Further, as shown in fig. 2, when a user transacts a service based on derived sub-digital identity information, the user may first operate his client to apply for a Verifiable statement (hereinafter, referred to as "Verifiable credit", for short: VC "), and the client responds to the application operation of the Verifiable statement of the user, sends an application request to a designated mechanism according to the corresponding sub-digital identity information, receives and stores the Verifiable statement returned by the designated mechanism; when a user operates a client side to perform service handling, the client side responds to the service handling operation of the user and sends a service handling request to terminal equipment of a service provider according to a verifiable statement; and the terminal equipment of the service provider verifies the verifiable statement included in the service request based on the sub-digital identity information stored in the blockchain, and performs corresponding service processing based on the verifiable statement when the verification is passed.

the derived password is a character string composed of one or more characters of numbers, letters, special symbols (such as underline) and the like, and the length of the derived password can be set by itself as required in practical application. In order to make the sub-digital identity information derived based on the same root digital identity information different from each other, the derived password and the sub-digital identity information in the embodiments of the present specification have a one-to-one correspondence relationship.

and step S106, sending derived feedback information to the server according to the root number identity information, the derived password and the sub-number identity information, so that the server stores the sub-number identity information into the block chain through the block chain link point when the server passes the verification of the sub-number identity information according to the root number identity information and the derived password.
In one or more embodiments of the present description, a client is capable of deriving, in response to a derivation request by a user, sub-numeric identity information based on root numeric identity information and a corresponding derived password; for the user, the demand that the user uses different digital identity information in different scenes can be met, and the digital identity information can be subjected to derivation management through the client, so that the operation is convenient, and the convenience is improved.
In order to facilitate management of the digital identity information by the user, in one or more embodiments of the present specification, the root digital identity information may be stored in the client in advance, and accordingly, the obtaining of the root digital identity information to be derived in step S102 includes: and acquiring the stored root digital identity information.

Further, the derived password is edited by the user through the client; optionally, when the user needs to derive the sub-digital identity information, the user operates the client to edit a derived password corresponding to the sub-digital identity information to be derived, and submits the derived password to the client. Correspondingly, the acquiring of the derived password in step S102 includes: obtaining a derived password from the derived request;
or, the user can operate his client in advance to edit at least one derived password, and save the derived password in the client; when the user needs to derive the sub-digital identity information, a derived password corresponding to the sub-digital identity information to be derived is selected from derived passwords stored by the client. Correspondingly, the acquiring of the derived password in step S102 includes: presenting the saved at least one undelivered derived password; and acquiring a derivative password selected by the user from the displayed derivative passwords, and taking the derivative password as the derivative password to be derived currently.
Specifically, a first list may be stored in the client, where the first list includes each derived password edited by the user, and a corresponding relationship between a derived password derived from the sub-digital identity information and the sub-digital identity information; correspondingly, the client side responds to the derivation request of the user, obtains the derived password without the corresponding sub-digit identity information from the first list, obtains the derived password without derivation, displays the obtained derived password without derivation, and obtains the derived password selected by the user from the displayed derived password as the derived password to be derived currently. Or, the client may store a second list, where the second list includes each derived password edited by the user, and a corresponding relationship between a derived password and a derived identifier of the derived sub-digit identity information; correspondingly, the client side responds to the derivation request of the user, obtains the derived passwords without corresponding derivation identifications from the second list, obtains the derived passwords without derivation, displays the obtained derived passwords without derivation, and obtains the derived passwords selected by the user from the displayed derived passwords as the derived passwords to be derived currently.

For example, the first preset algorithm is an SHA256 algorithm, and the operation parameters corresponding to the first preset algorithm include 8 initial hash values and 64 constants; since the operation of SHA256 is well known to those skilled in the art, it will not be described in detail here.
It should be noted that the derivation process in the embodiments of the present specification has one-way irreversibility, that is, root digital identity information cannot be inferred reversely according to sub-digital identity information.

The conversion rule and the second preset algorithm can be set automatically according to the requirement in practical application; for example, the root private key and the target character string are both digital character strings, and if the second preset algorithm is an addition algorithm, the root private key and the target character string are added to obtain a second operation result, and the second operation result is used as a sub private key corresponding to the sub-digital identity information.
Step S105-44, deriving a sub public key according to the derived password and the root public key; or, deriving the sub public key according to the sub private key;
wherein deriving the child public key according to the derived password and the root public key comprises:
and according to a third preset algorithm, calculating the root public key, the target character string and the base point on the elliptic curve, and determining the obtained third calculation result as the sub public key corresponding to the sub-digital identity information. Specifically, a fourth operation result is obtained by performing point multiplication operation on the target character string and a G point on the elliptic curve, a third operation result is obtained by performing addition operation on the elliptic curve on the fourth operation result and the root public key, and the third operation result is used as a sub public key corresponding to the sub-digital identity information.

It should be noted that the above-mentioned way of deriving the sub private key and the sub public key according to the derived password, the root private key and the root public key is only a derivation way of deriving the sub private key and the sub public key; the first preset algorithm, the second preset algorithm, the third preset algorithm and the fourth preset algorithm can be set automatically as required in practical application. Therefore, it can be understood by those skilled in the art that any other way of deriving the child private keys and the child public keys based on the derived password, the root private key and the root public key, or based on the derived password, the root private key, the root public key and other additional data, etc. is within the protection scope of this document based on the technical concept of deriving the child private keys and the child public keys provided by the embodiments of the present disclosure.

The foregoing description has been directed to specific embodiments of this disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.
In the 30 s of the 20 th century, improvements in a technology could clearly be distinguished between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Language Description Language), traffic, pl (core unified Programming Language), HDCal, JHDL (Java Hardware Description Language), langue, Lola, HDL, laspam, hardsradware (Hardware Description Language), vhjhd (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
For convenience of description, the above devices are described as being divided into various units by function, and are described separately. Of course, the functions of the units may be implemented in the same software and/or hardware or in multiple software and/or hardware when implementing the embodiments of the present description.

Accordingly, one or more embodiments of the present description may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects. Furthermore, the description may take the form of a computer program product embodied on one or more computer-usable storage media (including, but not limited to, disk storage, CD-ROM, optical storage, and the like) having computer-usable program code embodied therein.
The description has been presented with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the description. It will be understood that each flow and/or block of the flow diagrams and/or block diagrams, and combinations of flows and/or blocks in the flow diagrams and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, embedded processor, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.
These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instruction means which implement the function specified in the flowchart flow or flows and/or block diagram block or blocks.
These computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.
In a typical configuration, a computing device includes one or more processors (CPUs), input/output interfaces, network interfaces, and memory.
The memory may include forms of volatile memory in a computer readable medium, Random Access Memory (RAM) and/or non-volatile memory, such as Read Only Memory (ROM) or flash memory (flash RAM). Memory is an example of a computer-readable medium.
Computer-readable media, including both non-transitory and non-transitory, removable and non-removable media, may implement information storage by any method or technology. The information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), Static Random Access Memory (SRAM), Dynamic Random Access Memory (DRAM), other types of Random Access Memory (RAM), Read Only Memory (ROM), Electrically Erasable Programmable Read Only Memory (EEPROM), flash memory or other memory technology, compact disc read only memory (CD-ROM), Digital Versatile Discs (DVD) or other optical storage, magnetic cassettes, magnetic tape magnetic disk storage or other magnetic storage devices, or any other non-transmission medium that can be used to store information that can be accessed by a computing device. As defined herein, a computer readable medium does not include a transitory computer readable medium such as a modulated data signal and a carrier wave.
It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.
