摘要： Several approaches have been proposed to anonymize relational databases using the criterion of k-anonymity, to avoid the disclosure of sensitive information by re-identification attacks. A relational database is said to meet the criterion of k-anonymity if each record is identical to at least (k ? 1) other records in terms of quasi-identifier attribute values. To anonymize a transactional database and satisfy the constraint of k-anonymity, each item must successively be considered as a quasi-identifier attribute. But this process greatly increases dimensionality, and thus also the computational complexity of anonymization, and information loss. In this paper, a novel efficient anonymization system called PTA is proposed to not only anonymize transactional data with a small information loss but also to reduce the computational complexity of the anonymization process. The PTA system consists of three modules, which are the Pre-processing module, the TSP module, and the Anonymity model, to anonymize transactional data and guarantees that at least k-anonymity is achieved: a pre-processing module, a traveling salesman problem module, and an anonymization module. Extensive experiments have been carried to compare the efficiency of the designed approach with the state-of-the-art anonymization algorithms in terms of scalability, runtime, and information loss. Results indicate that the proposed PTA system outperforms the compared algorithms in all respects.

An Ultra-Compact Low Power Self-Capacitive Touch Screen Readout IC Embedding Reconfigurable Noise Immunity and Current-Driven Capacitance Compensation
摘要： This brief presents the design of a readout IC for dot-matrix, self-capacitive touch screen system. To accommodate only a capacitive change with large base capacitance of electrodes, it employs an encoded multiple sensing method as well as current-driven offset compensator, that strike circuit complexity, power consumption and handling range of the base capacitance. The current-driven offset compensator can provide compensation current up to 300 μA with a 4-bit tunable magnitude and mismatch calibration between source and sink currents. It can also perform adaptive noise rejection for in-band as well as out-band interferences by introducing hybrid touch screen panel (TSP) drive scheme. The measurement results show that it achieves 47.2 dB signal-to-noise ratio (SNR) and 31 dB in-band noise rejection with 220 kHz TSP drive frequency and 330 Hz scan rate when a 4 mm metal pillar is used. The proposed front end circuit, fabricated on a 130-nm CMOS technology, occupies an area of 0.128 mm2 and consumes 1.04 mW of power for 16 channels 1.3-in, dot-matrix On-cell TSP for rigid OLED.
