Digital Forensics, Computer Forensics, Mobile Forensics

Digital forensics is commonly used in both criminal law and private investigation. Traditionally it has been associated with criminal law, where evidence is collected to support or oppose a hypothesis before the courts. As with other areas of forensics this is often as part of a wider investigation spanning a number of disciplines. In some cases the collected evidence is used as a form of intelligence gathering, used for other purposes than court proceedings (for example to locate, identify or halt other crimes). As a result intelligence gathering is sometimes held to a less strict forensic standard.

In civil litigation or corporate matters digital forensics forms part of the electronic discovery (or eDiscovery) process. Forensic procedures are similar to those used in criminal investigations, often with different legal requirements and limitations. Outside of the courts digital forensics can form a part of internal corporate investigations.

At ACP, we have experienced digital forensics examiner with expertise in corporate fraud, labor disputes, domestic relations, child pornography, the Adam Walsh Act, electronic discovery, the work product doctrine, and the attorney client privilege. Our expert is available to serve not only as a digital forensics examiner, but also as an expert witness and court-appointed third-party neutral. Reference available upon request.

Smartphones & Tablets Forensics

Photos & Graphics, Videos, Text Messages, Address book, Call records

Mobile devices can be used to save several types of personal information such as contacts, photos, calendars and notes, SMS and MMS messages. Smartphones may additionally contain video, email, web browsing information, location information, and social networking messages and contacts often intentionally, and sometimes unintentionally. This holds true for almost all mobile devices, such as PDAs, SmartPhones and Tablets, e.g. iPhones, iPads. Our forensic experts specialize in the forensic retrieval of data from cell phones and other electronic devices in a manner that preserves the evidence under forensically acceptable conditions, ensuring that it is court-admissible.

Some data may be retrieved and examined during a mobile device forensic investigation, even after being deleted such as Photos & Graphics, Videos, Text Messages, Address book, Call records, notes.

A cell phone forensic investigation includes possible full data retrieval dependent upon the cell phone, PDA, or tablet model. Our mobile device forensic investigator will conduct a thorough examination of the data found on the device's SIM/USIM and any optional internal/external memories
