The Luhn algorithm popularly known as MOD 10 algorithm is a simple checksum formula designed to protect against accidental errors that normally occur number generation systems and for malicious attacks. Most credit card companies and governmental identification numbers use the algorithm as a simple method of distinguishing valid numbers from collections of random digits.
It is not also intended to be a cryptographically secure hash function. This takes a look at the Luhn algorithm or MOD 10 algorithm and its implementation in a suitable programming language called the C programming language. It intended to be a simple, modern, general-purpose, object-oriented,programinglanguage. The algorithm is in the public domain and is in wide
Luhn algorithm credit card validating c# today.
It is not intended to be a cryptographically secure hash function. It was designed to protect against accidental errors, not malicious attacks. Most credit card and many governmental identification numbers use the algorithm as a simple method of distinguishing valid numbers from collections of random digits.
Credit card refers to an electronic miniature card that contains secret information about the identity of the card holder.
A credit card is then used by the identifier to transact business across various electronic platforms like Amazon. Credit cards contain vital information in the form secret codes that requires processing before payment can be made or translation before an electronic platform can authenticate and validate the credit card number before transaction takes place.
First of all, the first destination is the payment gateway then to the appropriate processor.
The processor submits your credit card information to the credit card interchange system. After, routing your credit card information through the credit card interchange system, then you are routed again to the issuing bank where your information is verified for available funds in your credit card account after which your account is credited and then the transaction is completed. The Luhn algorithm is the most fundamental structural algorithm for validating credit card information which is used by most credit card companies even though other complex algorithms also exist for validating other types of cards.
Typically, all credit card numbers are numeric and the length of the credit card number is between 12 digits and 19 digits. Credit cards mostly issued Dinners Club contains 14, 15,or 16 digits while 15 digits relates American Express, 13 or 16 digits are handled by Visa and finally 16 digits credit card is handled by Master card. Again, another related paper focuses on how credit card fraud detection systems could be enhanced by employing machine learning methodologies. These methodologies or techniques as it were enables credit card fraud detection systems learn from the behavioral purchasing patterns of suspected fraudsters and criminals.
The machine learning system is able to tract ,solicit and collate information about a suspected card fraudster and generate a report to the monitoring system also called the machine learning system. According these two authors, due to the rampant nature of credit cards thefts there is the need for innovation in the development of systems that are intended to authenticate and validate credit cards before they "Luhn algorithm credit card validating c#" used for any electronic transactions.
Credit cards algorithms are also needed to be improved and specifying new schemes and processing algorithms are sophisticated in design and provide the form of security for credit card users Tao Huixian, The cardinal objectives of this paper are as follows: Explore the anatomy of credit cards. Explore the Luhn algorithm popularly known as MOD 10 algorithm. Translate the Luhn algorithm into credit card validation program written in C programming language.
In the second phase, a different kind of algorithm is designed and implemented in C programming language. It designates the category of the entry which issued the credit card. It will identify the institution that issued the credit card. Annex — 34xxxx, 37xxxx 4. Visa — 4xxxxxx 5. Master card — 51xxxx — 55xxxx 6. Discover — xx, xxx, 65xxxx 7. Check digits Last digit is known as the check digit or checksum. It is used to validate the credit card number using the Luhn algorithm credit card validating c# algorithm MOD 10 algorithm.
Background of Luhn Algorithm The Luhn algorithm or Luhn formula, also known as the modulus 10 or MOD 10 algorithm is a
Luhn algorithm credit card validating c# checksum formula used to validate a variety of identification numbers, such as credit card numbers, National Provider Identifier numbers in USA and Canadian Social Insurance numbers and the rest of the world. When implementing electronic commerce eCommerce applications, it is best practice validating credit card numbers before sending the bank for any electronic transactions.
Using the Luhn algorithm to validate Credit Card numbers For example consider: Starting with the check digit double the value of every other digit right to left every second 2nd digit.
If doubling of a number results in a two digits numbers add up the digits to get a single number. Now add the undoubled digits to the odd places. Add up all the digits in this number.
If it is not divisible by 10, the number is not valid. If it is not divisible by 10, the number is invalid. The C programming language is a standard programming language that cut across different platforms and so it is standard-based and allows for flexible and convenient software development methodologies.
The credit card validation program is able to ascertain the validity of credit card number based on the Luhn algorithm. The process of validating the credit card numbers follows. Starting from the first digit, you double the value of every Luhn algorithm credit card validating c# digit right to left, every second digit then if by doubling of a number result in a two- digit number, you add up the digits to get a single digit number. Furthermore, add up all the digits in this numbers and finally if the final sum is divisible by 10, then the credit card number is valid and if it is not divisible by 10, that particular credit card number is invalid.
The Luhn algorithm implementation in C programming language cut across all kinds of credit card numbers that is used for making orders and purchases of items from electronic platforms or sources. Finally, this work served as an improvement based on the previous work done by the above-mentioned authors and sought to pave the way for new researchers to look more into credit card validation. Any programming novice can easily work around the code to generate the same program using a different programming language.
In the other hand, the C sharp credit card validation program uses a universal standard and its program that is meant to check the credibility and validity of the credit card in question and also does not detect whether or not, the true identity of the credit card holder because that is not the objective of this paper. The main aim of this paper is to design an algorithm in C programming language that would validate the correctness of any credit card number. The Luhn or MOD 10 algorithm provides the most fundamental structure for the purpose of Luhn algorithm credit card validating c# the correctness of credit card numbers.
The Luhn algorithm provides a suitable foundation for implementing it in an object- oriented programming language.
