METHOD FOR REAL-TIME PREVENTING LEAK DATA

摘要

Provided is a method for preventing data leakage in real time, comprising a step for monitoring all files which are stored and edited in a user terminal in real time; a step for adding a file header comprising an initial vector for all files of the user terminal and encoding the initial vector which adds an offset by using a CTR mode; a step for monitoring all files read by a call through a user interface in the user terminal in real time; and a step for decoding the read file by using the file header, the offset, and the CTR mode.
