Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment of the invention discloses a password verification method of shared equipment, the shared equipment, a cloud server and a system, so that the password synchronization verification process between a user and the shared equipment can be realized under the condition that the shared equipment and the cloud server are not required to be connected with a network.

Referring to fig. 1, an embodiment of the present invention discloses a flowchart of a password verification method for a sharing device, where the method is applied to a cloud server, the cloud server corresponds to at least one sharing device, the cloud server has a plurality of cloud password libraries, and each cloud password library corresponds to one sharing device, and the method includes:

s101, acquiring an equipment identity of shared equipment to be used, which is input by a user, and determining a corresponding cloud password library according to the equipment identity;

in practical application, a user may scan the two-dimensional code of the shared device through a mobile phone, an IPAD, and other terminals to obtain the device identity of the shared device, where the device identity is also a device identifier. Of course, the user may also obtain the device identity of the sharing device in other manners, such as by inputting the identity code printed on the sharing device into a computer to obtain the device identity of the sharing device.

Wherein each sharing device has a device identity uniquely corresponding thereto.

Step S102, user information input by a user and requirement information of shared equipment to be used are obtained;

specifically, the user information specifically refers to identity information of the user, such as an identification number.

For the requirement information of the shared device, for example, assuming that the shared device is a shared washing machine, the requirement information of the user on the shared washing machine includes: duration of washing, number of rinses, washing temperature, speed of rotation, etc.

Step S103, selecting a cloud password group from the cloud password library, and recording the cloud password group and the user information in a corresponding relationship form;

in this embodiment, one cloud password library includes a plurality of cloud password groups, each cloud password group corresponds to one user, and each cloud password group is a set of all passwords generated by the sharing device under different working conditions according to a preset password generation rule, that is, each cloud password group includes all conditions of the sharing device required by the user. For example, assuming that the shared device is a shared washing machine, the information of the user's requirement for the shared washing machine, i.e. the working condition of the shared washing machine, is as follows: the washing time is 30 minutes, and the washing mode is as follows: and (4) rinsing twice and dehydrating once, wherein the clothes type is shirt, and a password uniquely corresponding to the demand information is obtained according to the demand information and a preset password generation rule such as a password generation formula.

The shared washing machine generates a set of all passwords according to the permutation and combination of the preset password generation rules under different working conditions, and a cloud password group is obtained.

When the cloud password groups are sequentially arranged in the cloud password library, the cloud password group arranged at the forefront can be used as the selected cloud password group, and certainly, one cloud password group can be randomly selected.

The purpose of recording the cloud password group and the user information in the form of the corresponding relationship is as follows: the real-name system used by the sharing equipment is realized, so that services are prevented from being provided for users who do not meet the age requirement, for example, users who use the sharing bicycle need to be aged up to 12 years old, and conditions are provided for the follow-up purchase of personal accident injury risks and third party liability risks for the users.

In practical application, different levels can be set for each cloud password group contained in the cloud password library, and meanwhile, different levels are set for users, for example, the level of a user is determined according to the total times of using the sharing device by the user all the time, the more times the user uses, the higher the level of the user is, and the user at the same level corresponds to the cloud password group.

Therefore, the execution process of this step is specifically: the method comprises the steps of firstly determining a plurality of cloud password groups corresponding to shared equipment to be used, secondly determining a user level according to user information, and determining the corresponding cloud password groups according to the user level.

Step S104, extracting a password corresponding to the demand information from the cloud password group;

the password is obtained by adopting a preset password generation rule on the demand information in advance, namely the password is generated under different arrangement combinations of working conditions of the sharing equipment according to the preset password generation rule, so that the corresponding password can be extracted from the cloud password group according to the demand information, namely the working conditions of the sharing equipment.

And step S105, feeding the password back to the user so that the user can determine the requirement information of the user by using the password and the own device side password library by the to-be-used sharing device when using the to-be-used sharing device, and completing the synchronous verification of the password.

Specifically, the cloud password library feeds the searched password back to the user, when the user uses the to-be-used sharing device, the user inputs the password into the to-be-used sharing device, the to-be-used sharing device searches whether the password identical to the password input by the user is stored in the device side password library of the to-be-used sharing device or not by using the password, if yes, the searched password and the preset password generation rule are used for determining the requirement information of the user, and synchronous verification of the password is completed.

The device side password library comprises a plurality of device side password groups, each device side password group corresponds to one user, all passwords stored in the device side password library by each sharing device and passwords in the cloud password library corresponding to the sharing device are generated by the same preset password generation rule for the requirement information of the users, and therefore the sharing device can determine the requirement information of the users according to the passwords acquired by the users from the cloud password library.

To sum up, the password verification method for the sharing device disclosed by the invention adopts the same preset password generation rule for the password in the cloud password library corresponding to the sharing device in the cloud server and the password in the device side password library of the sharing device, so that a user can firstly extract the corresponding password from the cloud password library by using the demand information of the device to be used before using the sharing device, the password is obtained by adopting the preset password generation rule for the demand information in advance, then the password is input into the sharing device, and when the sharing device finds the password corresponding to the password from the device side password library of the sharing device, the found password and the preset password generation rule can be used for determining the demand information of the user, thereby completing the synchronous verification of the password. Therefore, the invention realizes the synchronous password verification process between the user and the sharing equipment based on the same password generation rule under the condition that the cloud server and the sharing equipment are not connected with the network, thereby ensuring that the use of the sharing equipment is not limited by the network any more and further effectively avoiding the risk of unsafe attack of the internet.

In addition, because the method disclosed by the invention does not need to establish network connection between the sharing equipment and the cloud server, compared with the traditional scheme, the method disclosed by the invention also saves a wireless module arranged on the sharing equipment, thereby saving the hardware cost of the sharing equipment.

It can be understood that different sharing devices may have different requirements for the payment time, such as a shared washing machine, and when the user determines the demand information for the shared washing machine, the shared washing machine may generate corresponding fees according to the demand information; for another example, a sharing bicycle cannot know the use time of the user in advance, so that the cost of the user cannot be determined in advance.

For the scheme of the user who pays again after using the shared device, reference may be made to the existing scheme, and details are not described here.

For a scheme where the user pays first to reuse the shared device, see the following example.

In the above embodiment, when the cloud server provides the password to the user after the user completes payment, step S104 specifically includes:

and when the fact that the user pays the fee is detected, extracting the password corresponding to the demand information from the cloud password group.

Based on the embodiment, the cost and the password are extracted from the cloud password group according to the user requirements, for example, the washing machine is shared, the cloud server can search a corresponding cost which needs to be paid by the user from the cloud password group according to the washing time, the rotating speed and the washing temperature selected by the user, and the cloud server can provide the user with the corresponding password after the user pays successfully.

Wherein, expense, the password, the corresponding relation in high in the clouds password crowd and high in the clouds password storehouse can refer to the schematic diagram that fig. 2 shows, in fig. 2, high in the clouds password storehouse includes a plurality of high in the clouds password crowd, if cloud password crowd 1, high in the clouds password crowd 2, … … high in the clouds password crowd X, each high in the clouds password crowd corresponds a user, a plurality of users correspond a plurality of high in the clouds password crowd, in practical application, all high in the clouds password crowd can arrange successively according to the rank and make up into high in the clouds password storehouse, each high in the clouds password crowd is for the set of all passwords that produces according to predetermineeing the password generation rule to sharing device under the permutation and combination of different behavior, also contain all the circumstances that the sharing device was used to the demand of user in each high in the clouds password crowd, for example, high in fig. 2 cloud password crowd X, the different behavior of sharing device includes the factor: (1) the duration of use of the shared device, such as 5 minutes, 10 minutes, 20 minutes; (2) the number, for example, the number of the laundry machines shared, may refer to the number of the laundry items, such as 1, 2, and 3; (3) variables (such as variable 3 and variable N in fig. 2) refer to factor variables that affect the operating mode and cost of the shared device, different durations may be considered as one element under a certain variable, and a variable may include multiple elements, such as element a, element b, element c, and the like. The permutation and combination of the different factors generates a password and a unique fee corresponding to the password, as shown in fig. 2, a password a corresponds to a fee a, a password b corresponds to a fee b, a password c corresponds to a fee c, a password d corresponds to a fee d, and a password e corresponds to a fee e.

It should be noted that, the cloud server corresponds to at least one sharing device, the cloud server and each sharing device may form a system, the cloud server and the sharing devices form multiple systems, in practical applications, the same system ensures that the preset password generation rules (including the algorithm for password generation and the encryption principle) adopted by the device side password library and the corresponding cloud side password library are consistent, and the preset password generation rules may be different between different systems. In addition, it is also necessary to ensure that the passwords in a certain number of cloud password groups continuously generated by the cloud password library cannot be repeated.

Preferably, in the above embodiment, all the cloud password groups in the cloud password library and all the device-side password groups in the device-side password library may adopt the same password classification and classification scheme, that is, for the same requirement information of the same user, the corresponding cloud password groups and device-side password groups have the same level, and the passwords in the cloud password groups and the passwords in the device-side password groups have the same preset password generation rule, but the time for generating the passwords in the cloud password groups and the passwords in the device-side password groups may be the same or different.

In order to conveniently search the password, in practical application, for the scheme of paying first and then using the shared device, the user level can be determined according to the sequence of payment completed by the user, when a plurality of users need to pay, the payment time of the users is earlier, the corresponding user level is higher, and the user level is the same as the level of the corresponding cloud password group and the level of the device-side password group.

Referring to fig. 3, a schematic diagram of a correspondence relationship between a cloud server and a sharing device is disclosed in an embodiment of the present invention, where fig. 3 only shows a correspondence relationship between one cloud server and one sharing device, in practical applications, one cloud server may correspond to a plurality of sharing devices, and the plurality of sharing devices are separately managed in a cloud code library corresponding to the cloud server, so as to complement each other.

As can be seen from fig. 2 and fig. 3, when the user inputs different required information to the cloud password library, such as time, working mode, quantity, variable three, variable four, and the like, different passwords may be obtained from the cloud password library, where different users may obtain different passwords, such as user 1 obtaining password 1, user 2 obtaining password 2, user 3 obtaining password 3, user 4 obtaining password 4, user 5 obtaining password 5, and the like.

In practical applications, the cloud password groups may be classified into levels, and the levels of the cloud password groups gradually increase along the direction indicated by the arrow in fig. 3, and since one cloud password group corresponds to one user and each user acquires a password from the corresponding cloud password group, the levels of the passwords 1 to 5 gradually increase in the embodiment shown in fig. 3.

On the shared device side, the device-side password library includes a plurality of device-side password groups, such as device-side password groups 1-5, each device-side password group corresponds to one user, such as device-side password group 5 corresponds to user 5, and the preset password generation rules adopted by the passwords in the device-side password group and the passwords in the cloud-side password group are the same.

If the cloud-side password group is classified, the device-side password group may be classified accordingly, and the class of the device-side password group is gradually increased along the direction indicated by the arrow in fig. 3.

The user level, the equipment-side password group level and the cloud-side password group level are the same.

In practical application, the peer user uses the peer device-side password group, and the peer device-side password groups may be rotated normally, and of course, in some cases, the user may use the device-side password group more than the peer device-side password group, for example, the user 2 in fig. 3 should use the device-side password group 2 normally, however, in some cases, the user 2 may also use the device-side password group 3, and at this time, the device-side password group 1 and the device-side password group 2 of lower level may be placed in the valid password reserved area for the next use.

In order to further optimize the above embodiment, when it is detected that the user has paid the fee, a process of extracting a password corresponding to the demand information from the cloud password group may specifically include:

when the user is detected to pay the fee, extracting the password corresponding to the demand information from the cloud password group, and marking the user level, wherein when a plurality of users need to pay, the user level is determined according to the payment completion sequence of the users, and the closer the payment completion time of the users is, the higher the corresponding user level is.

It should be noted that the password provided by the cloud server to the user is extracted from the cloud password group corresponding to the user level according to the requirement information input by the user, for example, the shared washing machine, and the requirement information of the user includes: the washing time is 30 minutes, the rinsing is performed for 2 times, the dehydration is performed for 1 time, and the cloud server extracts the corresponding password from the cloud password group corresponding to the user level according to the demand information.

Correspondingly, step S105 specifically includes:

and feeding back the password to the user so that when the user uses the sharing equipment to be used, the sharing equipment to be used searches whether the password identical to the password is stored or not from an equipment side password library of the user by using the password, and if so, determining the user level and the requirement information of the user to finish the synchronous verification of the password.

When the user inputs the password to the sharing device, the password can be input in a digital form, or the sharing device can perform self-service identification according to a two-dimensional code certificate generated after the user pays the fee, or the password can be input in a voice identification mode.

It should be noted that the passwords are not arranged in a hierarchical manner in the device-side password group, and only after the passwords are input to the sharing device by the user and determined to be used, the passwords have a hierarchical degree, and the levels of the passwords are the same as the levels of the corresponding device-side password group.

Referring to fig. 4, a flowchart of a password authentication method for a shared device according to another embodiment of the present invention is disclosed, where the method is applied to a shared device to be used, such as a shared bicycle, a shared electric vehicle, a shared washing machine, and the like, and the method includes the steps of:

step S201, acquiring a password acquired by a user in a cloud password library;

the password is obtained by adopting a preset password generation rule on demand information in advance, and the demand information is the demand information of the user on the sharing equipment to be used.

The process of the user obtaining the password in the cloud password library can refer to the embodiment shown in fig. 1, and details are not repeated here.

Step S202, searching whether a password identical to the password is stored or not from a device side password library of the user by using the password;

the device side password library comprises a plurality of device side password groups, each device side password group corresponds to one user, all passwords stored in the device side password library by each sharing device and passwords in the cloud password library corresponding to the sharing device are generated by the same preset password generation rule for the requirement information of the users, and therefore the sharing device can determine the requirement information of the users according to the passwords acquired from the cloud password library by the users and the preset password generation rule.

In this step, the purpose of determining whether the password library of the device side of the sharing device stores the password identical to the password input by the user is to: and judging whether the password input by the user is a valid password.

And step S203, if so, determining the requirement information of the user by using the searched password and the preset password generation rule, and completing the synchronous verification of the password.

The cloud password library comprises a plurality of cloud password groups, each cloud password group corresponds to one user, and each cloud password group is a set of all passwords generated by the sharing equipment under different working conditions according to preset password generation rules.

When the password identical to the password is not found from the equipment side password library, prompt information is output, and the prompt information is used for prompting a user to input the password again.

As shown in fig. 3, in practical applications, a valid password reserved area may be set in the device-side password library, when it is necessary to determine whether a password input by a user is stored in the shared device to be used, the user may preferentially search in the valid password reserved area, and if the user does not search in the valid password reserved area, the user may search in a device-side password group that is generated by the device-side password library and is not located in the valid password reserved area.

Wherein, the valid password reservation area is mainly used for reserving the password which is acquired but not used by the shared device to be used.

Therefore, to further optimize the above embodiment, step S202 may specifically include:

and searching whether the password identical to the password is stored or not from the equipment side password group placed in the effective password reserved area of the equipment side password library by using the password.

Step S202 may further include:
