摘要:
Systems, methods, and media for analyzing fraud patterns and creating fraud behavioral models are provided herein. In some embodiments, methods for analyzing call data associated with fraudsters may include executing instructions stored in memory to compare the call data to a corpus of fraud data to determine one or more unique fraudsters associated with the call data, associate the call data with one or more unique fraudsters based upon the comparison, generate one or more voiceprints for each of the one or more identified unique fraudsters from the call data, and store the one or more voiceprints in a database.

Disclosed is a method for enrolling a voiceprint in a fraudster database, the method comprising: a) defining a fraud model comprising at least one hypothesis indicative of a fraudulent transaction; b) processing audio data based on the fraud model to identify at least one suspect voiceprint in the audio data suspected of belonging to a fraudster; and c) enrolling the at least one suspect voiceprint in the fraudster database.

Disclosed is method for screening an audio for fraud detection, the method comprising: providing a User Interface (UI) control capable of: a) receiving an audio; b) comparing the audio with a list of fraud audios; c) assigning a risk score to the audio based on the comparison with a potentially matching fraud audio of the list of fraud audios; and d) displaying an audio interface on a display screen, wherein the audio interface is capable of playing the audio along with the potentially matching fraud audio, and wherein the display screen further displays metadata for each of the audio and the potentially matching fraud audio thereon, wherein the metadata includes location and incident data of each of the audio and the potentially matching fraud audio.

Disclosed is a method for generating a fraud risk score representing a fraud risk associated with an individual, the method comprising: a) determining a telephony channel risk score from at least one of audio channel data and non-audio channel data of the individual; and b) generating the fraud risk score based on at least one of the telephony channel risk score, the audio channel data, and the non-audio channel data.

Conjugated dienes and alpha-olefins, such as butadiene and propylene, are copolymerized by a new catalyst system which gives copolymers containing a high proportion of the alpha-olefin with accompanying desired properties. This catalyst system comprises: (1) A titanium or vanadium halide, preferably chloride, (2) an aluminum hydrocarbon compound which also has Cl, Br or H attached to the Al atom and preferably the hydrocarbon group or groups are alkyl groups which have 1-8 carbon atoms in each of said alkyl groups and (3) CS.sub.2. The copolymers produced by this process have molecular weights in the range of 100,000-5,000,000; referably 250,000-500,000, and other desirable properties.

According to one aspect of the invention there is provided a method, comprising collecting voiceprints of callers; identifying which of the collected voiceprints are associated with fraud; and generating a whitelist comprising voiceprints corresponding to the collected voiceprints not identified as associated with fraud.

Systems, methods, and media for generating fused risk scores for determining fraud in call data are provided herein. Some exemplary methods include generating a fused risk score used to determine fraud from call data by generating a fused risk score for a leg of call data, via a fuser module of an analysis system, the fused risk score being generated by fusing together two or more uniquely calculated fraud risk scores, each of the uniquely calculated fraud risk scores being generated by a sub-module of the analysis system; and storing the fused risk score in a storage device that is communicatively couplable with the fuser module.
