Where is fingerprint data stored?

I've run into an issue where my phone is now accepting anything on the fingerprint scanner as a valid fingerprint, and I'm unable to add new prints, or clear existing ones for some reason. I'm going to try to just delete the fingerprint data before I do a factory reset, but I don't know where it is actually kept on the phone, if anyone has any idea, it'd be appreciated.

Update: I ran logcat *:E and got this when trying to remove fingerprints
07-30 20:30:21.342 960 960 E fpc_tac : fpc_tac_send_get_uint32_cmd failed with retval: -3
07-30 20:30:21.342 960 960 E fpc_fingerprint_hal: int fpc_remove(fingerprint_device*, uint32_t, uint32_t) failed -5, reloading db
07-30 20:30:21.358 960 960 E fpc_fingerprint_hal: int fpc_remove(fingerprint_device*, uint32_t, uint32_t): fpc_tac_load_user_db failed with error -4
