Abstract: An integrated circuit includes a data propagation path including a flip-flop. The flip-flop includes a first latch and a second latch. The integrated circuit includes a third latch that acts as a dummy latch. The input of the third latch is coupled to the output of the first latch. The integrated circuit includes a fault detector coupled to the output of the flip-flop and the output of the third latch. The third latch includes a signal propagation delay selected so that the third latch will fail to capture data in a given clock cycle before the second latch of the flip-flop fails to capture the data in the given clock cycle. The fault detector that detects when the third latch is failed to capture the data.

Abstract: A computer-implemented method includes retrieving, by one or more processing devices and from one or more data repositories, user information; generating, based on the retrieved user information, a digital personal profile that is a composite of a set of pre-defined attributes; determining an aggregate strength of values of the set of pre-defined attributes in the digital personal profile; and generating, based on the determined aggregate strength, a digital security score that measures a level of online security of accessing resources over a computer network.

Abstract: Testing the components of I/O paths in an integrated circuit at-speed operation (i.e., the speed at which the integrated circuit would be operated during normal non-test mode). In an embodiment, boundary scan cells of different paths are connected in a scan chain, and each scan cell tests the corresponding component (e.g., buffer) by launching data at a first time instance and receiving the result of the data at a second time instance, with the duration between the first time instance and the second time instance corresponding to the at-speed operation. If the data is received accurately, the component may be deemed to be operating accurately at-speed.
