On magic matching sets having many magic parameters in information networks

Graphical passwords have been proposed as a possible alternative to text-based schemes, but graphical passwords, in storage and communication, require much more storage space than text based passwords, and network transfer delay is also a concern for them. An idea of "graphical structure plus number theory" (GSPNT) for designing new type of passwords is an alternative to typical graphical passwords. Magic matching set having many magic parameters is one of graphical passwords produced by GSPNT. Some results on magic matching sets are obtained and interesting problems are proposed at the end of this article.
