Unique identifiers for publishing scientific articles

The announcement in the Journal to aid Authors with non-Latin names by allowing them to include their name in original lettering is an excellent step in the right direction but one which does not go far enough. In the new electronic age (and even before), a major problem for scientists searching databases are the many very common Latin and non- Latin names such as Ng, Smith, Chen, and Jones to name a few. My suggestion is that Authors be given the opportunity to register a unique identifier that will remain the same when they move institution, marry, or change their name for any other reason. This 'name' would be any unique alphanumeric and would feature in an article in a place that would permit database searching such as keywords, abstract, or similar. Such a move would greatly advantage scientists with common names whose work would now be available for rapid and selective searching.
