Practical Applications
Journalists & Activists
For professionals working in sensitive environments, Steghide provides a method to securely transmit information without raising suspicion. Photos shared online can carry encrypted messages, protecting both the sender and receiver from surveillance.
This technique has been particularly valuable in regions where free speech is restricted, allowing vital information to reach the outside world.
Corporate Security
Businesses can use Steghide to protect intellectual property and sensitive communications from corporate espionage. Confidential data can be embedded in ordinary-looking files shared through regular channels.
This adds an extra layer of protection beyond traditional encryption, as the very existence of the data remains hidden.
