Abstract: A message control system particularly useful for postage meters of the type having bit-map printers includes encryption means for generating a code in a postage meter based on meter information and the desired information to be included in the message to be printed. The message and other data is furnished to a data center which then generates an authorization code to be furnished to the postage meter. When there is a match between the authorization and internal code, the message can be stored in the postage meter for printing. The messages may also reside in a slogan box which must remain connected to the meter in order for the slogan to be printed.

Abstract: A deterrent to counterfeiting of indicias on mailpieces is provided in a method and apparatus for implementing the printing of the indicia using a customized printhead or customized printer drivers such that the dots of the bit-mapped printing are produced by the printer in unevenly spaced rows or columns. The dot size may also be varied in accordance with data from the meter, printed value, variable data such as the date, and forensic data suitably encrypted. When the indicia is scanned, the variations are readily detectable and the information is easily extracted by Postal Authorities.

Abstract: A system for controlling the validity of printing of indicias on mailpieces from a potentially large number of users of postage meters includes apparatus disposed in each said postage meter for generating a code and for printing the code on each mailpiece. The code is an encrypted code representative of the postage meter apparatus printing the indicia and other information uniquely determinative of the legitimacy of postage on the mailpieces. The keys for the code generating apparatus are changed to change its code generation at predetermined time intervals in each of the meters. A security center includes apparatus for maintaining a security code database and for keeping track of the keys for generating security codes in correspondence with the changes in each generating apparatus and the information printed on the mailpiece by the postage meter apparatus for comparison with the code printed on the mailpiece.

Abstract: A system for obtaining recharge codes for one or more postage meters. The system includes a conventional microcomputer; including a keyboard and display, and disk drive, which is connected through a modem to a remote data processing center. The center provides codes which may be used to recharge postage meters, i.e., reset the meters so that they may continue printing postage. The system includes a data bank of information relating to each of the postage meters, including identification codes for each of the meters. A user enters information, including a control sum, for each meter and the system combines it with other information stored in the data bank to form messages. The system then enters into transactions with the remote data processing center to obtain recharge codes for each of the meters, which are then displayed for entry into the meters. In another embodiment the system may communicate directly with each meter through a local communications network.
