ABSTRACT
Steganography is a method to hide the secret messages in a way that only sender and receiver know the existence of hidden message inside the sent image. However, the use of only pure steganography to protect message during transmission expose that data to the attacker by using various steganalysis tools have been made for detecting the hidden message in steganography image make it no longer secured. The main purpose of this project is using a cryptography technique cooperate with the steganography to promise more security and invisibility in hiding a secret message inside an image. Hence, the RSA algorithm will be used as a technique to encrypt the hidden message with a method of Enhanced Least Significant Bit (LSB) algorithm to hide the encrypted message. The expected results of this project is provides security for data hiding and its invisibility in an stego-image.
INTRODUCTION
- Steganography is one of the powerful technique to hides the existence of the secret message inside a cover object.
- Cryptography is an effective way to secure sensitive message and makes it immune to attack.
- A tool is designed by using the combination of steganography and cryptography to increase the security of the secret message.
- In conclusion, the weaknesses in steganography technique will be covered by the advantages in cryptography technique.
OBJECTIVE
- To design a steganography tool to hide secret message invisibly in an image.
- To implement RSA algorithm for data encryption and enhanced LSB technique in hiding the secret data into the cover object.
- To test the tool functionality in hiding and securing secret message.
RESULT
CONCLUSION
•A secured LSB technique for image steganography is proposed and implemented to decrease the variation of image bits.
•The technique of cryptography, RSA Algorithm is used to secure the secret data so that is not easy to break the encryption without the key.
•The secure data in image steganography based on RSA algorithm is enhanced and safe to send the secret data over any unsecure channel or internet.
