An online system receives impression data from one or more content publishers. The impression data describes impressions provided to users of the online system on behalf of an agent. The online system selects a randomly selected number of impressions in the received impression data. The online system generates an impressions block by encrypting impression data that describes the selected set of impressions using a unique cypher, and adds the impressions block to a blockchain. The online system further generates a cypher block by encrypting the cypher and an identifier of the impressions block to which the cypher applies using a public key provided by the agent to the online system. The online system adds the cypher block to the blockchain. The agent can recover the cypher from the cypher block based on a private key, and the agent can then recover the impression data using the recovered cypher. Link to Full Patent
