Image Steganography Using LSB in MATLAB | Image Processing
The word Steganography is the combination of two Greek words first is Stegano, which means hiding and other is Graphy that means technique.
Abstract:
Thisย technique by which messages can be hidden within digital images using MATLAB programming language. Steganography is exactly maintaining the confidentiality and privacy of critical information and protecting them from potential sabotage, theft or unauthorized access.
Despite the large number of steganography carriers and methods provided by digital technology, images, audio, and video are still the most common and the most appropriate digital carriers, and there is the largest number of steganography techniques developed for them.
Objectives:
- To perform steganography of time and date for keeping git in secrete pattern.
- To use LSB based steganography for hiding time and date.
- To preventing steganography from steganalysis tools, and making the steganography to vary on the basis of frame number.
- To develop and use algorithm for keeping the video tamper proof utilizing secrete time and date stored from the location depending upon the position of frame in video.
Steps to Encode data:
Step:1 Browse the image in which you can embed the data.
Step: 2 Enter the text message who want to hide.
Step: 3 Enter the layer in which you want to embed the data.
Step: 4 Enter the password.
Step: 5 Enter the password layer.
Step: 6 Enter the layer in which you want to set the length of message.
Step: 7 Embed the all data into image file and create new image file.
Steps to Decode data:
In decoding part, we have all information regarding the message like starting point of message, length of message, password, message layer etc.
