Systems for collaboration system application authentication. A collaboration system identifies a downloadable application that comprises at least one operation that functions only after obtaining user authentication credentials. The application is configured to invoke one of a plurality of different authentication procedures based on a set of server-provided authentication style parameters. After establishing a connection between an application server that interfaces with the user device that runs the application, the collaboration system determines the set of authentication style parameters, wherein the determination is based at least in part on an identification of the user device or based at least in part on an identification of a user of the user device. The application server sends at least a portion of the set of authentication style parameters to the user device. The application obtains user authentication credentials by invoking one or more authentication procedures based on received server-provided authentication style parameters.

Server-side authentication policy determination for mobile applications

Image processing to reduce or eliminate jitter when visually highlighting a target capture area of an image capture device such as a smart phone or camera. A method embodiment commences upon receiving a sequence of one or more video frames taken by the image capture device. A routine to identify the largest polygons in the video frames is applied to the sequence. Uncertainty in identification of the largest polygons is reduced or eliminated by applying intra-frame filters to the polygons. Visible jitter that can arise from inter-frame uncertainty when selecting and highlighting target capture areas can be reduced or eliminated by applying inter-frame filters so as to retain selection of a particular target capture area even in the presence of certain capture device movements. A jitter-free representation of the target capture area is visually displayed on a display screen of the image capture device.
