Computer Forensics Chain Of Custody

As the trend for high-specification mobile phones and computers continues at a rapid pace so too does the potential for electronic media misuse and abuse. This kind of fraudulent activity is becoming more commonly seen in legal cases, particularly with employment tribunals. Legal firms are beginning to employ the services of computer forensics experts more widely in documenting electronic evidence and providing litigation support, as this can be crucial in the outcome of cases.

Computer forensics can be used to track and provide evidence in cases of intellectual property theft, money laundering, hacking, moonlighting and the accessing of illegal or inappropriate websites. Digital forensics can also help to secure concrete evidence of illegal activity not usually associated with electronic devices including blackmail, drug dealings and abusive behaviour.

Regardless of whether digital forensics is being used in a criminal case or a civil matter (even as part of an E-discovery exercise), maintaining chain of custody is vital. This is the fully documented tracking of evidence for the period of time that the forensics team has possession of an electronic device. It ensures that each member of the team can be held accountable for any action that they take with the media.

The purpose of this chain is to log the movements of the data, how it has been stored and subsequently analysed. It is essential that this documentation presents an accurate description of any copying, transportation and storage that has occurred, to prevent any potential legal challenge.

It is worth pointing out the differences between e-discovery and computer forensics. E-discovery is the method of processing and manipulating electronically stored information to be used in legal cases. This can take the form of emails, word processed documents, images and any other type of file, which can be filtered, viewed, analysed and categorised effectively via this system. E-discovery using a forensically acquired data set is crucial in maintaining the integrity of any information present, while potentially recovering any deleted material that may be appropriate for the legal proceedings.

Computer forensics is a highly complex industry that requires the latest in product knowledge and technical expertise. Specialists will have years of experience in the on-site capturing of data from computers, servers and other forms of electronic media. This data is then analysed by their forensic analysis specialists, and used to track how a particular device has been used. All areas of the chain of custody documentation will be completed to the highest standard to ensure peace of mind for the client.

Buy Electronic Books -are They Really Cheaper Than Physical Books

Are you considering whether or not to buy electronic books? Do you want to save money on books? Are you wondering if an ereader is a good investment?

In this article you will discover why ebooks are so reasonably priced as well as why ereaders have become one of the top selling products.

It’s much cheaper to buy electronic books than it is to buy physical books. Best sellers can be bought for as little as $9.99. If you are a history buff most classics can be downloaded at no cost. Ebooks can be downloaded instantly. No need to have to wait for the book to arrive by mail nor do you have to travel to the book store to pick it up.

Ebooks cost less since they are a lot easier and cheaper to produce than printed books. With ebooks you do not need a publisher, paper, a printing press, shipping, warehousing and distribution. The only expense is the cost of paying for the software to create the ebook.

Electronic books can be read on your computer or downloaded to an electronic reader. The recent introduction of ereaders has contributed to the rising popularity of ebooks. Ereaders can hold hundreds and some even thousands of books.

This small, portable digital device makes it easy to carry a library of your favorite books with you. It is great for people who enjoy reading books more then one book at a time or individuals who like to have a book on hand to read anytime they have a few minutes of spare time.

Simply highlight a word and the dictionary will show you the definition. Wireless technology provides access to Wikipedia or Google for additional research and better comprehension.

Ereaders are able to display newspapers and magazines. Online subscriptions are cheaper then paper versions.

An digital reader makes reading convenient and fun. Most people find that once they have an electronic reader they start reading more.

Electronic Documents Is The Paperless Society A Practical Reality

It can be argued that the advent of the computer age and electronic documents is second in importance only to Johann Gutenbergs invention of the printing press in the 1450s. Once computers were firmly entrenched in the worlds offices in the early 1980s, it didnt take long for business people to start wondering whether electronic documents could become the primary means of communication. Futurists were quick to dream about the day when books would be presented strictly online as electronic documents, available to all and at much lower prices. Others saw electronic documents putting paper companies and many printers out of business.

While the reality of the electronic document revolution has panned out differently than the futurists predicted, the computer has brought extraordinary changes to communication. For example, the broad acceptance of electronic documents in everyday and business life has prompted the development of style guides and resources for citing electronic documents as references. Another sign of the impact of electronic documents is the arrival of the CIAs electronic reading room which citizens can visit online to read about items of national interest. Likewise, physicians are more and more frequently getting away from thick patient files and instead relying on electronic charts. This move to electronic documents reduces the chances of losing vital information and also dramatically cuts down the chance of prescription errors.

One challenge with electronic documents that has emerged in recent years is the discovery of the difference in pixels in an online document vs. a printed document. Companies like Microsoft are exploring ways to alter the pixel density of electronic documents to make them more eye friendly. As this science unfolds, society will be positioned to take another step toward a more paperless society.

Today, electronic documents are increasingly becoming the norm for handling personal business. More and more people each year do their banking and bill paying via electronic documents. It saves time, effort and postage. Plus, many contend that it is actually more secure than mailing a check from your mailbox and risking it being stolen.

Government itself feels strong pressure to move toward a more paperless society. The 1998 Government Paperwork Elimination Act demanded that government agencies refrain from using paper to create, modify or store official records within just four short years. This act, in and of itself, forced the government to begin accepting electronic payments and signatures. The age of electronic documents achieved a new milestone!

Today what is classified as an electronic document has expanded to include a wide range of items such as emails, photographs, letters, depositions, x-rays, claims, medical records, video clips and even voice mail. Today, organizations use Document Management Systems to organize and manage these electronic documents. With the addition of each item, the move toward a paperless society again takes a step forward.

All this being said, most experts believe that we will never become a fully paperless society. There will always be those who want to print out a document and hold it in their hands. However, as people become more comfortable with the convenience of electronic commerce, finance and communication, more and more of our lives will be handled through electronic documents and our society will, as a result, become increasingly paperless.

Example Of A Bariatric Electronic Health Records Project Scope And Objective

Electronic Health Record Systems are growing in popularity as providers move away from paper and excel spreadsheets. These systems and Bariatric Electronic Medical Record systems in particular, allow providers to do a lot more than just store patient information efficiently. A well designed and robust EHR can allow providers to better manage their practices, offer better service and better tracking of patients and allow them to compare their results over time to other providers in the EHRs network of surgeons. All of these functions contribute to improving the safety levels and the quality of health care given while generating a positive return on investment for the provider. The key to a successful implementation starts with a clear outline of the project scope and objectives and a critical evaluation of the ability of the EHR vendors ability to satisfy those requirements on time and on budget.

For example, an existing practice may define their project objective as a vision is to be recognized as a national leader in quality and patient experience. The get to that objective, the practice may need the capabilities to collect, offer and analyze the necessary compehensive patient care data related to patient outcome. In addition, the practice determined that a key part of their approach was to involve the patient more directly in the process. Therefore, the practice requires a Electronic Medical Records System that is able to provide the required information in an easy to follow and timely manner directly to existing patients. In addition, the practice emphasized that in order to continue to grow and outpace potential competition, it was imperitive that the EHR be able to track the progress of existing patients while also enabling it to reach potential customers that may have expressed interest in obtaining bariatric suregery services in a timly fashion.

The practice defined its immediate requirements as maintaining its Center of Excellence certification by generating timely and accurate data on patient outcome; increasing efficiency through reduction of data entry from multiple systems (through the development of interfaces) to one; increasing customer satisfaction; and finally, increased understanding of their current patient base, their experiences and the level and their satisfaction with follow-ups.

Since RemedyEHRs BariEHR was developed specifically for the Bariatric Practice it offers the above mentioned requirements. It was the first system to interface with the Bold National database. It manages patient progression; it generates follow-up letters, referrals, thank you letters and reminders and there is the potential to reduce entering data into a single system from up to seven systems that are used at many hospitals and clinics. In addition, the BariEHR electronic medical record system allows for the broadest ability to produce reports of any system in the industry.

Gps Antenna Selection For Embedded Applications

As more electronics are stuffed into ever decreasing sized enclosures and at a lower cost, it looks like corners are starting to be cut with respect to good engineering practice at the design stage. Below are some pointers with respect to designing in GPS antennas into handheld equipment. The experience is gained from being involved with the design of GPS equipment since 1994.

The most important item to consider is the best siting for the antenna. Even with today’s latest generation chipsets, a GPS antenna still needs a clear view of the sky especially during first acquisition when it needs to download the latest ephemeris data or on some occasions, a complete almanac.

This almanac and ephemeris data provides a virtual map to the GPS receiver allowing it to know the current and future locations and status of the satellites, relevant for that particular location. The almanac is a long-term picture of what the whole GPS network is doing whilst the ephemeris is for a short-term picture. The delay when the GPS receiver is first switched on is due to the latest ephemeris data being downloaded, which is essential for the GPS receiver. The data is valid for around 4 hours and takes approximately 20 seconds with a clear line of site to a satellite. It takes longer if using multiple satellites, for instance if the GPS receiver is moving during first acquisition.

The antenna needs to be facing the sky through a non-metallic enclosure. A metallic enclosure will prevent the RF signal being received by the antenna and cause a Faraday cage effect. Likewise, positioning the antenna near to obstructions such as laptop screen or where hands will be over the antenna should also be avoided, as the shielded will have a negative performance.

Try to avoid routing cables across other electronic equipment or backs of screens, instead try to route around the perimeter of active electronic components. Whilst it is a good idea to keep the cable relatively short, (thin RF coaxial cable used on electronic equipment has quite a high loss at 1575.42 MHz) and is susceptible to interference. However, length consideration is not essential as most GPS antennas have a 1 or 2 stage pre amplifier depending on GPS receiver used.

When designing in a GPS antenna, do not always look for the smallest possible antenna. Although this can seem attractive, particularly in hand held equipment when size is everything, the effect of a smaller GPS antenna means it is more sensitive to de-tuning.

Why? GPS works on a spot frequency of 1575.42MHz rather than a frequency range. This means that when other materials cover it – human tissue, laptop screens, it detunes the antenna away from this frequency. The smaller the antenna, the more susceptible it is to the detuning effect, which results in lack of GPS signal received.

The feedback I have received whilst helping engineers with the design in is that 25mm x 25mm patch antennas are too large but work well, whilst the 10x10mm patch antennas tick the size requirements box, however take at least 20 minutes to get into navigation. Similarly, helical antennas sound good on paper, but during field tests are poor versus a patch antenna with a comparable pre amplifier.

The sweet spots seems to be around 17x17mm. The thickness of the antenna with amplifier underneath is also now being overcome with 2mm thick ceramics now commonplace which now gives an overall thickness of around 6mm.

As old GPS users may recall, selective availability was switched off on 1st May 2000 by the US Department of Defence. This immediately gave an improved GPS navigation performance from 100m down to 10-15 metres on civilian acquired equipment. At the same time the power output from the satellites was increased.

Over 10 years on, this has resulted in a variety of GPS receiver and antenna combinations being required depending on environment the equipment will be used in.

From the antenna perspective, 1 stage Low Noise Amplifiers (LNA’s) or 2 stage LNA’s are now available on embedded GPS antennas to optimise the final design. 1 stage designs provide a gain of around 16-20dB and are reliant on either the GPS receiver having its own antenna or a very short cable run.

A 2 stage LNA provides a gain of between 25-30dB and are more popular on antennas where the GPS receiver does not have an amplifier or is unknown. Although the preconception of the higher the gain the better, this is not always true. If the gain is too high constantly, this can have an oversaturation effect on the GPS receiver, desensitising the RF front end over time and causing poor navigation. Liken it to shouting in someone’s ear. It will be very loud and the message may still not get across!
