Postage meter with coded graphic information in the indicia
First Claim
Patent Images
1. A system for providing a postal indicia;
- said system comprising;
means for defining a plurality of selected dot-locations in a first array such that, if dots were printed at said dot-locations, said first array would provide postal value validating information in a conventional readable format;
means for transforming said first array into a second array by using a reversible transformation, said second array having dot-locations different from said dot-locations of said first array;
means for printing a selectable array of dots on a mail piece in response to print signals from said transforming means;
means for communicating print signals from said transforming means to said dot printing means, said print signals controlling said dot printing means so that said dot printing means prints transformed postal value validating information on said mailpiece; and
means for accounting for the postal value represented by said first array when said converted postal value validating information is printed, whereby the accounted for postal value can be validated by recovering said first array by an inverse transformation of said second array.

Abstract
A postage meter is disclosed in which security information is encoded in the printed indicia. The information is encoded in a binary format which is transformed in a predetermined manner such that the information is retrievable by a special reader and decoding algorithm for obtaining the original binary format. The transformed indicia may be in one color or maybe multicolored.

10. A method of providing a postal indicia;
- said method comprising the steps of;
defining a plurality of selected dot-locations in a first array such that, if dots were printed at said dot-locations, said first array would provide postal value validating information in a conventional readable format; transforming said first array into a second array by using a reversible transformation, said second array having dot-locations different from said dot-locations of said first array and comprising converted postal value validating information; printing a selectable array of dots corresponding to said second array on a mailpiece; and accounting for the postal value represented by said first array when said converted postal value validating information is printed, whereby the accounted for postal value can be validated by recovering said first array by an inverse transformation of said second array. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
