Placing checkboxes inside of text input fields

Okay so i am currently working on an intern application. One of the tasks is to create a new entry for a specific contact person.

After entering all the information, the user has to decide if the entered data (Phone Number, Mobile, Fax) will be visible online on the website (people can look up contact persons on the website)

Since the entered data wont be really long i thought about putting a checkbox in each of those fields but im not really sure if there is a better solution.

I don't want to put the checkbox below each field since this wastes a lot of vertical real estate.

Whats your opinion?
