IKAR Lab is comprised of advanced and time tested technologies and algorithms which are already in use at over 3. IKAR Lab is available as a software and component hardware only solution or a complete turn key solution including the workstation hardware, auxiliary equipment and training courses. Voice Database. Nowadays, law enforcement agencies LEAs tend to keep all forensic trace evidence in regularly updated and well structured databases, a good practice that allows for quick suspect identification in instances of repeat crime. While fingerprint, ballistic and facial databases have already been widely adopted by LEAs, voice databases are only starting to find their use. Voice. Grid Local provides essential forensic database management and voice identification functionality. Any voice recording that forms part of an investigation is added to the database with an accompanying case description, along with information and photos pertaining to the speaker. Voice matching in Voice. Grid Local is carried out using proprietary processing, feature extraction and voice identification methods. Voice. Grid Local performs a biometric search of probable speakers across the entire voice database or in a desired section. Unidentified voice recordings can always be compared with the samples available in the database. Client server architecture of the product allows for remote access to the database. Access policy is highly secured and flexible. Specs. Voice Biometric Algorithms. Number of identification methods. Form of voice biometric search results.

Tracker significantly enhances SIS II functionality, extending its capability in revealing modified, edited or doctored audio. FeaturesThe advent of digital audio made it far easier to tamper with recorded evidence. But it also gave investigators a host of new and powerful tools. Improvements in forensic audio software have given the field a big boost. LGC offers a full service digital forensic investigation service to the criminal justice system, solicitors and corporate clients. Allen Stuart Allen, forensic audio expert, for example, used a software package called Edi. Tracker 2. 0 to dissect his doctored recording. First he played the audio file for the audience and displayed its spectrogram on a projection screen. Then he punched a key on his laptop. Within seconds, Edi. Tracker had scanned the file and flagged a bunch of feature discontinuities unexpected bumps in frequency and amplitude, miniscule gaps and other unusual events. Theyre undetectable to the naked ear, but could indicate tampering. Wired Magazine, Audio Forensics Experts Reveal Some Secrets by Alexander Gelfand. Calculation of a recorders parameters. Each analog recorder has its own characteristics such as frequency response, total harmonic distortions, detonation, amplitude modulation, and speed. Edi. Tracker automatically assesses these characteristics using a test signal. Finding a mismatch between the recorders parameters and characteristics of a signal that was allegedly recorded with a given unit can be an indication of tampering. Game Call Of Duty 6 Modern Warfare 2 Full'>Game Call Of Duty 6 Modern Warfare 2 Full. Finding the traces of previous digital processing. Digital processing of analog signals requires a specific sample rate. During the digitizing process of an analog signal, a phenomenon called aliasing occurs. To avoid this phenomenon, the vast majority of analog to digital and digital to analog converters use anti aliasing filters. Edi. Tracker automatically searches for traces of the filter, which may be reminiscent of analog nature of the original audio or previous digitizing at a lower sampling rate. Finding the traces of tampering by the harmonics phase shift. Edi. Tracker automatically scans the audio for technical narrow band signals which normally come from an electrical network ENF, batteries, nearby electrical appliances etc and estimates their phase continuity. Unjustified phase break may be interpreted as a possible editing point and should be subject to further auditory and instrumental analysis. Background noise scanning. Background scanning procedure is the detection of the dramatic change in the spectrum unnoticeable on the waveform related to possible audio editing. Edi. Tracker automatically scans the integrity of background noises marking the abrupt change of noise level. Auditory analysis. Edi. Tracker provides an access to the step by step instructions for the auditory linguistic analysis and to the extended list of indicators of a recording authenticity breaches making it possible to create a detailed list of linguistic features of tampering and further use them in a text report. Amped FIVE Forensic Video and Image Enhancement. Maintaining the original evidence integrity is a key element in the design of Amped FIVE. In the law enforcement arena, courts, judges, prosecutors, and defense attorneys can sense the weakness of evidence and exclude it if there is any manipulation that has been done. The current judicial trend in admission of digital evidence shows that undocumented or modified files have a strong chance of being excluded. If this is the key evidence in a case, the case is likely to be lost. With Amped FIVE, our core philosophy in designing the product is that everything is done by simply applying a filter. This means that no rendering, modifying, altering or disturbing original evidence is done. Whether you are loading a video, exporting a sequence, applying some denoising, selecting frames, taking measurements and so on. This concept of filtering allows for very fast, elegant, and predictable workflow. For each step in the process, every filter takes as input the image or video generated by the previous filter and, after the processing, passes the result to their output filter if any. You can even modify a filter and see the real time output effects on another one in this way you can see how modifying some values on a previous filter will modify the final result. This is very effective especially for complex problems and long chains of filters. Trial and error is often the most common scientific method that is applied in forensic analysis. Experimenting with different filters and settings is done to find the right filter group, settings, or combination of steps to correct unique problems. With most other forensic image processing software, this is a very long process that often must be restarted if one filter has to be changed or results are not optimal then restarted again should the results of the second or third or fourth, etc result prove to be less than ideal. We have designed the architecture of Amped FIVE with this in mind. Reviewing and modifying any step of the processing is as quick and easy and as simple as replacing, deleting or moving filters anywhere in the chain. In this way Amped FIVE guarantees speed, effectiveness and scientific rigor.
