Image Steganography Project in Python

A steganography technology means that securing sensitive information using advanced hiding methodologies. By the by, it is not limited to simple text insertion over image files. In addition, it supports multimedia information like binary files, voice, communication channels, text, etc. Further, steganography techniques are expected to fulfill below specified requirements.

Significance of Steganography

  • Once data is embedded into stego object for the purpose of hiding, data should ensure the integrity
  • Embedded stego object should not be modified to stripped eye view
  • If there is a change in stego object, then it should not create an impact on the watermark
  • In overall, the attacker can only know that stego object comprises hidden data

From this article, the current scholars can gain essential fundamental information of developing Steganography Project in Python!!!

As a matter of fact, steganography is a practice of transmitting secret/data messages by applying secret writing approaches like cryptography. The main reason behind the usage of steganography is providing privacy over data. For more clarity, here we have presented the entire steganography process in the form of a formula.

Steganography Formula

Stego_Medium = Stego_Key + Cover_Medium + Hidden_Info

In the above formula, a file that holds Hidden_Info (hide data) and Stego_Key (encrypt data) is called as Cover_Medium. Then, the output file is called as Stego_Medium. Here, both Cover_Medium and Stego_Medium files are of the same file format as audio/image. In fact, here we have focused on image-type files as Stego_Image and Cover_Image.

A subset of encryption is said to be steganography. Although the encrypted file is decrypted, steganography is used to hide information. To implement steganography, python is the most used resourceful software which is composed of a large number of libraries. Here, we have given you the procedure for encrypting and decrypting in the steganography project using python.

Image Encryption

  • Get the image and write the text
  • Transform information into ASCII array
  • Determine required pixels count which is equivalent to 3 times more than the array size
  • Find required rows count which is equivalent to pixels count per width
  • Pass through the image row-wise by following the below limitations.
    • First verify the number of pixels traversed
    • When the bit is 1, then pixel value is even number, So, subtract by 1 for odd number
    • When the bit is 0, then pixel value as an odd number. So, subtract by 1 for an even number
    • Record the number of letters based on the count variable.
    • When the index is equal to 7, check whether the next character is present or not
    • If it is present, then set EOF bit as 0 and continue
    • If it is not present, then set EOF bit as 1 and end
  • In overall, we have effectively completed encryption of image into a file

Image Decryption

  • Get and open the encrypted image and transform the image into a numpy array
  • Extract data from an image by following below instruction
    • Each pixel per row incorporates 1 bit of data. As well, it is inserted into data variable by using for loop
    • Verify whether EOF character is attained
      • If attained then break the for loop
      • Else, continue
    • Store ASCII bits in the sequential format in the data variable
  • Once ASCII bits are acquired, these bits are collected together as letters (8 groups)
  • Store letters in data variable that is connected by a python-based joint command
  • In overall, we have effectively completed decryption of the image and displayed a message on the screen

Now, we can see the primary libraries that are used for Steganography Project in Python. Here, each library has special functions to execute the specific operation of steganography. For instance: numpy deals with numerical computation and stegano deals with steganography methods. Our developers have sufficient skill to practice not only these libraries but also in other vital python libraries. Further, we also have improved knowledge on incorporating external toolboxes in the case of requirements.

Python Libraries for Steganography Projects

  • PIL
  • CV2
  • Numpy
  • Stegano

All the above-specified modules are basic necessities to install for general steganography project in python. So, here we have given you some important python commands for installing the required modules. Likewise, we also provide installation guidelines for installing other libraries/packages of your project at the time of project delivery. In addition, we also provide you with project execution video, running procedure, screenshots, software requirements, and hardware requirements.

The significant python-enabled module used for steganography is Stegano. As mentioned earlier, steganography is one of the methods to write a secret message by the sender and transfer it to the receiver.  In other words, it protects the message from suspects. As a result, stegano functions are sure to hide messages in the absence of encryption. Further, it is also incorporated with cryptography. Moreover, pipx installs scripts are also incorporated in individual virtual envs for the benefit of your proposed project.

Steganographic Methods

  • Palette-based image steganography

    • It allows data to encrypt image palette with least significant bits instead of the carrier
    • It has minimum data-carrying capacity
  • Discrete Cosine Transform (DCT) Steganography
    • It is also a part of LSB steganography which uses JPEG images to carry a payload
    • It secretly encrypts the information within the co-efficient of DCT
    • It relatively has minimum capacity for data carrier. Since the coefficient values (1 and 0) are unable to change
    • It makes data not encrypt while co-efficient values are taking place
  • Wideband Techniques
    • It has frequency hopping technique to use pseudorandom law for altering carrier signal frequency
    • It has pseudorandom sequence technique to use the pseudorandom signal for modulating the secret carrier signal
  • Payload Embedding
    • It enables payload to encrypt in the carrier and decrypt in delivery by common technique
    • It has orthogonal embedding methods which make payloads encrypt independently to the same carrier

Compare to 2D images, the 3D image offers several information and real-time experience. In this, there are two primary steps in converting a 2D image to a 3D image. With an intention to form stereo pair, it uses depth-assisted rendering (new image) and depth estimation (2D image). In the process of rendering, it is simple to generate good-quality images. However, the main issue is estimating depth from video frame / single image. So, it is required to concentrate on depth recovery more than depth-assisted rendering.

Although there are several techniques in video steganography, there is no optimal technique for satisfying all requirements. Here, we have given you some important constraints that optimal technique is required to achieve. By maintaining a good trade-off, scholars are attempting to satisfy all these requirements. Likewise, we also promise you to fulfil your project needs inefficient ways like advanced techniques.
