Abstract
A method and apparatus for preventing leakage of sensitive information from a computer is described. The method includes identifying data entered into the computer system as sensitive data, tainting the sensitive data with at least one taint bit to form a tainted data, tracking the tainted data within the computer system and identifying at least one condition that compromises the security of the tainted data. The system is a computer system including taint analysis software for identifying data entered into the computer system as sensitive data, tainting the sensitive data with at least one taint bit to form a tainted data, tracking the tainted data within the computer system and identifying at least one condition that compromises the security of the tainted data.
