Description

E-wallet generation and restoration method

The invention relates to a method for generating and restoring an electronic wallet, in particular, a method for verifying that a subsequent step of recording a specific information through a user's handwriting, and starting a subsequent verification or transmission process.

In the late 1960s, due to various fields of attack and defense between the United States and the Soviet Union, the Internet appeared and began to protect national security.

Today, the Internet as a network of people can connect to the Internet through electronic products, for advertising, trading virtual or actual products, operating financial resources, news media, education and learning, contacts and people A tool for feelings.

And more and more people using the Internet have awareness and ideas to protect personal networks, privacy and property information, while privacy on personal electronic products is also being watched by many users or developers. Protecting your own personal rights/rights, or the rights/rights of members in a particular group, generally begins with the use of private accounts, private passwords, private electronic products, and so on.

Corresponding to the above-mentioned various needs to be secured on the Internet, the state, government, media, online stores, etc. continue to research and develop and use digital systems or hardware equipment that can protect consumers or log in member information.

Accordingly, how to digitally protect the consumer or log in to the member's data system or hardware equipment to verify whether the online operator is the holder himself or not will be regarded as a major issue.

The main object of the present invention is to establish a private operation inside a stored product that can determine the key for trading digital asset data, and transmit the completed key data to the electronic product that can be connected to the network. The user can connect the stored product to the electronic product while the electronic product is connected to the network, and operate the key data in the electronic product to conduct the transaction of the personal digital asset on the network line.

A secondary object of the present invention is that the user must prepare a record to store the specific information displayed by the product (Mnemonic) before transmitting the key data to the electronic product that can be connected to the network, as the verification of the current storage product. The method of being the same person as the person holding the electronic product, and the process of verification does not pass through the electronic product, and the situation in which the person who holds the stored product is not the same as the person who holds the electronic product is avoided.

Yet another object of the present invention is to allow a user to lose or damage one of the electronic products and storage products that can be connected to the network, through the old electronic products and the new storage products, or the new electronic products and the old ones. The storage product, or the new electronic product and the new storage product are re-connected to each other, and the user can use the specific information held by the individual (Mnemonic) to restore the personal product within the electronic product and/or the stored product. The job of the key.

To achieve the above object, the method for generating an electronic wallet of the present invention can be connected to a network device through a closed storage device, wherein the storage device stores a key capable of confirming the step of performing a digital asset transaction, and the storage device includes An information communication unit, an operation interface, a processor, and a security chip, wherein the method includes: the network connection device generates a request for establishing an electronic wallet, and the establishment request is transmitted to the security chip via the processor, where the security chip is based on After the establishing request performs internal state detection and confirms that the internal state is a state without an electronic wallet, an electronic wallet is established in the security chip; the processor requests the security chip to generate a restoration code, and the above information is transmitted through the information transmission unit. The restoration code is provided to a user to record a backup; the network connection device obtains an encrypted asset information located in the electronic wallet, and interprets the encrypted asset information to establish a public electronic wallet information.

The restoration code is presented on the surface of the storage device through the information transmission unit, and the user receives and records the backup restoration code by a sensory perception such as touch, listening, and visual observation.

Moreover, after the operation interface obtains an instruction to complete the record input by the user, the storage device confirms that the user has completed the backup of the restoration code record.

A method for restoring an electronic wallet, in a first preferred embodiment, the user can be connected to a network device through a storage device, and the storage device stores a key capable of determining a step of performing a digital asset transaction, and the storing The device includes an information communication unit, an operation interface, a processor, and a security chip.
