The present disclosure relates to a hand-gesture-based interaction method and apparatus, and a client. The method includes: in a live stream process of one network live stream, when a function of playback of a hand gesture animation is in an activated state, a client of an anchor user recognizes a hand gesture of the anchor user. When a hand gesture category matches a preset category of the hand gesture animation, the client of the anchor user plays back the hand gesture animation in a first area corresponding to a hand gesture position, and transmits a first content to a client of a viewing user through a first server. The client of the viewing user, based on the first content, plays back the hand gesture animation in a second area corresponding to the hand gesture position, and detects a trigger operation on the second area.

The invention discloses a blockchain-based intrusion detection system for railway signal, which is built on a blockchain's distributed chain structure, without a central, trusted control center. This design mitigates the vulnerabilities associated with centralized intrusion detection centers. Additionally, by utilizing a blockchain-based distributed structure, it also eliminates the risk of a single point of failure for the intrusion detection center. Moreover, the data within the blockchain-based intrusion detection system is highly resistant to malicious tampering. This is achieved by leveraging the consensus mechanism inherent in the blockchain, which can achieve consensus among intrusion detection nodes. The current invention solves the internal evil attacks and avoid the inability to reach consensus between nodes due to internal evil, thereby affecting the intrusion detection performance; at the same time, the intrusion detection model can resist external network attacks.
