  • Publication number: 20230283466
    Abstract: An connection apparatus receives a purchase desire notification including a public key from another connection apparatus via a blockchain network and transmits an encrypted content key acquired by encrypting a content key using the public key to the other connection apparatus via the blockchain network. The other connection apparatus transmits the purchase desire notification to the one connection apparatus and transmits transmission source information representing a transfer destination of the content to the blockchain network. In addition, the other connection apparatus decrypts the encrypted content key from the one connection apparatus using the stored secret key. In a case in which the encrypted content key is received, the blockchain network changes an owner represented in owner management information to the transfer destination.

  • Patent number: 10922632
    Abstract: A client device accepts event information for which a people flow prediction is to be performed from a user and the client device inputs the accepted event information to a people flow prediction device. The people flow prediction device outputs a result of people flow prediction responsive to the input event information to the client device and the client device displays the result of people flow prediction to the user. The people flow prediction device performs a people flow prediction by temporally and spatially allocating an event attendance which has been input from the client device to pathways, each connecting a transport facility at which a people flow originates and an event site. Consequently, it is possible to predict a flow of people who attend an event or the like, the people flow differing from that in an ordinary situation, without need to input real-time data.
