Abstract
Official abstract text for this publication.
A series of touch panel key entries may be secured by shuffling touch entry coordinates. In one embodiment, the entries may be secured by applying a shuffling algorithm that replaces the true coordinates with other incorrect coordinates. Then the correct data may be reassembled in a secure environment.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: securing a series of input touch screen coordinates in a protected screen region by remapping the coordinates to different coordinates within the protected region. 2. The method of claim 1 including shuffling using one of a Thorp or Knuth shuffle. 3. The method of claim 1 including shuffling in a secure environment. 4. The method of claim 1 including sharing a symmetric…
