Adapting authenticator to cryptocurrencies

[Rafael.Isuyama]

Greetings,

I work for a brazilian company that has developed an biometric authenticator for banking transactions. We would like to adapt it so that it also stores and executes cryptocurrencies transactions, preferably bitcoin. I know absolutely nothing, so I have to study quite a lot.
Are there any recommended sources, maybe a website or forum post to start learning? Thank you.

GreenAddress supports 2FA by means of multisig transactions, it's done very well. If you're looking for examples you should look there.

Try to read about Civiv and Stratis Identification apps, they have already works with fingerprints and you can log in tokenmarket via Civic app, may be with new iPhone you can use not only fingerprints, you will be able to authorize transactions with your face. Really good and actual idea.

Dear Sear! I recomend you take not blockchain generaly, not tach the bitcoin. You can bilt greate system for assuring documents and writing out to the blockbuster. If you consult with a corporative lawyer, he will give you wonderful pieces for the application of your device and blockchain.
