摘要
The present invention relates to a method and a system for protecting data in a computer network. A device is placed on a network edge in such a way, that all outgoing data has to pass through it. Separately, a set of data that is not allowed to leave the network is defined and stored in a secure form (typically, one way hash). The device determines the network protocol, file type, transforms and normalizes the passing data, and seeks the presence of the data from the defined set. If a threshold amount of the protected data is present, the device takes one of the following actions: block, alert, log, redact, store, redirect, encrypt, notify sender.
