Abstract

A computer automated system and method comprising configuring a single or plurality of mobile devices over a network, validating the configured devices, and communicating contextual information to the configured devices. The devices are authenticated and the authentication is sent to a server over the network, when a contextual service, controlled/offered by the server through a contextual service point in communication with the server, is invoked by the configured mobile device in the vicinity of the contextual service point. The mobile device is then enabled to consume a contextual service, offered by and delivered at the contextual service point, either from within the mobile device or over the network.

BACKGROUND

Field

In general, the problem is to be able to detect the presence of and authenticate a user in a context, so that some services can be delivered to the user in that context. In the context of secure printing, this translates to releasing print jobs queued by the user when he is near a secure printer. In the context of boarding a plane, this translates to allowing a checked-in passenger through the boarding gate.

Related Art

Earlier, the problem would be solved in the work environment by placing a badge reader (active element) in the context, and the employee authenticating by showing his or her issued badge (passive element). Likewise, in the public space, an encoded token (say a boarding pass with a magnetic strip) would be issued to the user and scanned by a reader at the boarding gate in conjunction with other identity establishing mechanisms.
The issue with these mechanisms were: 1. The reader hardware had to be placed in the context (one per printer or one per boarding gate, for example), and the passive element would be with the user. This would add to the infrastructure cost. 2. The reader hardware had the intelligence to read the user tag, authenticate the user/tag, and release the service.
However, with the proliferation of mobile wireless devices, and especially smart mobile devices, there is an opportunity to swap the active and passive elements, thereby reducing infrastructure cost and consolidating processing and service release at the server.
There now are available, several near field communication protocols, which are supported by the major mobile operating systems. The mobile operating system, in general, monitors the communication channel, and then invokes the relevant app that can handle the communication.
NFC is one such widely supported near field technology. The NFC tag is generally passive, and contains the following: a tag ID that can be used to uniquely identify the tag; an authentication token that can be used to authenticate the tag itself; an app identifier in a format understood and used by the mobile operating system to invoke the relevant app; and additional context information that can be read by the app itself.
Once the mobile device is in proximity of the NFC tag, the mobile operating system invokes the relevant app and passes all the other parameters above, to it for further processing. From a usability perspective, the OS even prompts the user to download and install the relevant app to the user device, if not already present. The app presents the graphical user interface which allows the user to provide his credentials. The app now has three raw pieces of information—the user credentials, the tag info, and the additional context info, in addition to having established presence of the user in the context due to the nature of the technology. The app sends all of the info to the server, which authenticates the user and the tag. Once authenticated, it can use the additional context info to deliver the service in the context.

Embodiments disclosed eliminate the need for reader hardware to be coupled to the contextual service point (for example, at each networked printer or at each boarding gate). This is because the user's device now comprises the active element of the short range communications capability, thus drastically reducing the infrastructure cost, thereby consolidating processing and service release at the server.
Example embodiments show how several near field communication protocols, can be combined with mobile operating systems and leveraged to invoke a relevant contextual service at a contextual service point or area, based on a monitored short range communication. Additionally, the major mobile operating systems are leveraged to monitor the communication channel and via passive NFC tags determine a tag ID to identify the tag, an authentication token that can be used to authenticate the tag, an application identifier in a format understood and used by the mobile operating system to invoke a relevant application, and any other additional context information that can be read by the application.
Once the mobile device is in proximity of the NFC tag, the mobile operating system invokes the relevant app and passes all the other parameters above to it for further processing. From a usability perspective, the OS even prompts the user to download and install the relevant app to the user device, if not already present. The app presents the graphical user interface which allows the user to provide his credentials. The app now has three raw pieces of information—the user credentials, the tag information, and the additional context information, in addition to having established presence of the user in the context due to the nature of the technology. The app sends all of the information to the server, which authenticates the user and the tag. Once authenticated, it can use the additional context information to deliver the service in the context.
Embodiments disclosed enable pull print solutions, allowing users to queue print jobs to a server for secure printing using a mobile app after authenticating the user. Embodiments enable location agnostic contextual service points (printers, boarding gates, etc.) wherein the server combines information of user identity at a printer with passive SRCC (NFC) tag associated with the printer, identifying both the user and the printer. Embodiments enable queuing of jobs to the server via the user mobile device, and secure release by the server of the queued job at the contextual service point (printer, boarding gate, etc.)
