Smart Dust: Communication Systems and the Future World

When you first hear the word, Smart Dust, you might think of a fairy tale or something involving magic. Smart Dust actually describes microelectromechanical (MEMS) devices that include sensors, computational ability, and more. They can be as tiny as dust particles and can spread throughout buildings and into the atmosphere to collect and monitor data. Smart Dust isn’t actually a new concept and has been around since the beginning of the 1990s when it was invented out of a prolonged research and study project convened by the United States Defense Advanced Research Projects Agency and the Research And Development Corporation (RAND).

Smart Dust can be employed in most industries from agriculture to the medical industry and communication. To be precise, the entire world could be measured by means of these omnipresent sensors. The Machine-to-Machine accessible smart dust is made of motes, which are tiny sensors capable of performing a variety of functions. Smart dust is activated by MEMS and brings progression in digital circuitry and wireless communication. Every node used in the sensor network comprises three subsystems including the mechanisms that sense the environment, the processing means to perform local computations, and the communication subsystem responsible for message exchanging based on adjoining sensor nodes.


Smart Dust Possibilities

A key implementer of smart dust, UC Berkeley Professor Kris Pister, stated in a press conference that,

“integrated with superior computing efficiency, wireless radios, and sensing tech, smart dust will be quite a comprehensive solution to study the real time data concerning people, industries, cities as well as natural environment.”


The great scopes of these sensors include:

l The processing power, energy, and networking of a volume of sensors offers a more reliable, consistent, and robust sensor net covering a wider segment. The sensors are backed by a vibration mechanism that can be used to identify problems in machineries installed at oil refineries.

l The nodes work together and lead to correct sensing. The two most vital operations in any sensor network are basically data broadcasting or spread of voice, queries, and data throughout the network.

l Sensing nodes can be employed in different industries including military, chemical processing, health, disaster relief, and broadcasting.

l Smart sensing technology enhances the quality and efficiency of communications, embedded processing, virtualization, and network enabled tools apart from the software infrastructure.

l The modernization of mobile terminals and information systems and the incorporation of a wide range of sensing-intelligent instruments is supposed to bring superiority to sensory inputs and enhance industry standards.

l With the development of 3G technologies over the globe, M2M applications are predicted to bring higher data speeds.

l With the integration of advanced mobile internet instruments like the iPad, these sensory inputs are likely to drive inclination from the world of 3 and 4G mechanisms.

l While the transportation trade is greatly influenced by real time navigation and require high-level bandwidth, the smart systems will bring advanced connectivity.


With smart dust, there are many possibilities and multinational companies are getting in on it. For example, HP’s goal is to deploy over a trillion smart dust sensors across the planet to generate a Central Nervous System of the Earth and is working with Royal Dutch Shell to install a million monitors to aid in oil exploration. These tiny devices would evaluate the health of ecosystems, foresee the possibility of earthquakes effectively, review traffic patterns, and observe energy use. However, there are still limitations and challenges that come along with smart dust technology.


Are There any Computer Forensic Experts in Tampa Florida

Many companies today need to keep track of what employees are doing on their computers especially during company working hours. Other times they need to carry out an investigation that requires a report about the usage of the computers and the internet. That is when a computer forensic is needed.

Computer forensic experts have both investigative skills as well as the IT skills required to perform a forensic check on digital machines. It is very important that you find the right computer forensic experts. If you find yourself asking, “Are there any computer forensic experts in Tampa Florida?” Well, the answer is yes but here are a few pointers to pick out the genuine ones from the fakes, since there are many who may not even be able to help in testifying in court.

Certification: The experts always have certification. Digital Computer Forensic experts have been trained to carry out this service and the best way to prove training without the actual practice is the presentation of certification both from wherever they received their training as well as a certification body that allows them to practice and give expert opinions in court.

Investigative ability: As a forensic expert, there has to be more than just the skill to collect the data from the machines. Forensic work involves carrying out systematic collection of data and then being able to study and interpret the data collected so that conclusions can be made. The investigative ability comes in handy when you need a witness in court who can provide substantial evidence in a case.

Experience: Part of being an expert is having experience in a particular field. In the field of computer forensics, experience is very important. You should not just be asking if there are any computer forensic experts in Tampa Florida but if there are experienced forensic experts. This does not only apply to the company but the individual as well who is tasked with providing the forensic assistance. It is good to have a few questions to see if they are experienced enough.

In Tampa Florida you can find computer forensic experts to help you with: Formulating a preservation request, preservation compliance, investigation on theft of intellectual property, finding out if employees are abusing company property and resources, investigate sexual harassment complaints, website and social media investigations, sexual harassment complaints, missing children, fraud and so many more.

There is a lot of information that can be retrieved during forensic investigation on computer and there are quite a few companies that can do this in Tampa Florida.



What Is a Forensic Write Blocker?

What Is a Forensic Write Blocker?

Forensic write blockers are used when trying to attain information from a drive without damaging the data on that drive. They act like a filter that will allow data to be read but blocks write commands from getting through as this will put information on the drive at risk.

Forensic write blockers can either block all write commands from getting through or they can be designed to filter certain write commands. The blocker can be fed with a list of commands that should be blocked so they will let every other command go through except for those that are contained in the list. Alternatively, write blockers can be used to slow down the speed at which data is read. Some drives have a kind of protection which prevents reading at high speed. The blocker is used to slow down the speed of the disks and that will make them easier to read. This is important when carrying out forensics on certain machines.

Forensic write blockers can be used for hardware or software. There are hardware writers and software writers which both do the same job but vary in where they are installed.

Hardware write blockers are installed with a chip that contains software to do the blocking while the software write blocker is installed on the workstation.


In essence, when it comes to forensic investigations, write blockers are essential in preserving the data or information on a disk which is the evidence that is being collected. Many times operating systems tend to write to any hard drive that is connected to it and this can very easily alter important facts such as time when a document may have been accessed or altered. Viruses and Malware to can cause alteration to data but when you use the write blocker, the commands that would have accompanied the access of this information is blocked leaving the information in its original state.

In court, lawyers can argue that information may have been altered during an investigation. By attaching a forensic write blocker, the forensic experts ensure that they preserve the device and its data in a state that will show it has not been contaminated so the evidence provided after forensic can be trusted.

In general, the forensic write blocker will do the following

– It will block any changes from being made to the drive thus prevent contamination of evidence

– Make any information on the drive readable and accessible but as read only

– Will allow operations of a drive that is not protected.

How Law Enforcement Uses Computer Forensics

Computer forensics have been used even more frequently in today’s field of computer science and law enforcement to be able to investigate crime. For any of the digitial evidence to be accepted within the court, the investigators have to follow all of the legal procedures when they are analyzing any of the data from the computer systems when they recover it. However, there are many laws that were written before the time period when computers existed, and they cannot appropriately assess all of the techniques that are normally used within computer searches. If the law does not have the ability to continuously keep up the pace with the advancements in the technologies, then it could limit the use of computer forensic evidence in the courts, which is devastating to specific cases. There are many individuals who are privacy advocates who believe that computer searches may be a breach of the suspect’s basic human rights. However, as this type of technology grows, it may be a disadvantage in that it could be abused to help criminals hide their illegal actions. The role that technology plays in the forensics of computers, may not reach the level it needs, so that it can avoid malicious intentions and legal boundaries.

The area of computer forensics has been incredibly indispensable in the convictions of many known criminals. These types of criminals include terrorists, murderers, and sexual predators. It is already known to society that terrorists can use the internet to recruit and create a larger group of terrorists to join them, and sexual predators have the ability to more easily stalk their potential victims online. There is a downfall that many of these criminals look over, and that is that most of these criminals fail to properly cover their criminal action tracks. Many of them fail to realize that when they delete something from their computer, that it does not completely erase the information from their hard drive or their computer files. Therefore, this helps investigators to track down their criminal activities on their computers. However, there have been many cases in which the individuals has claimed that for the investigators to go through their cell phones and computers, is the same thing as going through their personal bag or their private home. Therefore, they are claiming that it goes against their basic human rights of the Constitution. This means that any of the investigators must have a search warrant whether they are trying to get inside of an individuals home to find evidence, or to even go through their personal computers and cell phones.

In conclusion, for computer forensics to sufficiently progress, law enforcement must keep up with the pace of the advanements in technology. Computer system searches, must have clear and consistent legal procedures that must be properly developed, so that the investigators, as well as the police, can be properly trained. Limiting the criminal abuse of technology can be done by equipping the law enforcement with state-of-the-art training, as well as the proper equipment for forensic analysis. This will enhance the law enforcements ability to be able to properly use computer forensics for each and every criminal case.

Steps For Fixing A Broken Hard Drive

broken hard driveIt’s a common disaster that your hard drive seems to b broken. So don’t panic at first sight and just follow some simple steps to confirm the points of faults and try to repair them accordingly. Here is a guideline of some do it yourself repair works but you should always seek a second opinion or ask an expert before heading on your recovering and repairing adventure.


Know the Actual Condition of the Hard Drive

  • Sometimes it may happen that your hard drive is not actually broken but the operating board behind it is faulty and causing problem. If that is the case then check for signs of scratches and burns. If you find out the problematic part then go ahead change it and your hard drive will run again. Make sure you copy and backup the files that are still intact to avoid data loss in case of a real broken hard drive.


  • Now if your drive is making loud clicking sound then quickly remove it and switch of the machine to prevent from unwanted overwriting. Thus you can salvage some data out of it either through professional help or all by yourself.


  • Check the hardware connections to find the root cause of a broken hard drive. Check if the cables bringing power are properly attached or not and if there is enough power supply. Open up the computer case and check the IDE or SATA are firmly in their places without any physical damage like bent pins.

Today’s Equivalent Of A Fire: A Data Emergency

data emergencyAll the important sectors of business and public infrastructure now depend on data organization, collection and distribution. If by any chance there is a sudden mishap that cause any of this huge database to get affected then it’s almost becomes equivalent of a fire. During this kind of data emergency people need expert help immediately to control the consequences. Here you will get a precise idea on the different types of data emergencies and the steps you can take to prevent your system’s untimely death due to technical disasters.


Types of Data Emergency

There are two kinds of data disasters that can happen.

  1. Natural Disasters: When a huge area gets affected due to any natural calamities such as flood earthquake or tsunami.
  2. Man-made Disasters: Men are frivolous by nature. So even spilling a glass of coffee may cost you your laptop. It even can be a power cut or virus software to stop you from your next important project.


Steps to take to prevent Data Emergency

With proper planning and arrangement data emergency can be avoided. If however a data emergency does happen you can contact companies that specialize in these type of services such as Drive Savers or Forensic Analyzers at To prevent this, experts recommend pre disaster planning which saves money from after emergency recovery hikes. There are three parts to this planning.

  • Preventive strategies: This part of pre disaster planning requires the user to know whether all the key metrics of (RPO) and (RTO) for various continuity business plans are meted out in the performing machineries or not. Any discrepancy can cause failure to the pre disaster planning. That includes:
  • Copying the data to tapes and sending them for secure storage in a different location. Backing up important files save a whole lot of information and money.
  • With the help of OVF [“Open Virtualization Format”] the data can easily be restored back to the database.
  • Private and hybrid cloud solutions can replicate the management data and often connect the on-site and off-site data centres.
  • Using the available cloud storage options can also help in managing off site resources and accessing data.
  • Detective Strategies: Locating the point of dispute can also help in detecting any probable data emergency. Multiple simultaneous testing can uncover the hidden bugs so that the IT professionals who use the data can work together to fight off any chances of total data disaster.
  • Corrective Measures: everyone learns from his / her mistakes. So there are some other preventive measures that you can use.
  • Installing local mirrors and using disc protection technologies from different brands.
  • Using a UPS (Uninterruptible Power Supply) can actually control sudden power surges and power cuts so that you get the required time for saving and closing everything on your own time.
  • Installing surge protectors can avoid any unwanted situation due to distorted electrical conditions.
  • Fire extinguishers or alarms can actually save you and your important belongings from blowing away.
  • Installing an Antivirus also increases the lifespan of a hard drive and save you from future data emergencies.


Data emergency is a common incident nowadays but the above mentioned tips may help you in crucial times.
