Dear S.K.Jha,
This is Jennifer Bellamy here. Recently I have taken up Scrum Master Certification. Based on my earlier research I can suggest few names.There are three hugely regarded certifications and they are from scrum.org, scrumalliance and scrumstudy.com and all are approved by all leading companies.
As mentioned by Matt Daniels, there is no certifying body for Scrum Certification.
