Abstract

A system and method for secure physiological data acquisition and storage. An identifier of a physiological monitoring patch is obtained by a programming wand, the patch configured to store the identifier within a cryptographic circuit. A password for accessing physiological monitoring data collected using that patch is generated based on at least a portion of the identifier, the password is encrypted using a secret key, and the encrypted password is loaded into the cryptographic circuit. The key is loaded onto a monitor recorder that couples with the patch and obtains the physiological monitoring data using the patch, wherein the monitor recorder offloads the data together with the identifier and the decoded password. The identifier and the password are reported to a server that stores the offloaded physiological monitoring data using the identifier within a secure database and grants access to the data upon receipt of the decoded password.

Claims

1. A system for secure physiological data acquisition and storage, comprising:

a programming wand configured to;

obtain an identifier of a physiological monitoring patch that is configured to store the identifier within a cryptographic circuit on that patch;

generate a password for accessing physiological monitoring data collected using that patch based on at least a portion of the identifier, to encrypt the password using a secret key, and to load the encrypted password into the cryptographic circuit;

load the secret key onto a monitor recorder configured to couple with the patch and to obtain the physiological monitoring data using the patch, wherein the monitor recorder retrieves the identifier and the password from the patch, decodes the password, and offloads the physiological monitoring data together with the identifier and the decoded password; and

report the identifier and the password within the cryptographic circuit to at least one server that is configured to store the offloaded physiological monitoring data using the identifier within a secure database and to grant access to the physiological monitoring data upon receipt of the decoded password from a user.

2. A system according to claim 1, wherein the programming wand is calibrated after a preset number of times of password generation.

3. A system according to claim 1, wherein at least of the identifier is pre-loaded into the cryptographic circuit and the programming wand generates the identifier and loads the identifier into the cryptographic circuit.

4. A system according to claim 1, further comprising:

the at least one server configured to track whether the offloaded physiological monitoring data has been received based on the report.

5. A system according to claim 1, wherein the programming wand wirelessly interfaces with the at least one server, the physiological monitoring patch and the monitor recorder.

6. A system according to claim 1, wherein the password comprises a cryptographic hash of a portion of the identifier, the password further comprising additional data.

7. A system according to claim 1, wherein the additional data comprises pseudorandomly generated numbers.

8. A system according to claim 1, further comprising:

the at least one server is further configured to;

obtain an ECG trace generated based on the physiological monitoring data; and

perform an automated over-read of the ECG trace; and

provide a recommendation based on the automated over-read.

9. A system according to claim 8, wherein the at least one server is further configured to:

identify one or more features of the ECG trace;

compare the identified features to known ECG trace features indicative of one or more conditions; and

generate the recommendation based on the comparison.

10. A system according to claim 1, further comprising:

the at least one server further configured to maintain a website on a data communication network, wherein the at least one server receives from a user device associated with the user the password and the identifier via the website and the at least one server provides the password and the identifier to the user device via the website.

20. A method according to claim 1, further comprising:

maintaining by the at least one server a website on a data communication network, wherein the at least one server receives from a user device associated with the user the password and the identifier via the website and the at least one server provides the password and the identifier to the user device via the website.

11. A method for secure physiological data acquisition and storage, comprising:

obtaining by a programming wand an identifier of a physiological monitoring patch that is configured to store the identifier within a cryptographic circuit on that patch;

generating by the programming wand a password for accessing physiological monitoring data collected using that patch based on at least a portion of the identifier, to encrypt the password using a secret key, and to load the encrypted password into the cryptographic circuit;

loading by the programming wand the secret key onto a monitor recorder configured to couple with the patch and to obtain the physiological monitoring data using the patch, wherein the monitor recorder retrieves the identifier and the password from the patch, decodes the password, and offloads the physiological monitoring data together with the identifier and the decoded password; and

reporting by the programming wand the identifier and the password within the cryptographic circuit to at least one server that is configured to store the offloaded physiological monitoring data using the identifier within a secure database and to grant access to the physiological monitoring data upon receipt of the decoded password from a user.

12. A method according to claim 11, wherein the programming wand is calibrated after a preset number of times of password generation.

13. A method according to claim 11, wherein at least of the identifier is pre-loaded into the cryptographic circuit and the programming wand generates the identifier and loads the identifier into the cryptographic circuit.

14. A method according to claim 11, further comprising:

tracking by the at least one server whether the offloaded physiological monitoring data has been received based on the report.

15. A method according to claim 11, wherein the programming wand wirelessly interfaces with the at least one server, the physiological monitoring patch and the monitor recorder.

16. A method according to claim 11, wherein the password comprises a cryptographic hash of a portion of the identifier, the password further comprising additional data.

17. A method according to claim 11, wherein the additional data comprises pseudorandomly generated numbers.

18. A method according to claim 11, further comprising:

obtaining by the at least one server an ECG trace generated based on the physiological monitoring data; and

performing by the at least one server an automated over-read of the ECG trace; and
