Method and system for controlling transmission of information

摘要

A method ( 300 ) and system for preventing private information to be collected and sent to the INTERNET without the consent of a user of a client computer. Every time the user wishes ( 317 ) to run a new application program, an isolator engine is invoked ( 303 ). The isolator engine intercepts ( 329 ) all the output operations ( 327 ) of the application program attempting to send messages to the INTERNET. Each message is compared ( 330 - 345 ) with a privacy list storing a series of strings (such the name of the user, his or her private e-mail address); if a match occurs, the user is asked ( 352 ) whether he or she desires to continue or abort execution of the application program.
