In an announcement to a packed auditorium at Mobile World Congress 2014 on the evening of the 24 February 2014, Samsung launched their latest flagship Galaxy smartphone, the S5, containing an integrated fingerprint sensor.
We still need more information on the specifics of how the sensor will operate and interact with the associated services but this is what we know.
The S5 fingerprint sensor is a swipe located on the front of the device underneath the physical home button.
In a promising move from Samsung, they have initially linked the sensor to four consumer and enterprise services that include:
- Phone unlock
- Private Mode protection. To protect important documents contained in a secure vault
- Mobile payments via the pre-installed PayPal app
- As part of a multifactor authentication (MFA) solution (Fingerprint + Password) for Knox 2.0 authentication
The mobile payments app is provided by PayPal who have been working on the development of the supporting ecosystem for a number of years. By leveraging a combination of hardware and software services that include:
- Integrated fingerprint sensor
- Hardware security environment provided by TrustZone (Secure Element, SE and Trusted Execution Zone, TEE)
- Secure authentication protocol and infrastructure (mobile client and server) as part of FIDO Alliance OSTP and commercialised by Nok Nok Labs
- Merchant service infrastructure to support PayPal mobile payments
Hill Ferguson, chief product officer, PayPal, commented on the development; "By working with Samsung to leverage fingerprint authentication technology on their new Galaxy S5, we are able to demonstrate that consumers don't need to face a tradeoff between security and convenience."
The fingerprint template is securely stored within the SE and is protected by ARM’s TrustZone environment. This makes it difficult to access or tamper with the biometric template and also allays privacy concerns of having to store a fingerprint in a networked database.
This is extremely positive news for the whole industry.
