Is it possible to detect changes in the base64 encoding of an object to detect the degree of changes in the object.

Suppose I send a document attachment to several users and each makes changes to it and emails back to me, can I use the string distance between original base64 and the received base64s to detect which version has the most changes. Would that be a valid metric?

If not, would there be any other metrics to quantify the deltas?
