Cell phone detection and identification
First Claim
1. A combination of a security tag and a mobile phone for monitoring, tracing, and securing the mobile phone within a protected physical location, wherein the security tag is affixed to the mobile phone and comprises:
- a tag antenna operable at a low radio frequency not exceeding one megahertz;
a tag transceiver operatively connected to the tag antenna, the transceiver operable to receive radio signals at the low radio frequency and generate data signals at the said low radio frequency, in response thereto;
a microcontroller operatively coupled with the transceiver, the microcontroller being configured to cause the transceiver to emit a signal when the mobile phone is exiting the protected physical region, anda memory having stored thereon a security program for controlling access to data stored in the mobile phone, wherein the security program permits access to stored data in the mobile phone when the mobile phone is within the protected physical region and restricts access to stored data in the mobile phone when the mobile phone is outside the protected physical region.
