Depending on the context, you might just go for anonymized, meaning that individually-identifiable bits of information have been removed. I would assume sensitive information would include names, birthdays, addresses, GPS-coordinates, and other data which would allow individual people/places/things to be picked out.
anonymize, vt. – to carry out or organize in such a way as to preserve anonymity (Collins English dictionary via dictionary.com)
If the individuals/items about which you are displaying this partially-obscured information have names, then what you have described is anonymization precisely, because it removes any chances of getting back to the names of those people/places/things, from the Latin prefix a- meaning 'no' and the word 'non' meaning 'name.'
Aside: At my place of work, we do a similar processes wherein we remove sensitive information and mark it out with phrases like "sensitive." If you're like me, might hear this activity described as "sensitizing" in an informal context. Although the term actually means 'to make (more) sensitive,' rather than 'to label as sensitive and remove information accordingly,' it gets the point across fairly concisely, since data cannot feel sensations anyhow.
