Authorization issue

Hi Experts,

We have one HR authorization profile created for all the users and its mandatory for every user, when we are assigning this profile to the users all the users are able to see the salary data in the system, so client asking to restrict this data(read & write). when we are trying to restrict at the infotype level the Authorization profile overwriting it and restriction at infotype level is not working.

Please suggest me which way we can do this

Thanks,
