Abstract

A system and method are provided for enabling and recording operations relating to computers and computer peripheral equipment wherein sensitive or secret data is to be entered and stored or processed and data of a similar nature is accessible from memory or calculating circuits. In particular, the invention involves electronic means for sensing or scanning one or more physical characteristics of a person or persons to enter and/or receive data from a computer and generating signals indicative of such physical characteristic(s) which signals are automatically analyzed and compared with signals for enabling the operation of the computer. In addition, a code signal or signals are generated which is used to identify the person entering and receiving data from the computer, which code signal is recorded for record purposes along with information indicative of the information entered and/or received from the computer. Such information may be provided on-line at a monitor station remote from a data entry and retrieval station or readily available from memory for routine analysis during auditing or investigation of error or fraud. In a particular form of the invention, both the presence of a person at a computer terminal and an identifying characteristic of such person are sensed and used to enable the entry and retrieval of data.

Claims

1. A method of detecting fraud in the operation of a computer system, said method comprising:

a) identifying by means of information signals all the operators authorized to operate an electronic computer system having a plurality of data entry and display terminals, and

b) whenever data is entered into said system, generating a select information signal in the form of code identification signals which are unique to a person physically present at one of said data terminals for entering the data,

c) only upon determining said physically present person as one of said authorized operations, recording said code identification signal along with signals indicative of the information entered,

d) when it is desired to audit and determine the identification of the person entering specific information into the computer system, reproducing the signals indicative of the specific information to be audited along with code identification signals of the person entering said information, and

e) applying said code identification signals to activate a visual presentation means to cause the visual presentation means to present visually readable information indicating the identity of the person associated with such code signals.

2. A method in accordance with claim 1 wherein

the code identification signals unique to said physically present person are generated by electronically detecting such physically present person and generating detection signals,

comparing said detection signals with signals generated by reproducing code signals of a plurality of persons authorized to enter data into the computer, and then

when a match occurs between said detection signal and the signal recorded in the memory thereby identifying said physically present person, generating said code identification signals.

3. A method in accordance with claim 2 wherein

the step of electronically detecting and identifying the physically present person entering data into the system is effected by automatically analyzing speech signals derived from said person speaking into a microphone.

4. A method in accordance with claim 3 wherein

the speech signals generated by said physically present person to be identified are generated from specific words spoken into a microphone by such person.

5. A method in accordance with claim 2 wherein

an automatic identification of said physically present person to be identified is effected by electro-optically scanning an image of the face of said person and generating a video signal derived from such scanning,

automatically processing said video signal by digitizing same, and

comparing the results of such processing with signals reproduced from a memory in which is stored video scanned images of the faces of all persons authorized to enter data into said system.

6. A method in accordance with claim 1 including

identifying the person seeking to enter data into said system by electronically analyzing speech signals generated by such person speaking into a microphone, and

upon effecting such identification that such person is authorized to operate said computer system, generating an enabling signal to enable such person to enter data into said system.

7. A method in accordance with claim 1 wherein

the code identification signals are derived from the output of a television camera scanning the face of the person entering data at one of said data entry and display terminals.
