Image
Avascular Necrosis (AVN) is a condition where blood flow to the bone is reduced, causing bone cells to die. This leads to pain, joint damage, and difficulty in movement, especially in the hip. Early diagnosis and proper treatment can prevent permanent bone damage and improve quality of life.

Role of Cryptography in Information Security |Cryptography Techniques

-

Topics Covered: Role of Cryptography in Information Security.

1.) What is Cryptanalysis?

Cryptanalysis is a technique decoding messages from a non-readable format back to a readable format.

2.) What is Plain text?

Plain text means Clear text/ Original Message. Plain Text can be understood by anybody knowing the language. For Example Communication Language used here: English and Message: Hello Everyone 

Plain Text = Clear Text [the message that can be understood by both sender and receiver and also by anyone else who gets access to that message].

3.) What is the Cipher Text?

Ciphertext means Codified Message / Encrypted Message / Unreadable Message. When Plain Text is Encrypted, the resulting message is Cipher Text.

4.) What is Encryption? 

The Process of Converting from Plain text to Cipher Text. Also known as Enciphering. 

5.) What is Decryption?

The Process of restoring the Plain text from Cipher Text. Also known as Deciphering. 

6.) Elements of a Cryptographic operation. 

7.) Substitution Techniques [caesar cipher]

In the substitution cipher technique, the character of plain text is replaced by other characters, symbols, or numbers.  An example of a Substitution Cipher is Caesar Cipher. 

Caesar Cipher Example:

Replace each letter of the alphabet with the letter standing three places down the alphabet.

 Cuckoo Search Algorithm - Metaheuristic Optimization Algorithm What is Cuckoo Search Algorithm? Cuckoo Search Algorithm is a Meta-Heuristic Algorithm. Cuckoo Search Algorithm is inspired by some Cuckoo species laying their eggs in the nest of other species of birds. In this algorithm, we have 2 bird Species.  1.) Cuckoo birds   2.) Host Birds (Other Species) What if Host Bird discovered cuckoo eggs? Cuckoo eggs can be found by Host Bird.  Host bird discovers cuckoos egg with Probability of discovery of alien eggs.  If Host Bird Discovered Cuckoo Bird Eggs. The host bird can throw the egg away. Abandon the nest and build a completely new nest. Mathematically, Each egg represent a solution and it is stored in the host bird nest. In this algorithm Artificial Cuckoo Birds are used. Artificial Cuckoo can lay one egg at a time. We will replace New and better solutions with less fit solutions. It means eggs that are more similar to host bird has opportunity to de...

 Local Binary Pattern Introduction to Local Binary Pattern (LBP) Q. What is Digital Image? A. Digital images are collections of pixels or numbers ( range from 0 to 255).  Q. What is Pixel? A. Pixel is the smallest element of any digital image. Pixel can be categorized as Dark Pixel and Bright Pixel. Dark pixels contain low pixel values and bright pixels contain high pixel values. Q. Explain Local Binary Pattern (LBP)? A. Local binary pattern is a popular technique used for image processing. We can use the local binary pattern for face detection and face recognition. Q. What is LBP Operator? A. LBP operator is an image operator. We can transform images into arrays using the LBP operator. Q. How LBP values are computed? A. LBP works in 3x3 (it contain a 9-pixel value ). Local binary pattern looks at nine pixels at a time. Using each 3x3 window in the digital image, we can extract an LBP code. Q. How to Obtain LBP operator value?  A. LBP operator values can be obtained by ...
