<u><em>Differences between barcode reader and character recognition devices:</em></u>
Barcode Reader or Barcode Scanner:  
- Barcode Scanner scans the data by brightening the barcodes usingSensor 
 - The analog signal  is then converted into digital signal by Converter. 
 - The Decoder calculates the converted data and sends valid data to the computer.  
 
Character Recognition Devices (OCR):
- OCR scans the physical document and converts them into two-coloured format.
 - The darker and lighter area are identified as characters and blanks respectively. 
 - The common methods used are: Pattern Recognition and Feature Detection.
 
 
        
                    
             
        
        
        
The data that is transmitted in plain text is option D: cryptographic failure.
<h3>An established plain text only assault is what?</h3>
The known-plaintext attack (KPA) is a cryptanalysis assault type where the attacker has access to both the encrypted and plaintext versions of the data (also known as a crib) (ciphertext). These can be used to reveal additional hidden information, including code books and secret keys.
Therefore, Plaintext in the context of cryptography typically refers to unencrypted data that is being prepared for input into cryptographic techniques, typically encryption algorithms. Typically, unencrypted data transmission or storage falls under this category.
