Reporters obtained the following quote from the background information supplied by the inventors: "Senior executives and officials constantly strive to keep sensitive, confidential intellectual property and trade secrets protected. During personal conferences involving the discussion of sensitive matters, for example matters relating to strategic approaches, advertising, new products or the like, for example those typically held in offices and elsewhere, the confidentiality of communications, such as oral communications with others must be maintained. However, at the same time, staying in contact with one's coworkers is, more than ever, typically being done by cellular or mobile wireless devices. These individuals thus need to keep their devices connected to the network and be able to recognize and respond to certain calls and messages even when otherwise having sensitive and confidential discussions with others. However, such devices present a threat to security, whether through hacking not authorized by the owner of the device, or through surreptitious use of the device by its owner. More particularly, the technology exists today for the unauthorized conversion of another's smartphone or other handheld device into a 'bug' enabling the hacker to listen in on a conversation being carried on in the proximity of the hacked device.
"Typically, such hacking involves enabling the microphone in a smartphone and establishing a connection between the smartphone and a recording device being operated by the hacker. In this manner, the hacker can make a recording of the conversation available to, for example, competitors, hostile government officials, or other industrial, political or military espionage services.
"Today more and more devices are capable of multiple functions and a growing number of devices are capable of being manipulated remotely by using the microphone in the device as a remote listening device. In addition to such conversion of the device's built-in microphone to allow room sounds to be picked up and transmitted to a remote location, the possibility also exists for the smartphone's built-in video camera to be converted to perform a military, political or industrial espionage function."
In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventors' summary information for this patent application: "In one embodiment, the present invention is directed to an enclosure which produces a unique shaped and modified white or pink noise tailored to effectively mask voice conversations, to prevent the cellular or mobile wireless devices within it from picking up sounds from the surrounding area. The inventive mobile phone/PDA security sound masking enclosure provides a countermeasure against the vulnerability of subjecting confidential and private conversations to being picked up and recorded by cellular or mobile wireless devices, and yet allows for alerting of incoming calls and visual identification of caller ID to allow the conversation to be interrupted and the required phone call or message responded to. Several cellular or mobile wireless devices can be placed within the enclosure simultaneously as well as potentially vulnerable devices that have or may have electronics within such as watches, pens, recorders, thumb drives, etc.
"Every box has an acoustic noise generator with a unique audio profile calculated to make filtering or neutralization of the jamming signal difficult or substantially impossible.
"As normal human speech typically falls between 55 and 60 decibels, the enclosure will generate up to 90 decibels of unique noise within the enclosure. As the frequency of the human voice typically falls between 250 Hz and 3.5 KHz, the noise source within the enclosure will emit audio between frequencies of 200 Hz and 4 KHz, utilizing white or pink noise and other sounds, or combining white and pink noise to create an overlapping set of random signals and effectively mingling the white and pink noise sounds with all their frequencies and amplitudes in that bandwidth. The noise emitted will thus vary volume levels and output a non-recreatable blend of sounds that covers a large spectrum of frequencies and effectively masks the voices in the room. This active noise masking coupled with the passive reduction of voices in the room provided by the sealed enclosure, effectively drops the voice level and covers it with noise that is unintelligible and difficult to process to remove the noise and enhance the audio.
"It is an object of the present invention to provide a new and improved security box for cellular or mobile wireless devices that will prevent such devices from picking up or recording conversations taking place outside of the box.
"It is an object of the present invention to provide a new and improved security box for cellular or mobile wireless devices that will allow such devices to receive incoming calls while isolating them from local conversations and alert owners of the device that the device is being called.
"It is an object of the present invention to provide a new and improved security box for cellular or mobile wireless devices to be easily accessed should the devices require attention while isolated.
"These and other objects and advantages of the present invention will be fully apparent from the following description, when taken in connection with the annexed drawings.
