All the users' electricity consumption data sent by smart meters in the same user area are firstly aggregated by the fog node to generate a fog-level aggregate ciphertext. Then the fog node further generates a digital signature for the fog-level aggregate ciphertext and sends these data to a cloud server for long-time storage. The cloud server stores all the aggregate ciphertexts and digital signatures received from different user areas in its database, and provides data query and statistical analysis services for the control center of smart grids. On the premise of without violating users' privacy, the cloud server could provide enough information for the control center, enabling it to compute the sum, arithmetic mean and variance of all users' data in specified areas in a privacy-preserving way. |

Blockchain architecture conforming to general data protection regulation for management of personally identifiable information
Incidents involving confidentiality and vigilance against user privacy invasions raise doubts as to current third-party data collection procedures. Personally identifiable information (PII) is being abused for medical data breaches, identity theft, spam, phishing, cyber spying, etc. A great amount of data is flowing from users to companies for prediction and analysis of data-centric markets. It is thus difficult to track PII flow and genuineness. Blockchain technology, which is an “immutable” distributed ledger, can efficiently track PII exchange, storing, and distribution. In contrast, the EU general data protection regulation (GDPR) in progress claims “a right to forget” and a right “to delete”. However, the present specification proposes an off-chain blockchain architecture using both a local database and a distributed ledger to guarantee a trustable PII life cycle. |

Resource response expansion
The described technology is directed towards returning expanded data, beyond the data that was specifically requested, to a client, in order to reduce or eliminate likely subsequent requests for more data. Client requests for data items are processed by expansion rule logic to find an expansion rule set (e.g., file) corresponding to the identified data item. The rule set is used to expand requests for certain data items into expanded requests that return more data items than those requested. Client devices receive, cache and (often) use the cached expanded data items, which thereby reduces the overall number of requests to the data service. Expansion rules may be based upon observations (e.g., machine learned and/or manual) of request patterns, so as to reasonably predict which data item or items clients will likely next need, and return those as expanded data items in anticipation of their need. |
