It sounds like you want something more life oriented. It is an interesting idea. With public key cryptography you could securely log and encrypt your every movement. Even if the phone was seized later there would be no access to the data. The private key required to decrypt the data could be kept on the phone encrypted with a strong passphrase or in a completely different secure location.
