  • Method and system for validating a vulnerability submitted by a tester in a crowdsourcing environment

    Issued US 10,291,643

    A method for validating a vulnerability submitted by a tester in a crowdsourcing environment. The method comprises identifying at least one vulnerability within at least one computer resource and receiving vulnerability data corresponding to the at least one vulnerability. The method further comprises pre-processing the vulnerability data to generate structured data and generating a replica of the vulnerability using the structured data and at least one validator. Further, the method comprises…

    A method for validating a vulnerability submitted by a tester in a crowdsourcing environment. The method comprises identifying at least one vulnerability within at least one computer resource and receiving vulnerability data corresponding to the at least one vulnerability. The method further comprises pre-processing the vulnerability data to generate structured data and generating a replica of the vulnerability using the structured data and at least one validator. Further, the method comprises calculating a confidence score of the vulnerability using the replica of the vulnerability and a result of the at least one validator. The method executes at least one validating instruction based on the confidence score of the vulnerability.

  • Method and Apparatus for Identifying a Drift in a Quantized Signal

    Issued US 7444268

    One embodiment of the present invention provides a system that identifies a drift in a signal in a computer system. During operation, the system receives a sequence of quantized signal values of the signal. Next, the system generates a statistical distribution based on the sequence of quantized signal values, wherein the statistical distribution is generated using a set of counters, wherein each counter keeps track of the number of occurrences of an associated quantized signal value. The system…

    One embodiment of the present invention provides a system that identifies a drift in a signal in a computer system. During operation, the system receives a sequence of quantized signal values of the signal. Next, the system generates a statistical distribution based on the sequence of quantized signal values, wherein the statistical distribution is generated using a set of counters, wherein each counter keeps track of the number of occurrences of an associated quantized signal value. The system periodically adjusts the counters by multiplying each counter by a compression factor if the system determines the sum of the set of counters is greater than or equal to a threshold. The system identifies the drift in the signal by comparing the statistical distribution with a reference distribution of the quantized signal values, wherein the reference distribution is associated with normal operation of the computer system.
