Today, the security is getting the major attention due to the increased use of internet. As the use of internet is increased, the rate at which the data is exchanged per day is also increased. The data that is exchanged every day may become the victim of hackers. To deal with this problem one of the effective solution is the Steganography. The Steganography is a way to hide secret information behind an innocent cover file, such that the existence of information is not usually recognized.
The rapid growth of internet makes the daily life much easier for human beings. Some examples which illustrate the use of internet are –the most used online shopping facility, online bill payment, online money transactions, booking online tickets, online recharge etc. The other part of facility which mostly affected the human lives is social networking sites like facebook, twitter, instagram, what‟s app etc. Due to this facility the peoples are sharing their important information, documents with the other person. People share their private and secret data with the other person through the internet. Transferring private data through internet may become a victim of hackers. So security is upmost important while sending the data through internet.
The word steganography is derived from the Greek words steganos (meaning hidden or covered) and the Greek root graph (meaning to write).Steganography can be used to conceal almost any type of digital content, including text, image, video or audio content; the data to be hidden can be hidden inside almost any other type of digital content. The content to be concealed through steganography -- called hidden text -- is often encrypted before being incorporated into the innocuous-seeming cover text file or data stream. If not encrypted, the hidden text is commonly processed in some way in order to increase the difficulty of detecting the secret content. In steganography we also cryptography for encryption or decryption of data.
So to overcome this problems we used zip-steganography-using-java in this we use the file compressing alogrithm through which we can keep our data safe by compressing it and hidding behind the video this is more secure way to keep our data safe and secret through this software we compress our data file with the video and send it securely. In this we are using the video to hide our data.
Steps to Encrypt the data:-
- First we select the data file which we want to hide.
- Then we select the video file behind which we want to hide the data.
- Then we click on the encrypt button
Steps to Decrypt the data:- 1.To decrypt the data we select the encrypted file from the folder. 2.Then we click on the decrypt buttton .
Note:- To see the Encrypted or Decrypted files you have go to the encrytion or decryption folder which are automatically made in your drive.
