Disclosed is a system to capture cellular broadcasts and record the unique identifiers (IDs) of mobile devices when a significant event occurs. Investigators can then obtain the IDs, identify the device user or owner, and possibly identify a witness to the event and gather information.

Capturing Electronic Device Identities When Events Occur

When a particular event happens (e.g., a crime, accident, or other activity) authorities often have difficulty locating witnesses. For example, with an automobile

accident, unless a witness stops to help or waits in the area, that witness probably cannot be found.

Current solutions rely upon either video evidence, which may or may not be

available from passersby or public cameras, or the recollection of those involved in the event to help identify and locate witnesses.

To help identify who might have been within the vicinity of a particular event, such as an auto accident, it would be useful to detect and record the mobile devices that

were within range when the event occurred. There is a high probability that one or more users of these devices witnessed the event. Cell phones have Wi-Fi and Bluetooth radios. Other cell phones nearby can receive these broadcasts and record a unique identifier such as a Media Access Control (MAC) address of the devices.

The novel contribution is a system to capture these cellular broadcasts and record the unique identifiers (IDs) when an event occurs. With this information, investigators can reference the databases of the carrier or manufacturer and identify the owner or user of the device. Then, an investigator can contact the owner or user and possibly obtain more details about the event.

At a high level, the process flow of the system is:

1. Event detection

2. Capture request

3. Receiver captures IDs

4. Identify owner/user from ID

Following are the components and steps for implementing the system for event detection and capture with electronic devices. In a preferred embodiment, given that a particular event occurs:

1. A capture request is produced by any number of methods
A. Cellular phone, on which the us...
