Privacy leakage protection method based on data traceability

Abstract

The invention discloses a privacy leakage protection method based on data traceability. A smart home platform is taken as an example. The method comprises log fusion generated by operation of intelligent household appliances (such as an intelligent sound box, an automatic curtain and an intelligent electric lamp) and control instruction detection of a cloud center. The method is characterized by comprising: performing static stain analysis on the control instruction of the cloud center; searching a data leakage condition (such as a password manually input by a user) possibly generated at a code level; secondly, searching a corresponding logic relationship for all events occurring in a user room at a code level by using a data traceability technology; integrating the scattered intelligent household appliance logs according to the causal relationship of the event; obtaining a complete centralized log system (a causal chain set of event occurrence) under the platform, then using the log system for judging behaviors already occurring in a user room, determining whether the behaviors are normal behaviors or not, and therefore a user can be informed of the abnormal behaviors, and the user is assisted in effectively protecting the privacy safety of the user.

Description

technical field [0001] The invention belongs to the field of smart home security, relates to smart home equipment, and in particular to a security system for effectively protecting privacy data of smart home platform users based on a privacy leakage protection method based on data traceability. Background technique [0002] Smart home is one of the more popular Internet of Things platforms at present. As the Internet of Things and human life become closer and closer, more and more smart home devices (such as smart refrigerators, smart cameras, smart thermostats, etc.) enter the family. Although these smart devices provide people with great convenience, we cannot turn a blind eye to their potential safety hazards. The development of smart home products in my country is still in its infancy, and the technical level is relatively low. Moreover, most of the smart product manufacturers are start-up companies with relatively small funds and limited investment in solving security v...

Problems solved by technology

In addition, the Internet of Things faces more and more complex threats due to its constantly emerging new features, and the terminals are more scattered. The low-level terminal logs cannot form a complete explanation of the attack behavior in this environment, so we very much It is necessary to think about a suitable method to solve the security risks existing in the smart home environment
