Description
Technical Field
The invention relates to a system for preventing loss, in particular to a method and a system for preventing loss of two-dimension codes based on a public platform.
Background
With the coming of aging society, the problem that the old people get lost is increasingly serious. At present, means or technologies for preventing the old from being lost mainly comprise an information card, a positioning terminal, application based on a report terminal and the like. The three means or technologies have certain defects and limitations, for example, the information card is generally placed in a pocket, so that people can hardly find the information card, the recorded information is limited, and the information is difficult to update; the positioning terminal is high in price, inaccurate in positioning, short in standby time and prone to failure; the application based on the report end also has the defects of difficult popularization of the report end, difficult verification of the identity of a reporter and the like.
Disclosure of Invention
The invention aims to provide a two-dimensional code anti-lost method based on a public platform.
The invention also aims to provide a public platform-based two-dimensional code anti-lost system based on the lost method, and provides a safe, convenient and efficient old people anti-lost method.
In order to achieve the purpose, the invention provides a two-dimensional code anti-lost method based on a public platform, which mainly comprises an information access control method and an old people lost judgment method;
the information access control method sets two information access modes; allocating one or more roles for a user, setting corresponding access authority for each role, independently setting security level for each piece of information of the old, only allowing the user with the role access authority greater than or equal to the information security level to access, and allowing a system and an information creator to dynamically adjust the information security level of the old;
the two information access modes are external code access and internal code access;
the outer code access is a two-dimensional code exposed in the air through a code scanning, such as a two-dimensional code printed on clothes, badges worn on T-shirts and other articles, and the two-dimensional code comprises plaintext information, hidden ciphertext information and anti-lost platform links (corresponding to old people information numbers, outer code identifications and the like); (ii) a
The internal code access means that the old people actively present the two-dimensional code by scanning the code, and the two-dimensional code comprises plaintext information, hidden ciphertext information and anti-lost platform link (corresponding to the information number of the old people, the internal code identification and the like);
the security level is represented by a number, for example, 0-8, and the larger the number is, the higher the required access authority is;
the access authority is represented by a number, for example, 0-8, and the larger the number is, the higher the access authority is;
the dynamic adjustment of the information security level of the old people reduces the security level of main information when the old people are lost, is convenient for more visitors to read and provides help;
the main information security level reduction comprises names of the old people, contact ways of guardians, telephone numbers of community dispatching places of residential cities of the old people, physical health conditions of the old people and cautionary matters;
the information access control method is characterized in that the system classifies the information of the old and guardians and sets the security level of each piece of information. The security level of the information is represented by a number, with a larger number indicating higher access rights to the information. For example, the security level of the name of the city community where the old people live is 0, the default security level of the call sent by the community is 2, the default security level of the contact call of the guardian is 3, the default security level of the number of the identity card of the old people is 5, and the default security level of the return payment is 8.
If and only if the authority of the role or role group is greater than or equal to the information security level, the user owning the role or role group has the authority to access the information. For example, if the authority of the visitor to the plaintext information of the external code is 0 and is smaller than the security level 3 of the contact phone of the guardian, the visitor to the plaintext information of the external code cannot read the contact phone of the guardian, i.e., the system cannot write the contact phone of the guardian into the plaintext of the external code. The visiting authority of the internal code link visitor is 3, and is more than or equal to the security level 3 of the contact telephone of the guardian, the internal code link visitor allows the access to the contact telephone of the guardian; meaning that a user logged into the public platform through an internal code link is allowed access to the guardian's contact phone. The creator of the information has the highest authority 8 on the information it creates, and the creator of the information can also define roles or groups of roles and grant them temporary access, such as the authority granted to the parent role group 7.
Table 1 partial roles or groups of roles and corresponding permissions
| Roles or groups of roles | Access rights |
| Visitor to plaintext information of outer code | 0 |
| Visitor of hidden information of outer code | 2 |
| Outer code link visitor | 2 |
| Visitor to plaintext information of internal code | 2 |
| Internally coded ciphertext message visitor | 4 |
| Intercode chaining visitor | 3 |
| Information creator | 8 |
| Real name authentication volunteer | 4 |
| Real name authentication policeman | 5 |

The method for judging the missing of the old people adopts the following strategy to judge:
when the guardian logs in the missing of the old people, the old people are judged to be missing;
when any user accesses through the internal code, the old man is judged to be lost;
when a police or volunteer with real-name authentication accesses the code through the external code and actively reports the loss, the old is judged to be lost;
when the external code access address exceeds the daily activity range of the old, the external code access frequency is higher than the daily access frequency, and the external code access time is abnormal, the system judges whether the old is lost or not through a loss prediction model;
the loss prediction model adopts offline training to complete a support vector machine model, and input vectors are formed by four input parameters of ACDN;
the mobility A is represented by a number, such as 0-100. Wherein, 100 represents normal action ability, 0 represents complete loss of action ability, and the evaluation score is given by the guardian;
and the cognitive competence C is represented by a number, such as 0-100. 100 represents that the cognitive ability is normal, 0 represents that the cognitive ability is almost lost, and the evaluation score is given by a guardian after testing the old;
the deviation distance D represents the distance of the code scanning place deviating from the daily activity range of the old; the initial value of the daily activity range of the old is set by a guardian or is measured by positioning equipment, and the daily activity range of the old is dynamically updated subsequently along with the application of the system;
the code scanning frequency, N, represents the number of times a certain period is scanned.
The invention also provides a public platform-based two-dimensional code anti-lost system based on the method, which is characterized in that:
the system consists of subsystems and public platform interfaces, wherein the subsystems comprise user account management, user authority management, two-dimensional code distribution, statistical analysis, loss judgment and the like;
the user account management is used for completing user registration and management of the user account;

the statistical analysis is used for completing the statistics of activity routes and access behaviors of the old and malicious behavior detection;
the malicious behavior detection method comprises the following steps:
(1) the access frequency is greater than a threshold value;
(2) reported by others, and the results are verified to be true;
(3) actively reporting the loss for many times, but proving to be false after the fact;
(4) and acquiring that the visitor has bad records from other channels.
