摘要： A laser-scanning method may include obtaining scan data captured by a laser scanner in which the laser scanner includes a first private key that uniquely corresponds to the laser scanner. The laser-scanning method may include obtaining a first digital signature corresponding to the obtained scan data that is generated based on the scan data and the first private key. The laser-scanning method may include validating the first digital signature using a first public key that corresponds to the first private key and generating a report that summarizes results of the validating. The laser-scanning method may include transforming and aggregating, by a scan data aggregator, the scan data as aggregated scan data and generating a second digital signature corresponding to the aggregated scan data. The second digital signature may be generated by signing hashes corresponding to the aggregated scan data using a second private key corresponding to the scan data aggregator.
