Abstract
A client filter is provided for filtering data to and from network servers. The filter has connection with a token that holds licenses which include cryptographic keys. Any data that is downloaded or uploaded over a network goes through the filter before it is presented for the user or a server. The filter identifies tags in the data and uses information in the licenses to determine the data that will pass through the filter. For uploading, the filter encrypts the tagged data with a chosen license. For download, the tagged data is decrypted if a proper license is found and the data is presented for the user.
