Sending out sensitive data on unsecured networks carries a considerable amount of risk. Anyone with malicious intentions and the proper knowledge can easily hack into your network and intercept the messages. If confidential documents containing financial information, passwords, or other important data get into the wrong hands, there can be a major security problem. In order to keep yourself safe, you can encrypt your data with a key and send the key to the intended recipient. However, some advanced hackers can even break some high level encryption if they locate the file. Another method to send your data in a safe way is by using a Steganography technique that involves infusing your data inside an image without changing the image itself. Steg is one such tool that performs the job flawlessly. This way, even if your file is intercepted by anyone, it will be a normal image file in the eyes of others, and there will be no visual indication of the encoded data. Keep reading to find out how to embed your sensitive data into an image using Steg.
