Patent ID: 7945670

Claim:
A system for determining whether to allow at least one token to pass through at least one control point, said system comprising: a plurality of distributed components, each of the distributed components being associated with a given control point and operative: to store at least a subset of data associated with each token which may be allowed to pass through the control point; and to determine whether to allow a given token, which may be allowed to pass through the control point, to pass through the control point based at least in part on at least a portion of the data stored by the distributed components; and a master server operative to determine the subset of data associated with each token to be stored on each of the distributed components associated with a control point through which the token may be allowed to pass; wherein, for a given token, at least one member of at least a primary subset of the distributed components associated with at least one control point through which the given token may be allowed to pass stores a different subset of the data associated with that token than at least one member of at least a secondary subset of the distributed components associated with at least one control point through which the given token may be allowed to pass.
