`telephone call to agree on When to “turn on the fax machine”,
`priority, re-transmission on “busy”, undeliverable, etc.
`
`This invention relates to connecting stand alone fax
`machines for transmitting/receiving facsimile images over
`remote networks and more particularly to a method and appa
`ratus for attaching common class 1, 2, and 3 fax image data to
`MIME compliant e-mail for transmitting/receiving conven
`tional Class 1, 2, and 3 fax images and for receiving other
`electronic data on common class 1, 2, and 3 fax machines over
`global area netWorks of Which the “Intemet” is one example.
`
`BACKGROUND OF INVENTION
`
`In recent years the so called “Fax” machine has become a
`common device in businesses both large and small and also in
`many homes. In 1966 the so called Group or Class 1 standards
`Where adopted and With that came the start of the present
`popularity of the device. Although it took about six minutes to
`transmit a single page and the resolution Was poor it Was a big
`improvement over mail especially for international commu
`nications. In 1978 Class 2 standards appeared folloWed in
`1980 by the Class 3, Which machines Were much faster and
`had much better resolution. These latter machines take about
`30 seconds to transmit a page of text.
`Ubiquitous physical stand alone fax machines remain the
`norm today for every day transmission of Written documents
`and images but lack the ability to directly connect to and
`send/receive such documents across internet global area net
`Works. The term “internet global area networks” is used
`herein in the generic sense of interconnected regional,
`national and international netWorks over Which information
`in electronic form is transmitted. The “Intemet” currently is
`perhaps the best knoWn of these netWorks.
`
`PRIOR ART
`
`While fax machines are noW thought of as universal all
`class 1, 2, and 3 machines are currently direct telephonic
`connection devices and as such acquire toll charges for their
`use over the telephone companies sWitches. This of course
`means that the sender must pay intrastate and interstate long
`distance toll charges for the time it takes to transmit the
`desired communication, Which in a busy of?ce can amount to
`hundreds of dollars a month and in an international company
`to many thousands of dollars. Todays common fax machines
`cannot communicate directly over internet global area net
`Works nor can they receive electronic mail. Security of inter
`net global area netWorks communications also is currently
`dif?cult to achieve and ensure. The ability to de?nitively
`verify the identity of the sender of a fax transmission is often
`dif?cult if not impossible to achieve. Also if absolute security
`is required expensive encryption/decryption devices must be
`employed to communicate by fax over public telephone lines.
`Secure private lines can be used but are expensive and limited
`in the addresses that can be accessed.
`The ability to choose When to receive fax transmissions and
`to decide Which ones to print and Which ones to discard is not
`readily available to the average fax user. Negotiating fax
`transmissions, particularly on a multi use single telephone
`line, often requires ancillary communications to achieve; ie
`
`OBJECTS AND SUMMARY OF INVENTION
`
`Accordingly it is an object of the present invention to
`provide a method and apparatus that overcomes these limita
`tions of the prior art.
`It is another object of the present invention to provide a
`method and apparatus for transmitting/receiving class 1, 2,
`and 3 fax images over internet global area netWorks.
`It is another object of the present invention to provide a
`method and apparatus for transmitting/receiving standard
`class 1, 2, and 3 fax images over the Internet.
`It is another object of the present invention to provide a
`method and apparatus for transmitting/receiving class 1, 2,
`and 3 fax images in a highly secure and private manner.
`It is a further object of the present invention to provide an
`economical device that can be easily connected to present
`class 1, 2, and 3 fax machines and that Will enable them to
`communicate over internet global area netWorks.
`It is a further object of the present invention to provide an
`economical device that can be easily connected to present
`class 1, 2, and 3 fax machines that provides a built in elec
`tronic mail agent and means for converting the fax image data
`stream to e-mail SMTF/MIME/MOSS format for transmis
`sion/reception over the internet global area netWorks.
`It is a further object of the present invention to provide a
`device that can easily be connected to class 1, 2, and 3 fax
`machines that alloWs e-mail to be printed out thereon.
`It is a still further object of the present invention to provide
`a device that can be easily connected to standard class 1, 2,
`and 3 fax machines to convert the fax image data stream to
`MIME enabled e-mail format for transmission/reception With
`similarly equipped fax machines and e-mail capable com
`puter terminals over the Internet.
`These and other and further objects of the present invention
`are accomplished in one embodiment of the present invention
`by a device having signal recognition means, a data store and
`forWard buffer, conversion means, an electronic mail agent,
`management and output means, encryption/decryption
`means, and softWare for accomplishing the desired transmis
`sion of fax images over internet global area netWorks.

`electronic mail agent server 20 such as a commercial or public
`server Which in turn is connected to or resident on the internet
`global area netWork 12. A remote electronic mail agent server
`22 resident on the internet global area netWorks 12 at a remote
`location is connected over a POTS line 24 to another device
`16 Which in turn is connected to a remote fax machine 26 by
`another line 15. Fax machines 14 and 26 can be any class 1, 2,
`or 3 fax machines currently available on the market and are
`connected to the usual domestic poWer source at 28. Devices
`16 have their oWn poWer supplies 30 Which convert the usual
`AC poWer to the appropriate voltages to poWer the various
`components Within the devices 16 as Will be described in
`detail herein.
`FIG. 2 shoWs in block diagram form the system of FIG. 1
`along With a privately accessible address book of public
`encryption keys 32 Which may be accessed by direct dial up
`phone lines 34. In addition to the remote device 16 and fax
`machine 26 the remote agent server 22 may be connected by
`POTS line 36 to a modem 38 and computer 40 Which can store
`and display the data stream available in the agent server 22.
`Referring noW to FIG. 3 the signal manipulation device is
`shoWn in detailed block diagram form. As Will be described
`herein device 16 takes the fax image data stream and converts
`it into an e-mail compatible format for transmission over the
`internet global area netWork 12. Device 16 Will henceforth be
`called ‘ecom’ 16. This, along With the necessary management
`of the entire procedure, is accomplished in one embodiment
`by the device of FIG. 3.
`When fax machine 14 initiates a call the ecom 16 responds
`as if it Were the remote fax machine called by fax 14. The
`usual handshake and identi?cation information is exchanged
`by recognition box 42 and When con?rmed passed to the store
`and forWard buffer 44. From here the data stream Will be sent
`to the various other functions Within ecom 16 in accordance
`With the instructions in box 42. Data compression/decom
`pression is usually accomplished While the data is in buffer 44
`also. Next the native facsimile data stream is converted into
`electronic mail (e-mail) format in box 46. Image compression
`including J PEG, GIF, and TIFF; audio and video compression
`such as MPEG; and e-mail extender such as MIME/MOSS
`are also accomplished, at this time. If encryption is indicated
`the converted data stream is directed to encryption/decryption
`block 48 for coding as Will be described later. If coding is not
`indicated the data stream is passed to electronic mail agent 50
`Which performs store/send/user/passWord identi?cation
`functions as necessary to interface With the selected server 20.
`Electronic mail agent 50 preferably is a commercial mail
`agent but it may be any public or private mail agent. In one
`embodiment both commercial and public electronic mail
`agents are provided.
`As may be seen in FIGS. 8 and 9, a keypad 52 is provided
`to input special instructions, address information and status
`information such as “e-mail Waiting” and the like. From box
`52 the converted and formatted data stream is passed to box
`54 for ?nal mail agent server phone numbers, send/receive
`and connect signal functions. The data stream is then ready to
`be sent dynamically to the selected local agent server 20
`resident on the internet global area netWorks 12 over a POTS
`line 18.
`From this point on the data stream is under the control of
`the usual global netWork servers, managers, and providers
`until it reaches its destination at the remote ecom 16 con
`nected to the addressed remote fax machine 26. The How
`diagram shoWn in FIG. 4 illustrates this sequence of opera
`tions.
`While I have shoWn the ecom 16 connected to the server 20
`by a telephone line any transport mechanism can be used to

`transmit the data stream to/from the internet global area net
`Work server 20 such as cellular, satellite, microWave and
`broadcast.
`In the event encryption is indicated the converted data
`stream is routed through box 48 from box 46 and then to
`electronic mail agent 50. The How diagram in FIG. 5 illus
`trates this sequence.
`Referring noW to FIGS. 2 & 6 there is shoWn another
`embodiment of the present invention Where the local fax
`machine 14 can transmit an image to a remote computer. In
`this con?guration since the converted data stream received at
`server 22 is in e-mail format it can be sent directly to a
`computer 40 Which With the proper modem can store, display
`and print out the transmitted document.
`FIG. 7 is a How diagram of a still further embodiment of the
`present invention in Which it is only desired to encrypt a
`conventional fax transmission. In this con?guration the ecom
`16 processes, and encrypts the data stream but then bypasses
`the agent and sends the signal directly to the POTS line Which
`is also connected to the remote ecom 16 and fax machine 26.
`The data stream is received by the remote ecom Which
`decrypts it and prints it out on the remote fax machine.
`FIG. 8 is a schematic block diagram of the ecom 16 shoW
`ing the general layout and interconnection of the various
`components making up the ecom 16. Lines 15 from the physi
`cal stand alone fax machines 14 and 26 are connected to the
`bus 60 in ecom 16. Bus 60 connects all of the components
`together and to the output POTS lines 18 or 24. Modems 62
`and 84 serve as input and output modems during transmission
`and the reverse for reception of data. CPU 72 contains the
`instruction sets needed to run the ecom and may be a 386DX/
`33MHZ chip. ASIC chip 64 along With EPROM 68 contain
`the softWare instruction sets for the CPU and the TCP/IP,
`SMTP,MTA protocols and the algorithms for attaching the
`class 1, 2, and 3 fax data stream (Phase Cll data) to MIME
`enabled commercial and/or public electronic mail format.
`EPROM 70 is a mail user agent that contains the commercial
`and/or public mail boxes and EPROM 66 is a ?ash EPROM
`containing the encryption/ decryption algorithms. RAMS 74,
`76, and 78 provide for storing and forWarding data to the
`ASIC and CPU chips and to the attached facsimile and e-mail
`data streams. D/A block 88 is an analog to digital converter
`Which encapsulates the fax image data stream into MIME
`e-mail digital format and vice versa. Block 80 provides com
`pression/decompression operations on the data streams.
`USART block 90 is a universal asynchronous transmitter/
`receiver chip for transferring the keypad 52 entered com
`mands to the foregoing components and to the displays 94 and
`96. Which indicate system status. A voice chip 92 and speaker
`98 and auxiliary port 102 may also be provided. The fax
`machine and POTS lines are connected through standard
`R11 1 connectors. The poWer supply 30, Which may be housed
`Within ecom 16 if desired as shoWn in FIG. 8, takes standard
`AC poWer and converts it to the necessary line tone/ring
`generator, DC and other voltages necessary for running the
`ecom 16. An on/off sWitch 100 turns the ecom on and off.
`Referring noW to FIG. 9 the keypad 52 has the usual
`QWERTY keyboard and the usual numerals 1 through 0. In
`addition there are provided special function keys that com
`bine several key stroke commands of the usual computer into
`single stroke keys for the particular functions. Thus the @
`key, the Dot key, for addressing e-mail; COM for commercial,
`NET for netWork, EDU for education, ORG for other orga
`niZations, MIL for military, and GOV for government, pro
`vide quick accurate domain addressing; SEND MAIL, GET

`MAIL, PREVIEW MAIL, DELETE MAIL, PRINT, for the
`obvious operations and PRIVATE for coding transmissions
`are also provided.
`To send a fax from a local to a remote fax machine over the
`internet global area netWorks according to the present inven
`tion the folloWing dynamic sequence takes place:
`The user inputs the e-mail address of the selected remote
`fax machine via the keypad 52. The LCD 94 displays, via the
`USART 90 this input. The user then depresses the SEND
`MAIL key. If native fax data is present in the memory buffer
`the CPU instruction set begins conversion of the data together
`With the ASIC 64 into e-mail Mail User Agent format. If no
`native fax data is present in memory then the LCD94 displays
`a “Waiting for fax” default message. The modi?ed data is
`compressed via box 80 and the CPU checks to see if encryp
`tion is indicated. If encryption is required the CPU instructs
`the ASIC 64 With EPROM 70 to perform the encryption and
`stores the result in memory. The LCD 94 then indicates “mail
`is ready for delivery”. The user then presses SEND MAIL
`again and the CPU retrieves the e-mail server telephone num
`ber stored in EPROM or RAM and initialiZes modem 84,
`converter 88 and DSP 82 and via the LTG 86 dials the proper
`phone number. After the proper return codes and hand shake
`is completed With the e-mail server the CPU sends the e-mail
`stored in the buffer and clears the buffer. Upon receipt of
`proper server return codes that the mes sage has been received
`the CPU instructs the modem 84 to close and the ecom is
`returned to ready for further tra?ic.
`At the receiving end after transitting the internet global
`area netWorks the data manipulation sequence in the remote
`ecom is essentially the reverse of that just described. In addi
`tion a user of the ecom can query its mail server to see if there
`is fax e-mail Waiting that could not be delivered previously.
`Also e-mail other than converted fax image data can be
`printed out on a fax machine attached to an ecom device. The
`user presses GET MAIL Which displays the command on
`LCD 94 and then the CPU instructs the appropriate EPROM
`to retrieve the appropriate server phone number and to dial
`same via the modem 86. After proper identi?cation and hand
`shake if there is mail the server Will send it to the MUA
`40
`EPROM 70 and the CPU Will then send it to memory buffer
`and terminate connection to the server. The usual “previeW
`mail” capability can also be included in ecom 16 if desired.

`this invention and its application in practical use, it should be
`understood that they are not intended to be exhaustive or to be
`limiting of the invention. On the contrary, these illustrations
`and explanations herein are given in order to acquaint others
