DETAILED DESCRIPTION
DETAILED DESCRIPTION
[0016] The following description is of a preferred embodiment.
[0017] The present invention will be further illustrated in the following examples.
[0018] Figure 1 shows in a network diagram an example of a system overview 100 of a design, development and operational environment for deploying feature rich applications (that use web services) to mobile devices and desktop personal computers, in accordance with an embodiment of the invention. The system overview 100 comprises one or more or mobile client components (or handheld terminals) for allowing a user to collect, review and modify data; a server component 104 for providing applications and connectivity options to external systems; a network 106 for allowing the handheld terminals 102 to communicate with the server component via a communications protocol; and a back-end system (or host) 108 for providing a database or enterprise resource planning (ERP) system. Examples of mobile components include personal computers (PCs), vehicle mount computers, tablet PCs, and devices with embedded operating systems, etc.
[0019] Figure 2 shows in a layer diagram another example of a system overview of a design, development and operational environment, in accordance with an embodiment of the invention. The mobile client component 102 comprises one or more client applications 202 that communicate with a web services client 204.
The server component 104 comprises an Internet information server (ITS) 206 for communicating with the web services client 204, one or more server applications 208 and a host interconnect module 210 for communicating with the host (or back-end system) 108. The server applications 208 communicate with both the ITS 206 and the host interconnect module 210.
The server component 104 comprises an Internet information server (ITS) 206 for communicating with the web services client 204, one or more server applications 208 and a host interconnect module 210 for communicating with the host (or back-end system) 108. The server applications 208 communicate with both the ITS 206 and the host interconnect module 210.
[0020] An application console may be installed as client application 202 on the mobile client component 102 to provide a presentation layer and application framework that end users use to collect, review and modify data. The application console communicates with the server component 104 via web services running on the ITS 206. The server component 104 is a middle tier where data is synchronized before being sent to the back-end system 108.
[0021] The server component 104 provides the applications and connectivity options to integrate back-end systems 108.

[0025] Figure 4 shows in a flowchart an example of a method of managing user credentials (400), in accordance with an embodiment of the user credential management system 300. The method (400) comprises the steps of authenticating a user login to a mobile device (402), determining a user credential associated with the user login (404), and associating user credentials to a communication message between the mobile device and a server (406). Preferably, the user credential may be determined by mapping an authentic user login to a user credential.
Alternatively, the user login may generate the appropriate user credential. A message may be associated with a user credential by automatically attaching the user credential to the message during communication. Other steps may be added to the method (400), such as sending user credentials to a mobile device, receiving credentials from a server, and creating and storing user credentials.

[0026] Figure 5 shows another example of a user credential management system 500.
The user credential management system 500 comprises the authentication module 302, the user credential locator module 304, the message transforming module 306, a credential receiver module 508 for receiving credentials from a server, and a mobile credential repository 510 for storing one or a group of user credentials on the mobile device. These components 302, 304, 306, 508, and 510 are preferably implemented as code in a mobile device. The user credential management system 500 further comprises components implemented as code on a server, including a credential sender module 512 for sending user credentials to a mobile device, and a user credential repository 514 for storing a plurality of user credentials. Other components may be added to the user credential management system 500, including an application provisioning system for administering and delivering software applications or components to client devices 102.

Other components may be added to the user credential management system 500, including an application provisioning system for administering and delivering software applications or components to client devices 102.
[0027] A user database (or the user credential repository 514) is centrally managed on the server. Preferably, this database is encrypted and assigned to the workstations using application provisioning and downloaded to the workstation as any other component assigned to it. Alternatively, the workstations can download the database file from the server in other means, such file transfer protocol (ftp), web services, etc.
Once the database is present on the workstation, the client runtime environment, or application console, prompts the user to login. After successful login, the user's identity is attached to every single web service request the application makes using web services enhancements (WSE).
Once the database is present on the workstation, the client runtime environment, or application console, prompts the user to login. After successful login, the user's identity is attached to every single web service request the application makes using web services enhancements (WSE).
[0028] Each user can have one or many extended credentials attached to them on the server that are not downloaded to the workstation. When the client application calls the web service that is supposed to send the data to ERP (e.g., SAP) for which further credentials are required, the service can search the credentials of the calling user and use them to login to ERP system.
[0029] Figure 6 shows in a flowchart another example of a method of managing user credentials (600), in accordance with an embodiment of the user credential management system 500. The method (600) comprises the step of storing user credentials in a repository on a server (602). The user credentials (for example, a user name and password) may be stored in one database table. Credentials to foreign systems (e.g., ERP) may be stored in another database table. A user credential or group of user credentials may be sent to a mobile device (604). The mobile device receives the user credential or group (606) and stores same in a local mobile credential repository (608). When an application is started (610), a user login is authenticated (402). A user credential associated with the user login is located (404). A
communication sent by the user between the mobile device and the server is associated with the user credential (406) as found in the mobile credential database and server user credential database. Preferably, when the message from the client arrives, the credential attached to it is re-authenticated on the server again, to make sure that someone along the way did not inject a bogus credential. Thus, the username and hashed password attached to the message is again authenticated on the server, as a precaution. Other steps may be added to the method (600), including storing a plurality of user credentials for a single user, the plurality of user credentials associated with a plurality of foreign servers, and associating messages between the mobile device and foreign servers with the appropriate user credential.

[0030] Typically, operating systems for mobile devices do not offer an authentication mechanism in a disconnected environment. Users of the user credential management system 300, 500 and method 400, 600 can authenticate the user on a workstation even if the user is not contacting the server. The single sign on brings transparency to the user when the user's data is further posted to ERP system. The user does not need to know or be aware of the user credentials to the ERP system.
[0031] Advantageously, the system 300, 500 and method 400, 600 of user credential management allows for centrally managed user and credential management. The login to multiple backend systems is transparent to the user (only needs one user name and password--single sign on).
[0032] The user credential management system and method according to the present invention may be implemented by any hardware, software or a combination of hardware and software having the above described functions. The software code, either in its entirety or a part thereof, may be stored in a computer readable memory.
Further, a computer data signal representing the software code which may be embedded in a carrier wave may be transmitted via a communication network.
Such a computer readable memory and a computer data signal are also within the scope of the present invention, as well as the hardware, software and the combination thereof.
