Abstract
Method and apparatus for sending, receiving, and displaying custom coded textual and/or graphic data via an alphanumeric paging system wherein source data in binary form is encrypted with a designated code and then further converted to an alphanumeric code for transmission via the paging system; a paging receiver with storage capability used in combination with a computer then receives the transmitted data and downloads the alphanumeric code data for reconversion and decryption to binary data and subsequent display of the text and/or graphic data.
Claims20
A method for transmitting selected data that is encrypted with a custom code from a source position to a remote position, comprising:
- generating said selected data as digital binary data at the source;
- encrypting said binary data in accordance with the custom code;
- converting the custom code encrypted data to alphanumeric code data and dividing into at least one successive sub-files, each of preselected maximum message size;
- transmitting the divided, encrypted alphanumeric code data via a paging switch;
- receiving the encrypted alphanumeric code data via paging receiver at the remote position;
- downloading the encrypted alphanumeric code data to a personal computer which recombines the at least one sub-files;
- decoding the encrypted alphanumeric code data to encrypted binary data;
- decrypting the encrypted binary data to generate binary data;
- and
- displaying said binary data in original selected data form.
A method for transmitting paging data that is encrypted with a selected custom code from a source to a remote position, comprising:
- deriving said paging data at the source as binary data;
- encrypting the binary data in accordance with the custom code;
- encoding the encrypted binary data to ASCII code data;
- transmitting the ASCII code data via an alphanumeric paging system;
- receiving the ASCII code data at the remote position;
- downloading the ASCII code data to a personal computer which decodes to the encrypted binary data;
- and
- decrypting the encrypted binary data for output indication of the paging data.
A paging system for transmitting selected data encrypted with a custom code to a remote location, comprising:
- means for deriving the selected data in binary signal form;
- means for encrypting the binary signal form to custom coded binary signals;
- means for translating the custom coded binary signals to ASCII code data;
- a paging switch for receiving the ASCII code data and transmitting the data;
- a paging receiver for receiving the ASCII code data and storing for subsequent download of data;
- means receiving the download data and retranslating the ASCII code data to said custom coded binary signals;
- means for decrypting said custom coded binary signals to generate binary signal data;
- and
- means for processing the binary signal data to provide output indication of the selected data.
