Abstract
Abstract A security system for use with an indicia printing authorization device includes a computer having a nonvolatile memory associated therewith. Graphic change information can be downloaded to the device by an external authority. The graphic change information includes the data when the different pattern is authorized. On that date, all indicia printers that do not print the authorized pattern will be suspect.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
131 words
A security system comprising: authorization means for authorizing the printing of an indicia pattern, said authorization means including means for storing a plurality of indicia patterns; selection means, remote from said authorization means, for selecting one of said indicia patterns to be printed by said authorization means; control means, remote from said authorization means, for controlling said selection means for securing the selection of said one of said indicia patterns; communication establishing means for establishing communication between aid selection means and said authorization means such that the indicia pattern printed can be used to verify the security of said authorization means; and said plurality of indicia patterns including a first graphic pattern and a second graphic pattern, and said second graphic pattern being the color reverse of said first graphic pattern.
Claim 2
Dependent Claim
131 words
A security system comprising: authorization means for authorizing the printing of an indicia pattern, said authorization means including means for storing a plurality of indicia patterns; selection means, remote from said authorization means, for selecting one of said indicia patterns to be printed by said authorization means; control means, remote from said authorization means, for controlling said selection means for securing the selection of said one of said indicia patterns; communication establishing means for establishing communication between aid selection means and said authorization means such that the indicia pattern printed can be used to verify the security of said authorization means; and said plurality of indicia patterns including a first graphic pattern and a second graphic pattern, and said second graphic pattern being the color reverse of said first graphic pattern.
Claim 3
Dependent Claim
38 words
System as claimed in claim 1 wherein said indicia pattern printing authorization means comprises: a computer, said computer communicating with said selection means via said communication establishing means, said computer being connected to said indicia pattern storing means.
Claim 4
Dependent Claim
28 words
System as claimed in claim 2 further comprises: a clock/calendar, said clock/calendar being connected said computer such that date and time information can e maintained by said computer.
Claim 5
Dependent Claim
61 words
System as claimed in claim 3 further comprises: a nonvolatile memory in said authorization means, said nonvolatile memory being connected to said computer, said nonvolatile memory being accessible to said selection means for storing information from said selection means such that the indicia pattern selected by said selection means and stored in said authorization means can be accessed by said computer.
Claim 6
Dependent Claim
19 words
System as claimed in claim 4 wherein each of said plurality of indicia patterns has an address assigned thereto.
Claim 7
Dependent Claim
57 words
System as claimed in claim 5 wherein said nonvolatile memory includes: a first block of memory whereat a date can be stored; a second block of memory whereat the address of a currently selected indicia pattern can be stored; and a third block of memory whereat the address of the next selected indicia pattern can be stored.
Claim 8
Dependent Claim
26 words
System as claimed in claim 2 wherein said selection means comprises: a second computer, said second computer communicating with said computer via said communication establishing means.
Claim 9
Dependent Claim
32 words
System as claimed in claim 7 further comprising: means for inputting indicia pattern selection information into said second computer to control the printing of an indicia pattern stored at said authorizing means.
Claim 10
Dependent Claim
21 words
The system of claim 1 wherein the indicia patterns in said plurality of indicia patterns are stored at respective unique locations.
Claim 11
Independent Claim
72 words
A system for detecting unauthorized mail, said system comprising: at least one means for printing postal indicia; and means, remote from said postal indicia printing means, for controlling the selection of a particular postal indicia pattern to be used in printing a graphic pattern so that, when the particular postal indicia pattern, selected is changed only authorized mail will have the changed indicia applied thereto, resulting in the recognition of unauthorized mail.
Claim 12
Independent Claim
72 words
A system for detecting unauthorized mail, said system comprising: at least one means for printing postal indicia; and means, remote from said postal indicia printing means, for controlling the selection of a particular postal indicia pattern to be used in printing a graphic pattern so that, when the particular postal indicia pattern, selected is changed only authorized mail will have the changed indicia applied thereto, resulting in the recognition of unauthorized mail.
Claim 13
Dependent Claim
67 words
System as claimed in claim 10 wherein each said means for printing a postal indicia includes: authorization means for authorizing the printing of a postal indicia, each said authorization means including means for storing a plurality of indicia patterns; and a printer, said printer being controlled by said authorization means and capable of printing a graphic pattern using a postal indicia pattern stored by said authorization means.
Claim 14
Dependent Claim
28 words
System as claimed in claim 11 further comprising: communication establishing means for establishing communication between each said postal indicia printing authorization means and said postal indicia selection means.
Claim 15
Dependent Claim
76 words
System as claimed in claim 12 wherein each said postal indicia printing authorization means further includes: means for assigning an address to each stored postal indicia pattern; and a computer, said computer communicating with said selection means via said communication establishing means, said computer being connected to said indicia pattern storing means and responsive to an address provided by said selection means to provide said graphic pattern using the postal indicia pattern stored at said address.
Claim 16
Dependent Claim
87 words
System as claimed in claim 13 further comprises: a clock/calendar, said clock/calendar being connected to said computer such that date information can be maintained; and a nonvolatile memory, said nonvolatile memory being connected to said computer, said nonvolatile memory being accessible to said selection means such that the indicia pattern selected by said selection means can be accessed by said computer, when said computer detects that the date provided by said clock/calendar is the same as a date provided by said selection means to said nonvolatile memory.
