Detailed Description
In order to make the technical problems, technical steps and advantageous effects of the present invention more apparent, the present invention will be described in detail with reference to the following embodiments. It should be noted that the specific embodiments described herein are only for illustrating the present invention and are not to be construed as limiting the present invention, and the equivalent substitutions and modifications of the products that can achieve the same functions are included in the scope of the present invention. The specific method comprises the following steps:
example 1: the meta universe currently has no clear, accepted definition as a concept that has just begun to prevail this year. Today the mainstream definition considers the metaspace to be a set of virtual time spaces, which is composed of a series of Augmented Reality (AR), Virtual Reality (VR) and Internet (Internet). Through AR, VR, 5G, artificial intelligence, wearable companion hardware facilities, etc., people can create new universes and civilizations in the meta universe. The meta universe is also known as "internet 3.0" or "post internet era", meaning that the virtual world is about to become the "parallel universe" of the real world. The metastic universe is not an independent world, but a world closely linked and complementary to the real world. In a virtual world with perfect infrastructure, people can realize personal and social requirements such as identity acceptance, currency transaction, professional development and the like in all directions as in a real world. It can be said that the metas is a very general and summarized word. The method not only contains the imagination of human beings to the future scientific and technological society to a certain extent, but also integrates a plurality of popular technologies and industries. This is why, in view of many skilled artisans, the concept of metastables is propagated exponentially, which is necessary in every field.
The recognition and identification of indicia or characteristics of variability among individuals by members of a society in interactive interactions was the first definition of the concept of identity in human society. The self-identity gives the human society relatively stable order and stable structure, is a mark and a name specific to members existing in a group, is used for judging the basic information and the rank status of individuals, and can also be regarded as relationship positioning of inter-individual connection and interaction. The identity of a person in a real society is subject to subjective factors such as age, gender, position, character, preferences, etc., and these determining factors are usually fixed and not modifiable at will. The social identity of a person who exists in a social relationship as a non-independent individual is to a large extent given that social norms, moral awareness, behavioral guidelines must be followed while corresponding duties and obligations are fulfilled. In the real society, the identity becomes the basic standard for determining the status of people, the size of rights and the degree of obligation, and the obtaining of higher identity means obtaining the status and gaining the honor, so the identity becomes the fundamental element for determining the status, the grade and other differences between people, is considered as the concrete embodiment of unfairness and inequality among individuals, and is the most direct and effective tool for maintaining the level and the feeling of separation among individuals.
In the new media era, people build a prosperous and prosperous internet virtual society by taking a network platform as a support. In this very specific society, a wide and huge variety of application services and the vast number of people with different personalities form the fundamental element of the internet, and in this way of communication with digital codes instead of real languages, expressions and emotions, people appear as anonymous, mobile, virtual identities. The premise of participating in network interactive communication is that people need to freely and randomly reconstruct the basic information of themselves and hide the character characteristics of parts, and one or more online virtual identities, namely network ID symbols, which are expected to be displayed and presented to others are freely established by utilizing freely-expanded symbol tools, such as texts, images, videos and the like, so that multiple aspects and multiple levels of self-display can be realized. On the brand-new network platform, people use virtual identities to experience an unprecedented novelty. However, it should be noted that although the construction and use of the network virtual identity presents relative freedom and randomness compared with the real identity, the participation of people in the virtual community process also needs to sequentially follow the corresponding rules and fulfill certain obligations. Therefore, the virtual identity in the network era can be regarded as a behavior which is defined by the virtual world, restricted by the network specification, expected by both interaction parties and suitable for the survival of the network. The generation of virtual identities and the personal management of virtual identities by users are real considerations. Therefore, the present invention has been studied in this direction.
Example 2:
the embodiment analyzes what kind of functions need to be completed by the mobile commerce virtual identity authentication model based on trust transfer, how to establish and manage a virtual identity authentication process with different safety, and simplifies identity authentication calculation and operation under the environment that multiple parties participate in mobile commerce. A virtual identity authentication model based on trust delivery. Although the final access control authority is ultimately decided and enforced by a party (typically the party providing and controlling the resource), such decision authority depends more on information provided by other parties in establishing a trust relationship and the formulated contract and its security information.
The model is characterized by being seamlessly integrated into existing identity authentication systems or frameworks without having to rebuild the associated authentication infrastructure. This means that the model must be adaptable to the currently prevailing authentication mechanisms. In addition, the topology, relationship and mechanism of the model must have high adaptability, and can adapt to the existing identity authentication system and its resources without changing.
The model can realize the following functions:
(1) identity authentication participants between security domains of different structures or modes are allowed to share identity information, authentication information, rights information, and other related data.
(2) Different security tokens, authentication modes and security frameworks are allowed to be used by security domains in which different identity authentication participants are located.
(3) The delivery of trust relationships and the exchange of critical information operate based on internet protocols and internet environments, particularly mobile internet environments.
(4) The virtual identity authentication process is bidirectional, and can provide services for the user side and the resource providing side.
(5) The trust relationship and the authentication information should be maintained, and when the information changes, the virtual identity authentication should be reestablished, so that potential safety hazards are avoided.
(6) Identity information and security models should be hierarchical to avoid unnecessary, excessive, and illegal trust and identity authentication processes.
(7) Anonymous identity authentication is not allowed.
The virtual identity authentication scheme may have the following several:
(1) virtual identity authentication scheme based on dynamic password
A virtual identity authentication scheme based on a dynamic password is realized by combining a virtual identity authentication flow with W on the basis of the dynamic password, so that on one hand, the computing strength of a server and a client can be reduced, and the denial of service attack can be resisted; and on the other hand, phishing attacks can be prevented by means of bidirectional authentication. The scheme simplifies the flow of user authentication and authorization on the premise of ensuring the safety and effectively improves the authentication efficiency.
(2) Virtual identity authentication scheme based on digital signature
A false and smart identity authentication scheme based on digital signatures adopts an asymmetric encryption technology, and utilizes a digital certificate and the digital signatures to ensure non-repudiation of transactions, thereby solving one of the biggest problems of virtual identity authentication compared with the identity authentication scheme involving multiple traditional parties: and (5) identity confirmation. The scheme needs the support of the client, namely, a U shield is used or a digital certificate plug-in is installed at the client.
(3) Virtual identity authentication scheme based on trusted H-th party
On one hand, the computing intensity of both the server side and the client side can be reduced, and the denial of service attack can be resisted; and on the other hand, phishing attacks can be prevented by means of bidirectional authentication. The scheme simplifies the flow of user authentication and authorization on the premise of ensuring the safety and effectively improves the authentication efficiency.

the direction of identity conversion is used for explaining the direction of rotation of the simulation identity pile during identity conversion; step eight, after the user generates the virtual identities, the number of the virtual identities simultaneously owned by the user is M, the identity recording file comprises an identity recording head, a reserved space, an active space, more than one virtual identity entry and an identity description table, the identity recording head is arranged at the beginning of the identity recording file, the identity recording head comprises a file identification code, information of a virtual identity card, an identity description pointer and a storage mode, and the identity recording head is used for describing basic information of the identity recording file; the file identification code is used for identifying the identity recording file and is 8 hexadecimal numbers, as long as the file identification code in the identity recording head is read, an administrator confirms the file as the identity recording file, the information of the virtual identity card is the public key address of the virtual identity card, the identity description needle stores the address of the identity description table starting in the identity recording file, and the identity description needle is used for describing the position of the identity description table; the head address of the identity recording file is 0, the storage mode is a minimum data unit stored in the identity recording file, and whether the data storage is a small-end mode or a large-end mode, the minimum data unit stored in the identity recording file is used for explaining a minimum separation unit of data when the data in the identity recording file is stored, and the data space occupied by an identity recording head, a reserved space, an active space, more than one virtual identity entry and an identity description table is necessarily multiple of the minimum data unit stored in the identity recording file; m is a natural number, and the value of M is set by an administrator; the reserved space is a reserved storage space of the identity recording file, the active space is used for explaining the record of using the virtual identity by the user, the starting address of the active space is designated by the user, and the active space is stored in a descending manner from a high address to a low address; step nine, the record of the virtual identity used by the user comprises an index code of the virtual identity and a time interval of the virtual identity, the time intervals of the default virtual identity are not intersected, the value of the minimum data unit stored in the identity description needle minus the identity record file is used as the starting address of the virtual identity entry, the virtual identity entry is stored in a descending manner from the high address to the low address, the virtual identity entry comprises the index code of the virtual identity of the user, the nickname, the role and the effective period of the virtual identity, and the virtual identity entry is used for describing the information of each virtual identity of the user; the index code, the starting address and the occupied space of each virtual identity entry are described in an identity description table, and the identity description table is used for managing the information of the virtual identity entries of the user in the identity record file; the user selects to use the virtual identity, and then the virtual identity is mapped to the virtual identity item through the identity description table, and the information of using the virtual identity is recorded in the activity space.
