Identification Numbers and Check Digit Schemes

Student: Talia Schwartz*
Mentor: Hema Gopalakrishnan
Major: Math 

Identification Numbers are used to authenticate individual items, specific products, people, accounts or documents. In this talk, we will look at specific identification numbers such as the Airline Ticket Identification Number, and the types of transmission errors that can occur.  To catch these transmission errors, we use check digit schemes. We will explore the mathematics behind some check digit schemes and their efficiency in catching various types of errors.
