Abstract
A method for delivering computer code to a plurality of processing units is disclosed. A first set of digital data is distributed to the plurality of processing units. The first set of digital data is unencrypted and comprises a content portion and an identification label. At least one of the processing units sends the identification label to a remote station. The remote station then encrypts a second set of digital data and delivers the encrypted code to the requesting processing unit. The requesting processing unit can decrypt the encrypted second set of digital data.
Claims20
A method for delivering displayable data to a plurality of processing units, each of said processing units being located in a separate remote site and connected to an output unit, said method comprising:
- providing a first and a second set of digital data, said first set of digital data comprising a content portion and an identification label, said content portion being displayable on said output unit, said second set of digital data being displayable on said output unit and related to said first set of digital data;
- distributing said first set of digital data to each of said plurality of processing units;
- receiving said identification label from at least a first and a second one of said processing units;
- after receiving said identification label from said first processing unit:
- generating a first encrypted digital data by encrypting said second set of digital data using a first key, and
- delivering said first encrypted digital data to said first processing unit;
- and
- after receiving said identification label from said second processing unit:
- generating a second encrypted digital data by encrypting said second set of digital data using a second key, and
- delivering to said second processing unit said second encrypted digital data.
A method for delivering displayable data to a plurality of processing units, each of said processing units being located in a separate remote site and connected to an output unit, said method comprising:
- providing a first and a second set of digital data, said first set of digital data being encrypted at a first level and comprising a content portion and an identification label, said content portion being displayable on said output unit, said second set of digital data being displayable on said output unit and related to said first set of digital data;
- distributing said first set of digital data to each of said plurality of processing units;
- receiving said identification label from at least a first and a second one of said processing units;
- after receiving said identification label from said first processing unit:
- generating a first encrypted digital data by encrypting said second set of digital data at a second level using a first key, and
- delivering said first encrypted digital data to said first processing unit;
- and after receiving said identification label from said second processing unit:
- generating a second encrypted digital data by encrypting said second set of digital data at a level different than said first level using a second key, and
- delivering to said second processing unit said second encrypted digital data.
