Patent

CA 2398761

The invention discloses a method and system for dynamically modifying files in a shared file network, such as Peer to Peer network. Files may be modified by inserting advertising into the file before passing it on to the end user. Files may be modified to create audible artifacts thus making them less likely to be copied by an end user. The audible artifacts may be removed should the user pay a licensing fee for the file. Files may also be modified to add digital rights management information so that the file may not be utilized without the appropriate key. Files may also be modified by inserting tracking information to include such information as the date of download and the IP address of the site providing the file.
