Abstract: A method for carrying out a wireless transaction for authorization through a transaction processing system between a first computing device and a second computing device is described. The first computing device establishes a secure network connection with a third computing device. The first computing device initiates the wireless transaction with the second computing device. The first computing device provides information to perform a security protocol for the transaction to the third computing device over the secure connection. The performance of the security protocol includes determination of a secure result. The first computing device receives a dummy secure result from the third computing device, and performs the wireless transaction with the second computing device using the dummy secure result. The third computing device prepares a true secure result for the wireless transaction. The dummy secure result may be used to reconcile the wireless transaction with the true secure result.

Abstract: The invention provides techniques for detecting and responding to potentially unintended checkout operation made by consumers using legitimate payment credentials to initiate the transaction. The invention operates prior to a transaction being approved, rather than after the event, enabling the invention to provide an efficient method of preventing unintended checkout proceeding to actual purchase. Broadly speaking the invention analyses a transaction request in real-time or near real-time and predicts how likely it is that the transaction is unintentional. In cases where it is deemed likely that the transaction is unintentional, the consumer that initiated the transaction is required to confirm that they wish for the transaction to go ahead in order to complete the transaction. The user's confirmation is stored and is available at a later date should the consumer attempt to dispute the transaction. This greatly reduces the likelihood of unintentional transactions being processed.

Abstract: Systems, methods, and computer-readable media for offloading session management processing into a forwarding plane. In some examples, a subscriber is coupled to a network endpoint through a session manager during a network session of the subscriber in a network environment. A session manager offloading system of the session manager can be maintained in a vector packet processing system in a forwarding plane of the network environment. The session manager offloading system can be configured to offload processing from the session manager into the forwarding plane. Further, at least a portion of subscriber traffic in a stream between the subscriber and the network endpoint through the session manager can be intercepted. Subsequently, the at least the portion of the subscribed traffic that is intercepted can be processed at the session manager offloading system as part of offloading the processing from the session manager into the forwarding plane.

Abstract: A method of providing a secure service at a computing node is described. The secure service is for a requesting party external to the computing node. The following steps take place at the computing node. A service request is received from the requesting party. This service request comprises a request to generate a credential. The credential is then generated, and service-related information is obtained. The credential and the service-related information are encrypted using an encryption process to form an encrypted message part. A service-identifying clear message part is also created, and a message is sent comprising the clear message part and the encrypted message part to the requesting party. Methods of using such a message to validate the credential, and of using such a message to confirm the integrity of service-related information held in the message, are also described, as is computing apparatus adapted to carry out one or more of these methods.

Abstract: A computing system may determine a head pose and a wrist pose of a user based on sensor data captured by a head-mounted device. The computing system may further receive an image captured by a camera of the head-mounted device that includes at least portion of the body of the user. Using this image, the computing system may determine one or more regions in the image that correspond to the body of the user, and determine, based on these regions and a camera pose of the camera, a three-dimensional volume constraint in which an elbow of the user is likely to be located when the image was captured. From this information, the computing system may utilize the head pose, the wrist pose, and the three-dimensional volume constraint to infer a body pose of the user that includes at least an inferred elbow pose associated with the user.
