Steganography:
Steganography is the method to hide the data within data, image, or audio files. It is not a form of cryptography, it is another way of securing data and information in transit. The word steganography is from Greek word and the meaning of the word is “secret writing”.
Usage of steganography:
- It protect the message from third party and protect the data alteration.
- Enhance the secrecy of data.
- Using steganography the user can protect the secret communication on web to avoid transmission.
- Steganography can used in secret key and public key.
- The data can be hidden in text, image, and audio files. So it is used in many applications.
Steganographic tools:
The web shows many steganographic tools to hide the secret message in image and audio files.
These tools are:
- Xiao steganography
- Trojan
- OpenPuff
- Text Hide
- LSB steganography
- QuickStego, etc.
One of the steganography tool “LSB steganography” is downloaded for encryption. The following screenshot shows the way of this cryptosystem.

- The tool has menus to open and insert the files for encryption.

Go to “image” menu, browse the image and given the input with encryption key.

- Do you know how system image recovery works?arrow_forwardWhat exactly is system image recovery, and how does it work?arrow_forwardQuestion 6 Compute 3-level image pyramid and display the results. Please use Matlab solve this problem. Any .JPG file is fine. Full explain this question very fast solution sent me step by steparrow_forward
- Provide the detail explanation of all steps involve from capturing a scene to the acquisition of a digital image? All steps are important?arrow_forwardWe begin with resizing the image. Resizing images is something you will want to do frequently when working in multimedia. Click on Image | Resize and set the dimensions to 640 x 480 (be very careful to set the image to 640 x 480 pixels, not 640 x 480 percent of its original size, or you will create an extremely large image!). Why would you use Resize and not Canvas Size?arrow_forwardWhy convolving the high-resolution image with a larger PSF,then subtracting the two images, produced a similar result.Please explain this in terms of formulae and concepts; “theimage looked the same, so the result was the same” is not anacceptable answer.arrow_forward
- Compare and contrast the benefits and drawbacks of the different image representations. If you only had a limited amount of computer resources, which format would you choose?arrow_forwardIs it easier for you to identify someone using their fingerprints, speech intonation, face features or retinal patterns? Which do you think will be the most popular in the future, and why do you think so?arrow_forwardThe first-ever image of a supermassive black hole was captured using approximately 4.5 petabytes of data. How many 1 Terabyte storage devices are needed to capture it? (Note: 1 petabyte = 1 x 10^15 bytes)arrow_forward
- What is the relationship between frame rate and line rate and image quality?arrow_forwarddetermine the sequence of execution of processing by computing for the need of each process, refer to the image and answer the item below:1. What is the need of PO. No need to include whitespaces in between numbers * 2. What is the need of P1. No need to include whitespaces in between numbers * 3. What is the need of P2. No need to include whitespaces in between numbers 4. What is the need of P3. No need to include whitespaces in between numbers * 5. What is the need of P4. No need to include whitespaces in between numbers * 6. What is the first process to be executed? * 7. What is the second process to be executed?* 8. What is the third process to be executed? * 9. What is the fourth process to be executed? * 10. What is the fifth process to be executed? *arrow_forwardWhat is system image recovery?arrow_forward
