A communication system comprises means defining a communication region, such as a touch-pad, having associated therewith a plurality of symbols or the like and being responsive to a user-controlled pointing device whereby a desired symbol or the like can be selected by movement of the pointing device in a predetermined direction within the region. The method includes creating a token and populating a payload section of the token with key material and selecting a wrapping method that specifies how the key material is securely bound to key control information, wherein a structure of the key control information in the token is independent of the wrapping method. The middle exercise area has a domed shape and curves downwardly to the four sides. Each metadata has an associated meta-metadata, which describes a variance to the metadata.
