Abstract

The present anonymizer data collection device includes a suitable encryption process for encrypting a permanent identifier assigned to the subscriber or the subscriber equipment to produce an encrypted identifier. Information relating to the subscriber'"'"'s data use of the network is collected and tagged with the encrypted identifier to protect the identity of the individuals from which the data are collected.

Claims

1. A data collection device for protecting an identity of a subscriber while collecting subscriber data use information on a communications network, said communications network including a subscriber termination device with an associated unique identifier, the device comprising:

a means for monitoring a data routed on said communications network;

a means for collecting said subscriber data use information relating to said data routed on said communications network;

a means for encrypting said unique identifier to produce an encrypted identifier; and

a means for tagging said collected subscriber data use information with said encrypted identifier to obscure said unique identifier associated with said subscriber termination device.

2. A cable anonymizer data collection device for collecting subscriber data use information as digital cable modem signals are transferred on a cable network between a subscriber cable modem with a unique MAC address and a cable modem termination system (CMTS) which interfaces said subscriber digital cable modem to the Internet, the data collection device comprising:

a means for monitoring said data routed on said cable network;

a means for collecting said subscriber data use information relating to said data routed on said cable network;

a means for encrypting said MAC address to produce an identifier; and

a means for tagging said collected subscriber data use information with said identifier to obscure the identity of a subscriber from which said data is collected.

3. A method for collecting subscriber data use information as data is transferred on a network between a subscriber modem with a unique identifier and a network termination system which interfaces said subscriber modem to the Internet, said subscriber modem having a unique network number which correlates to a subscriber IP address, the method comprising the steps of:

receiving said data at said network termination system;

converting a one of said network address and said IP address to the other one of said network address and said IP address for transmission of said data over a corresponding one of said network and the Internet;

encrypting said one of said network address and said subscriber IP address to produce an identifier;

collecting said subscriber data use information at said network termination system; and

tagging said collected subscriber data use information with said identifier to protect an identification of a subscriber from which said subscriber data use information was collected.

4. A method for anonymously collecting subscriber data use information as data are transferred on a cable network between a subscriber cable modem and a cable modem termination system (CMTS) which interfaces said subscriber cable modem to the Internet, the method comprising:

collecting said subscriber data use information while a subscriber is using said cable network;

associating a unique address and a unique MAC address corresponding to said subscriber cable modem;

encrypting said MAC address to produce an identifier;

tagging said collected subscriber data use information with said identifier; and

storing said tagged subscriber data use information.
