In connection with personality, 'Identität' (identity) is often used with verbs like 'feststellen' (to establish), 'prüfen' (to check), 'verbergen' (to hide), or 'preisgeben' (to reveal).

profile
'das Profil' and 'die Identität' both have to do with how a person or organization is recognizable. 'das Profil' usually describes specific information, characteristics, or areas of focus that someone presents outwardly. 'die Identität' is deeper and means who someone really is or what makes someone unique. The words can be confused because a profile can show parts of someone's identity. But a profile is more of a representation; identity is the actual self or the totality of one's characteristics.
