Patent ID: 8144871

Claim:
A method for restricting access to information communicated between parties, comprising the following steps performed by computational equipment: first encoding of the information for obtaining a corresponding first encoded version of the information; second encoding said first encoded version for obtaining a corresponding second encoded version of the information; wherein one of said first and second steps of encoding results in said corresponding version being restricted from a first party decoding the information encoded therein due to not having access to a first decoding data; wherein another of said first and second steps of encoding results in said corresponding version being restricted from a second party decoding the information therein due to not having access to a second decoding data; first providing, to the second party, said second encoded version; subsequently, performing an activity upon receiving input from the first and second parties using one of: the information, or second information, for determining, according to a content thereof, a processing of the activity by the computational equipment, wherein the second information is operably different from the information for performing the processing; after completing the activity, second providing to the second party said second decoding data; wherein the second party then decodes the second encoded version using the second decoding data, and the first decoding data for obtaining the information; and wherein the information obtained from decoding by computational equipment is used to determine whether the activity was performed according to the information, or instead, according to the second information; wherein said activity includes a game, wherein the information includes an ordered collection of game token values to be presented to the second party in accordance with one or more game rules.
