Our services
We are subject matter experts in the following areas
Biometrics
Experts in fingerprint analysis. We challenge flawed forensic methods, and improve identification accuracy.
Cell Phone and Tower Tracking
Our custom software detects NELOS, RTT and PCMD cell phone location errors that change trial outcomes.
Breach Avoidance
We identify vulnerabilities to prevent breaches and unauthorized data access.
We have addressed the United Nations Security Council Counter-Terrorism Committee concerning biometrics, cybersecurity and geolocation.
About us
We are the only cell phone and tower expert witnesses to have won all: Innocence, Habeas, Daubert, Driving Test, Primary Residency Tax, the Exclusion of Call Detail Records, and the Exclusion of Cell Phone Location Records.
We are early Apollo 11 analysts and programmers who taught college mathematics and consulted at both AT&T and Bell Labs. As former Sony and IBM business partners, we have designed and programmed products that have been successfully sold worldwide.
Our 10,000 plus hours of AT&T and Verizon telecommunications knowledge programming and training is the key to our numerous courtroom wins.
We have programmed telecommunications switches used for cell towers and landlines. We understand the respective strengths and weaknesses of phone extraction software including Cellebrite, MSAB, GrayKey and others. Their capabilities combined with our programming skills can open the door to reviewing case related hidden and deleted cell phone, cloud and computer information.
Our software finds a large percentage of undetected NELOS, RTT, and PCMD cell phone location errors. The finding of these errors invalidates their use, resulting in favorable trials and habeas proceedings.
We addressed the National Academy of Sciences and identified FFT conversion problems associated with both AFIS and manual fingerprint matching. We vote on biometric standards at the US Department of Commerce National Institute of Standards and Technology (NIST). The United States Department of Justice (DOJ) has the following fingerprint articles on their website that we co-authored with U.C. Davis Professor Emeritus Edward J. Imwinkelried:
