Google has made a small change to Play Store apps that could prove a significant help to the security of your Android phone. The company is now adding a “small amount” of security metadata to Android APKs to be sure that they were distributed through the Play Store or an approved channel. This will make it possible to verify an app even you’re offline, Google said, making it possible to officially add that title to your store library and receive updates through Goole’s portal. It’s digital rights management by another name, as Android Central observed, but that doesn’t necessarily mean there’s reason to panic — it may ultimately be helpful, even if there are legitimate concerns.
