Thank-you, all for your time and valuable feedback.

Yes, CHECKSUM fails to detect symmetric changes and has therefore been listed only as a "basic" change detection mechanism. The "ideal" one would be HASHBYTES, but it comes at an additional cost - storage.

As mentioned in the article, I would request the kind reader to please go through my in-depth study on the various change and tamper detection mechanisms available where I attempt to evaluate each of the pros & cons of the various methods (Part 01[/url] and Part 02[/url]) .
