A system for providing secured file transfer protocol (“FTP”) services between a passive FTP client system coupled to a private network and a FTP server coupled to a public communication network, such as the Internet. The passive FTP client system requests a communication session with a first proxy server that is coupled to the private network. The passive FTP client system submits to the first proxy server the uniform resource locator (“URL”) of a desired FTP server. The first proxy server initiates an outbound request from the private network, through a single port on a firewall, to a second proxy server that is coupled to the public communication network. The first proxy server submits the URL to the second proxy server. The second proxy server uses the URL to establish a FTP session with the desired FTP server. Upon receiving an identified socket provided by the FTP server for the data channel, the first proxy server changes the received data packets from the FTP server by substituting its own IP address for the FTP server's IP address, thus identifying a new socket on the first proxy server. The passive FTP client system transmits a FTP data request to the new socket on the first proxy server. The first proxy server forwards the data request to the FTP server via the outbound connection established with the second proxy server. All FTP data flows through a single port on the firewall.

The present invention includes a system for and methods of storing and comparing computer generated vector lines through an insecure or a secure communication channel. A continuous vector line (CVL) identifier includes from an ordered collection of 2 or more points. Using an input device (such as computer keyboard, finger, soft keypad, or any other input from body movements or input from electrical current or impulses, or input from human or mechanical sound waves) to a physical machine, or through a token (such as credit card, USB token, which can be carried around by user), a user enters and sends their unique identifier and reference code (such as a personal identification number (PIN), and/or password or other secret code) to the physical machine by making a contact or contact-less to the computer system. As part of the enrollment process the user inscribes a pre-determined set of continuous vector lines (CVLs). The CVLs include data points that are collected from any computer pointing device, such as a mouse, stylus or a digitizer tablet, in a specific format, using a push down anatomical technique and are sent to local active content (such as a library, or a program, or an add-on to the Internet browser such as ActiveX) or a remote server for further analysis of the two CVL's. A user should go through an Enrollment and Verification process to capture the data points and this process uses a two factor authentication and a verification scheme. The collected data points that represent a CVL profile made previously is kept in a database, registry, or memory that can be encrypted and accessed by using a reference number or other unique identifier. Access is either locally or remotely through any wired or wireless medium such as the Internet, Secure File Transfer Protocol (SFTP) server, cellular network or other communication connection to enable the comparison of a newly generated CVL identifier to the CVL profile generated previously.
