Abstract: A structural design-for-test for diagnosing broken scan chain defects of long non-scannable register chains (GPTR) The GPTR and the system for testing and diagnosing the broken LSSD scan-only chains rapidly localize defects to the failing Shift Register Latch (SRL) pair. The GPTR modifies the latches used in the GPTR scan chain to standard LSSD L1/L2 master-slave SRL type latch pairs; connects all the system ports of the L1 latches to the Shift Register Input (SRI) and clocked by the system C1-clk while the L1 scan port is clocked by the A-clk and L2 scan port is clocked only by the B-clk. The L1 latches are connected to at least one multiplexer having a first output connected to an input of each odd SRL, and a second output connected to an input port of each even SRL.

Abstract: A system and method of determining likelihood of counterfeiting without inspection of currency compares signals returned by uniquely customized RFID chips when interrogated, preferably incident to a transaction. The RFID information is compared to RFID information for bills known to be in circulation in order to validate a given currency bill. Usage patterns can be determined from statistical analysis of such reports and reported usage patterns will statistically differ significantly if not radically with the number of RFID chips returning the same RFID information and such differences will increase in either or both of geographic locations of reports and frequency of reports with increase of the number of bills having duplicated RFID chips. The basic infrastructure for practice of the invention is also capable of tracking genuine currency following, for example, a theft or other criminal activity.

Abstract: Methods for testing a semiconductor circuit (10) including testing the circuit and modifying a well bias (14, 18) of the circuit during testing. The methods improve the resolution of voltage-based and IDDQ testing and diagnosis by modifying well bias during testing. In addition, the methods provide more efficient stresses during stress testing. The methods apply to ICs where the semiconductor well (wells and/or substrates) are wired separately from the chip VDD and GND, allowing for external control (40) of the well potentials during test. In general, the methods rely on using the well bias to change transistor threshold voltages.

Abstract: Monitoring text input from a keyboard and from a pointing device, is done by monitoring input from a user keyboard for entry of text and cursor controls; monitoring input from a pointing device; logging keyboard entered text to a key log; and responsive to input selectively from the pointing device and keyboard selectively signaling a command action, determining text contents of the command action and logging the text contents to the key log in sequence with the keyboard entered text. A temporary storage is provided for storing copied content, and for storing pointing device input device definitions and key command definitions for each application. A log file stores a key log table for each application; and a key logger stores to the key log table entered text reconstructed with reference to the pointing device position, the copied content, the pointing device input device definitions, and the key command definitions.

Abstract: This embodiment replaces the use of LBIST to get a pass or no-pass result. A selective signature feature is used to collect the top failing paths, by shmooing the chip over a cycle time. These paths can be stored on-chip or off-chip, for later use. Once the chip is running in the field for a certain time, the same procedure is performed to collect the top failing paths, and this is compared with the stored old paths. If the order of the top paths changes, it indicates that (for example) there is a path (not the slowest path before) that slows more than others, which could be potential reliability concern. Therefore, a potential reliability failure is identified in the field.

Abstract: A method for preventing password theft through unauthorized keylogging includes detecting, from a host application, a request for a password input by a user of an input keyboard device; activating a randomly generated keyboard map uniquely associated with the host application such that a first set of keystroke values inputted by the user results in a second, converted set of keystroke values transmitted to the host application, in accordance with the randomly generated keyboard map uniquely associated therewith; and upon completion of a password entry process by the user, deactivating the randomly generated keyboard map such that subsequent keystroke values inputted by the user are no longer converted to the values according to the keyboard map.

Abstract: Methods, systems and program products for securely voting by providing a secure voting module in communication with a voting device. A voter signs onto the voting device using a unique voter identification, and the voter's voting selections are written to the voting device. A scrambled voter identification is generated using the unique voter identification and a unique encryption value of the secure voting module, whereby the voting selections and the scrambled voter identification are stored in the secure voting module. Once voting has ended, first and second fuses are blown within the secure voting module for destroying the unique encryption value and for permanently storing the voting selections and scrambled voter identification in a read only secure voting module that maintains voter anonymity while preventing any further physically writing thereto. The voting results may then be counted, re-counted or validated.
