Google is working on a native fingerprint authentication solution for Android that would be embedded in all devices using the mobile operating system, according to tech media.Any app could plug into and use the planned fingerprint API, meaning users could authenticate Google Wallet or a Play Store purchase with a fingerprint.”Android M will include one-touch log-in for supported apps”, wrote Buzzfeed in a report, citing anonymous company sources.The search engine giant is expected to announce the feature next week during a keynote at Google I/O, the search giant's annual developer conference, in San Francisco.In January, Motorola's former CEO told British press that Google's Nexus 6 would have had a fingerprint scanner if Apple hadn't acquired the company responsible for its biometric tech.Former Motorola CEO Dennis Woodside (who now leads Dropbox), told The Telegraph in an interview that a dimple on the handset's back was supposed to feature an integrated sensor, but its supplier couldn't meet its quality demands.
