A tri-level authentication process comprises performing a biometrics-based authentication of a user of a portable device, performing an authentication handshake between the portable device and a content server, wherein the portable device includes a USB plug that plugs directly into a USB port of a host computer and the host computer is communicatively coupled to the content server, and performing a user authentication using a first key sent from the portable device to the content server, wherein access to restricted content on the content server by the user is enabled if the biometrics-based authentication, the authentication handshake, and the user authentication using a first key are all successful. The process may also include encrypting restricted content received from the content server using a private key before storing the restricted content in a non-volatile memory of the portable device.

What is claimed is: 1. A portable anti-piracy device comprising: a biometric sensor coupled to a biometric verification unit, the biometric verification unit configured to compare biometric information detected by the biometric sensor with a stored biometric template and to indicate a successful biometric authentication if the biometric information matches the stored biometric template; a processor coupled to the biometric verification unit; a memory coupled to the processor, the memory configured to store a biometric template, a private key, and a public key; a Universal Serial Bus (USB) plug coupled to a USB controller that is coupled to the processor and plugs directly into a USB port of a host system; an encryption unit coupled to the processor; a flash memory coupled to the encryption unit, the processor configured to perform an authentication handshake with a content server over a network via the host system if the biometric verification unit indicates a successful biometric authentication, and to send the public key to the content server if the authentication handshake is successful, the encryption unit configured to encrypt restricted content received from the content server using the private key and to store the encrypted restricted content in the flash memory, and a hashing algorithm configured to hash the public key before the processor sends the public key to the content server. 2. The portable anti-piracy device of claim 1, further comprising a tamper proof unit configured to erase data stored in the flash memory if the tamper proof unit detects tampering of the portable anti-piracy device. 3. The portable anti-piracy device of claim 1, further comprising a tamper proof unit configured to erase data stored in the memory if the tamper proof unit detects tampering of the portable anti-piracy device. 4. The portable anti-piracy device of claim 1, wherein the authentication handshake includes receiving a device authentication request from the content server and sending a device authentication reply to the content server. 5. The portable anti-piracy device of claim 4, wherein the device authentication reply includes one or more authentication sequences. 6. The portable anti-piracy device of claim 1, wherein the flash memory has a capacity of one gigabyte. 7. The portable anti-piracy device of claim 1, wherein the public key is representative of a user's identity.
