Abstract

Several embodiments of computer security systems are described and which are adapted to grant an authorized individual access to a secured domain, such as a computer or data stream. In one embodiment, the security system comprises: an analyzing means for receiving first and second passwords, each of said passwords being transmitted over a first communication channel, analyzing said first password, transmitting a first signal output only if said first password is authorized, and granting access to said secured domain only if said second password is substantially identical to a code; and a random code generating means for generating said code, transmitting said code over a second communication channel upon receipt of first signal output, and transmitting said code to said analyzing means; and a notification means for receiving said code and for notifying said authorized individual of the identity of said code.

Claims

1. A security system adapted to grant an authorized individual access to a secured domain, said security system comprising:

first and second communications channels, said first communication channel being adapted to receive a first password from a first individual and to communicate and receive a second password from a second and authorized individual; and

software means, communicatively coupled to said first and to said second communication channels, for receiving said first password from said first individual and for generating and transmitting a second password on said second communications channel to said second and authorized individual and for receiving said second password by use of said first communications channel, and for granting access to said secured domain only if second password is received from said second and authorized individual.

2. A security system adapted to grant an authorized individual access to a secured domain, said security system comprising:

first and second communications channels, said first communications channel being adapted to receive a first password from a first individual and to communicate and receive a second password from a second and authorized individual; and

software means, communicatively coupled to said first and to said second communication channels, for receiving said first password from said first individual and for generating and transmitting a second password on said second communication channel to said second and authorized individual and for receiving said second password by use of said first communication channel, and for granting access to said secured domain only if second password is received from said second and authorized individual within a predetermined time after said second password has been transmitted by said software means on said second channel.

3. A security system adapted to grant an authorized individual access to a secured domain, said security system comprising;

a computer connected to a first and second communication channels and being adapted to receive a first password from an individual on said first communications channel and to compare said first password with a table of information and to generate and communicate a second password on a second communications channel to a second individual, the identity of said second individual and said second communications channel being specified by said table of information.

4. The security system of claim 3 wherein said first and said second individuals are identical.

5. The security system of claim 4 wherein said first and said second communication channels are identical.

6. A security system adapted to grant an authorized individual access to a secured domain, said security system comprising:

first and second communications channels, said fast communication channel being adapted to receive a first password from a first individual and to communicate and receive a second password from a second and authorized individual; and

a computer assembly, communicatively coupled to said first and to said second communication channels, for receiving said first password from said first and to said second communication channels, for receiving said first password from said first individual and for generating and transmitting a second password on said second communications channel to said second and authorized individual and for receiving said second password by use of said first communications channel, and for granting access to said secured domain only if second password is received from said second and authorized individual.

7. A security system adapted to grant an authorized individual access to a secured domain, said security system comprising;

first and second communications channels, said first communications channel, being adapted to receive a first password from a first individual and to communicate and receive a second password from a second and authorized individual; and

a computer assembly, communicatively coupled to said first and to said second communication channels, for receiving said first password from said first individual and for generating and transmitting a second password on said second communication channel to said second and authorized individual and for receiving said second password by use of said first communication channel, and for granting access to said secured domain only if second password is received from said second and authorized individual within a predetermined time after said second password has been transmitted by said computer assembly on said second channel.
