Existing system

In android there are very few applications regarding the steganography but they are not providing any security to the user any user can encrypt the data at the same time he can decrypt.

Proposed system

In the proposed system we are providing security to the user by using different algorithms like LSB2Bit and Cipher key text

Modules:

Encrypting Text:
By using the cipher key algorithm we encrypt the users text based on the key provided by the user.

Encrypting Image:
By the using the LSB2Bit algorithm we encrypt the encrypted text in the image.

Decrypting Image:
By the using the LSB2Bit algorithm we decrypt the encrypted text from the image.

Decrypting Text:
Once we get the text from the module 3 we decrypt the text by using the cipher key algorithm and the user’s key.

Conclusion:

Steganography is the art of hiding data in the images/text/videos/music. In our Hush Up Text Android Project we provided the user to hide his secret data in the image by using LSB2Bit algorithm.We provide more security as we are encrypting the text first and then encrypting it to the image.

Future Work:

We would like to add the facilities like login for multiple users in further.

Software Requirements:

Jdk, Eclipse, SDK, ADT
