I was reading article on JWT web token as an access token that is being response to the user. Some of it mention that the web token should be able to be decoded by the user.
Does it means that it is not a good practice to decrypt the entire web token? For example, I suppose to return following JWT web token to user where this piece of information can be decoded.

However, I feel that I do not want to let user able to decode his/her access token, so I use another encryption algorithm to encrypt everything into another form as follow and pass back to user.
So, I would decrypt this new text when I'll get this access token in the server and decode it.
Is it recommended to do it this way if I do not wish to expose some of the value available in claim (such as user id) to the user? If not, what are the alternatives?
