摘要： Embodiments of the invention involve using biometric templates to wirelessly authenticate individuals. In one embodiment, a mobile device may generate a first biometric template and a first public value from a first biometric sample of a user and generate a first cryptographic key by passing the first biometric template to a fuzzy extractors generate function. An access device may generate a second biometric template from a second biometric sample of the user, generate a second secret cryptographic key by passing the second biometric template and the first public value to the fuzzy extractors reproduce function, encrypt the second biometric template with the second secret cryptographic key, and broadcast the encrypted template to a plurality of nearby mobile devices including the mobile device. If the mobile device is able to decrypt the encrypted template with the first cryptographic key, the access device can associate the user with the mobile device.

摘要： Embodiments identify heap-hoarding stack traces to optimize memory efficiency. Some embodiments can determine a length of time when heap usage by processes exceeds a threshold. Some embodiments may then determine heap information of the processes for the length of time, where the heap information comprise heap usage information for each interval in the length of time. Next, some embodiments can determine thread information of the one or more processes for the length of time, wherein determining the thread information comprises determining classes of threads and wherein the thread information comprises, for each of the classes of threads, thread intensity information for each of the intervals. Some embodiments may then correlate the heap information with the thread information to identify code that correspond to the heap usage exceeding the threshold. Some embodiments may then initiate actions associated with the code.

摘要： A methodology for processing authorization request messages based on proximate wireless networks is disclosed. In particular, a computer may receive, from an access device or a communication device, an authorization request message in a transaction. The computer may then obtain network data based on a set of wireless networks that are proximate to the access device or the communication device interacting with the access device during the transaction. Next, the computer may determine a difference between the network data and previous network data, wherein the previous network data is based on one or more previous sets of wireless networks that were proximate to the access device or the communication device during one or more previous transactions. Responsive to determining that the difference exceeds threshold, the computer may initiate one or more actions associated with the transaction.

摘要： Embodiments of the invention are directed to techniques for detecting anomalous values in data streams using forecasting models. In some embodiments, a computer can receive a value of a data stream comprising a plurality of data values, where the received value corresponds to a time interval and previously received values each correspond to a previous time interval. Models can be selected based on the time interval, where each of the models has a different periodicity. For each of the selected models, the computer may generate a score by generating a prediction value based on the model and generating the score based on the prediction value and the received value. A final score can then be generated based on the scores. Next, a score threshold can be generated. If the final score exceeds the score threshold, the computer may generate a notification that indicates that the data value is an anomaly.

摘要： In a system for verifying transactions, when a user with a portable communication device nears a resource provider location, the portable communication device provides an indication to a transaction processing system of its proximity to the location. The portable communication device then provides a universally unique identifier (UUID) of a base station of the resource provider to the transaction processing system, which generates a hash using the UUID and a primary account number (PAN) of a portable transaction device that is associated with the portable communication device. When the user conducts a transaction with the portable transaction device at the provider, the provider generates a separate hash from the UUID and the PAN and sends the hash to the transaction processing system, A match between the hashes is taken into account as a positive indicator that the transaction is not fraudulent and the resource provider is complying with the system.

摘要： Certain techniques are disclosed for sequentially analyzing a series of thread dump samples to estimate the intensity statistics of newly classified stack segments of stack frames. Embodiments can detect a branch point along one or more linearly connected stack frames of a stack segment, where the stack segment is associated with a filter state. Upon detecting the branch point along the one or more linearly connected stack frames of the stack segment, some embodiments can split the stack segment into a plurality of new stack segments that each include a subset of the stack frames, where the plurality of new stack segments are referenced by the stack segment. Embodiments can then initialize a filter state for each of the new stack segments based at least in part on the filter state of the stack segment.

摘要： Embodiments provide a thread classification method that represents stack traces in a compact form using classification signatures. Some embodiments can receive a stack trace that includes a sequence of stack frames. Some embodiments may generate, based on the sequence of stack frames, a trace signature that represents the set. Some embodiments may receive one or more subsequent stack traces. For each of the one or more subsequent stack traces, some embodiments may determine whether a subsequent trace signature has been generated to represent the sequence of stack frames included within the subsequent stack trace. If not, some embodiments may generate, based on the trace signature and other subsequent trace signatures that were generated based on the trace signature, the subsequent trace signature to represent the subsequent sequence of stack frames.
