Data handling method
First Claim
1. A data handling method comprising:
- a step of associating display content of data to be distributed with user environment information including user license information, user authentication result information and user operation information, and generating data generation information related to a method for reproducing data based on the display content;
a step of processing the data to be distributed based on the data generation information, storing the data generation information in the data to be distributed, and layering and distributing the data;
a step of obtaining the user environment information of a user attempting to utilize the data, and looking up the data generation information included in the distributed data to select a data reproduction method that corresponds to the user environment information; and
a step of reproducing the distributed data based on the selected data reproduction method.

Abstract
A data handling method is presented, which prevents unauthorized use of digital content, and in particular, prevents unauthorized secondary use of cache files stored in PCs of users who have downloaded digital content from a web server, and prevents secondary use by dead-copying of image data that is presented on a display. The data handling method includes a step of associating display content of data to be distributed with user environment information, and generating data generation information related to a method for reproducing data based on the display content; a step of processing the data to be distributed based on the data generation information, storing the data generation information in the data to be distributed, and layering and distributing the data; a step of obtaining the user environment information and looking up the data generation information included in the distributed data to select a data reproduction method; and a step of reproducing the distributed data.
