Hundred-Year-Old Mystery: Indus Valley Script Remains Uncracked

Rajesh PN Rao is a computer scientist, and he has been receiving email almost every week, and in those emails, people claim that they have cracked the code, and they know what the ancient Indus Valley script says and what is written in it. 

 Those people who have emailed Rajesh PN Rao are based in India, or they belong to an Indian family, or they have a background of Indian origin and claim that they have solved the puzzle. However, things got more serious when the CM of Tamil Nadu, MK Stalin, offered a price of US 1 million dollars to whoever cracks the code of Indus Valley script . 

However, the mystery is still unsolved, and no one has cracked the code yet. There have been 100 years of efforts by archaeologists and even linguists, but still it was not cracked, and it is still undeciphered. There have been attempts to crack the code by machine learning, but still it seems that this will remain undeciphered.
