With the rapid advancement of information technology, humanity has transitioned into an information-driven society. This transformation has reshaped how people live and work, influencing political, economic, and technological landscapes across the globe. Over time, as both the Internet and IT have evolved together, vast amounts of data have been generated across various sectors. According to Gartner, a leading global research and consulting firm in information technology, the growth of big data is primarily driven by two factors: one is the massive data produced by consumers through activities like online shopping and social media; the other comes from urban infrastructure development, including security systems.
In the security industry, there is a wide variety of data types involved. These include unstructured, structured, and semi-structured data. Unstructured data consists of video recordings, images, and other multimedia content, such as surveillance footage, alarm logs, vehicle license plate photos, and facial recognition images. Structured data includes system logs, maintenance records, and databases containing population, geographic, and vehicle information. Semi-structured data involves elements like facial models and fingerprint records.
These data sources come from within the security system itself, such as video clips, snapshots, and system logs, or from external systems like population registries, geographic data, and vehicle management systems. Together, they form the foundation of big data in the security field. The most prominent characteristic is the sheer volume of data, which is growing rapidly due to the expansion of video surveillance networks and higher resolution and frame rates. Storage requirements have shifted from terabytes to petabytes. Additionally, the diversity of data types is increasing, and while the value density may be low, the potential value is immense. For instance, in 24/7 video monitoring, only a few seconds of footage might contain critical information.
To extract useful insights from this massive data, security vendors need to enhance their ability to process unstructured data efficiently, such as analyzing video and facial features. They must also improve big data platforms to enable fast retrieval and analysis of structured and semi-structured data, creating tailored architectures for security applications.
The application of big data in the security sector presents unique challenges. While IT industries focus on textual data, the security field emphasizes image-based information retrieval. Tools like video intelligence analysis, image sharpening, and video transcoding are essential for processing unstructured data. For structured and semi-structured data, the security community draws on IT practices to perform accurate and efficient analysis.
In projects like "Safe City," the integration of big data technologies helps manage and analyze massive video data, enabling faster decision-making and improved public safety. Cloud storage has emerged as a key solution, offering scalable and cost-effective storage for video and image data. Unlike traditional storage, cloud storage provides distributed, fault-tolerant, and highly available solutions, significantly reducing maintenance efforts and downtime.
Despite these advancements, the security industry still faces challenges in fully leveraging big data. Data remains fragmented, and standardized methods for mining and utilizing it are not yet established. Security companies must invest in R&D, enhance their technical capabilities, and develop robust systems to handle the growing data volumes effectively.
As the era of big data continues to evolve, the security field stands at a crossroads—facing both opportunities and challenges. The future will depend on how well the industry adapts to new technologies and integrates them into existing systems to ensure safer, smarter, and more efficient operations.
