The mobile application security system and method in accordance with the invention increases the overall level of security in using a mobile application. In a preferred embodiment, the system may use a peer-to-peer architecture wherein each host of a mobile application is a node of the peer-to-peer network. In operation, when a mobile application jumps between hosts (nodes), information about the mobile application is generated and sent to a central security enforcement node so that the central security enforcement node may perform various security checks. The security checks ensure that the security of the mobile application is not compromised.

A method and system is described to improve the reproduction of sound of an acoustic musical instrument. According to one embodiment, a first microphone is placed at a proximate location to the musical instrument to pick up the sound of the musical instrument. The sound as picked up by the first microphone is compared to a reference sound of the instrument (e.g., the sound of the instrument as perceived at a normal listening position). Based on this comparison, a tailor-made equalizer is designed to compensate for the differences between the sounds as picked up by the first microphone and the reference sounds of the musical instrument. Accordingly, using the tailor-made equalizer allows the reproduction of sound from the first microphone to have a quality similar to that of the reference sound of the musical instrument. In an implementation of the above system, a filter arrangement is provided having a low-pass and a high-pass filter that allows separate control of the frequency and / or gain for each filter.

The mobile application security system and method in accordance with the invention increases the overall level of security in using a mobile application. In a preferred embodiment, the system may use a client / server architecture wherein each host of a mobile application is treated as a client and a central computer is treated as the server. In operation, any time that a mobile application is going to jump between hosts, it must first pass through the central computer so that the central computer may perform various security checks. The security checks ensure that the security of the mobile application is not compromised and overcomes the above problems with typical mobile application systems.
