SECURITY AUTHENTICATION METHOD FOR CREATING SECURITY KEY BY COMBINING AUTHENTICATION FACTORS OF MULTIPLE USERS

摘要

The present invention relates to a security authentication method for creating a security key by combining authentication factors of multiple users and, more specifically, to a security authentication method for creating a security key by combining authentication factors of multiple users, whereby information is collected from multiple users in a smart terminal-based security authentication environment and, when creating a security key by combining the collected information of the multiple users as authentication factors, the authentication factors of the multiple users are randomly and multidimensionally cross-combined, thereby creating a new security key. The present invention has the effects that identification information automatically collected through a smart terminal is used as authentication factors, and a security key is created by way of random, multidimensional cross-combination thereof, thereby providing a security service strengthened through multilateral cooperation, and applying same to various fields of application in combination with existing authentication and encryption techniques.
