    Abstract: By analyzing a content of a first message, a confidentiality level of the first message is determined. An encryption rule for a first computational complexity level corresponding to the confidentiality level of the first message is selected. The first message is encoded according to the encryption rule. The encoded first message and the confidentiality level of the first message are caused to be sent to a recipient.

    Abstract: Initiating a communication group of devices using device vibration includes encoding a message into a vibration signal using an encoder in a master device, the message including a connection request. A vibration pattern is emitted using a vibration motor by controlling the vibration motor to vibrate with a pattern corresponding to modulations of the vibration signal to send the message through a medium in contact with the master device. A response vibration pattern is received from responding devices using a sensor, the response vibration pattern carrying a response message. The response vibration pattern is decoded with a decoder of the master device to extract the response message from the response vibration pattern. A communication group is established at a host according to the response message for communication between the master device and the responding devices.

    Abstract: Methods, computer program products, systems are provided for securely performing electronic transactions over a network. An acoustic wave signal is received. The acoustic wave signal is encoded with at least an identifier of a payer of a transaction and transaction information of the transaction. The identifier of the payer and the transaction information is then obtained from the acoustic wave signal. A bone conduction characteristic of the payer is retrieved based on the identifier of the payer and based on the received bone conduction characteristic of the payer, the payer is verified. Completion of the transaction is allowed based on the transaction information in response to the payer being verified.

    Abstract: A blockchain of transactions may be referenced for various purposes and may be later accessed by interested parties for ledger verification. One example method of operation may comprise one or more of identifying shipment locations for a product shipment, storing the shipment locations in a local blockchain, transmitting the shipment locations to a remote blockchain, comparing the shipment locations of the remote blockchain with the shipment locations stored in the local blockchain, and verifying the shipment locations of the remote blockchain are consistent with the shipment locations stored in the local blockchain.
