    • Systems and methods according to aspects of the invention verify requests for information over a network. Computing devices communicating over a network transmit numerous signals with various types of information including spatial information, temporal information, device-specific information, and transmission specific information. This information may be used to generate statistical records of valid request for information. Various combinations of these signals may be used to determine whether a request for information is a valid request based on the statistical records associated with the signals. Where a request for information has been verified, the system and method may provide the information. Where the request for information has not been verified, the system and method may deny the request for information. Thus the system and method may be used to prevent and block scraping and spamming attacks.
    • 根据本发明的方面的系统和方法通过网络验证对信息的请求。 通过网络进行通信的计算设备通过包括空间信息,时间信息,设备特定信息和传输特定信息的各种类型的信息来发送大量信号。 该信息可用于生成有效信息请求的统计记录。 可以使用这些信号的各种组合来基于与信号相关联的统计记录来确定信息请求是否是有效请求。 如果信息请求已经被验证,则系统和方法可以提供信息。 在信息请求尚未得到验证的情况下,系统和方法可能会拒绝信息请求。 因此,系统和方法可用于防止和阻止刮除和垃圾邮件攻击。

    • An electrostatic discharge protection device for protecting an inner circuit, which is operated in a source voltage, is provided and includes a protection unit and a control unit. The protection unit provides a discharge path for transmitting an electrostatic signal from a pad to a ground line. According to a voltage level at a control end, the protection unit adjusts a holding voltage and a triggering voltage determining whether to conduct the discharge path. When the source voltage is supplied, the control unit transmits the input voltage to the control end of the protection unit, so as to raise the holding and the triggering voltages of the discharge path. When the source voltage is not supplied, the control unit switches the control end of the protection unit to a floating condition by the electrostatic signal, so as to lower the holding and the triggering voltages of the discharge path.
    • 提供一种用于保护以电源电压工作的内部电路的静电放电保护装置,并且包括保护单元和控制单元。 保护单元提供用于将静电信号从焊盘传输到接地线的放电路径。 根据控制端的电压电平,保护单元调整保持电压和触发电压,确定是否进行放电路径。 当提供源电压时,控制单元将输入电压发送到保护单元的控制端,以提高放电路径的保持和触发电压。 当不提供源极电压时,控制单元通过静电信号将保护单元的控制端切换到浮动状态,从而降低放电路径的保持和触发电压。

    • A computer-implemented method and system of building a user reputation database for use in a user location data system. The method and system receive user location information containing personally identifiable data of a user and user position data. The user position data may or may not represent one or more actual geographic positions of the user. The user location information is temporarily stored and analyzed to provide a spam score associated with the user position data indicative of whether the user position data represents the actual geographic positions of the user. Data indicative of the spam score is also provided to user reputation database to store a user reputation score associated with the user.
