We study the “anti-theft” mechanisms available to consumers to thwart unauthorised access to personal data on stolen Android smartphones. With millions of devices stolen in the USA in 2013 alone, such attacks are a serious and growing problem. The main mitigation against unauthorised data access on stolen devices is provided by “anti-theft” apps; that is, with “remote wipe” and “remote lock” fu...

Dermal exposure to drilling fluids and crude oil is an exposure route of concern. However, there have been no published studies describing sampling methods or reporting dermal exposure measurements. We describe a study that aimed to evaluate a wipe sampling method to assess dermal exposure to an oil-based drilling fluid and crude oil, as well as to investigate the feasibility of using an interc...

This experimental study suggests an alternative method of data deletion which can be considered secure up to an acceptable level for most purposes while maintaining anti-forensics characteristics. It is a quick and “dirty” solution to remove data from a storage medium while achieving to confuse the investigator about the contents of the i.e. the hard disk. More specifically, working upon the fi...

In this paper, the data wipe-off (DWO) algorithm is incorporated into vector tracking loop of Global Positioning System (GPS) receiver for improving signal performance. The navigation data, which contains information that necessary to perform computations, are binary phase-shift keying (BPSK) modulated onto GPS carrier phase with bit duration 20 ms (i.e., 50 bits per second). To continuously tr...

Methamphetamine (meth) from meth syntheses or habitual meth smoking deposited on household surfaces poses human health hazards. The U.S. State Departments of Health require decontamination of sites where meth was synthesized (meth labs) before they are sold. National Institute for Occupational Safety and Health (NIOSH) methods for meth analysis require wipe sampling, extraction, clean-up, solve...

High-efficiency particulate air (HEPA) filtered vacuum cleaners are recommended by the U.S. Department of Housing and Urban Development for cleaning lead-contaminated house dust. We performed a randomized field study to determine whether a conventional (non-HEPA) vacuum cleaner could achieve cleaning results comparable with those of a HEPA vacuum cleaner. We compared the lead loading reductions...

PURPOSE Lens case hygiene is important for safe contact lens wear. However, there are no evidence-based data to suggest optimum hygiene regimens. This in vitro study aimed to evaluate and compare the effectiveness of manufacturers' guidelines and several other regimens in removing biofilm using various types of contact lens cases and disinfecting agents. METHODS Biofilms of Staphylococcus aur...
