Technology marches on

with one comment

Technology doesn’t stand still in the Homeland Security field!  Several recent developments—from the fields of information technology, biometric engineering, and social psychology—are worth a closer look.  These are all available on the Homeland Security Newswire, which offers current reporting on technological developments in the security profession.

Frankenmalware

Many of us have probably felt our computers know more than we do at times, but we can still change and adapt, while they get obsolete, right?  Right… but there are now indications that snippets of programmed code have recombined in ways their creators never planned.  Unfortunately, these bits of code are malwareviruses and worms.  Viruses have been seen to accidentally make use of worms, propagating themselves more effectively in a “malware sandwich” or “Frankenmalware.”  According to a post at the Malware City blog, this is how it can happen:

Now, another “practice” has silently emerged: the file infector that accidentally parasites another e-threat. A virus infects executable files; and a worm is an executable file. If the virus reaches a PC already compromised by a worm, the virus will infect the exe files on that PC – including the worm. When the worm spreads, it will carry the virus with it. Although this happens unintentionally, the combined features from both pieces of malware will inflict a lot more damage than the creators of either piece of malware intended.

It may also be that in some cases, cleaning by antivirus programs may help altered malware escape detection.  Read more at http://www.malwarecity.com/blog/virus-infects-worm-by-mistake-1246.html/

Handy fingerprints?

Biometric systems are increasingly common.  However, the need for stationary equipment to read and process prints has limited its utility in some fields.  Now, researchers at Neurotechnology have developed an application which allows smartphones and other mobile devices to run scans almost anywhere.  The mobile products contain the same algorithms as the company’s PC-based versions of their products, which meet AFIS-level recognition standards.  Homeland Security Newswire explains that these devices can handle fingerprint or facial recognition quickly, with iris and voice capabilities on the way:

The company says that VeriFinger Embedded and VeriLook Embedded can process fingerprint or face images in less than one second using a device with a 1GHz or better processor. The first available release of the new MegaMatcher Embedded product includes VeriFinger and VeriLook fingerprint and face biometric algorithms, and versions incorporating iris and voice biometrics are planned in the coming months.

Happy, sad, silly, mad

Remember learning about smiles and frowns in preschool?  Actually, sorting out human facial expressions isn’t so simple, but researchers at King’s College London have isolated the characteristics of a face displaying anxiety.  Their research, published recently in in the Journal of Personality and Social Psychology, shows that the emotion we call anxiety is expressed by an environmental scanning look that appears to aid risk assessment:

The characteristics of the facial expression for anxiety comprised darting eyes and head swivels that echoed the risk assessment behavior of anxious rodents. These results suggest that the anxious facial expression in humans serves to increase information gathering and knowledge of the potentially threatening environment through expanding the individual’s visual and auditory fields. Therefore the anxious facial expression appears to have both functional and social components — its characteristics help assess our surrounding environment, and communicate to others our emotional state.

The lead author of the study, Dr. Adam Perkins, noted that the findings could help security personnel identify individuals engaged in wrongdoing by means of their anxious, risk assessing facial expression, as well as helping mental health professionals assess their patients.
