How to make card or column on the board with permission for only certain members?

[Sergey Minevich]

I have some "secret" tasks for different team members. How can I make cards which are hidden for other board members and are available only for certain members which I can choose?

Hi Sergey,

Crystal from Trello Support here! 

Right now that isn't a feature available within Trello but I will be sure to let the team know that it's something you'd like to see! We appreciate you taking the time to let us know!
