Patent attributes
A network interface device can (i) detect electronic communications from a telecommunications network; (ii) extract an access request for protected data; and (iii) extract browser information about a browser on a user device used by a user to initiate the access request. The access request can include a network address of a device from which the electronic communications were transmitted. The browser information can indicate a time zone associated with the browser. The network address and the browser information can be independent of data about the user and of data transmitted from the network interface device. The network address and stored data about network addresses can be used to determine a time zone for the device. A result of comparing the time zones can be used to determine a level of authentication to require before allowing the protected data to be transmitted to the user device.
