ABSTRACT:

Errors occur! Even when we do our best to avoid errors, they still happen
from time to time. In particular, there will be errors in data. Errors may
have many causes, for example noise during transmission, malfunction of
magnetic recording devices, etc. Knowing that errors will occur, it is
important to recognize them, that is, detect that our data has errors.
This is done by introducing redundancy in the data.

In this talk we will give an overview of error detecting code, from simple
schemes like parity checks and bar-codes to more advanced codes. We will
introduce measures which can be used to evaluate the performance of error
detecting codes and describe some of the still open problems in the area.

Hong Kong. His research over the years has covered a number of fields:
number theory and combinatorics, formal languages, coding theory,
cryptography. His main research area over the last 25 years has been error
detecting code and error correcting codes. He is co-author of the book
