Patent ID: 8613087

Claim:
A computing system comprising: a data processing device configured to exchange communication data with entities outside the computing system and configured to process the communication data; and a security integrated circuit (IC) configured to monitor the communication data, wherein the security IC includes a non-volatile memory configured to store a plurality of strings, and a comparing block configured to judge whether the communication data coincides with at least one of the plurality of strings; wherein the comparing block is configured to generate a disable signal according to whether the communication data is identical to at least one of the plurality of strings, wherein the security IC is configured to send an interrupt signal to the data processing device according to the disable signal, wherein the data processing device is configured to provide the security IC with a control signal in response to the interrupt signal so that the security IC filters the communication data, and make inquiries about an interruption of the communication data to a user in response to the interrupt signal, and configured to send the control signal according to an input of the user.
