Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 2, in the embodiment of the present invention, at least a plurality of verification devices, a plurality of user devices and a transaction security chain are disposed in the transaction system,
the user equipment, namely the terminal used by the user, is used for requesting to use the type service according to the user indication.
As shown in fig. 2, the ue is typically connected to an equipment information server, where the equipment information server generates corresponding equipment identity information based on equipment characteristic information (e.g. equipment number, equipment identification code, etc.) of the ue, and returns the equipment identity information to the ue, and the ue stores its own equipment identity information in a local blockchain authentication storage module, and uploads its own equipment identity information to the transaction security chain during non-service occupation (i.e. idle time).
The transaction security chain, which may alternatively be implemented in the form of a cluster of distributed servers, may be shared within the transaction system.
The verification device can perform validity verification on the user device when the user device requests to use the service on site, or can download the device identity information uploaded by the user device from the transaction security chain during non-service occupation (i.e. idle) and perform offline validity verification locally.
As shown in fig. 1, the verification device is generally connected to a service system and a risk control system, the service system notifies the verification device of the transaction rule in advance, the risk control system notifies the verification device of the risk level of each user device for validity verification in advance, and the verification device stores the transaction rule, the risk level and the verification rule in a local blockchain authentication verification module.
The verification device can be realized by a gate, a POS machine, a cashing device, a self-service machine and the like, and the verification device can provide judgment basis for validity verification when the user equipment requests to use a certain service on site.
Based on the system architecture, referring to fig. 3, in the embodiment of the present invention, an outline flow of validity check for the ue based on the blockchain is as follows:
step 300: and the verification equipment downloads the equipment identity information of the user equipment meeting the set conditions from the transaction security chain during the non-business occupation period.
In general, before the verification device downloads the equipment identity information of a user device, it needs to determine whether a corresponding equipment identity information matching identifier exists on the local and transaction security chains, if so, it indicates that other verification devices have performed validity verification on the user device, and if so, the verification device only needs to directly download the corresponding equipment identity information matching identifier, otherwise, the verification device downloads the equipment identity information of the user device from the transaction security chains.
Further, the above setting condition used by the verification device may be preset by a manager, and may be a time range setting condition, for example, device identity information uploaded in three days; the condition can also be set in the geographical position range, for example, the equipment identity information uploaded in the Beijing city range; the service range setting conditions may also be, for example, equipment identity information uploaded by a user equipment capable of accessing the 4G network, or the like, or any combination of the above setting conditions, further, the above limiting conditions are only examples of the setting conditions, and may be flexibly configured according to an application environment in practical application, which is not described herein.
Step 310: and the verification equipment performs validity verification on the obtained equipment identity information of each user equipment, generates corresponding equipment identity information matching identifiers, uploads the obtained equipment identity information matching identifiers to be stored and uploads the equipment identity information matching identifiers to the transaction security chain.
Specifically, the verification device may perform validity verification on the obtained device identity information of each user device according to a service verification rule obtained from the service system and in combination with a risk level of each user device obtained from the risk control system, and when the verification is determined to pass, generate a corresponding device identity information matching identifier, and store the obtained device identity information matching identifier locally, where the device identity information matching identifier is used to characterize a risk level and service content corresponding to the user device; and uploading the equipment identity information matching identifier to a transaction security chain by the verification equipment during non-business occupation.
Among other things, so-called traffic check rules, which may be optional, may be used to configure different service classes, such as: different VIP services, different session services, different levels of personalized services, etc.
In the embodiment of the invention, as each verification device can store the business verification rule and the risk level locally, the verification device can realize offline security verification at any time without connecting with the Internet during non-business occupation, and is quick, efficient and safe.
Meanwhile, after verification, optionally, the verification device can delete the equipment identity information of each user equipment locally and only ensure that the equipment identity information matches the identification, so that the verification device can save the function of locally storing the highest-level security information, and only needs to carry out security cost investment on a server cluster supporting a transaction security chain, thereby greatly reducing the security implementation cost and improving the data security and usability.
Step 320: and the verification equipment downloads the equipment identity information matching identification uploaded by other verification equipment from the transaction security chain and stores the equipment identity information matching identification in a non-business occupation period.
Specifically, all information on the transaction security chain is shared among all the verification devices, and any one verification device can download the device identity information of the required user device at any time and download the device identity information matching identifier required by the downloading.
Step 330: when the verification device receives a service use request sent by a target user device, and when the fact that the device identity information matching identification corresponding to the target user device is stored locally is determined, the target user device is judged to pass through validity verification, and corresponding service is provided based on the device identity information matching identification.
Therefore, the peripheral system cannot acquire the specific content of the transaction safety chain with the equipment identity information only stored, and after the verification equipment sends a request for use, the verification equipment performs validity verification by adopting a black box judgment principle, namely, whether the user equipment can have legal service use permission or not is directly determined according to whether the equipment identity information is matched with the identification, so that the transaction safety of the user equipment is greatly protected, and information leakage is avoided.
Further, in the embodiment of the invention, the verification device needs to periodically re-acquire the device identity information of the user device meeting the set condition from the transaction security chain, perform validity verification on each re-acquired user device to acquire a corresponding device identity information matching identifier, and periodically re-acquire the device identity information matching identifiers newly uploaded by other verification devices from the transaction security chain.
Thus, the real-time performance of the locally stored equipment identity information matching identification can be ensured, and the transaction security of the user equipment is ensured.
Based on the above embodiment, referring to fig. 4, a verification device a and a verification device B are taken as examples, and the above embodiment will be described in further detail.
Step 401: the verification device A acquires the risk level of each user device preconfigured by the risk control system.
Step 402: the verification device A acquires service verification rules of each user device pre-configured by the service system.
Step 403: the equipment information server side generates equipment identity information x by adopting equipment related information of the user equipment x, and sends the equipment identity information x to the user equipment x.
Step 404: the user equipment x stores the equipment identity information x in a local blockchain authentication storage module.
Step 405: the user device x uploads the device identity information x to the transaction security chain at idle.
Step 406: the verification device A downloads the device identity information x from the transaction security chain when idle, and stores the device identity information x in a local blockchain authentication and verification module.
Step 407: and the verification equipment A verifies the equipment identity information x based on the acquired business verification rule and risk level, judges the risk level and business content corresponding to the equipment identity information x, and generates a corresponding equipment identity information matching identifier x.
In the embodiment of the invention, the block chain authentication verification module is additionally arranged in the verification equipment, so that the business verification rule and the risk level can be stored in advance, and the verification of the equipment identity information can be finished locally in an off-line mode.
Here, the conventional device check identifier does not have this function, and since the authentication module is provided in the device, the device can perform operations such as current installation and update through the module.
Step 408: the verification device a informs the user device x that the verification has been passed.
Step 409: and uploading the equipment identity information matching identifier x to a transaction security chain by the verification equipment A when the verification equipment A is idle.
Step 410: and the verification equipment B downloads the equipment identity information matching identifier x in idle time and stores the equipment identity information matching identifier x in a local blockchain authentication and verification module.
In the embodiment of the invention, because the block chain authentication verification module is additionally arranged in the verification equipment, the equipment identity information matching identifier x can be stored in advance, so that a rapid verification function can be provided in subsequent business service.
Step 411: and when the verification equipment B receives the service use request sent by the user equipment X, the user equipment X is verified again through the equipment identity information matching identifier X, and when the verification is confirmed to pass, the corresponding service is provided quickly and safely.
Specifically, the verification device a and the verification device B may be far apart, in the system, as long as the verification device a obtains the device identity information of the user device x from the transaction security chain and completes the validity verification, the verification device B generates and uploads the corresponding device identity information matching identifier x, and the verification device B may share the device identity matching identifier x from the transaction security chain at any time, so that when the user device x approaches the verification device B and requests to use a certain service through the verification device B, the verification device B may rapidly complete the validity verification, and rapidly and safely provide a corresponding service.
Therefore, the user equipment x only needs to complete one-time validity check in the system, the whole system can share the check result without repeated check, so that the check efficiency is effectively shortened, the service speed is improved, and the user experience is further improved.
For example, when a user purchases a year ticket or a multi-venue-cast ticket, the service system synchronizes the service check rule configuration of the year ticket or the service check rule configuration of the multi-venue-cast ticket to the check device a in advance, and when the check device a determines that the year ticket or the multi-venue-cast ticket of the user passes the validity check, the check result is issued to the check terminal of the whole network through the transaction security chain, so that the check device B does not need to perform retrieval check again when the user uses the year ticket to pass the check device B next time. Of course, the service check rule may be configured in various ways, and may be a single rule or a combination rule.
Of course, according to the different service verification rules, the verification device may also perform partial validity verification (e.g., secondary card verification) on the user device according to the service usage request of the user device, which is not described herein.
