Abstract: Methods and apparatus to protect sensitive information on media processing devices are disclosed. An example media processing device includes a processing engine configured to process a media processing instruction received at the media processing device, wherein the media processing instruction includes a command and data to cause a component of the media processing device to perform a function; and a data protector configured to determine whether the command is a data protection command; and when the command is the data protection command, modify the function to provide protection to the data.

Abstract: In some implementations, a device may transmit, to an authentication server, a certificate signing request (CSR) based on a private key stored on a data logger, wherein the data logger is integrated with a sensor within the device. The device may receive, via the data logger and from the authentication server, a signed device certificate based on the CSR. Additionally, the device may receive, via the data logger and from the authentication server, a signed owner certificate associated with a controller. The device may receive, via the data logger and from the controller, a command signed using the owner certificate. Accordingly, the device may store, in the data logger, measurements from the sensor based on the command. The device may generate a data structure including the stored measurements, wherein the data structure is signed using the signed device certificate. The device may transmit, to the authentication server, the data structure.

Abstract: An example disclosed method for use in a device configured to communicate using digital certificates includes, in response to a request, receiving a digital certificate for use in secure communications between the device and another device; evaluating, using a logic circuit, the digital certificate to determine a validity of the digital certificate; when the digital certificate is valid, allowing use of the digital certificate by the device; and when the digital certificate is invalid, preventing use of the digital certificate by the device.

Abstract: A disclosed example is a server residing on a first network. The server has an observer. The observer receives observational data from a media processing device residing on a second network via a first persistent connection between the media processing device and the server. The observer provides, via the first persistent connection, a configuration file to the media processing device that defines a type of the observational data to be collected by the media processing device. The observer is prevented from communicating an operational instruction to the media processing device. The operational instruction is to control media processing hardware of the media processing device.
