Different databases can have different identification numbers for the same author. Combine this with the fact that different databases may have different publications and different citing articles within it, and you create the opportunity for missed citations. This greatly improves the chance for the value of your h-index to be negatively affected.
Researcher profiles and IDs can be used to:
There are a variety of different sites that allow you to create and maintain an academic profile:
ORCiD - enables you to obtain a unique 16 digit identification number that can be used to tie you to your work. ORCiD enables communication across multiple platforms, including Scopus and Web of Science's ResearcherID.
Scopus Author Identifier - creates an Author Profile with an associated Author Identifier, and associates you with the publications that you have authored. Allows you to request changes when you notice inaccuracies in your Author Profile. Scopus also provides the Scopus2Orcid option as a way to link your Author Identifier information with your ORCiD identification number.
Web of Science ResearcherID - add publications that you have authored to a free profile that you create. You can then use ResearcherID to calculate your h-index based on these publications.
Google Scholar Citations Profile - allows you to create a profile, search Google Scholar for articles you have published, and calculate your h-index based on the list of publications you create.
Microsoft Academic Search - search for your name. You may be offered a choice between people with the same name, but working at different institutions. You are provided an h-index and the articles used to arrive at that number.
arXiv Author ID - open access repository (Physics, Mathematics, Computer Science, Quantitative Biology, Quantitative Finance & Statistics)
Academia.edu - allows one to create a profile, share papers and get analytics on the profile and papers

Many authors have similar names. Scopus Author Identifier functionality distinguishes between these names by assigning each author in Scopus a unique number and grouping together all of the documents written by that author.
This feature is especially useful for distinguishing between authors who share very common names like Smith or Wang or Lee.
Additionally, author names in Scopus can be formatted differently. For example, the same author could appear in one document as Lewis, M; in another as Lewis, M.J; and in another as Lewis, Michael. Scopus Author Identifier functionality matches the documents of this author and groups these name variants together, so that authors, even if cited differently, are identified with their specific papers.
This helps you find and recognize an author, despite variations in name spelling.
