A method for providing data access control over information networks comprises coupling a control device to a digital processing system, obtaining user identification by executing a user authentication process, retrieving initialization information from a first memory unit of the control device in response to a request from an information provider received over the information network when user's identity is authenticated, providing the initialization information to the information provider via the information network through the digital processing system, establishing a communication between the control device and the information provider over the information network when an acknowledgement of user identity is received, obtaining information from the information provider over the information network, and storing the information in a second memory unit of the control device.

What is claimed is: 1. A method for providing data access control over information networks comprising: coupling a control device to a digital processing system by coupling a Universal Serial Bus ("USB") protocol connector to a USB receptacle of the digital processing system; obtaining user identification by executing a user authentication process, the user authentication process including activating a fingerprint detector to detect user's fingerprint, obtaining user's fingerprint from the fingerprint detector, retrieving a fingerprint file from a first memory unit of the control device, and authenticating user's fingerprint in response to the fingerprint file; retrieving initialization information from the first memory unit of the control device in response to a request from an information provider received over the information network when user's identity is authenticated, the initialization information including a security code associated with the information provider and a public key associated with the information provider; providing the initialization information to the information provider via the information network through the digital processing system, providing the initialization information to the information provider including sending the security code to the information provider via the information network and encrypting the public key before sending the public key to the information provider via the information network; establishing a communication between the control device and the information provider over the information network when an acknowledgement of user identity is received; obtaining information from the information provider over the information network; and storing the information in a second memory unit of the control device. 2. The method of claim 1, wherein the digital processing system further includes a connection to at least one of Internet, Intranet, wide area network ("WAN") and local area network ("LAN"). 3. The method of claim 2, wherein the step of obtaining information from the information provider over the information network further includes: sending an on-line transaction request to the information provider over the information network; and receiving the information over the information network in response to the on-line transaction request. 4. The method of claim 2, wherein the step of obtaining information from the information provider over the information network further includes: sending a request for accessing a restricted Internet site to the information provider over the information network; and receiving the information over the information network in response to the request after the request is verified. 5. The method of claim 2, wherein the step of obtaining information from the information provider over the information network further includes: sending a request of service or upgrades to the information provider over the information network; and receiving the information over the information network in response to the request after the request is verified. 6. The method of claim 1, further comprising running navigation software to display the information stored in the second memory unit of the control device. 7. A method of anti-piracy for providing controlled dissemination of information through computer networks, the method comprising: coupling an anti-piracy device to a host system by coupling a Universal Serial Bus ("USB") protocol connector to a USB receptacle of the host system; obtaining user's fingerprint from a fingerprint sensor; verifying user's identity according to fingerprint data stored in a first memory unit of the anti-piracy device; retrieving a public key associated with the user from the first memory unit of the anti-piracy device in response to a request from an information provider when the user's identity has been verified; encrypting the public key; providing the public key and a security code to the information provider via a computer network through the host system; establishing a communication between the anti-piracy device and the information provider over the computer network when a message of verified public key is received; obtaining information from the information provider over the computer network; and storing the information in a second memory unit of the anti-piracy device. 8. The method of claim 7, wherein the host system further includes a connection to at least one of Internet, Intranet, wide area network ("WAN") and local area network ("LAN"). 9. The method of claim 7, wherein the step of obtaining information from the information provider over the computer network further includes: sending a request for accessing a restricted Internet site to the information provider over the computer network; and receiving the information over the computer network in response to the request after the request is verified. 10. The method of claim 7, wherein the step of obtaining information from the information provider over the computer network further includes: sending a request of service or upgrades to the information provider over the computer network; and receiving the information over the computer network in response to the request after the request is verified. 11. The method of claim 7, wherein the step of storing the information in a second memory unit of the anti-piracy device further includes encrypting the information in response to a private key before the information is stored in the second memory unit of the anti-piracy device. 12. The method of claim 7, further comprising: retrieving the information from the second memory unit of the anti-piracy device; decrypting the information; and running navigation software to display the information. 13. The method of claim 7, further comprising: loading tamper proof code into an execution sequence when one of voltage, frequency and temperature detecting devices detects tampering; and executing the tamper proof code. 14. The method of claim 7, wherein the obtaining information from the information provider over the computer network further includes: sending an on-line transaction request to the information provider over the computer network; and receiving the information over the computer network in response to the on-line transaction request.
