We developed a secure online multimedia event detection (MED) system. Our novel Tree Proxy-based and Service-oriented Access Control (TPSAC) model and 1000-Object-Bank (1000OBK) descriptor enhance security and event representation.

Area of Science:

Computer Science
Multimedia Systems
Information Security

Background:

Integrating traditional event detection algorithms into online environments presents challenges in secure access control and robust representation.
Existing methods lack adequate security measures and scalable, effective feature descriptors for multimedia event detection (MED).

Purpose of the Study:

To address the secure access control and large-scale robust representation issues in online multimedia event detection.
To propose and validate novel solutions for enhancing the security and representational capabilities of MED systems.

Main Methods:

Developed a Tree Proxy-based and Service-oriented Access Control (TPSAC) model, extending traditional role-based access control.
Proposed a 1000-Object-Bank (1000OBK) event descriptor inspired by object-bank scene descriptors, utilizing generic object detectors and a spatial bag-of-words approach.
