An anti-eavesdropping device is described. The device comprises a receiving compartment for receiving an electronic device, a noise generator, and an EMI filter. The receiving compartment is sealable to minimize signal emissions from the interior to the exterior and from the exterior to the interior, and the noise generator is coupled with the receiving compartment and the EMI filter. The EMI filter is operatively coupled with the noise generator.

1. A method of operation of an anti-eavesdropping device, the anti-eavesdropping device being constructed of materials to minimize transmission of electromagnetic and/or audio signals from an exterior of the device to an interior of the device and from the interior of the device to the exterior of the device after the device is in a closed state, the method comprising: generating a noise signal in the interior of the device to minimize reception of at least one of an audio signal or an electromagnetic signal from an exterior of the device to an interior of the device after the device is in a closed state;generating a noise signal in the interior of the device to minimize transmission of at least one of an audio signal or an electromagnetic signal from an interior of the device to an exterior of the device after the device is in a closed state; andsupplying power to an electronic device in an interior of the device during a period when the device is in a closed state. 2. The method of claim 1, further comprising: supplying power to the electronic device in an interior of the device during a period when the device is in an open state. 3. The method of claim 1, further comprising: generating an alarm signal indicating that the device is in an open state during a period when the device is in an open state. 4. The method of claim 3, wherein the generation of the alarm signal occurs after the device has been in an open state for a predetermined period of time. 5. A method of operation of an anti-eavesdropping device, the anti-eavesdropping device being constructed of materials to minimize transmission of electromagnetic and/or audio signals from an exterior of the device to an interior of the device and from the interior of the device to the exterior of the device after the device is in a closed state, the method comprising: generating a noise signal in the interior of the device to minimize reception of at least one of an audio signal or an electromagnetic signal from an exterior of the device to an interior of the device after the device is in a closed state;supplying power to a portable electronic device in an interior of the device during a period when the device is in a closed state; andgenerating an alarm signal indicating that the device is in an open state during a period when the device is in an open state. 6. The method of claim 5, further comprising: supplying power to the portable electronic device in an interior of the device during a period when the device is in an open state. 7. The method of claim 5, wherein the generation of the alarm signal occurs after the device has been in an open state for a predetermined period of time. 8. A method of operation of an anti-eavesdropping device, the anti-eavesdropping device being constructed of materials to minimize transmission of electromagnetic and/or audio signals from an exterior of the device to an interior of the device and from the interior of the device to the exterior of the device after the device is in a closed state, the method comprising: transitioning the device from an open state to a closed state to minimize transmission of at least one of an electromagnetic signal or an audio signal from an interior of the device to an exterior of the device after the device is in a closed state;minimizing, based on the construction of the device, reception of at least one of an electromagnetic signal or an audio signal from an exterior of the device to an interior of the device after the device is in a closed state; andsupplying power to an electronic device in an interior of the device during a period when the device is in a closed state. 9. The method of claim 8, further comprising: supplying power to the electronic device in an interior of the device during a period when the device is in an open state. 10. The method of claim 8, further comprising: generating an alarm signal indicating that the device is in an open state during a period when the device is in an open state. 11. The method of claim 10, wherein the generation of the alarm signal occurs after the device has been in an open state for a predetermined period of time.
