are not sold separately, instead they are integrated into SoCs and PC processors. As a result, the device you buy determines the NPU that you’ll get. Popular SoCs and processors with NPUs include Qualcomm Snapdragon, Samsung Exynos, Apple, Huawei Kirin, and Intel. Each NPU variation caters to different devices, enhancing privacy and on-device machine learning capabilities.

The Future of Privacy is on Chip

NPUs are still evolving, but their potential for safeguarding our digital lives is undeniable. As these chips become more powerful and efficient, on-device AI will become the norm, creating a more secure and private future for our interconnected world.


NPUs are not just fancy chips; they’re like guardians for our devices, making them smarter and keeping them safe. How NPUs protect your privacy is simple. NPUs use on-device machine learning to improve your smartphone experiences and protect your privacy from online threats. NPUs play a crucial role in the digital world, ensuring your data stays secure. So, when you appreciate your phone’s smart features, remember the NPU silently working to keep your digital life private. Dive deeper into NPUs by exploring this site further to gain more knowledge. Knowledge is power, especially for privacy, so keep learning and shaping a digital world where our secrets are as safe as our thoughts.
