Abstract
A computer related security mechanism requires that a human participate in an access verification sequence. Upon a request to access secure data, a puzzle is provided to the requester. Proper solution of the puzzle requires human participation. The puzzle is chosen such that its solution is within the capabilities of a human, but beyond the current state of the art for computer systems. The puzzled can be visually and/or audibly rendered to the user. In one configuration, the puzzle is obtained via a library of pluggable puzzle generators. Puzzle generators in the library can be replaced as the state of the art of computing technology improves.
