  Graphical passwords (GPWs) are in many areas of the current world.
Topological graphic passwords (Topsnut-gpws) are a new type of cryptography,
and they differ from the existing GPWs. A Topsnut-gpw consists of two parts:
one is a topological structure (graph), and one is a set of discrete elements
(a graph labelling, or coloring), the topological structure connects these
discrete elements together to form an interesting "story". Our idea is to
transform Chinese characters into computer and electronic equipments with touch
screen by speaking, writing and keyboard for forming Hanzi-graphs and
Hanzi-gpws. We will use Hanzigpws to produce text-based passwords (TB-paws). We
will introduce flawed graph labellings on disconnected Hanzi-graphs.
