`

`NEAR FIELD AUTHENTICATION THROUGH COMMUNICATION OF ENCLOSED
`
`CONTENT SOUND WAVES
`
`BACKGROUND OF THE INVENTION
`
`[0001] This application claims priority to U.S. Provisional Application No. 61/595,599, which
`
`was filed February 6, 2012, and which is fully incorporated herein by reference.
`
`1. Field of the Invention
`
`[0002] The present invention relates generally to technology for near field authentication of
`
`users and their computing devices. More specifically, the invention relates to effecting near field
`
`authentication for digital communications by means of encoded sound waves.
`
`2. Description of the Related Art
`
`[0003] The use of a user's electronic device to complete a purchase has been suggested, for
`
`example, utilizing Bluetooth technology or a WiFi Internet connection to transmit the data to the
`
`register. However, such technology requires a transactional device such as a register or ATM
`
`machine to be upgraded and retrofitted with expensive equipment and software to securely
`
`receive the data and authenticate the user's electronic device. Thus, while it may be desirable for
`
`the user, it could be prohibitively expensive for the commercial entity utilizing the transactional
`
`device, especially for small businesses.
`
`[0004] The use of other technology aside from the Internet or the Bluetooth may also require
`
`not only that the transactional device be upgraded and retrofitted, but also that the user's
`
`electronic device be similarly modified. In addition, alternative technology may also have range
`
`limitations which can degrade the user's experience when performing a transaction. For
`
`1
`
`Page 8 of 860
`
`

`

`example, in a conventional near field communication, radio communication 1s utilized to
`
`facilitate transactions. However, the conventional near field communication requires that the
`
`two transacting devices be in extremely close proximity to each other, i.e., within about 4
`
`centimeters from each other to ensure reliable communication. This requirement for close
`
`proximity places a very restrictive limitation on practical applications for near field transactions
`
`in the real world. If one of the transacting devices is a cash register, and the other transacting
`
`device is a customer's mobile phone, the customer would need to extend the phone to within
`
`centimeters of the register and risk dropping the phone. The proximity limitation may also
`
`prevent the user from making further use of the phone while the transaction is taking place and
`
`while the phone is extended away from the customer. For example, should complications in the
`
`transaction arise, or if the user is required to provide a manual input, the customer may not be
`
`able to complete the transaction.
`
`[0005] Another drawback of the conventional near field communication is the lack of security,
`
`despite the close proximity of the two devices.
`
`That is, the conventional near field
`
`communication offers no protection against eavesdropping and can be vulnerable to data
`
`modifications. Needless to say, this 1s undesirable for financial transactions and other
`
`confidential communications.
`
`[0006] Thus, there is a need for improved technology for effecting near field communications.
`
`SUMMARY OF THE INVENTION
`
`[0007] The present invention provides a method for source authentication in network
`
`communications. A source such as a mobile computing device transmits an authentication
`
`request by executing the following salient steps using an audio transceiver: scanning a plurality
`
`2
`
`Page 9 of 860
`
`

`

`of predetermined frequencies for a free frequency, selecting the free frequency from the plurality
`
`of predetermined frequencies, generating a periodic enclosed content message, encoding a carrier
`
`wave with the periodic enclosed content message, and transmitting the modulated carrier wave at
`
`the free frequency. The audio transceiver, in one example, may be a mobile phone having both a
`
`speaker and a microphone.
`
`[0008] The periodic enclosed content message includes an enclosed content message at each
`
`period. The enclosed content message comprises a beginning indication, a content, and an
`
`ending indication. The beginning indication indicates when the enclosed content message
`
`begins, while the ending indication indicates when the enclosed content ends. This allows for
`
`verification that the enclosed content message is completely instead of partially received.
`
`Furthermore, the content can include biometric data or device identification data, or both, which
`
`can be used to authenticate the user or the mobile computing device. Furthermore, the content
`
`may also include financial information for the user, or other data which might be used for
`
`gaining access to a secure network for facilitating a transaction once the user or the mobile
`
`computing device, or both, have been authenticated.
`
`[0009]
`
`In another embodiment, the present invention includes a computer readable medium
`
`useful in association with an audio transceiving computing device that includes one or more
`
`processors and a memory, the computer readable medium including instructions configured to
`
`cause the audio transceiving computing device, by execution of the instructions in the one or
`
`more processors from the memory, to request authentication by executing the salient steps.
`
`[0010]
`
`In another embodiment, the present invention includes a mobile computer system
`
`including at least one processor, a computer readable medium that is operatively coupled to the
`
`3
`
`Page 10 of 860
`
`

`

`processor, and a transmission logic that (i) executes in the processor from the computer readable
`
`medium and (ii) when executed by the processor causes the mobile computer system to request
`
`authentication by executing the salient steps.
`
`[OOll] The invention also provides a method for receiving an authentication request using an
`
`audio or microphone input of a receiving computing device by executing the following second
`
`set of salient steps: scanning a plurality of predetermined frequencies to detect a signal using the
`
`microphone input, verifying, responsive to detecting the signal, that the signal includes at least
`
`one enclosed content message, and extracting a content from the enclosed content message.
`
`[0012] Another embodiment of the invention comprises a computer readable medium useful
`
`in association with an audio receiving computing device that includes one or more processors, an
`
`audio or microphone input, and a memory, the computer readable medium including computer
`
`instructions which are configured to cause the audio receiving computing device, by execution of
`
`the computer instructions in the one or more processors from the memory, to receive an
`
`authentication request by execution of the second set of salient steps.
`
`[0013]
`
`In another embodiment, a present invention is a computer system including at least one
`
`processor, an audio input that is operatively coupled to the processor, a computer readable
`
`medium that is operatively coupled to the processor, and a near field authentication receiver
`
`logic that (i) executes in the processor from the computer readable medium and (ii) when
`
`executed by the processor causes the computer system to receive an authentication request via
`
`the audio input by execution of the second set of salient steps.
`

`
`DETAILED DESCRIPTION
`
`[0025] The present invention relates to a method and system for near field authentication of
`
`users and computing devices using sound waves. Such users and computing devices may be
`
`referred to collectively herein as "sources". Authenticating a source according to the present
`
`invention may involve authenticating only a user, only a computing device, or both a user and a
`
`computing device.
`
`[0026] As seen in FIG. 1, a system 100 for authenticating sources using sounds waves can
`
`6
`
`Page 13 of 860
`
`

`

`include, for example, an audio transceiving computing device 102, and an audio rece1vmg
`
`computing device 104. The audio transceiving computing device 102 can transmit data to the
`
`audio receiving computing device 104 as a modulated carrier wave 106. The modulated carrier
`
`wave 106 can be, for example, a sound wave. Sound waves can transmit information accurately
`
`over a very short distance (near field communications) using inexpensive equipment.
`
`In
`
`different embodiments, the sound wave can have a frequency that is substantially below, within,
`
`or above the audible frequencies, such as below 20 Hz, between 20 Hz and 20 kHz, or above 20
`
`kHz. For example, the sound wave could be an ultrasonic wave.
`
`[0027] The audio transceiver computing device 102 can be, for example, a mobile phone, a
`
`personal digital assistant, a tablet, a laptop, a music player, or any other device having a
`
`processor operatively coupled to memory and capable of transmitting the modulated carrier wave
`
`106 responsive to operation of the processor. As seen in FIG. 2, the audio transceiver computing
`
`device 102 can include, for example one or more microprocessors, which are collectively shown
`
`as CPU 202. The audio transceiver computing device 102 also includes, for example, a memory
`
`204, an interconnect 206, an input 208, an output 210, and/or a network access circuitry 212.
`
`The CPU 202 can retrieve data and/or instructions from the memory 204 and execute the
`
`retrieved instructions. The memory 204 can include generally any computer-readable medium
`
`including, for example, persistent memory such as magnetic and/or optical disks, ROM, and
`
`PROM and volatile memory such as RAM.
`
`[0028] The CPU 202 and the memory 204 are connected to one another through the
`
`interconnect 206, which is a bus in this illustrative embodiment. The interconnect 206 connects
`
`the CPU 202 and the memory 204 to the input devices 208, the output devices 210, and the
`
`network access circuitry 212. The input devices 208 can include, for example, a keyboard, a
`
`7
`
`Page 14 of 860
`
`

`

`keypad, a touch-sensitive screen, a mouse, a microphone, and/or one or more cameras. The
`
`output devices 210 can include, for example, a display - such as a liquid crystal display (LCD) -
`
`and/or one or more speakers. The network access circuitry 212 sends and receives data through
`
`computer networks such an intranet or the Internet.
`
`[0029] A number of components of the audio transceiver computing device 102 are stored in
`
`the memory 204. In particular, a near field authentication transceiver logic 214 is part of one or
`
`more computer processes executed within the CPU 202 from the memory 204 in this illustrative
`
`embodiment, but can also be implemented using digital logic circuitry. As used herein, "logic"
`
`refers to (i) logic implemented as computer instructions and/or data within one or more computer
`
`processes and/or (ii) logic implemented in electronic circuitry.
`
`[0030]
`
`In an embodiment, the near field authentication transceiver logic 214 is executable
`
`software stored within the memory 204. For example, when the audio transmitting computing
`
`device 102 receives a request from the user to transmit the modulated carrier wave 106, the audio
`
`transceiver computing device 102 executes the near field authentication transceiver logic 214 to
`
`transmit the modulated carrier wave 106 to the audio receiving computing device 104. As
`
`previously noted the modulate carrier wave 106 can be an analog signal, such as a sound signal.
`
`Advantageously, an analog signal has an infinite amount of signal resolution. Furthermore, the
`
`use of sound signals in
