In an example, a non-transitory computer readable storage medium may include instructions that when executed cause a computing device to generate a virtual device representation of an image forming apparatus on a cloud. Further, instructions cause the computing device to update the virtual device representation on the cloud with a configuration state of the image forming apparatus. Furthermore, instructions cause the computing device to analyze the updated virtual device representation to determine whether the image forming apparatus is compliant with a stored policy. Further, instructions cause the computing device to initiate, via the virtual device representation, a remediation action to bring the image forming apparatus to compliance based on the determination.

Compliance determination of image forming apparatuses

Secure code image delivery may include encrypting, using an invariant content encryption key, an invariant portion of a code image for a set of electronic devices to generate an encrypted invariant potion of the code image. A first variant of a variant portion of the code image may be encrypted using a first variant content encryption key to generate a first encrypted variant portion. A second variant of a variant portion of the code image may be encrypted using a second variant content encryption key to generate a second encrypted variant portion. A code image bundle may be generated including the encrypted invariant portion, the first encrypted variant portion, and the second encrypted variant portion.

Secure code image distribution

In an example, a method of encryption is described to include generation of a content encryption key and a key encryption key. In that example, the content encryption key is wrapped based on a key wrap operation using the key encryption key and the wrapped content encryption key is encrypted using a policy encryption key. Further in that example, the policy encryption key is encrypted using a public key corresponding to a print apparatus. In an example, a method of decryption is described. The example method of decryption performs recovery of a policy object using a private key corresponding to a print apparatus. In that example, the policy object includes a wrapped key that is unwrapped using a key encryption key to recover a content encryption key usable to decrypt an encrypted electronic document.

Key encryption key wrapping

A method for an application management service is provided. In the method, a request for a list of available applications is received and a list of available applications is generated based on a whitelist. The list of available applications is transmitted and a selection of an available application is received. A package file corresponding to the selected application is generated and the package file and an installation file corresponding to the selected application are transmitted.

Application management service including package file

Examples associated with printer encryption are described. One example printer includes a data store to store a one-time pad. An encryption module may encrypt a message using the one-time pad. The encryption module also transmits the encrypted message to a trusted device that stores a copy of the one-time pad. A decryption module uses the one-time pad to decrypt a received message form the trusted device. The decryption module also controls the printer to perform an action based on the received message. A refresh module replaces the one-time pad during a service event.

Printer encryption

Examples disclosed herein relate to receiving a request to perform an operation on a document, determining whether the document complies with a plurality of operation policies, and in response to determining that the document complies with the plurality of operation policies, providing a notification that the operation is ready to be performed and digitally signing the document.

Document operation compliance

Examples disclosed herein relate to request authorization and authentication. Examples include to intercept a request from a processing pipeline of a device. The device to determine whether the request is authorized and authentic. The device to generate a cancellation request if the request is not authorized or not authenticated. The device to provide the cancellation request to the processing pipeline of the device.

Cancellation requests

Examples disclosed herein relate to wireless communication of a user identifier and encrypted time-sensitive data. Examples further include wireless communication of an authentication token including a user identifier and encrypted time-sensitive data. Examples further include interaction with a remote authentication service. Examples further include utilization of near field communication (NFC).

Wireless communication of a user identifier and encrypted time-sensitive data

Methods and systems are provided for tracing the source of a printed document. A method may include receiving a print job for printing a page having page content, generating a log of the print job, encoding the log using a mule image to produce a data-bearing halftone image, merging the data-bearing halftone image with the page content, and printing the merged data-bearing halftone image and page content to produce a printed document.

Systems and methods for tracing the source of printed pages

In one embodiment, a first instruction prescribing a setting for a feature is defined. A second instruction prescribing a first action is defined. A third instruction prescribing a second action is defined. It is determined whether the feature is present in a computing device, and if present, whether the feature is set to the setting. The first action is initiated if the feature is present and not set to the setting. The second action is initiated if the feature is not present.

Method and system to secure a computing device

A method of configuring a peripheral device on a network without user intervention includes a server node receiving identification data for identifying the peripheral device on the network and, if the peripheral device is a new device on the network or a driver for the peripheral device is not registered on the server node, the server node self-installing the driver for the peripheral device. As such, newly connected peripheral devices are automatically seen on a network and a driver for the peripheral device is automatically configured on a print server without any user intervention. Additionally, a communication port and queue for the device are also automatically created. Moreover, device configurations are dynamically and automatically updated on the print server for consistent, accurate network information.
