    Abstract: The disclosed systems and methods are directed to detecting sensitive data on a computing device. This includes matching predetermined keywords in input data, to determine data in vicinities of matched keywords in the input data in which sensitive data is likely to be found, and matching predefined patterns associated with sensitive data to the data in vicinities of matched keywords to detect sensitive data. Matching the predetermined keywords occurs prior to matching the predefined patterns, and the data in vicinities of matched keywords is substantially shorter than the input data.

    Abstract: The present disclosure relates to telecommunication, and in particular, to a base station Radio Frequency (RF) duplexer, an RF module, and an RF system. A base station RF apparatus provided herein includes: an enclosure, an intermediate RF processing unit, and a duplexer. The enclosure is located on the duplexer; the intermediate RF processing unit is located inside a cavity enclosed by the enclosure and the duplexer, or on the duplexer; a duplexer cavity and a heat dissipation part exist on the surface of the duplexer; the opening of the duplexer cavity is opposite to or against the enclosure; the heat dissipation part is designed to dissipate heat of the intermediate RF processing unit; and the duplexer is integrally molded. The foregoing technical solution requires no external fasteners, reduces the time of production and assembly. In addition, waterproof design and shielding design are not required, and thus improves the reliability.
