Abstract: Multi-factor authentication using quantum communication (“QC”) includes stages for enrollment and identification. For example, a user enrolls for multi-factor authentication that uses QC with a trusted authority. The trusted authority transmits device factor information associated with a user device (such as a hash function) and user factor information associated with the user (such as an encrypted version of a user password). The user device receives and stores the device factor information and user factor information. For multi-factor authentication that uses QC, the user device retrieves its stored device factor information and user factor information, then transmits the user factor information to the trusted authority, which also retrieves its stored device factor information.

Abstract: A system for preventing redirection loops during collaborative web browsing is provided including: a CPU; a memory in communication with the CPU; instructions stored in the memory and executable by the CPU to prevent redirects encountered during a collaborative web browsing session, the instructions further comprising: instructions enabling a device to join a collaborative web browsing session; instructions enabling detection of a redirection loop based upon a query to a uniform resource locator (URL) history stored in a memory; and instructions enabling termination of the redirect loop; wherein, upon the detection of a redirection loop, the device ignores URL updates of the collaborative web browsing session for a predetermined amount of time.
