Abstract
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.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
137 words
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.
Claim 2
Independent Claim
137 words
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.

Claim 5
Dependent Claim
34 words
A method as set forth in claim 1 wherein the step of downloading further includes: recombining the encrypted alphanumeric code data sub-files in the personal computer thereby to reconstruct the total encrypted selected data.
Claim 6
Dependent Claim
33 words
A method as set forth in claim 4 wherein said step of transmitting comprises: applying the encrypted alphanumeric code data through a modem to the paging switch to transmit the alphanumeric code data.
Claim 7
Dependent Claim
35 words

Independent Claim
99 words
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.
Claim 9
Independent Claim
99 words
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.
Claim 10
Dependent Claim
31 words
