Abstract
Provided is an information processing apparatus including a processing unit configured to evaluate an evaluation target on a basis of target data regarding the evaluation target acquired from blockchain data circulated on a peer-to-peer network.
Claims11
An information processing apparatus comprising:
- processing circuitry configured to:
- retrieve, from a peer-to-peer network circulating blockchain data and using an address generated from a public key, an encrypted test score of a user, the encrypted test score included within a plurality of transactions linked through one or more blocks of data, the public key being generated from a secret key, the one or more blocks of data being designated by the address,
- decrypt the encrypted test score using a cryptographic key, and
- calculate an evaluation score of the user based on the decrypted test score,
- wherein the address is used to identify the plurality of transactions to retrieve the encrypted test score, and
- wherein the one or more blocks of data designated by the address are not decrypted where there is no cryptographic key corresponding to the public key.
3 more elements
An information processing method to be performed by an information processing apparatus, the information processing method comprising:
- retrieving, from a peer-to-peer network circulating blockchain data and using an address generated from a public key, an encrypted test score of a user, the encrypted test score included within a plurality of transactions linked through one or more blocks of data, the public key being generated from a secret key, the one or more blocks of data being designated by the address;
- decrypting the encrypted test score using a cryptographic key;
- and
- calculating an evaluation score of the user based on the decrypted test score,
- wherein the address is used to identify the plurality of transactions to retrieve the encrypted test score;
- wherein the one or more blocks of data designated by the address are not decrypted where there is no cryptographic key corresponding to the public key.
3 more elements
A non-transitory computer readable medium having instructions stored therein, which when executed by a processor in a computer causes the processor to execute a method comprising:
- retrieving, from a peer-to-peer network circulating blockchain data and using an address generated from a public key, an encrypted test score of a user, the encrypted test score included within a plurality of transactions linked through one or more blocks of data, the public key being generated from a secret key, the one or more blocks of data being designated by the address;
- decrypting the encrypted test score using a cryptographic key;
- and
- calculating an evaluation score of the user based on the decrypted test score,
- wherein the address is used to identify the plurality of transactions to retrieve the encrypted test score, and
- wherein the one or more blocks of data designated by the address are not decrypted where there is no cryptographic key corresponding to the public key.
