While transferring a file from one point to another through Intranet and Internet we need more file secure concepts. Ordinary, file Encryption-Decryption Concepts, which are readily available in java examples are easily captured by middle way itself. So we need more security combination. This project helps to send a file from one place to another in a secured manner. Firstly the target file is encrypted and it is embedded into an audio or video or any media file. The resultant file will be protected by a password. This resultant media file is not changed in its original format and it can be run in the player, we can’t find any encrypted data inside it. This format will be sent through net. In the destination point it will be retrieved only by our software and giving the relevant password. So it is highly secured.

Data Security Using Steganography

  1. 1. Security System Using Steganography
  2. 2. Introduction  While transferring a file from one point to another through Intranet and Internet we need more file secure concepts.  Ordinary, file Encryption-Decryption Concepts, which are readily available in java examples are easily captured by middle way itself.  This project helps to send a file from one place to another in a secured manner
  3. 3. Objective The main objective of this project is SECURITY during file transmission from one end to another end both in Internet and private network. The main concept of Steganography, i.e. Encrypt a file and hide it in another media to invisible it, is maintained by our project such that our target file will be encrypted and embedded into an audio or video file then the resultant video file is send through the network. The front-end screen of this software will be designed in Java using Swing Concepts.
  4. 4. Steganography is the practice of hiding private or sensitive information within something that appears to be nothing out of the usual. Steganography is often confused with cryptography because the two are similar in the way that they both are used to protect important information. Steganography comes from the Greek words Steganós (Covered) and Graptos (Writing). Steganography
  5. 5.  The art of detecting Steganography is referred to as Steganalysis.  Steganalysis does not deal with trying to decrypt the hidden information inside of a file, just discovering it.  To put it simply Steganalysis involves detecting the use of Steganography inside of a file.  The most common use of Steganography is to hide a file inside another file.
  6. 6. Existing System  For Transmitting a file from one point to another many of us are using Encryption only. This will not give that much of security.  While using Steganography for embedding a source file to an another media they are using watermark embedding. It is also have its own disadvantages. The resultant file of this techniques will be change from the source file. Watermark embedding is easily decrypted by the hackers.  Encryption and Embedding only is not give that much of security to our communication.
  7. 7. Proposed System  In our system we are not following the regular encryption, decryption techniques.  We are Introducing a new algorithm Bit-Shift in Random Cycle Order. I.e. totally 4 different types of Bit-Shift algorithms are used randomly to encrypt the data  This Encryption is embedded into an Audio or Video File.  Again It will be embedded into another media. This double embedding increases the level of security.  Password Protection of this entire works give an additional security.
  8. 8. Technologies overview  This project helps to send a file from one place to another in a secured manner.  Firstly the target file is encrypted using an algorithm called Bit Shifting.  The Encrypted file is embedded into an audio file.  The resultant file will be embedded into a video file.  The video file and the whole thing is protected by a password and sent through net.
  9. 9. Modules  Connection manager Module  Merger Module  Extractor Module  Result window Module
  10. 10. Merger Module This Module is front end module and it is designed using swing. This module gets the inputs from sender. The inputs are Audio/ video, Image/Text and secret message file with password. Then merge the all requirements and then send to receiver.
  11. 11. Connection manager Module The merged file can send from sender or server to receiver. The UDP protocol can be use for that networking process.
  12. 12. Extractor Module This module gets the merged file after a password verification. Then extract the merged file and call the result window module to open extracted file.
  13. 13. Result window Module This module displays the original secret file and covered Audio/Video file .
