摘要： 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.

摘要： 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.

摘要： A computer-implemented method and system of quarantining user location information receives from a user device user location information that includes personally identifiable user data and user position data associated with one or more geographic positions of the user. The user location information is temporarily stored in a quarantine data storage database for a predetermined quarantine time, during such time it can be used for various analyses. After the quarantine time, personally identifiable user data of the user location information is filtered out before the user position data is sent for long-term storage to a filtered data storage system.

摘要： An alert server is operative to notify users when they are in proximity within one another. The alert server may determine to alert a first user of the proximity of a second user when the second user is in an unusual location. The alert server may determine that the second user is in an unusual location when the second user is outside his or her routine geographic location. The alert server may determine whether the second user is outside his or her routine geographic location by assigning confidence values to geographic locations that the second user has previously visited. The alert sent to the first user may be in the form of a text message, e-mail, or other electronic communication. The first user may receive the alert on a mobile device, such as a cellphone, smartphone, netbook, or other mobile device.

摘要： A method, system, and apparatus for minimizing run-time exception handling overhead from invoked function calls. The present invention novelly minimizes execution of exception checking code and exception handling code in a caller when the callee is a compiled method. In the present embodiment the callee novelly treats the caller as a compiled method thereby enabling the callee to return to the exception handling label of the caller if an exception needs to be handled and to return and continue normal code execution if an exception does not need to be handled. Thereby the present invention minimizes execution of exception handling code in the caller. Further, the present embodiment novelly creates code with the layout of a compiled method when a caller is not a compiled method so that a compiled callee may treat its caller as a compiled method.
