I work in the research department of a small company. There are two people with access to the research database, me and my colleague. The research database contains anonymized data.
My colleague is the daughter of the company's chief executive. Besides access to the research database, she also has access to another database which contains some private and identifiable information (PII).
Recently the chief executive granted me access to the PII info on a need-to-know basis. That is, I can arrange for additional data to be pushed to the research database. However, her daughter seems to be quite uncomfortable with her mom's decision. When I arranged for additional data to be sent to the research database, my colleague spoke to the database administrator, resulting me getting less data than what I had asked for. I got the bare minimum data I needed to do a reasonable project (as opposed to an excellent project). My project became much more time consuming (though it wasn't impossible). I was also able to draw less strong conclusions because I had less data to work with.
I surmise that my colleague has concerns about data security. I don't know the exact reason, but it could be that she has seen the hard work her mum has put in to build the company, and thus is super cautious about data security.
How can I win over my colleague's trust?
