What is Blum Code?

Blum Code: An Overview

Blum Code is a specialized error-correcting code invented by Manuel Blum in 1954. It is a type of lossless data compression algorithm designed to correct errors introduced during data transmission. Blum Code operates on the principle of bit-packing, where multiple bits are combined into a single unit, known as a codeword.

One of the notable features of Blum Code is its ability to correct a limited number of errors without the need for retransmission. This is achieved through the incorporation of redundant information within the codewords. When a codeword is received, the redundant information is used to identify and correct any errors that may have occurred during transmission.

Blum Code is widely used in various applications, including data storage, data transmission, and communication systems. Its ability to correct errors makes it particularly suitable for scenarios where data integrity is crucial, such as in the transmission of financial transactions or medical records.
