You may have heard the term LUDS in police shows, investigations by law enforcement, or through your local phone company. It is easy to understand why law enforcement would need access to phone company data since they use certain data for their analyses.

It is important to keep in mind that using your phone, whether it be a landline or a cell phone, leaves a trail of information behind. This information can be used to pinpoint vital information that law enforcement needs in the course of an investigation.

Are you wondering exactly what LUDS are and how they may affect you? Keep reading to learn more.

What Are LUDS?

LUDS, or Local Usage Details, can provide both the phone company, service provider, and law enforcement with quite a bit of information on individuals. This is because this report is generated to give specific information about the location and contact information of an individual.

In essence, as you use your landline or cell phone, the data is tracked and kept on file for a specific period. This information can then be used for various purposes including creating your bill and providing law enforcement with pertinent information they need in solving a crime.

The bottom line is that LUDS gives track data from any outgoing and incoming call or text message that you make or receive. This information can then be used to provide certain information about where the specific phone was and when.

What Types of Information Can You Find in LUDS?

You may be surprised to learn just how much information can be found in the LUDS that are associated with your phone. Keep in mind that this information is used for various purposes and is not intended to be used for nefarious means.

Here is some of the information you may find on LUDS:

• Incoming and outgoing call logs
• Details from local calls such as location and time
• International call data
• Rates of certain calls
• Duration of calls
• Toll information and other fees or charges

As you can see, there is quite a bit of information that is contained in the Local Usage Details that are generated by your local phone company or service provider.

How do Phone Companies Use LUDS?

Since phone companies are the ones who generate LUDS, it makes sense to understand the purpose behind it. Keep in mind that these companies are in the business of providing you with phone service and thus have certain rights and responsibilities.

These rights and responsibilities include tracking specific data, as previously mentioned, to generate your bill. They use the information to keep track of how you are using the phone to ensure that you are being charged correctly.

Other data they collect may not have anything to do with the individual user of the phone but are used to collect data from the towers and other equipment used to make the calls. Doing this gives them more information about how their equipment is working and when there may be a problem.

Overall, phone companies and service providers do track your data, but with the sole purpose of ensuring that you are getting the best service and to ensure that you are billed correctly. For them to provide you with the best service, they have to use LUDS.

How Can LUDS Be Used During Police Investigations?

In some cases, phone companies and other service providers are required to share LUDS with law enforcement for their investigation purposes. Because of this, it is important to keep in mind that they are legally bound to provide the information.

During the investigation of a crime, law enforcement representatives will often choose to use LUDS to help them. The information that is provided in the LUDS can be useful in helping them to narrow down a suspect pool having to do with certain crimes.

It is important to keep in mind that police officers and detectives are not just allowed to pull the records without probable cause. They are required to get a court order and explain why they need the records before a judge will sign off on the order.

Once they have received the court order, the phone company or service provider is required to give law enforcement the requested LUDS. This information is then used to help them gain more information about certain individuals that may be associated with the crime.

In most cases, detectives use LUDS in a few different ways, depending on the investigation.

Gives Location of Individual

One method law enforcement can use LUDS to help with the investigation is through the location detail the report provides. Since LUDS are used to verify what tower a cell phone call was made from, they can then decide if an individual was in the vicinity of the crime.

LUDS can also be useful to law enforcement agencies by narrowing down a list of suspects in an investigation. Since most people provide an alibi for themselves, LUDS can often be used to prove that a person was where they say they were.

Provides Historical Data on an Individual

Another piece of evidence that can be provided through the use of LUDS is various historical data on individuals. This means that detectives can sift through the details for certain individuals to establish a pattern of behavior that can be useful in solving a crime.

The historical data that is often used is the location of a certain individual over time. If they have historically been in a specific location over time, it can be used to establish the behaviors of the individual to determine whether or not they are linked to the crime in question.

Shows a Link Between Individuals

Other information that can be provided through the use of LUDS is the specific link that one individual has to another. Since some of the details in the LUDS includes who the individual has called or received calls from, it can establish a relationship between them.

This information is often used by law enforcement to determine whether or not a certain person has more information than they have revealed during an investigation. Additionally, this information can tell detectives just how close of a relationship two individuals have based on the call frequency between them.

What About Data Privacy Laws?

A question that is often asked about the use of LUDS is whether or not using them breaks certain data privacy laws. The quick answer to this question is that the existence of LUDS does not break any laws since the information is used honestly, in most cases.

Since phone companies are in the business of providing you with certain services, they have the legal right to track your data for billing. While this means that they have access to your personal information, they also have certain regulations and responsibilities to you.

This means that unless the court orders you to provide the information, they are not allowed to release your information to anyone. This means that the information they collect from your phone usage stays within their company and is protected by certain regulations they have in place.

It is important to keep in mind that when the information is requested by law enforcement, they must have a court order to do so. This means that they will have had to see a judge and make a case that having access to your LUDS is important to the investigation of a crime.

The bottom line when it comes to data privacy laws is that even though the phone company is in the business of protecting this information, it must also use it for various purposes. In most cases, the information is used to ensure you are getting the best service from them and that you are being billed correctly.

LUDS Have Limited Information

It may be important to note that while LUDS provides quite a bit of information about the whereabouts of your phone daily, the information can be quite limited. This is because the data provided in a LUDS is mostly basic.

While LUDS can provide information on the location and time of where the phone has been, there is even more information that can be found on the individual device. This means that while law enforcement and service providers can find out general information using LUDS, they may be missing some vital information.

This is especially true when it comes to cell phones and what is stored on the individual devices themselves. While LUDS can give the basic information, an actual device can provide much more detailed data that is often more useful.

It is also essential to keep in mind that while LUDS provides location information, it is not as specific as the GPS information on the device itself. This is because LUDS can pinpoint only a specific tower a call was made from and not the exact location.

Overall, while LUDS has its uses for both phone companies and law enforcement, they often provide only certain information. Even though they have been used for many years by law enforcement agencies, they are limited in the amount of data they can provide and are often not the only source of information used to solve a crime.
