Lifestyle authentication is used to verify a user's identity by referring to his or her life log data. Life logs are the history of the user stored in smartphones and other devices using information and communication technology (ICT). Verification of the user's everyday habits in his or her life logs is called lifestyle authentication.

Moreover, in lifestyle authentication, a combination of authentication factors can be changed flexibly. This makes it easy to use lifestyle authentication. Previously, multi-factor authentication used to require the user to handle a number of operations, thus offering his or her less convenience. Lifestyle authentication addresses this issue by referring to the user's daily activity patterns, which in turn help reduce stress on the user in the authentication process. The authentication factors include smartphone device information, positioning information, Wi-Fi information, shopping history, and data sent from wearable device sensors. This method makes it possible to leverage the existing information infrastructure and offer more flexibility to new authentication methods.
