Disclosed are systems and methods that provide authentication for printed and/or electronic versions of a document through the use of a document authentication device in the form of a computational tag configured for short-range wireless communication only. This document authentication device receives authentication information for a document from a computerized device over a wireless communication link and uses this authentication information to generate encoded data to be embedded in the document in order to establish the authenticity of the document by functioning as an imprimatur. Specifically, when embedded in the document, this encoded data can add a visible feature or non-visible feature that, upon inspection, establishes the authenticity of an electronic version of the document and/or can add a printable feature, which will be readable off a surface of a printed version of the document to establish the authenticity of that printed version.

Systems and methods for verifying physical proximity to a network device are provided. The method includes acquiring a tag identifier from a tag fixed in, on, or proximal to a network device, using a computing device. The tag is configured to be read and written to by electronic communication with the computing device, when the computing device is disposed in proximity to the tag. The method further includes transmitting data indicative of the tag identifier to a server, and receiving an authorization confirmation from the server. The method also includes rewriting the tag so as to replace the tag identifier with a new tag identifier, using the computing device, and performing one or more operations with the network device after receiving the authorization.

The present invention generally relates to systems and methods for establishing trusted, secure communications from a mobile device, such as a smart phone, to an immobile device, such as a multi-function device. The disclosed techniques can include the immobile device displaying a pattern that encodes a cryptographic key. The mobile device can obtain an image of the pattern and decode it to obtain the cryptographic key. Because the mobile device obtained the image within its line-of-sight, for example, it can be assured that it communicated with the immobile device, and only the immobile device. The mobile device and the immobile device can use the cryptographic key to secure further communications.

A method for establishing a network connection between a mobile electronic device and a target network device includes establishing a short-range communications link between the mobile electronic device and the target network device. The method may also include, by a processor, executing an application that causes the processor to receive network device information from the target network device, via the short-range communications link, use the identifier associated with the target network device to identify a network to which the target network device is connected, use a transmitter component of the mobile electronic device to establish the network connection between the mobile electronic device and the target network device, via the identified network, and cause the transmitter component to send a communication to the target network device, via the identified network. The network device information comprises an identifier associated with the target network device.

System and method for network access discovery

A first printer acquires a first network address from an external server using unicast (non-broadcast) transmissions. Then, second printers and an external computerized device also acquire the first network address from the external server, similarly using unicast transmissions. The second printers contact (e.g., say 'hello' to) the first printer using a peer-to-peer network. The external computerized device contacts (again using unicast transmissions) the first printer using the first network address to cause the first printer to transmit a list of the second printers that have contacted the first printer to the external computerized device. The external computerized device then contacts (again using unicast transmissions) the second printers using the list of contacted printers (which includes network address information of the second printers) to allow the external computerized device to configure the second printers.

Network discovery using unicast communications

The present invention generally relates to systems and methods for ensuring proximity between a first, e.g., mobile device, such as a smart phone, and a second, e.g., immobile device, such as a multi-function device. The invention can include the second device displaying a pattern that represents a series of movements, which a user of the first device can mimic. The first device can thus prove that it and its user are in proximity to the second device.

Systems and methods for establishing mobile user proximity via active mimicry

Systems and methods are disclosed for overriding a print ticket. An electronic document for printing on a target image output device is identified on a portable computing device. Printing and finishing instructions are selected, based on capabilities of the target device. A request to convert the electronic document to a printable format is transmitted to a separate document conversion service. The electronic document in the form of a printable document having a generic print ticket is received from the document conversion service. The generic print ticket is evaluated, based on the printing and finishing instructions selected for the target device. The generic print ticket is removed from the printable document and a corrected print ticket is produced based on the printing and finishing instructions selected for the target device. The corrected print ticket is injected into the printable document and transmitted from the portable computing device to the target device.

Methods and systems receive an electronic scanned image generated by activity of an application running on a portable computerized device, and calculate a cryptographic digest from data of the electronic scanned image using a second computerized device. Also, such methods and systems encrypt the cryptographic digest using an encryption key stored on the portable computerized device to create a content signature of the cryptographic digest, and send the content signature to the second computerized device. The authenticity of a copy of the electronic scanned image provided by the second computerized device is verified by recalculating the content signature (based on the copy of the electronic scanned image) using the encryption key from the portable device.

Scan image authentication

Systems, methods, and computer-readable media for managing extensibility, e.g., on a network of multi-function devices are provided. The system includes an application catalog, in communication with an application database of a catalog server and configured to load applications therefrom. The system also includes a device manager configured to discover one or more devices on a network and to allow selection of one or more selected devices from among the one or more devices. The system further includes a data transfer system in communication with the one or more devices and to cause an application to be transmitted from the application catalog to the one or more selected devices, such that the one or more selected devices receive the application without communicating directly with the application database.

A method of printing a document from a mobile device coupling the mobile device to a print device. The method may also include launching a tap-to-print application software on the mobile device in response to the coupling, identifying a document to be printed via the tap-to-print application, and transmitting the document to be printed to the print device by the tap-to-print application. The tap-to-print application does not modify an operating system of the mobile device.

System and method for achieving tap-to-print functionality on a mobile device

In implementations, a computer-implemented method for operating a multifunctional device (MFD) is disclosed. The computer-implemented method can include receiving a identification information from a tag that is associated with a MFD; identifying, by a processor, one or more operations based on the identification information that was received; and transmitting the one or more operations to the MFD.

System and method for keyed operation of devices using near field communication

A method for troubleshooting a problem with a device includes acquiring device data for the device, receiving a user's query concerning a device in a natural language, presenting possible refinements to at least a portion of the user's query for defining a problem statement, presenting candidate solutions that are associated with the defined problem statement in a knowledge base, at least one of the presentation of possible refinements and the presentation of candidate solutions being informed by device data that is linked through a diagnostic model of the device to at least one of the problem statements and candidate solutions.
