A secured protocol is defined for permanent authentication through continuous user verification. The protocol determines respective timeouts based on the quality, frequency and type of biometric data transparently acquired from the user. But the existing system does not own an identity of the user interacted with the system. The main mechanism of proposed framework includes object tracking for user interrupted motions, and colour profile variation, edge detection based variation and the usage of immediate motions. For the initialization of colour based tracking, extend a Bitmap Algorithm for robotically initializing contours at the first frame. For user interaction-based contour evolution, the anonymous shape in sequence and the local basis information are joined to compare the colour, for the handling of unexpected motions; pixel block is accepted to capture the global activity which is functional to the outline in the current frame to make an initial contour in the next frame.
