  • the network 130 is the Internet.
  • a remote system 140 contains the private area that the local system 120 is trying to connect to. Other systems 150, 160 may be accessed through the network as well. Because the network 130 is not secure, the security mechanism described below is used to restrict access to the private area.

  • the remote system may further include an encryption unit 240.
  • the encryption unit 240 encrypts and decrypts using public and private keys.

  • the remote system further includes an access control unit 250.
  • the access control unit 250 controls access to the user data 260.
  • the access control unit 250 receives indication from the fingerprint recognition unit 230 whether the template matched the fingerprint sent by the user.
  • the identity verification unit 250 receives indication from the encryption unit 240 whether the public key decrypted the file sent by the user encrypted with the user's fingerprint based private key.
  • the access control unit 250 only permits access to the user data 260 when a match was found.
  • the user data 260 may be actual data, various application programs, or anything that the user may have access to.
  • the user data 260 may include the operating system of the computer. That is, the user may remotely adjust the operation of the remote system 140.
  • multiple users may have private areas within the same user data block 260. Each user is permitted access only to his or her private area.
  • FIG. 3 illustrates the local system that is used to access the private area.
  • the local system 110 includes a system area 310, which may store the operating system, various application programs, and other files.
  • the local system 110 further includes a network access unit 320.
  • the network access unit 320 provides a network connection such as Ethernet, ISDN, Tl, etc.
  • the network access unit 320 may provide a network connection via a modem.
  • the local system 110 may further include a scanner interface 330.
  • the scanner 120 is coupled to the local system 110.
  • the scanner interface 330 receives a digitized fingerprint image from the scanner.
  • the scanner interface 330 may further extract a template from the digitized fingerprint image.
  • the local system may further include an encryption unit 340.
  • the encryption unit 340 encrypts and decrypts using public and private keys.
  • the encryption unit generates the private and public keys of the user from the fingerprint data received by the scanner interface 330.
  • the encryption unit 340 generates a fingerprint template from the fingerprint data received by the scanner interface 330. This fingerprint template is sent to the remote system 140.
  • Figure 4 is a flowchart illustrating the process of creating the private space.
  • the remote access system is set up. For one embodiment, this includes adding server software to the remote system.
  • the remote system receives a fingerprint template from the user.
  • the remote system receives an actual digital image of the fingerprint.
  • the remote system receives a template including extracted features of the fingerprint.
  • the remote system receives other data representing various characteristics of the fingerprint.
  • This fingerprint template is received either locally, or remotely with validation.
  • the user may set up the private space locally, for remote access.
  • validation may be a digital certificate, or an encryption verification method. Since the private space at this point does not contain any data, the security of this step is not vital.
  • private space is allocated to the user.
  • actual space is allocated to the user.
  • flexible allocation may be made, permitting the user to store varied amounts of data, and reallocating space as needed. However, this establishes an area for the user's data.
  • the fingerprint template is stored within the remote system to control access to the private space.
  • the template is stored in the access control unit 250 of the remote system.
  • the access control unit 250 is enabled, and access to the private space is routed through the access control unit 250. At this point, the user needs to be validated in order to access the private space.
  • Figure 5 is a flowchart illustrating the process of logging into the private space
  • the remote system receives an access request.
  • the user may request access by entering the remote system's IP address into a web browser.
  • the remote system responds with a request for validation.
  • the request for validation may specifically request a fingerprint.
  • the user now has to place his or her finger on the fingerprint scanner 120 attached to the user's local system. This fingerprint information is transmitted to the remote system.
  • the fingerprint information is received by the remote system.
  • the fingerprint information is a digital image of the fingerprint.
  • the fingerprint information may be a list of extracted features of the fingerprint, or other data. Some of the processing for creating this information may occur in the user's local system.
  • the fingerprint information is compared with the fingerprint template associated with the private space. For one embodiment, if there are multiple private spaces within the remote system, the user requests his or her own private space by entering a handle or name. For another embodiment, the user merely attempts to access the remote system, and the matching is to all fingerprint templates within the remote system.
  • the fingerprint recognition unit 230 of the remote system manipulates the data of the fingerprint image and the fingerprint template to be in the same format. If the information does not match the template, the process continues to block 560, and the user is denied access to the private space. If the information matches the template, the process continues to block 570, and the user is allowed access to the private space. For one embodiment, after the user is allowed access, a one-time session key is exchanged with the user for further verification during the access period. For another embodiment, the remote system periodically challenges the user's local system for re-verification.
  • Figure 6 illustrates another embodiment of the registration process.
  • the remote access system is set up.
  • the remote system receives a digital certificate of the user.
  • Digital certificates are known in the art. They are used to verify the identity of a user.
  • the digital certificate includes the public key of the user. This public key is generated based on the fingerprint of the user.
  • the public key of the user is extracted from the digital certificate. For one embodiment, this involves decrypting the digital certificate with the certifying authority's public key.
  • the public key of the user is verified. For one embodiment, this is done by receiving a file encrypted with the private key that corresponds to the public key of the user. Decrypting this file with the user's public key verifies that the user is in fact associated with the public key included in the digital certificate. Because the private key is generated based on an actual fingerprint image of the user, the user's identity is also verified.
  • the user's public key is stored in the system. And at block 660, space is allocated for the user.
  • Figure 7 is a flowchart illustrating the process of logging into the private space.
  • the remote system receives a request for access to the private space.
  • the remote system sends a request for a file encrypted the user's private key.
  • the private key is fingerprint based, and therefore also verifies that the actual user associated with the private key is sitting in front of the computer system.
  • the remote system receives the file encrypted with the fingerprint based private key.
  • the remote system retrieves the public key associated with the user, and attempts to decrypt the file sent by the user.
