Authentication and Non-repudiation of Data

COMPUTER SYSTEM VALIDATION (CSV)
1

Hi All,

I wonder can anyone give me some easy to understand explanations? I am going to validate a database shortly and have been ‘reading up’ on what to look out for, in the Risk Assessment. I read an article recently and it talked about Authentication of Data and Non-repudiation of Data. Can anyone tell me what the difference is.? does one have something to do with printed out copies etc?

thanks
NK

Hi,

You may refer the terms as
Data Authentication : A process used to verify data integrity, e.g., verification that data received are identical to data sent.
Non-repudiation of data : Non-repudiation refers to a state of affairs where the purported maker of a statement will not be able to successfully challenge the validity of the statement or contract. The term is often seen in a legal setting wherein the authenticity of a signature is being challenged. In such an instance the authenticity is being “repudiated”.

Yes, Printed copies may be a methodology for verification & future evidence.

Happy Reading !
