I would like to ask if you know any home based work (typing or data entry) here in Dubai. I have seen many ads but kinda sceptical about it with all the scams lurking around, we can never be sure.

No, sorry I do not know of any home based work but this is an ideal question to put on our expatchat forum as I am sure some of our knowledgeable readers may have an answer for you.  I would also urge you to take time to check with the Ministry of Labour  the legal implications ie do you need a labour card.
