Abstract (en)
[origin: EP0660270A2] An arrangement for generating and checking a security imprint consists of a franking machine with a microprocessor in a control unit (6), which microprocessor performs an encoding in the form of marking pixel image data and which inserts these into the remaining fixed and variable pixel image data during the printing operation. The method comprises steps for forming a series of marking symbols from an encoded combination number which is composed of at least one first number (the sum of all the postage values since the last reloading date), a third number (postage value) and a fourth number (from the serial number), and makes it possible for a postal authority to check the security imprint, manipulations being detected by the inclusion of further data stored and/or computed at the data centre. A checking arrangement (29) has a marking reader (24) consisting of a CCD line-scan camera (241), D/A converter (243), comparator (242) and encoder (244) which are connected to an input means (25) via an input/output unit (245). In order to evaluate marking data by means of a computer (26), storage means (28) and output means (27), the input means (25) is connected to the data centre. <IMAGE>
