Abstract: A method for secure physiological data acquisition and storage is provided. An identifier of a physiological monitoring device that is configured to store the identifier within a cryptographic circuit is obtained by a programming wand. A password for accessing physiological monitoring data collected using that device is generated based on at least a portion of the identifier. The password is encrypted using a secret key, and password is loaded into the cryptographic circuit. The secret key is loaded into a monitor recorder, wherein the monitor recorder retrieves the identifier and the password from the device, decodes the password, and offloads the physiological monitoring data together with the identifier and the decoded password. The identifier and the password are reported to at least one server. The offloaded physiological monitoring data is stored using the identifier. Access to the data is granted upon receipt of the decoded password from a user.

Abstract: The electrode patch can store an identifier, such as a serial number, and a password associated with the identifier. The password can include a cryptographic hash of the identifier. The password and the identifier are coupled to the data collected using the patch and the data can be stored as electronic medical records (EMR) in a database based on the identifier. A patient or another authorized party can access the data using the identifier and the password. The EMRs can also include results of analysis of data received from the monitor, such as an automated over-read of an ECG trace based on the received data.
