Need some ideas to achieve data marketplace through hyperledger

Question

I am trying to create a data marketplace where a party can transact with other parties, agree on the set of terms and sell data from one to another.

Here data security is of utmost concern. A party makes data available on the hyperledger, this data should be secured and no one should get hold of it. If an interested party wants this data, they have to transact with data owner party and agree on the set of terms. Only then the interested party will get the data. And now only two parties should have hold of this data. Everyone else should not get hold of it.

I would like to know what components of hyperledger can be used here. I have an idea of private data concept in hyperledger, but not sure how and where it would fit.

Would love to hear some comments from experts regarding this.

Edit: I am thinking of using private data for data sharing securely whenever two parties agree for the transaction. And for that I am thinking of upgrading chaincode every time two parties agree on set of terms for data sharing. Only thing concerns me is that every endorsing peer needs to install and upgrade the new version of chaincode simultaneously and that could be undesirable, because data exchanges on this platform could be very frequent.
