Abstract

The invention relates to a smart home evidence obtaining method based on an ontology, and belongs to the technical field of the Internet of Things. The method comprises the following steps: S1, acquiring smart home equipment data; s2, analyzing intelligent equipment data in the intelligent home environment; s3, uniformly expressing the evidence based on the ontology; s4, abstracting an evidence obtaining mode; and S5, sharing and applying evidence obtaining investigation. A unified representation method of different data formats generated by different smart home devices is provided based on ontology. The evidence integrity is fused to ensure the hash value, so that evidence sharing, transmission, exchange, management, evidence presentation and the like of case management among evidence obtaining investigation and other related personnel in the same case, the same case and different cases can be more effective and standardized, and the problem of data heterogeneity in smart home evidence obtaining is solved. The evidence obtaining mode based on ontology attributes effectively solves the problem of data sensitivity of smart home evidence obtaining knowledge sharing.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things and relates to an ontology-based smart home forensics method. Background technique [0002] With the development of IoT technology, IoT devices are becoming more and more common. More and more people live in smart homes. Many devices are connected through the Internet of Things. These devices generate a large amount of data, which is also a potential source of evidence. Therefore, for The digital forensic investigation in the smart home environment is particularly important, however, the current forensic methods for the smart home environment have the following deficiencies: [0003] First of all, due to the heterogeneity of smart home devices, different devices have different data storage formats, and there is currently no unified evidence data representation format, which is not conducive to evidence sharing; [0004] Secondly, most of the existing research focuses on the concept...
