Security tracking of computer resources

Abstract

An allocation system that tracks allocation of computer resources is provided. The allocation system allocates a number of user-periods to an organization for accessing a computer resource. The allocation system determines a depletion date based on the number of user-periods and number of users. When a new user is added, the allocation system re-determines the depletion date based on an additional user. When a user is removed, the allocation system re-determines the depletion date based on one less user. When an additional number of user-periods are allocated to the organization, the allocation system re-determines the depletion date based on the additional number of user-periods.

I/we claim: 
     
         1 . A method performed by a computing device for tracking allocation of computer resources, the method comprising:
 allocating a number of user-periods to an organization for accessing a computer resource;   determining a depletion date based on the number of user-periods and number of users;   when a new user is added, re-determining the depletion date based on an additional user;   when a user is removed, re-determining the depletion date based on one less user; and   when an additional number of user-periods are allocated to the organization, re-determining the depletion date based on the additional number of user-periods.   
     
     
         2 . The method of  claim 1  further comprising determining whether a current date is within a warning threshold of the depletion date. 
     
     
         3 . The method of  claim 2  further comprising sending a notification to the organization when the current data is within a warning threshold of the depletion date 
     
     
         4 . The method of  claim 1  wherein the determining of the depletion date comprises setting the depletion date to a sum of the current date and a quotient of the number of user-periods divided by the number of users. 
     
     
         5 . The method of  claim 1  wherein the re-determining of the depletion date based on an additional user comprises setting the depletion date to a sum of the current date and a quotient of a current depletion period divided by a ratio of the number of users to the number of users plus one. 
     
     
         6 . The method of  claim 1  wherein the re-determining of the depletion date based on one less user comprises setting the depletion date to a sum of the current date and a quotient of a current depletion period divided by a ratio of the number of users to the number of users minus one. 
     
     
         7 . The method of  claim 1  wherein the re-determining of the depletion date based on the additional number of user-periods further comprises adding to the current depletion date a quotient of the additional number of user-periods divided by number of users. 
     
     
         8 . A computing device for tracking allocation of computer resources, the device comprising:
 a computer-readable storage medium storing computer-executable instructions comprising instructions that:
 allocate a number of user-periods to an organization for accessing a computer resource; 
 determine a depletion date based on the number of user-periods and number of users; and 
 when an additional number of user-periods are allocated to the organization, re-determine the depletion date based on the additional number of user-periods; and 
   a processor for executing the computer-executable instructions stored in the computer-readable storage medium.   
     
     
         9 . The computing device of  claim 8  wherein the instructions further comprise instructions that when a new user is added, re-determine the depletion date based on an additional user. 
     
     
         10 . The computing device of  claim 8  wherein the instructions further comprise instructions that when a user is removed, re-determine the depletion date based on one less user. 
     
     
         11 . A computer-readable storage medium storing computer-executable instructions for controlling a computing device to track allocation of computer resources, the instructions comprising:
 instructions that allocate a number of user-periods to an organization for accessing a computer resource;   instructions that determine a depletion date based on the number of user-periods and number of users;   instructions that when a new user is added, re-determine the depletion date based on an additional user; and   instructions that when a user is removed, re-determine the depletion date based on one less user.   
     
     
         12 . The computer-readable storage medium of  claim 11  further storing instructions that when an additional number of user-periods are allocated to the organization, re-determine the depletion date based on the additional number of user-periods.
