摘要： Methods, systems, and computer programs for verifying a password are disclosed. For example, the password can be verified on a mobile device to control user access to the mobile device. In some implementations, a mobile device includes a user interface, a main processor, and a co-processor. The user interface receives a submitted password value from a user. The main processor calls the co-processor to provide a hash chain input value based on the submitted password value. The main processor evaluates a hash chain based on the hash chain input value provided by the co-processor. Evaluating the hash chain generates a submitted password verification value. The submitted password verification value is compared to a stored password verification value stored on the mobile device. Access to mobile device functionality may be permitted or denied based on a result of the comparison.

摘要： Methods and devices for encoding a point cloud. More than one frame of reference is identified and a transform defines the relative motion of a second frame of reference to a first frame of reference. The space is segmented into regions and each region is associated with one of the frames of reference. Local motion vectors within a region are expressed relative to the frame of reference associated with that region. Occupancy of the bitstream is entropy encoded based on predictions determined using the location motion vectors and the transform associated with the attached frame of reference.
