  • Patent number: 8819824
    Abstract: A system to detect and analyze RF signals utilizes a data structure storing RF signatures indicating characteristics of known authorized and/or unauthorized RF transmissions. When an RF signal is detected, certain analysis characteristics are extracted from the RF signal and analyzed with respect to the stored RF signatures to determine whether the RF transmission is authorized or unauthorized. In the event of an unauthorized RF transmission, the system generates an alarm condition to alert the user to an RF intrusion and may further log data related to the intruder transmission. Known techniques may be used to determine the location of the RF intrusion within a defined area of operations.

  • Patent number: 8496169
    Abstract: An enhanced security system utilizes a consumer wireless device and independent secure servers to enhance identification and authentication of the electronic ticketing. The consumer may make an eTicket purchase using a network, such as the Internet, in a conventional manner. The server involved in the purchase may send an eTicket confirmation to a consumer wireless device. However, master records of the transaction are sent via a secure link to a vendor server, typically associated with a wireless service provider. At a point just-in-time, the vendor server transmits symbology to the consumer wireless device and transmits additional data related to the symbology to a security server. When the consumer arrives with the eTicket, the consumer also uses the displayed symbology on the consumer wireless device. The symbology is scanned and compared with data transmitted from the vendor server to the security server. If authenticated, the eTicket may be authenticated.
