Abstract: A mobile computer system hosts mobile application and a collaboration module. The collaboration module is adapted to enable the mobile application to communicate with a further mobile application, hosted on a further mobile computer system, and to access functionality of an enterprise application, hosted on an enterprise system.

Abstract: A system for providing secured access to an application service includes a challenge provider that uses a first cryptographic technique to provide a challenge to a client seeking access to an application service. The client uses a second cryptographic technique to generate a response, and provides the response to an authentication service. The authentication service grants the client access to the application service only if the challenge and response are authenticated using a first authentication technique complementary to the first cryptographic technique and a second authentication technique complementary to the second cryptographic technique, respectively.

Abstract: Methods and computer systems are provided for workflow management. A workflow engine may be provided that creates workflow items. Each workflow item may include a self descriptive part that specifies details for generating a device independent representations of a corresponding workflow item. Further, a workflow manager may be provided that generates the device independent representation based on the self descriptive part.

Abstract: A system for providing secured access to an application service includes a security token that couples to the application service. The security token performs a first element of a cryptographic technique, such as, for example, encryption or decryption. A proximity token is provided that is associated with the security token. The proximity token performs a second element of the cryptographic technique to validate a communication between the application service and the security token. The proximity token is operable to validate the communication only when the proximity token is located within a predetermined validation distance from the security token or the application service. The security token may perform the first element of the cryptographic technique to verify that the proximity token has validated the communication between the application service and the security token.
