Abstract

A system and method for providing a unique signature for proprietary data. The proprietary data may be transmitted to multiple trusted parties. Each of the trusted parties will have proprietary data with a unique signature to that trusted party. The signature allows a user to determine the source of the proprietary data breach via the signature.

First claim

What is claimed is:

1 . A method of identifying a source of data, comprising:
receiving a request for proprietary data of a first party from a second party; generating a set of identification data unique to the second party, wherein the set of identification data is a high frequency fingerprint signal generated as a function of a time stamp of a receiver ID of a transmission signal to the second party; operating a treatment device to provide treatment to the first party, wherein the operation of the treatment device generates an analog signal, wherein the analog signal identifies the treatment device; adding the analog signal identifying the treatment device to the set of identification data; embedding the set of identification data into the proprietary data, wherein the identification data is indistinguishable from the proprietary data; and sending the proprietary data with the embedded identification data to the second party via the transmission signal to the second party.

2 . The method of claim 1 , further comprising:
determining an unauthorized transfer of the proprietary data to a third party; and retrieving the identification data from the propriety data from the third party to determine the source of the proprietary data.

3 . The method of claim 1 , further comprising:
maintaining a library of sets of identification data, each of the sets of identification data being unique to a party distinct from the first party, wherein the set of identification data is stored in the library.

4 . The method of claim 1 , wherein a period of the high frequency signal is proportional to the receiver ID and the phase of the timestamp of transmission.

5 . The method of claim 1 , wherein the proprietary data is organized in kernels, and wherein the identification data includes convolutional operators with the values of the kernel and size of the kernel specific to the identification data.

6 . The method of claim 1 , wherein the identification data includes discrete data values, wherein the identification data is embedded at known locations in the proprietary data.

7 . The method of claim 1 , further comprising converting the proprietary data to a digital format after embedding the set of identification data.

8 . The method of claim 1 , wherein the proprietary data is a physiological waveform measured from the first party.

9 . The method of claim 1 , wherein the embedding occurs on the treatment device.

10 . The method of claim 9 , wherein the treatment device is a respiratory therapy device including a microphone and a motor driving an air pressure generator to provide air flow therapy to the first party, and wherein the analog signal is one of a microphone signal sensing motor noise from the motor or a pressure sensor signal sensing air flow generated by the air pressure generator while the respiratory therapy device provides air flow therapy to the first party.

11 . A system to embed identification data to track proprietary data supplied by a first party, the system comprising:
a storage device storing proprietary data belonging to the first party; a processor that executes computer instructions to:
generate identification data unique to the second party, wherein the set of identification data is a high frequency fingerprint signal generated as a function of a time stamp of a receiver ID of a transmission signal to the second party;
receive device identification data identifying a treatment device providing treatment to the first party, wherein the device identification data includes an analog signal generated by the operation of the treatment device, the analog signal identifying the treatment device;
add the device identification data identifying the respiratory therapy device to the identification data;
embed the identification data to the proprietary data, wherein the identification data is indistinguishable from the proprietary data; and
send the combined proprietary and identification data in the transmission signal to the second party via a data transmitter.

12 . The system of claim 11 , wherein the processor further executes computer instructions to retrieve the identification data from the propriety data from the third party to determine the source of the proprietary data when an unauthorized transfer of the proprietary data to a third party occurs.

13 . The system of claim 11 , further comprising a library of sets of identification data, each of the sets of identification data being unique to a party distinct from the first party, wherein the set of identification data is stored in the library.

14 . The system of claim 11 , further comprising an analog to digital converter operable to convert the proprietary data to a digital format after embedding the set of identification data.

15 . The system of claim 11 , wherein the fingerprint engine is part of the treatment device.

16 . The system of claim 11 , wherein the treatment device includes a sensor monitoring an operational function of the treatment device when the treatment device provides treatment to the first party.

17 . The system of claim 16 , wherein the treatment device is a respiratory therapy device including a microphone and a motor driving an air pressure generator to provide air flow therapy to the first party, and the sensor is one of the microphone sensing motor noise from the motor or a pressure sensor sensing air flow generated by the air pressure generator while of the respiratory therapy device provides air flow therapy to the first party.

18 . The system of claim 11 , wherein the proprietary data is breath related data from breathing sensed from the first party.

19 . A non-transitory computer program product comprising instructions which, when executed by a computer, cause the computer to carry out:
receiving a request for proprietary data of a first party from a second party; generating a set of identification data unique to the second party, wherein the set of identification data is a high frequency fingerprint signal generated as a function of a time stamp of a receiver ID of a transmission signal to the second party; receiving device identification data identifying a treatment device providing treatment to the first party, wherein the operation of the treatment device generates an analog signal identifying the treatment device; adding the device identification data identifying the respiratory therapy device to the identification data; embedding the set of identification data into the proprietary data, wherein the identification data is indistinguishable from the proprietary data; and sending the proprietary data with the embedded identification data to the second party via the transmission signal.
