Method and Apparatus for Identifying and Monitoring VOIP Media Plane Security Keys for Service Provider Lawful Intercept Use
ActiveUS20070297418A1Easy to identifyHigh security riskTime-division multiplexData switching by path configurationService providerNetwork element
A mechanism is described that enables encrypted end-point communications in a VoIP network to be accessed by a service provider. The mechanism includes a session information retrieval component which gathers session information such as encryption keys for each session that traverses a network element. The encryption keys may be used to decrypt data to make it available for lawful interception. A media stream monitoring component monitors media streams and verifies that the identified keys for each session are valid, to ensure continuity in compliance with LI regulations. Advantageously a security alert component may be used to controls further session operation for those sessions identified as potential security risks. With such an arrangement, the service provider can satisfy the legal requirement to provide interception, verify that the accuracy of the legal interception support and take appropriate steps to handle security risks.

A radio frequency (RF) device includes an RF transceiver, an RF antenna, and a magnetic signal detector. The RF is selected to be in the very high frequency (VHF), ultrahigh frequency (UHF), or super high frequency (SHF) bands such that the shielding effect is reduced and the RF device can be configured as a SIM card disposed inside a cellular phone with an increased RF communication range. The magnetic signal detector is used to sense a magnetic field signal from an RF reader, which includes an RF transceiver, an RF antenna, and a magnetic signal transmitter. The longer communication range afforded by the VHF, UHF, or SHF bands is reduced by the sensing of the magnetic field, thereby providing a communication range control, while the RF device and the RF reader exchange information through the RF channel with improved security as a result of the range control.

ActiveUS10440029B2High security riskTransmissionSpecial data processing applicationsIdentity management systemDatabase
An identity management system is augmented to provide for automated suspension of all dormant accounts before launching a re-certification campaign (pass). In one implementation, prior to receiving a recertification notice from the system, the affected user's account is already suspended and thus cannot be accessed. Once the recertification succeeds, however, the account is restored. Preferably, the technique is exposed to an IAM system administrator through a simple interface, e.g., a one-click “suspend and re-certify” button in an administrative menu. When the administrator initiates the re-certification process, he or she may select the button for a particular account or user.
