Abstract

A system and method of managing multiple users of an open metering system, wherein the users have different access privileges, includes the steps of providing a user password system for vault access; programing the vault with a plurality of transition states operatively relating to the user password system; assigning vault functional access to each user password first entered into the user password system; and performing a requested vault function when an entered user password under which the request is made has been assigned vault functional access for the requested vault function. The vault is manufactured in a first state in which the user password system is not activated and the activates the user password system upon entry of an initial user password which changes the vault to a second state that accepts requests for vault functions. The vault is changed to a third state from the second state wherein the user password system remains activated but another user password must be entered before a further request for a vault function is accepted. The requested vault function is rejected when the entered user password under which the request is made has not been assigned vault functional access for the requested vault function.

Claims

1. A method of managing multiple users of an open metering system, wherein the users have different access privileges, the method comprising the steps of:

providing a user password system for vault access;

programing the vault with a plurality of transition states operatively relating to the user password system;

assigning vault functional access to each user password first entered into the user password system; and

performing a requested vault function when an entered user password under which the request is made has been assigned vault functional access for the requested vault function.

2. The method of claim 1, comprising the further steps of:

manufacturing the vault in a first state in which the user password system is not activated; and

activating the user password system upon entry of an initial user password which changes the vault to a second state that accepts requests for vault functions.

3. The method of claim 2, comprising the further step of:

changing the vault to a third state from the second state wherein the user password system remains activated but another user password must be entered before a further request for a vault function is accepted.

4. The method of claim 1, comprising the further step of:

rejecting the requested vault function when the entered user password under which the request is made has not been assigned vault functional access for the requested vault function.

5. A transaction evidencing system, comprising

a personal computer (PC) including processor, memory and storage means, said storage means including at least one non-metering application program that is selectively run on said PC;

an unsecured printer operatively coupled to said PC for printing in accordance with said non-metering application program;

vault means operatively coupled to said PC, said vault means including digital token generation means and transaction accounting means, said vault means further including a user password system for vault access, said vault access including functional access based on an entered user password;

means in said PC for interfacing with said non-metering application program, said interfacing means issuing a request for at least one digital token in response to a request for indicia from said non-metering application program, said request for digital token including predetermined information required by said token generation means;

means in said PC for communicating with said vault means, said communicating means sending said request for digital token to said vault means and receiving from said vault means a digital token generated by said token generation means; and

means in said PC for generating an indicia bitmap from said digital token, wherein said interfacing means sends said indicia bitmap to said non-metering application program;

wherein a requested vault function is performed by the vault means when an entered user password under which the request is made has been assigned vault functional access for the requested vault function.

6. The transaction evidencing system of claim 5 wherein said vault means comprises a portable vault card that is removably coupled to said PC, said PC including means for removably coupling said vault card to said PC.

7. The transaction evidencing system of claim 5 wherein said vault means is manufactured in a first state in which the user password system is not activated, said vault means activating the user password system upon entry of an initial user password which changes the vault to a second state that accepts requests for vault functions.

8. The transaction evidencing system of claim 7 wherein said vault means changes to a third state from the second state under certain conditions wherein the user password system remains activated but another user password must be entered before a further request for a vault function is accepted.

9. The transaction evidencing system of claim 8 wherein said certain conditions include excessive vault idle time, vault power down and user log-out.

10. A transaction evidencing system, comprising

a personal computer (PC) including processor, memory and storage means, said storage means including at least one non-metering application program that is selectively run on said PC;

an unsecured printer operatively coupled to said PC for printing in accordance with said non-metering application program;

vault means operatively coupled to said PC, said vault means including digital token generation means and transaction accounting means, said vault means further including a user password system for vault access, said vault access including functional access based on an entered user password;

means in said PC for interfacing with said non-metering application program, said interfacing means issuing a request for at least one digital token in response to a request for indicia from said non-metering application program, said request for digital token including predetermined information required by said token generation means;

means in said PC for communicating with said vault means, said communicating means sending said request for digital token to said vault means and receiving from said vault means a digital token generated by said token generation means; and

means in said PC for generating an indicia bitmap from said digital token;

wherein a requested vault function is performed by the vault means when an entered user password under which the request is made has been assigned vault functional access for the requested vault function.
