Big Data for Tracking Criminal Activity

Big Data and the Government

Introduction

In recent years, there has been an explosion of data generated by disparate sources, including social media, financial transactions, and sensor networks. This so-called Big Data has the potential to transform the way in which governmental agencies operate. For example, the Department of Homeland Security (DHS) has used Big Data to thwart terrorist attacks, by mining social media for suspicious activity. The Department of Health and Human Services has used Big Data to combat fraud in the Medicare system. And the Department of Education has used Big Data to improve student outcomes. With its ability to identify patterns and trends, Big Data has the potential to make government more efficient and effective. As the volume of data continues to grow, so too will the opportunities for government to harness its power. This paper will look at how Big Data can be used to improve DHS.

Background on the DHS

The Department of Homeland Security (DHS) is a federal government agency tasked with protecting the United States from terrorist attacks and other hazards. The agency was created in response to the 9/11 terrorist attacks, and it currently employs over 240,000 people. The DHS is responsible for a wide range of activities, including border security, counterterrorism, disaster response, and cyber security. The agency also administers the U.S. visa system and provides funding for state and local law enforcement agencies. In recent years, the DHS has come under criticism for its handling of immigration and border security issues. However, the agency remains an important part of the federal government's efforts to keep America safe (White, 2016).

Big Data

Big data is a term that describes the large volume of data that organizations and individuals create. But it is not just the size of data that is important. Big data can also refer to the variety and velocity of data. Variety refers to the different types of data that are being created, such as text, images, and videos. Velocity refers to the speed at which data is being generated, collected, and processed (Sagiroglu & Sinanc, 2013). Together, these two characteristics provide a wealth of information that can help organizations understand what is going on in the world (Kaisler et al., 2013). For example, by tracking the variety of data types relevant to an organization (e.g. targeted population demographics, purchasing history, website traffic, etc.), an organization can gain a better understanding of their target population and what kinds of issues or activities are most popular with the population. Additionally, by monitoring the velocity of data collection (e.g. how quickly customer needs change, how fast new products are adopted, etc.), they can anticipate population needs, desires, and demands and adjust policy accordingly. In this way, big data provides a valuable tool for organizations to make informed decisions about their operations.

The term "big data" is often used in reference to the technology and methods used to store, manage, and analyze large volumes of data. However, big data can also refer to the organizational opportunities that arise from working with large datasets. With the right tools and methods, organizations can use big data to gain insights into population behavior, improve operations, and make better decisions.

How Big Data Can Improve DHS

Big data has the potential to transform the way that the Department of Homeland Security (DHS) operates. By harnessing the power of data analytics, DHS can improve its ability to identify and respond to threats. For example, data can be used to improve situational awareness and target resources more effectively. In addition, data analytics can help DHS to detect and investigate potential threats before they materialize. By harnessing the power of big data, DHS can become more efficient and effective in its mission to protect the homeland.

Specifically, Big Data can be used to thwart terrorist attacks, by mining social media for suspicious activity. In the wake of the 9/11 attacks, the United States government has made combating terrorism a top priority. A key part of this effort has been the use of Big Data to track and identify potential threats. By mining social media for Suspicious Activity Reports (SARs), law enforcement agencies can flag potential threats and take preventative measures (Coulthart & Riccucci, 2022). Through analyzing large sets of data, it is possible to identify patterns and trends that might otherwise go unnoticed. For example, by monitoring social media posts, it is possible to track the spread of misinformation or identify potential threats. In addition, by analyzing the data from social media posts, it is possible to gain insights into the behavior of people and groups. This information can be used to improve public safety or to prevent crime. For example, in 2015, the FBI was able to thwart a terrorist attack on a cartoon contest in Texas, thanks to a tip-off from social media. While Big Data has been criticized for invade privacy, when it comes to thwarting terrorist attacks, it has proven to be an invaluable tool (Joh, 2014).

Another way Big Data can be used to improve the DHS is that it can be used to track the movements of individuals across international borders. This information can then be used to identify potential security risks and take appropriate action. By analyzing data from cell phone towers, social media, and other sources, researchers have been able to create detailed maps of human mobility patterns. This information could be used by governments to better understand the flow of people across national borders. In addition, it could be used to identify potential security risks and prevent the spread of disease.

Big Data could be used to track the movements of money as well to see if any of it is being used for criminal activities (Aggarwal, 2019). By analyzing financial transactions, it may be possible to detect patterns of criminal activity. For example, suppose that a group of individuals is engaged in money laundering. By tracking the flow of funds, it may be possible to identify the individuals involved and bring them to justice. Similarly, big data could be used to track the movements of drug money or to locate the sources of funding for terrorist organizations. In short, big data has the potential to revolutionize law enforcement by providing a new tools for identifying and prosecuting criminals.

The DHS can use Big Data to develop predictive analytics tools that could be used for a range of purposes, including identifying potential terrorist threats and guiding law enforcement responses. Predictive analytics uses mathematical algorithms to analyze this data and identify patterns. This information can then be used to make decisions about policy development, how to track police responses to trends, and how public campaigns should be conducted (Joh, 2014).

However, the use of Big Data by the DHS coul also raise privacy concerns for many, as the agency has access to a vast amount of personal data that could potentially be used to unfairly target individuals. Therefore, it is important that politics not enter into the decision making of how Big data will be used. It should always be remembered that this data is often sensitive in nature, and its misuse could have serious implications for national security. As a result, it is essential that any decisions regarding its use are made free from political interference. Big data and predictive analytics should be governed by impartial experts who are able to weigh the risks and benefits of its use. So while keeping these concerns in mind, it is still clear that the use of Big Data can play an important role in the work of the DHS.

Conclusion

Big data has the potential to revolutionize the way that the Department of Homeland Security (DHS) functions. By definition, big data refers to extremely large data sets that may be too large or too complex for traditional data-processing techniques. However, with the right tools, this data can be analyzed to reveal valuable insights. For example, big data can be used to improve situational awareness by identifying patterns and trends that would otherwise be invisible. It can also be used to target resources more effectively, ensuring that limited resources are used as efficiently as possible. Big data can be used to analyze movements of money and people across borders to provide DHS with greater insight into potential criminal activities. It can be used to better understand social media activity so as to see how information and misinformation are being spread online and for what ends or purposes. By using Big Data, DHS could improve on a number of fronts, including crime prevention and the issue of pre-crime identification. In short, big data has the potential to transform DHS into a leaner, more effective organization. Given the importance of homeland security, this is an investment worth making. The main issue that DHS must be careful with is privacy, however. There is a fine line between gathering analyzing as much data as possible, and prying too much into the private lives of citizens. After all, it was Edward Snowden who blew the whistle on government spying years back—so DHS has to be careful not to create another scandal like the one brought on by the NSA.
