[{"type":"text","content":"BEIJING, Sept. 13, 2023 /PRNewswire/ -- WiMi Hologram Cloud Inc. (NASDAQ: WIMI) (\"WiMi\" or the \"Company\"), a leading global Hologram Augmented Reality (\"AR\") Technology provider, today announced that a new technology called attribute key access control (AKAC) has been developed. This technology will provide a new solution for data security and flexible access control. The technology is an innovative advancement in attribute-based encryption (ABE) that brings unprecedented flexibility, fine-grained control, and high performance to access control.\n\nWiMi's AKAC technology is a further development of ABE, which employs a novel access control approach that combines the association of attributes and keys to provide more flexible and fine-grained data access control for users. In the AKAC, it is first necessary to define various attributes, which can be features describing the user's identity, role, geographic location, and so on. Then, the system associates these attributes with an access policy for the data and decides whether to allow access and decrypt the data based on the attributes possessed by the user. The AKAC allows combining multiple attributes in an access policy and using Boolean logic to perform logical operations on these attributes to realize complex access rules.\nThe core of AKAC is the generation and management of attribute keys. The system dynamically generates attribute keys based on user attributes and access policies instead of fixed role keys. In this way, even if the user's attributes change, such as position adjustment or authority change, the system can instantly update the attribute key to ensure real-time and accurate access control.\nWiMi's AKAC technology brings many advantages as an innovative access control mechanism:\nFlexible fine-grained access control: AKAC allows access rights to be defined based on user-specific attributes, realizing flexible fine-grained access control. Users can set access policies based on different combinations of attributes to ensure that only users who meet specific conditions can decrypt and access data. This allows access control to be better adapted to different application scenarios and provides personalized access rights.\nData owner control: AKAC technology empowers data owners to directly control the access policies and encryption methods for their data.
