Authentication method, authentication system and authentication program

摘要

A data server to authenticate a passenger anonymously and allow an outside service to provide a service on the basis of this authentication. A passenger in an automobile uses a portable terminal with an acceleration sensor to send the acceleration sensor log in the portable terminal to a data server. The data server calculates the degree of similarity between the acceleration sensor log and time-series data related to acceleration obtained from probe data acquired from the automobile, and verifies that the portable terminal is indeed inside the automobile by confirming that there is a sufficiently high correlation between the log and the time-series data. The data server provides an access permission code to the portable terminal in response to successful acceleration authentication. The portable terminal provides the access permission code to an outside service, and the outside service accesses probe data in the data server using the access permission code.

主权项

1. A processing system having a function for collecting probe data from an automobile, the processing system comprising:
a memory; a processor communicatively coupled to the memory; and a data server, communicatively coupled to the memory and the processor, further comprising: means for receiving acceleration time-series data from a portable terminal equipped with an acceleration sensor inside the automobile; means for extracting time-series data related to the acceleration of the automobile from the collected probe data; means for calculating a degree of similarity between the acceleration time-series data received from the portable terminal and the time-series data related to acceleration in the probe data; means for generating an authentication code in response to calculation results from the means for calculating the degree of similarity indicating a degree of similarity equal to or greater than a predetermined level, and for sending the authentication code to the portable terminal; and means for permitting a server for an outside service to access the probe data in response to receiving the authentication code from the server system of the outside having received the authentication code from the portable terminal.
