Embodiment 1

[0099] Application of this method in WeChat

[0100] Divide all the visitors in the "nearby people" in WeChat into five categories: contacts in the mobile phone (saved phone numbers), WeChat friends, QQ friends, the same school or work unit in WeChat as the interviewee, unfamiliar people. This results in four roles: friends, known, colleague, unknown. The order of priority is as follows Table 2 shows the priority and authority assignment of roles in WeChat:

[0104] Table 2

[0105] According to the policy language above, the policy is constructed as follows:

[0106] Rule1: phone-number in Phone-Contacts->friends;

[0107] Rule2: WeChat-number in WeChat-friends->known;

[0108]Rule3: QQ-number in QQ-friends->known;

[0117] Application of this method in the taxi system

[0118] At present, the taxi-hailing system is widely used, but the system is simple, and generally you can only contact the customer service to call the driver of the empty car, which is very inconvenient and inflexible. But if the taxi information can be checked online, it will bring security problems. The current design is as follows: the driver's relatives can view all driver information; the driver's friends can view the current location to contact you; the operating company can view the driver's historical itinerary for unified scheduling; Check their mobile phone number for easy contact. The following table 3 shows the priority and authority assignment of roles in the taxi-hailing system.

[0133] Application of this method in online cinema

[0134] An online movie theater is currently open to the EU, US, Japan and China (other countries are not considered because of religious issues). Since China does not allow teenagers and children to surf the Internet alone, the movie theater stipulates that the role distribution of the online movie theater is as follows: Table 4

[0135]

[0136] Table 4

[0137] According to the policy language above, the policy is constructed as follows:

[0138] Rule1: age≥3 and country in{EU, America, Japan}->Child;

[0139] Rule2: age≥11 and country in{EU, America, Japan}->Juvenile;

[0140] Rule3: age≥16 and country in{EU, America, Japan, China}->Adolescent;

[0141] Rule4: age≥18 and country in{EU, America, Japan, China}->Adult;

Abstract

The invention discloses an access control method and system based on an attribute and a role. The method comprises the steps that for a plurality of users who bring up access resource requests, attribute strategies are designed according to the feature information of the users, and conflicting strategies in the attribute strategies are optimized; the attribute values of the users are obtained, and according to a preset attribute expression, whether the users have the right to carry out accessing is judged; if the users have the right to carry out accessing, according to the attribute distribution roles of the users and the roles, authority corresponding to the roles is checked, and accessing and obtaining of resource information by the users are achieved. According to the method, through the feature that ABAC can meet the requirement for large-scale dynamic accessing and the flexibility of RBAC authority distribution and management, access control mixed with the two parts is designed, and on the basis, the problems of strategy redundancy and conflicting are solved.

Description

technical field [0001] The invention relates to the field of access control of information resources, in particular to an access control method and system based on attributes and roles. Background technique [0002] With the rapid development of the Internet of Things, security issues have become increasingly prominent. For example, the disclosure of taxi information in the taxi-hailing system and the disclosure of location privacy in WeChat abound. However, the commonly used access control is mainly the access control in the Internet. For example: Role Based Access Control (RBAC for short), Attribute Based Access Control (ABAC for short) and so on. Among them, RBAC introduces the concept of roles between users and access rights. Users are associated with one or more specific roles, and roles are associated with one or more access rights. Roles can be generated or canceled according to actual work needs. Moreover, users who log in to the system can dynamically activate th...
