Fig. 1 is a schematic view of an application scenario of an alarm method according to one or more embodiments of the present disclosure, and as shown in fig. 1, the system includes: the system comprises a plurality of alarm terminals and a plurality of alarm receiving terminals, wherein the alarm terminals can be merchant servers providing business services, such as a server providing taxi taking services, a server providing ordering services and the like, and the alarm receiving terminals can be background servers of public inspection institutions, and the specific process of alarming is as follows:

(1) the method comprises the steps that an alarm terminal receives an alarm request sent by a user terminal, wherein when the user is in danger, the user terminal generates the alarm request based on touch operation of a user on an alarm trigger control on a display interface, and the user terminal sends the alarm request to the alarm terminal, wherein the alarm request can carry an order identification;

(2) after receiving an alarm request, an alarm terminal determines plaintext data of a service order corresponding to the alarm request, wherein the plaintext data can be obtained by decrypting ciphertext data uploaded to a block chain in advance by the alarm terminal or obtained by inquiring the plaintext data of the service order corresponding to the alarm request in a local database, in the example of fig. 1, ciphertext data uploaded to the block chain is directly decrypted to obtain plaintext data, and the alarm terminal directly decrypts the ciphertext data uploaded to the block chain in advance corresponding to the alarm request to obtain plaintext data;

(3) the alarm terminal stores the determined plaintext data of the service order corresponding to the alarm request to the block chain, wherein the plaintext data is stored to the block chain after decryption is completed aiming at the condition that the alarm terminal decrypts the plaintext data obtained by decrypting the ciphertext data uploaded to the block chain in advance, and in addition, a plurality of alarm receiving terminals are also accessed to the block chain, and each alarm receiving terminal is used as a node in the block chain;

(4) the alarm receiving terminal monitors order data of a service order stored in a block chain in real time, wherein the order data is data stored in the block chain by the alarm terminal, the order data can be ciphertext data of the service order linked by the alarm terminal, or plaintext data of the service order corresponding to the alarm request and stored in the block chain when the alarm request is received, and the order data stored in the block chain can be checked in real time for the alarm receiving terminal as the alarm terminal and the alarm receiving terminal are both connected into the same block chain;

(5) if the alarm receiving terminal monitors that plaintext data of a service order is stored in the block chain, determining the service order of the plaintext data as the service order corresponding to the alarm request, wherein the plaintext data of the service order is required to be processed by the alarm receiving terminal, and ciphertext data of the service order cannot be identified for the alarm receiving terminal, so that the monitored plaintext data of the service order is obtained;

(6) the alarm receiving terminal responds to the alarm request of the user terminal based on the acquired plaintext data of the service order corresponding to the alarm request, specifically, the alarm receiving terminal can judge whether the corresponding alarm request belongs to the alarm output range of the alarm receiving terminal according to the plaintext data of the service order corresponding to the acquired alarm request, if so, corresponding alarm information is generated, the alarm information is displayed or an alarm is sent out based on the alarm information, so that an alarm output action is executed by an alarm party at the first time, the alarm efficiency is improved, and the safety of the user is improved.

Fig. 2 is a first flowchart of an alarm method provided in one or more embodiments of the present specification, where the method in fig. 2 can be executed by an alarm terminal of an access block chain in fig. 1, and as shown in fig. 2, the method at least includes the following steps:

s201, receiving an alarm request sent by a user terminal, wherein for the online taxi taking service, the user terminal can be a taxi renting terminal or an owner terminal; for the on-line ordering service, the user terminal can be a meal ordering terminal or a meal delivery terminal; for the online shopping service, the user terminal may be a buyer terminal or a seller terminal;

specifically, when a user using a user terminal is in danger, the user may touch an alarm trigger control on a display interface of the user terminal by one key, and at this time, after the user terminal detects a touch operation of the user, an alarm request is generated based on the touch operation, and the user terminal sends the alarm request to an alarm terminal (i.e., a merchant server providing a business service), where the alarm request may carry an order identifier of a business order that needs to request an alarm.

S202, determining the plaintext data of the service order corresponding to the received alarm request, specifically, after the alarm terminal receives the alarm request, the ciphertext data of the service order corresponding to the alarm request, which is uploaded to the block chain in advance, can be directly decrypted to obtain plaintext data, the plaintext data of the service order corresponding to the alarm request can be inquired in a local database, wherein, the alarm terminal can adopt either the mode of the lower single uplink or the alarm uplink to upload the service order data to the block chain, preferably, the mode of the lower single uplink, the generated business order data are all hashed and uploaded to the block chain, so that the traceability of the business order data can be ensured, any business order data are required to be used subsequently, decrypting the ciphertext data of the corresponding service order in the block chain to obtain plaintext data;

s203, storing the plaintext data of the service order corresponding to the determined alarm request to a block chain, so that an alarm receiving terminal accessed to the block chain responds to the alarm request of the user terminal based on the plaintext data;

specifically, for the situation that ciphertext data linked in advance is decrypted to obtain plaintext data, the alarm terminal directly decrypts the ciphertext data on the block chain, namely, the ciphertext data is automatically stored in the block chain, and for the situation that the plaintext data is searched in a local database, the alarm terminal needs to upload the searched plaintext data to the block chain;

wherein, because to a plurality of nodes of accessing same block chain, no matter which node uploads the target data to the block chain, each node of accessing this block chain all can acquire this target data, consequently, need all access alarm terminal and receive alarm terminal in the block chain in advance, specifically do:

the alarm terminal receives a block link access request; and responding to the block link access request to access the block chain, so that the alarm terminal becomes a node in the block chain;

and the alarm receiving terminal also receives the block link entering request; and accessing the blockchain in response to the blockchain access request, so that the alarm receiving terminal also becomes a node in the blockchain;

after the alarm terminal stores the plaintext data of the service order corresponding to the alarm request to the blockchain, the alarm receiving terminal accessing the blockchain can automatically acquire the plaintext data of the service order corresponding to the alarm request, and then the alarm receiving terminal can judge whether the corresponding alarm request belongs to the alarm output range of the alarm receiving terminal according to the acquired plaintext data of the service order corresponding to the alarm request, if so, corresponding alarm information is generated, the alarm information is displayed or an alarm is sent out based on the alarm information, so that an alarm output action can be executed by an alarm party at the first time.

In one or more embodiments of the present disclosure, both the alarm terminal and the alarm receiving terminal are accessed into the block chain, and the alarm terminal stores plaintext data of a service order corresponding to an alarm request to the block chain at the first time, so that the alarm receiving terminal accessed into the block chain at the same time can be ensured to view the plaintext data in time, and the alarm request of a user is transmitted to the alarm receiving terminal in real time, so that an police can give an alarm in time based on the plaintext data of the service order corresponding to the alarm request acquired by the alarm receiving terminal, thereby improving alarm efficiency and improving safety of the user.

Further, considering that a plurality of nodes may be connected to the same block chain, where a competition relationship may exist between two nodes, in order to ensure confidentiality of normal business order data of a merchant, and because an alarm receiving terminal cannot identify ciphertext data, in order to facilitate the alarm receiving terminal to quickly identify data of a business order corresponding to an alarm request, plaintext data of a business order may be encrypted and then uploaded, and once a certain business order becomes a business order corresponding to an alarm request, ciphertext data corresponding to the business order may be decrypted to obtain corresponding plaintext data, as shown in fig. 3, before S201 receives an alarm request sent by a user terminal, the method further includes:

s204, encrypting plaintext data of the business order to obtain ciphertext data of the business order, wherein the plaintext data of the business order is generated based on business services provided by a merchant platform for a user, and a unique order identifier is distributed to each business order when the business order is generated;

specifically, when the alarm terminal determines that the service order data meets the chaining condition, the alarm terminal encrypts the service data, can encrypt the plaintext data of the service order by using a public key, and then decrypts the ciphertext data of the service order by using a private key corresponding to the public key if the plaintext data of the service order needs to be used, so as to obtain the plaintext data of the service order;

and S205, uploading the encrypted ciphertext data of the service order to the block chain, wherein in consideration of the fact that the data stored in the block chain is not falsifiable and traceable, the alarm terminal can adopt a form of ordering and uploading, that is, the service order data is encrypted and uploaded to the block chain, so that any service order can be traced in the subsequent process.

In one or more embodiments of the present disclosure, in order to a situation that a merchant uses a mode of placing orders and uploading business order data to a block chain, plaintext data of a business order may be encrypted, and then ciphertext data of the encrypted business order may be uploaded to the block chain, and after an alarm request of a user terminal is received, ciphertext data of the business order corresponding to the alarm request in the block chain may be decrypted to obtain plaintext data, so that not only can confidentiality of a normal business order be ensured, but also data of the business order corresponding to the alarm request may be quickly identified by an alarm receiving terminal.

Further, considering that there may be a case where the plaintext data of the service order includes at least one item of attribute data related to time, for example, for a service order generated by an online taxi taking service, correspondingly, the plaintext data of the service order includes a driving track, and the driving track is refined over time, and the driving track is a driving route from a starting position to a destination when the order is completed, so that the driving track in the service order data needs to be updated in real time, based on this, as shown in fig. 4, the above S204 performs an encryption process on the plaintext data of the service order to obtain ciphertext data of the service order, specifically including:

s2041, determining a target preset condition corresponding to the business order according to the type of the business order, wherein the preset condition comprises: generating a business order for the first time, wherein the order execution time reaches at least one of a preset threshold value and business order completion; specifically, the corresponding relationship between the type of the service order and the target preset condition can be set;

s2042, judging whether the current order execution state of the business order meets a target preset condition corresponding to the business order;

specifically, the target preset condition corresponding to the service order may be determined according to the type of the service order, and then it is determined whether the current order execution state of the service order meets the target preset condition, for example, in case that the plaintext data of the service order includes at least one item of attribute data related to time, the target preset condition of the service order includes: the method includes the steps that a service order is generated for the first time, order execution time reaches a preset threshold value, and the service order is completed, namely when the current order execution state of the service order meets the condition that the order execution time reaches the preset threshold value, namely when service order data are sent and changed, encrypted ciphertext data of the service order also need to be uploaded to a block chain;

if the judgment result is yes, executing S2043, and encrypting the plaintext data of the service order to obtain ciphertext data of the service order;

specifically, for the case that the plaintext data of the service order includes at least one item of attribute data related to time, it is necessary to not only upload the service order data generated for the first time to the block chain, but also continuously update the attribute data related to time in the service order data;

if not, determining whether the service order is completed and chaining the ciphertext data of the service order, and if not, continuing to execute step S2042.

Specifically, the process of determining plaintext data of a service order corresponding to an alarm request by an alarm terminal may be implemented by directly decrypting ciphertext data of the service order corresponding to the alarm request, which is uploaded to a block chain in advance, or by querying plaintext data of the service order corresponding to the alarm request in a local database, and specifically, the process of determining plaintext data of the service order corresponding to the alarm request by the alarm terminal is implemented by directly decrypting ciphertext data of the service order corresponding to the alarm request, which is uploaded to the block chain in advance, to obtain plaintext data specifically:

as shown in fig. 5a, the determining, in S202, plaintext data of a service order corresponding to the received alarm request specifically includes:

s2021, searching ciphertext data of a service order corresponding to the received alarm request in a block chain accessed by the alarm terminal;

the alarm terminal uploads encrypted ciphertext data of a service order to a block chain when generating the service order, and when a user terminal initiates an alarm request for a certain service order, the ciphertext data of the service order corresponding to the received alarm request is automatically searched;

s2022, carrying out decryption processing on the ciphertext data of the service order corresponding to the searched alarm request to obtain plaintext data of the service order corresponding to the alarm request; specifically, after ciphertext data of the service order corresponding to the alarm request is found, the ciphertext data is decrypted by using a private key, and corresponding plaintext data can be obtained.

Specifically, for the case of querying plaintext data of a service order corresponding to the alarm request in the local database, the method specifically includes:

as shown in fig. 5b, the determining, in S202, plaintext data of a service order corresponding to the received alarm request specifically includes:

s2023, determining an order identifier of the business order carried in the received alarm request;

s2024, searching plaintext data corresponding to the determined order identification of the business order in a local database; specifically, the found plaintext data is determined as the plaintext data of the service order corresponding to the received alarm request, and the corresponding plaintext data can be directly inquired and uploaded to the block chain in response to the situation that the plaintext data of the service order corresponding to the alarm request is locally stored in the alarm terminal.

In one or more embodiments of the present disclosure, in consideration that data stored in a block chain has encryption and non-tamper-resistance, it is preferable to directly decrypt ciphertext data of a service order corresponding to an alarm request, which is uploaded to the block chain in advance, to obtain plaintext data, so that accuracy of the plaintext data transmitted to an alarm receiving terminal can be ensured.

The plaintext data for the service order comprises: in the case of at least one item of time-related attribute data, for example, a service order generated for an online taxi-taking service, the clear text data of the service order includes a driving track, and the driving track is continuously improved over time, and when the order is completed, the driving track is a driving route from a starting position to a destination, so that the driving track in the service order data needs to be updated in real time;

in the process of encrypting the plaintext data of the service order, when the current order execution state of the service order meets the condition that the order execution time reaches a preset threshold value, the plaintext data of the service order is encrypted, so that the encrypted ciphertext data of the service order also needs to be uploaded to a block chain when the service order data is sent and changed;

correspondingly, the uploading, by the S205, the encrypted ciphertext data of the service order to the block chain specifically includes:

and uploading the latest ciphertext data aiming at the same business order to a block chain according to a preset time interval.

Correspondingly, when a service order is in the process of executing, if an alarm request of a user terminal for the service order is received, plaintext data of the service order corresponding to the received alarm request needs to be determined according to a preset time interval, that is, as long as ciphertext data of the service order corresponding to the alarm request exists on a block chain, the ciphertext data needs to be decrypted to obtain plaintext data;

correspondingly, the step S203 of storing the plaintext data of the service order corresponding to the determined alarm request to the block chain specifically includes:

and storing the latest plaintext data of the service order corresponding to the determined alarm request to the block chain according to a preset time interval.

Furthermore, considering that plaintext data of all service orders on the block chain is visible for the alarm receiving terminal, the alarm receiving terminal needs to select alarm information belonging to the management of the alarm receiving terminal, so that in order to reduce the need for the alarm receiving terminal to exclude too many alarm information not belonging to the jurisdiction range of the alarm receiving terminal, based on this, if the service area in charge of the alarm receiving terminal accessing the block chain is a first service area, the service area in charge of the alarm terminal accessing the block chain is a second service area;

correspondingly, the first service area and the second service area satisfy a preset position relationship, preferably, the first service area is the same as the second service area, for example, if the area where the business service provided by the merchant server accessing the block chain is facing to the user is in beijing, the background server of the public inspection agency in beijing is accessed into the block chain at the same time.

In a specific embodiment, taking a service order corresponding to an alarm request of a user terminal as an example of a service order generated by an online taxi taking service, a process of triggering a public security organization to acquire alarm information for the alarm request is specifically as follows:

as shown in fig. 6, the alarm terminal accessing the block chain includes: the system comprises a merchant terminal 1 providing online shopping service, a merchant terminal 2 providing online ordering service, a merchant terminal 3 providing online taxi taking service and the like, wherein the alarm receiving terminal accessing the block chain comprises: a public security terminal;

(1) the process for order data chaining specifically comprises the following steps:

after each merchant terminal generates a business order, encrypting plaintext data of the business order to obtain ciphertext data of the business order, and uploading the ciphertext data of the business order to a block chain;

the plaintext data of the business order generated by the merchant terminal 2 may include: distributor identity information, user identity information, order receiving time, delivery address, distributor current geographical location information, user current geographical location information, and the like; the clear data of the business order generated by the merchant terminal 3 may include: driver identity information, user identity information, vehicle registration information, order taking time, destination, current vehicle geographic position information and vehicle running track information;

in addition, for the merchant terminal 3, the current geographic position information of the vehicle and the vehicle driving track information are changed with time, so that the latest ciphertext data for the same service order needs to be uploaded to the block chain at preset time intervals.

(2) The process for determining plaintext data for a service order specifically includes:

after receiving an alarm request sent by a user terminal, a merchant terminal 3 determines a hash value of a business order corresponding to the alarm request, and searches ciphertext data of the business order corresponding to the alarm request in a block chain based on the hash value;

and decrypting the ciphertext data of the service order corresponding to the found alarm request to obtain the plaintext data of the service order corresponding to the alarm request.

(3) The process of acquiring plaintext data for a public security terminal specifically comprises the following steps:

the method comprises the steps that a public security terminal monitors order data of a service order stored in a block chain in real time, and if plaintext data of the service order is stored in the monitored block chain, the service order of the plaintext data is determined to be the service order corresponding to an alarm request, wherein the plaintext data stored in the block chain is required to be processed by the public security terminal, and ciphertext data of the service order cannot be identified for the public security terminal, so that the monitored plaintext data of the service order is reserved;

the public security terminal responds to the alarm request of the user terminal based on the plaintext data of the service order corresponding to the obtained alarm request, specifically, the public security terminal can judge whether the corresponding alarm request belongs to the alarm output range of the public security terminal according to the plaintext data of the service order corresponding to the obtained alarm request, if yes, corresponding alarm information is generated, the alarm information is displayed or an alarm is sent out based on the alarm information, so that an alarm output action is executed by an alarm party at the first time, the alarm efficiency is improved, and the safety of the user is improved.

In one or more embodiments of the present disclosure, both the alarm terminal and the alarm receiving terminal are accessed into the block chain, and the alarm terminal stores plaintext data of a service order corresponding to an alarm request to the block chain at the first time, so that the alarm receiving terminal accessed into the block chain at the same time can be ensured to view the plaintext data in time, and the alarm request of a user is transmitted to the alarm receiving terminal in real time, so that an police can give an alarm in time based on the plaintext data of the service order corresponding to the alarm request acquired by the alarm receiving terminal, thereby improving alarm efficiency and improving safety of the user.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish 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), Cal, jhdware Description Language, langua, mylar, pams, Hardware (Hardware Description Language), langva, Lola, HDL, palmware, Hardware (Hardware Description Language), VHDL (Hardware Description Language), and the like, which are currently used in the most popular languages. 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.
