Thus images can be read off the computer display screen for decoding which means that a phone`s browser can directly pick up lengthy web addresses without having the user typing in any text.

Computer researchers at the Stanford Security Laboratory have created a computer program to decode audio CAPTCHAs on website account registration forms, thus revealing a security flaw that leaves ...

To break the Enigma code during the Second World War, British computer scientist Alan Turing developed a mathematical model to unlock the cipher faster than any human. Today, a group of University of ...

Decoding techniques for product and staircase codes represent a dynamic research area in error-correcting codes, underpinning robust data transmission and storage applications.

Read and generate QR codes for products, URLs, vCards, phone numbers, calendar events, and more with this fun and useful app.

Polar codes represent a seminal breakthrough in error-correcting coding, enabling communication systems to approach the theoretical capacity of a channel with low-complexity decoding methods ...

An optimized min-sum algorithm for LDPC code is proposed in this paper. In this algorithm, unlike other decoding methods, an optimization factor has been introduced in both check node and bit node ...
