Hi Nijiole, this is an english speaking forum. I translated your question accordingly. When you have a publicly recorded data (from the blockchain), the whole point is that you are not able to get the private key, otherwise the security model of the bitcoin would be broken. Also your question is very short, maybe you want to extend it, to get better answers (see here: https://bitcoin.stackexchange.com/help/how-to-ask)

There are irreversible hashing algorithms involved so that there is no way to get the private key from a transaction.

Otherwise, everyone could send foreign bitcoins away.
