Problems solved by technology

In a networked environment, the user's account private key data is completely handed over to the software program for encrypted storage and processing. If the developer of the wallet does evil, the risk of the user's account private key being leaked is extremely high
[0008] 2. Vulnerable to hacking
[0011] 2. Low cost performance: Common cheap data storage items (such as U disk, sticky notes) can only be used for account backup, and cannot participate in actual transactions; and full-featured cold wallet products are often expensive, such as library God (4288 yuan), ImToken offline use (requires a smartphone with permanent flight mode as a carrier)
[0012] 3. The physical carrier is easy to lose and damage: as an independent physical carrier, due to the characteristics of not being connected to the Internet and the low frequency of use, it is easy to be forgotten and lost by users; if some cheap storage items are used, the carrier itself will also be damaged. High risk of damage and malfunction

Embodiment 1

[0049] The digital pass backup method in this embodiment refers to uploading the locally stored digital pass to the server for storage.

[0050] This embodiment provides a method for backing up a digital certificate, the method is applied to a card, and the card is set in a terminal; as figure 1 As shown, the method includes.

[0051] Step 11, the card obtains a digital pass backup request, the card stores at least one digital pass, and the digital pass backup request is that the application server receives the digital pass sent by the terminal through the application client. The application client is installed on the terminal, the digital certificate backup instruction includes a digital certificate identifier, and the digital certificate backup request includes the digital certificate identifier.

[0052] The card obtains a digital certificate backup request from the terminal. The terminal may be an intelligent terminal such as a mobile phone. The user can initiate a digi...

Embodiment 2

[0083] This embodiment provides a digital certificate recovery method, the method is applied to a card, and the card is set in the terminal; as figure 2 As shown, the method includes.

[0084] Step 21: The card uses the terminal to send registration information to the application server, the registration information is information encrypted by the card according to preset encryption rules, so that the application server can verify whether the card is a legitimate card, The registration information includes an integrated circuit card identification code (Integrate circuit card identity, ICCID) of the card.

[0085] Step 22, the card obtains the user's digital pass recovery information, the digital pass recovery information includes the user's digital pass, and the digital pass recovery information is that the application server verifies that the card is a legal card Information sent later to the terminal; wherein, when the preset encryption rule matches the decryption rule of...

Embodiment 3

[0109] This embodiment provides a digital pass backup card, the card is used to be set in the terminal; as image 3 As shown, the card includes: an acquisition module 31, a processing module 32;

[0110] The acquiring module 31 is used to acquire a digital pass backup request, the card stores at least one digital pass, and the digital pass backup request is that the application server receives the digital pass sent by the terminal through the application client. The information sent after the pass backup instruction, the application client is installed on the terminal, the digital pass backup instruction includes the digital pass identification, and the digital pass backup request includes the digital pass identification;

[0111] The processing module 32 uses the terminal to send the digital certificate corresponding to the digital certificate identifier to the application server according to the digital certificate backup request, so as to back up the digital certificate cor...

Abstract

The invention discloses a digital pass backup method and recovery method. The backup method is applied to a card, and the card is set in a terminal; including: the card obtains a digital pass backup request, and the card stores at least one digital certificate, the digital certificate backup request is information sent by the application server after receiving the digital certificate backup instruction sent by the terminal through the application client, the application client is installed on the terminal, The digital certificate backup instruction includes a digital certificate identifier, and the digital certificate backup request includes the digital certificate identifier; the card uses the terminal to send the digital certificate to the application server according to the digital certificate backup request. The digital certificate corresponding to the digital certificate identifier is used to back up the digital certificate corresponding to the digital certificate identifier to the application server. The scheme of the present invention improves the security and convenience for users to back up and restore digital certificates.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a method for backing up and restoring digital certificates. Background technique [0002] In recent years, blockchain technology has been recognized by the industry as the foundational technology for the future value Internet. With the enthusiasm of a large number of technology enthusiasts and investors, the market value of encrypted digital currency has been rising steadily, accompanied by various digital wallet products for managing digital currency accounts. [0003] The current digital currency wallet products can be divided into hot wallets (online wallets) and cold wallets (offline wallets) according to whether they are connected to the Internet. [0004] Hot wallet: A product that encrypts and stores sensitive data such as blockchain account private keys by devices connected to the Internet. Representative products include ImToken, MEW, Jaxx, exchange account custod...
