Abstract
A method and apparatus for preventing the use of data involves creating a first association between a set of labels and a first set of codes, where the set of labels contains information to be displayed on a computer, while each code in the first set of codes is associated with a particular label. An encryption key is linked with the first association. The set of labels, the first set of codes, and the first encryption key are sent to the computer. Later, when codes from the first set of codes and the first encryption key are received back from the computer, the codes returned from the computer are then matched to labels from the set of labels using the first encryption key. Subsequent, different associations between the set of labels and other sets of codes are created, and additional encryption keys are also created to identify the subsequent associations.
