  • Patent number: 10680820
    Abstract: A method of creating and recovering digital wallet is implemented using a storage device and a connected device that are connected to each other. The storage device has a private key stored thereon for confirming a digital asset transaction, and includes an information conveying unit, an operation interface, a processor and a security element. The method includes following steps: a user uses the connected device to generate and transmit a digital wallet creating request to the security element via the processor; the security element verifies there is not any digital wallet stored thereon and accordingly creates a digital wallet; the processor requests a recovery mnemonic from the security element and provides the same via the information conveying unit for the user to back it up; and the connected device obtains and decodes an encoded asset message stored in the digital wallet to create a piece of public digital wallet information.

  • Patent number: 10555173
    Abstract: A pairing authentication method includes the steps of installing application software on first and second electronic devices to create first and second public keys thereon, respectively; connecting the first electronic device to a closed storage device for the former to generate a checking key; storing the first public and the checking key on a security chip of the closed storage device; connecting the second electronic device to the closed storage device for the former to generate an authorization key that matches the checking key, and transmitting the second public and the authorization key to the closed storage device; and the closed storage device verifying the authorization key matches the checking key and storing the second public key on the security chip. Therefore, only a cardholder knowing the checking key can use the closed storage device and no risk of asset theft exists if the closed storage device was lost.

  • Patent number: 10459714
    Abstract: A method of updating firmware of closed storage device includes the steps of connecting an electronic device to a closed storage device having built-in first and second memories and bootstrap loader, and the first memory storing a first application that is set by the bootstrap loader as a default boot loader; the electronic device downloading a second application having a different version from the first application and setting the first memory to a locked state; the electronic device transmitting the second application to the second memory via the bootstrap loader and the second memory is updated when the second application is written thereinto; and the bootstrap loader setting the second application as the boot loader. The two applications of different versions in the closed storage device are updated alternately, and the old application can still be used as the boot loader when the update of the other application has failed.

  • Publication number: 20190205877
    Abstract: A digital asset transaction method includes the steps of generating sale and purchase information in a seller and a buyer electronic device, respectively; matching the sale and the purchase information via a transaction server to generate matched information to the seller electronic device; transmitting private key information and the matched information from the seller electronic device to a digital accounting platform for directly transmitting a digital asset from a seller digital asset account to a buyer digital asset account; and, after verifying the transmission of digital asset, the transaction server transferring an amount of transaction currency from a buyer currency account to a seller currency account. Therefore, the digital asset is not transferred via the transaction server but directly transferred from one to another digital asset account once the digital accounting platform receives the private key information and the matched information. Therefore, the risk of digital asset theft is reduced.
