The technology is most closely associated with authentication to online applications such as those running on desktop computers, mobile devices, and Internet of Things (IoT) nodes.
Apple Pay leverages its proprietary Touch ID fingerprint scanner on its proprietary iPhone line with, aside from cryptography, the added security of its Apple A7 system on a chip that includes a Secure Enclave hardware feature that stores and protects the data from the Touch ID fingerprint sensor.
Other distinctive features are that biometric tokenization can be implemented on other operating systems such as OSX, Microsoft Windows, Google Android for password-less login to desktop and mobile applications.
In order to achieve the highest level of privacy and protection when calculating and transmitting sensitive information, biometric tokenization leverages existing encryption algorithms, authentication protocols, as well as hardware trust zones.
Combining some or all of these methods maximizes the level of protection needed to uphold the integrity of the process and security of data that could otherwise expose users to a breach of trust on a mass scale.
