I/O 2023: What’s new in Android security and privacy

Android is built with multiple layers of security and privacy protections to help keep you, your devices, and your data safe. Most importantly, we are committed to transparency, so you can see your device safety status and know how your data is being used.

Android uses the best of Google’s AI and machine learning expertise to proactively protect you and help keep you out of harm’s way. We also empower you with tools that help you take control of your privacy.

I/O is a great moment to show how we bring these features and protections all together to help you stay safe from threats like phishing attacks and password theft, while remaining in charge of your personal data.

Safe Browsing: faster more intelligent protection

Android uses Safe Browsing to protect billions of users from web-based threats, like deceptive phishing sites. This happens in the Chrome default browser and also in Android WebView, when you open web content from apps.

Safe Browsing is getting a big upgrade with a new real-time API that helps ensure you’re warned about fast-emerging malicious sites. With the newest version of Safe Browsing, devices will do real-time blocklist checks for low reputation sites. Our internal analysis has found that a significant number of phishing sites only exist for less than ten minutes to try and stay ahead of block-lists. With this real-time detection, we expect we’ll be able to block an additional 25 percent of phishing attempts every month in Chrome and Android1.

Safe Browsing isn’t just getting faster at warning users. We’ve also been building in more intelligence, leveraging Google’s advances in AI. Last year, Chrome browser on Android and desktop started utilizing a new image-based phishing detection machine learning model to visually inspect fake sites that try to pass themselves off as legitimate log-in pages. By leveraging a TensorFlow Lite model, we’re able to find 3x more2 phishing sites compared to previous machine learning models and help warn you before you get tricked into signing in. This year, we're expanding the coverage of the model to detect hundreds of more phishing campaigns and leverage new ML technologies.

This is just one example of how we use our AI expertise to keep your data safe. Last year, Android used AI to protect users from 100 billion suspected spam messages and calls.3

Passkeys helps move users beyond passwords

For many, passwords are the primary protection for their online life. In reality, they are frustrating to create, remember and are easily hacked. But hackers can’t phish a password that doesn’t exist. Which is why we are excited to share another major step forward in our passwordless journey: Passkeys.

Passkeys combine the advanced security of 2-Step Verification with the convenience of simply unlocking your device — so signing in is as easy as glancing at your phone or scanning your fingerprint. And because they use cutting-edge cryptography to create a “key” that is unique between you and a specific app or website, passkeys can’t be stolen by hackers the way that passwords can.

Last week, we announced you can use a passkey to log in to your Google Account on all major platforms. We’re the first major tech company to simplify sign-in with passkeys across our own platform. You can also use passkeys on services like PayPal, Shopify, and Docusign, with many more on the way. Start saying goodbye to passwords and try it today.

To help support developers as they incorporate passkeys, we’ve launched a Credential Manager Jetpack API that brings together multiple sign-in methods, such as passkeys, passwords and federated sign in, into a unified interface for users and a single API for developers.

Better protections for apps

Accessibility services are helpful for people with disabilities but their broad powers can be used by malware and bad apps to read screen content. In Android 14, we’re introducing a new API that lets developers limit accessibility services from interacting with their apps. Now, with a new app attribute, developers can limit access to only apps that have declared and have been validated by Google Play Protect as accessibility tools. This adds more protection from side-loaded apps that may get installed and are trying to access sensitive data.

In Android 14, we’re preventing apps that target an SDK level lower than 23 from being installed. This is because malware often targets older levels to get around newer security and privacy protections. This won’t affect existing apps on your device, but new installs will have to meet this requirement.

More transparency around how your data is used

We launched the Data safety section in Google Play last year to help you see how developers collect, share, and protect user data. Every day, millions of users use the Data Safety section information to evaluate an app’s safety before installing it.

In Android 14, we’re extending this transparency to permission dialogs, starting with location data usage. So every time an app asks for permission to use location data, you’ll be able to see right away if the app shares the location data with third parties.

And if an app changes its data sharing practices, for example, to start using it for ads purposes, we’ll notify you through a new monthly notification. As with the permissions dialogs, we’re starting with location data but will be expanding to other permission types in future releases.

We’re also empowering you with greater clarity and control over your account data by making it easier to delete accounts that you’ve created in apps. Developers will soon need to provide ways for you to ask for your account and data to be deleted via the app and the app’s Data safety section in Google Play, giving you more control both inside and outside of apps. They can also offer you an option to clean up your account and ask for other data, like activity history or images, to be deleted instead of your entire account.

Better control and protection over your photos and videos

Last year, we announced the Android Photo Picker, a new tool that apps can use to request access to specific photos and videos instead of requesting permission to a users' entire media library. We’re updating Photo Picker through Google Play services to support older devices going back to Android 4.4.

With Android 14, we modified the photo/video permissions to let you choose only specific media to share, even if an app hasn’t opted into Photo Picker. You can still decide to allow or deny all access to photos but this provides more granular control.

We’re also introducing a new API that will enable developers to recognize screenshots without requiring them to get access to your photos. This helps limit media access for developers while still providing them with the tools they need to detect screenshots in their apps.

Android remains committed to protecting users by combining advanced security and AI with thoughtful privacy controls and transparency to protect billions of users around the world. Stay tuned for more upcoming protections we’ll be launching throughout the year and learn more about how Android keeps you safe at android.com/safety.
