A Silent Sound Technology In Development

Sunday, June 5th, 2011

Let us assume you are in a noicy restaurent or a bus , a party etc where there is lot of noice around. This is big issue while talking on a mobile phone. But in the future this problem is eliminated with ”silent sounds”, a new technology unveiled at the CeBIT fair on Tuesday that transforms lip movements into a computer-generated voice for the listener at the other end of the phone.

The device, developed by the Karlsruhe Institute of Technology (KIT), uses electromyography, monitoring tiny muscular movements that occur when we speak and converting them into electrical pulses that can then be turned into speech, without a sound uttered.

‘Silent Sound’ technology aims to notice every movements of the lips and transform them into sounds, which could help people who lose voices to speak, and allow people to make silent calls without bothering others. Rather than making any sounds, your handset would decipher the movements your mouth makes by measuring muscle activity, then convert this into speech that the person on the other end of the call can hear. So, basically, it reads your lips.

“We currently use electrodes which are glued to the skin. In the future, such electrodes might for example by incorporated into cellphones,” said Michael Wand, from the KIT.

The technology opens up a host of applications, from helping people who have lost their voice due to illness or accident to telling a trusted friend your PIN number over the phone without anyone eavesdropping — assuming no lip-readers are around.

The technology can also turn you into an instant polyglot. Because the electrical pulses are universal, they can be immediately transformed into the language of the user’s choice.

“Native speakers can silently utter a sentence in their language, and the receivers hear the translated sentence in their language. It appears as if the native speaker produced speech in a foreign language,” said Wand.

The translation technology works for languages like English, French and Gernan, but for languages like Chinese, where different tones can hold many different meanings, poses a problem, he added.

Noisy people in your office? Not any more. “We are also working on technology to be used in an office environment,” the KIT scientist told AFP.

The engineers have got the device working to 99 percent efficiency, so the mechanical voice at the other end of the phone gets one word in 100 wrong, explained Wand.

This technology is expected to come soon in markets about 5 years from now. And if the development goes well, it may turn up soon. I cant imagine , what kind of revolution would this technology bring about. Its seems really difficult to accomplish such an act.

The things that this technology may solve are:- clear sounds even when there is noise, the people who cant actually speak could then speak, because they would just have to make lip movements, the places where you should not make a noise there too you can talk without actually making noise. If there are anymore advances in this technology , then it is expected that intelligence agencies could use it to listen to what people speak, even when there are no actual microphones added to devices.

You can read stuff like that on Firehorizon and also similar stuff on Fxmultitech

Review Of Dell Streak 7 Android Tablet

Thursday, May 5th, 2011

It wouldn’t be wrong to think of the Dell Streak 5 as a compromise between a high end smartphone, and a boughed down tablet. It contained aspects from both Dell Streak with the technical expertise of Dell. The Dell Streak 7 removes all doubts by proudly placing itself in the ever growing stable of tablets.

The 10mm-thick block has a 7″ screen is meant for today’s age of streaming video, web meetings and full screen browser displays, for once actually working comfortably under the sun. Add to that the fact that its a comfy fit in your hand unlike its 10″ tablet brethren in the market. Reinforced with the famous Gorilla Glass, you can safely expose the surface of the Dell Streak as much as you want without any damage done.

The Android 2.2-based tablet, also America’s First 4G Android, with integrated social networking features. Add to that the expanding Android apps market, and you can virtually get all possible virtual work done with this gizmo. The sleek body nicely integrates with the 3 buttons on its surface, and a strong grip body to go along with it. The facility for social networking is useful for easy uploading of media to facebook and flickr almost immediately. The Dell Streak is packed with a “1GHz dual-core Tegra T20 processor”, which allows a smooth multi processing environment from the Android smartphone. The phone comes with the latest communication add-ons with 4G” HSPA+ connectivity, bluetooth and wi-fi under the hood. To fill in you have 16GB of internal memory, and in case you need more storage space, given the rapid rise of HD, there is the swappable MicroSD slot, to fill in more. To complement the physical design, the Dell Streak is packed with an intuitive design, that is a level up from the original Android base. The drag and drop functionality exists for all apps, the Google Voice Support is relevant to most apps, search criterias, and the Streak comes closely synched with A-GPS and e compass mapping facilities, to get you enroute to your destination real fast.

The smartphone has dual camera operability with a 1.3 megapixel front facing camera and a back 5-MP cam with dual flash for the capturing the best look. The camera is commendable in its qulaity with the macro shots and zoom pics showing up really good compared to other smart phones in its range. There are 6 scene options (Automatic, Night, Portrait, Lan Dell Streakcape, Sport and Snow) and each Dell Streak a specific ambiance to the picture. It also supports four White Balance presets. The downside to an otherwise complete tablet is the wire entanglement where you need to lug your USB cord for uploading and the AC adapter for charing the gizmo up. The visual display is sleek and shiny until you place your sight on the Samsung Galaxy Tab and realize the display for Streak could do a bit more enhancement for the screen resolution, as it is of a lower scale.

Check Out The Online World Using Fast Broadband

Wednesday, October 20th, 2010

The adjustments that the web has been subject to ever since it primarily entered the bulk market in the midst of the 1990s when it first commenced showing up in our households, it was a totally unique animal to what we now acknowledge.

When we initially got the online world in homes, most of internet sites were not considerably more developed than essentially the most amateurish attempts we view now. Many had certain images, a touch of text, a few hyperlinks and maybe a GIF that did not seem quite a bit just like anything at all.

A main cause for this was that just highly well qualified web designers had the experience to do something significantly more. Also, even when you possessed the capability to develop a top quality website you would have been hard pushed to locate a connection solid enough to work with it.

In case you even now have dial-up, but yet have employed broadband, you will have acknowledged a big variation in between both. Dial-up would probably nonetheless perform good for lower-powered websites, but in case you make an effort to see video or look over an intricate web page, it really is over.

Not each and every location basically has broadband access at the existing time, whilst its access increases by the day. You really should seek advice from your current vendor and others to find out if they may produce it for you – for a tiny price rise, it produces a large variation.

At one time that you’re on broadband, you don’t possess the interminable delay to download anything at all but the most basic file, or maybe curse the person who despatched you a photo in an email since it decreases the entire computer system down.

Obviously, it would be a lie to state that mobilt bredbånd is infallible – just like something technical, it is just not. However the difficulties are much less numerous and damaging compared to dial-up.

In fact, bredbånd priser access will ensure that you get significantly more potential in anything you do via the internet, from social networks to video clip sharing, that entails much more information and facts than what dial-up can cope with.

Nokia Morph – The Nano Technology Mobile

Saturday, June 19th, 2010

Nano Technology Mobile Launched alongside The Museum of Modern Art “Design and The Elastic Mind” exhibition, the Morph concept device is a bridge between highly advanced technologies and their potential benefits to end-users. This device concept showcases some revolutionary leaps being explored by Nokia Research Center (NRC) in collaboration with the Cambridge Nanoscience Centre (United Kingdom) – nanoscale technologies that will potentially create a world of radically different devices that open up an entirely new spectrum of possibilities.

Morph concept technologies might create fantastic opportunities for mobile devices:

* Newly-enabled flexible and transparent materials blend more seamlessly with the way we live
* Devices become self-cleaning and self-preserving
* Transparent electronics offering an entirely new aesthetic dimension
* Built-in solar absorption might charge a device, whilst batteries become smaller, longer lasting and faster to charge
* Integrated sensors might allow us to learn more about the environment around us, empowering us to make better choices

%KEYWORDS1% Nano Technology Mobile

In addition to the advances above, the integrated electronics shown in the Morph concept could cost less and include more functionality in a much smaller space, even as interfaces are simplified and usability is enhanced. All of these new capabilities will unleash new applications and services that will allow us to communicate and interact in unprecedented ways.

Flexible & Changing Design

Nanotechnology enables materials and components that are flexible, stretchable, transparent and remarkably strong. Fibril proteins are woven into a three dimensional mesh that reinforces thin elastic structures. Using the same principle behind spider silk, this elasticity enables the device to literally change shapes and configure itself to adapt to the task at hand.

A folded design would fit easily in a pocket and could lend itself ergonomically to being used as a traditional handset. An unfolded larger design could display more detailed information, and incorporate input devices such as keyboards and touch pads.

Even integrated electronics, from interconnects to sensors, could share these flexible properties. Further, utilization of biodegradable materials might make production and recycling of devices easier and ecologically friendly.

Self-Cleaning

Nanotechnology also can be leveraged to create self-cleaning surfaces on mobile devices, ultimately reducing corrosion, wear and improving longevity. Nanostructured surfaces, such as “Nanoflowers” naturally repel water, dirt, and even fingerprints utilizing effects also seen in natural systems.

Advanced Power Sources

Nanotechnology holds out the possibility that the surface of a device will become a natural source of energy via a covering of “Nanograss” structures that harvest solar power. At the same time new high energy density storage materials allow batteries to become smaller and thinner, while also quicker to recharge and able to endure more charging cycles.

Sensing The Environment

Nanosensors would empower users to examine the environment around them in completely new ways, from analyzing air pollution, to gaining insight into bio-chemical traces and processes. New capabilities might be as complex as helping us monitor evolving conditions in the quality of our surroundings, or as simple as knowing if the fruit we are about to enjoy should be washed before we eat it. Our ability to tune into our environment in these ways can help us make key decisions that guide our daily actions and ultimately can enhance our health.

Why Cell Forensic Are Valuable For Law Enforcement

Saturday, February 6th, 2010

If you are still investigating pay phones, then you are existing in antiquated history. As we enter the next ten years of the twentieth century, a lot of people are using mobile phones – including the suspects that we analyze.

As cell telephones have evolved, it does not make a great deal of sense any longer to just call the devices “telephones.”. In fact, the title “mini computer” would be a more suitable title for these mighty little communication devices. Telephones like the blackberry and iphone are notably influential sources of investigative evidence.

Widespread belief among most – in particular smaller – police departments is that investigating cell forensics is more scientific than they have the time or the people to handle. But this is simply not the case. Take a look overseas: the UK, and other nearby Eurpean nations, are far more advanced that the United States when it comes to extracting forensic information out of mobile phones. This progression was not that taxing; it really only took a willingness to recognize that cell phone forensics are valuable for investigations. We will discuss importance of cell forensics in this article. In another article on Cell Forensics Download, we discuss cell forensics acquisition hardware.

Though it may seem to be a trivial question if you have any experience with telephone forensics|mobile device forensics[/spin], no double several pd cops might want a definition for telephone forensics|mobile device forensics[/spin]. Here is a good definition:

The removal and investigation of information from mobile telephones seized by investigators.
To aquire these cell phones from targets, they are usually captured during an arrest or when a hunt warrent is exercised. The way to legally get hold of cell phones for investigations is not the point of this editorial – we have to suppose that you are somewhat familiar with the fundamentals of criminal justice. Seek advice from your defense attorney to make certain that you obtain the telephones corectly. Remember that the method from start to finish needs to be documented for court.

Cell forensic data includes:

- Emails ( in the case of smartphones)
- Address books
- Pictures (occationallly including geo-information!)
-Text messages
-Call Detail Records (aka numbers called and numbers calling)

The importance of mobile forensics forensics|mobile device forensics[/spin] is rather clear.

They can with no trouble generate the next lead of your analysis, but they also provide valuable perspective for your suspects. Who is called most often by your suspect? Who is getting his emails? What individuals are a element of his inner group of co-conspirators?

Simply receiving information off of a handset, however, is not enough. You need a way to analyze the information. It is not uncommon for forensic law enforcment to rave about the number of files they are able to pull off a particilar handset. However, the only point of pulling information from a telephone is to generate leads and the resulting evidence with ANALYSIS.

In another article later in this series on Cell Forensics Software, we will hit on some cell forensics investigation system that turns the data from the aquisition devices (like the Cellebrite, Secureview, or XRY) and actually transforms it into actionable intelligence automatically.

Processing BlackBerry Backup (.bbb) Files

Tuesday, October 20th, 2009

If you didn’t already know, there is now a Mac version of the Blackberry Desktop Manager available. When used, the program allows a user to create a full backup of their device both automatically, or on-demand – encrypted, or not. I have only tried this out a couple of times, so here is what I can tell you so far…

The files have the extension “.bbb” – not the traditional .ipd file we are used to and appears to use the following naming convention:

  • “BlackBerry”<MODEL_NAME> (<DEVICE_PIN>) (<YYYYMM-DD>) -<TYPE_OF_BACKUP>.bbb
  • If another .bbb file is created on the same date, a numeric identifier and additional “-” is be added to the naming convention between the (<YYYYMM-DD>) and the <TYPE_OF_BACKUP> field
  • Example file names: “BlackBerry Storm (XXXXXXXX) (2009-10-02) – Full.zip” and “BlackBerry Storm (XXXXXXXX) (2009-10-02) – 2 – Full.zip”

The .bbb file appears to be a compound file which contains the following items in the root once explored:

  • BlackBerry_Backup.xml – contains an apparent list of artifacts with the quantity of each reported
  • Directory: Applications – may be empty
  • Directory: Databases – Contains a “Databases.ipd” file
  • Directory: Internal_Media_Card – may be empty, but if not, the file inside will be named “archive_xxxxxxxxx.zip” and will contain data backed up from the media card

Although the latest version (7.15) of ABC Amber Blackberry Converter does NOT yet support the .bbb file, you can still process these files in one of two ways:

  • Bring the .bbb file into FTK or EnCase and navigate down to the Databases directory to
export the .ipd file
  • Simply change the .bbb extension to .zip and export the .ipd file
  • Add the .ipd to ABC for analysis and reporting

Regardless of encryption, the .bbb file can be opened and the .xml file and directory structure reported above can still be viewed:

  • The .xml still reports the same data as the non-encrypted backup
  • If the .ipd is encrypted, a value will be reported within the following tags in the .xml file: “<salt>XXXXXX</salt>”
  • If the .ipd is encrypted, the first 48 bytes of the file will read: “Inter@ctive Pager Backup/ Restore File Encryption”
  • If the .ipd is not encrypted, the value will be absent and the tag will read: “<salt />”
  • If the .ipd is not encrypted, the first 48 bytes of the file will read: “Inter@ctive PagerBackup/Restore File..a…Atta” – notice the word “Encryption” is missing

If you have additional information related to the processing of .bbb files, feel free to email me with details!

The Debate Over “Mobile Forensics” – Really?!

Friday, October 2nd, 2009

This seems to be an ongoing debate that has a simple explanation (in my opinion)…

1. Start with the basic definition of forensics and move forward from there.

SOURCE: http://www.merriam-webster.com/dictionary/forensic
- Function: adjective
- Etymology: Latin forensis public, forensic, from forum forum
- Date: 1659
1: belonging to, used in, or suitable to courts of judicature or to public discussion and debate
2: argumentative, rhetorical
3: relating to or dealing with the application of scientific knowledge to legal problems

2. Let’s move on to define “computer forensics”
SOURCE: US CERT: http://www.us-cert.gov/reading_room/forensics.pdf

“We define computer forensics as the discipline that combines elements of law and and computer science to collect and analyze data from computer systems, networks, wireless communications, and storage devices in a way that is admissible as evidence in a court of law.“

Remember that there are methodologies used in computer forensics which may be destructive, or not preserve the “original” because of the process used. There are also processes in traditional crime laboratories (DNA, biology, etc.) that also use destructive methodologies, leaving no way for a second examination to take place – even for the defense!

Why do we tend to think that if a tool is marketed as “forensic” – that in fact it is? Don’t we do verification and validation? What happens when we do a logical acquisition of a server? Is it not fact that we are leaving data behind and could be construed as “non-forensic” because it is not a true “bit-by-bit” image?

We all know that cellular telephones are devices that contain data. The only reason there is ANY debate is because companies have developed “forensic” products for these devices. The fact comes down to the examiner’s methodologies used to preserve, analyze, and present the evidence in a legal proceeding.

What we must do as examiners has been roughly outlined in a draft document that I had the honor to be invited to participate in authoring with Sam Brothers, Rick Ayers, and other forensic examiners with the Scientific Working Group on Digital Evidence this past January. The document is titled “Best Practices for Mobile Phone Examinations v1.0” and is available for download, review and your comments at http://swgde.org/documents.html.

There is no debate that cellular telephone data changes all the time. But, we as examiners must recognize that what we are most interested in on cellular telephones is user generated data. We want to see the call logs, text messages, photos, videos, dates and times of activities, etc. This data is written to the phone operating system and is usually retrievable through non-traditional methodologies.

There are also times that we will NOT be able to retrieve the information using “forensic” products, “non-forensic” products (to include flash boxes, bitpim), etc. Do we not oftentimes have “no choice” but to take pictures of the screens we manually navigate to document what the user did? What about if the screen is broken, and there is no way to create a “fraternal clone” 1 as we did back in 2004 when a phone was destroyed and thrown into a canal for a few days? The evidence is there – it is just a matter of documenting HOW you got what you got! At the “tip of the iceberg” is the chip-off technique that is destructive, yet has been used to pull data from phones when all else fails.

The SWGDE document referenced above should help anyone with questions on what is “acceptable” in this field – for now. SWGDE meets again next week to hopefully finalize this document. You still have a chance to submit your comments at their site. Unfortunately, I will not be at this meeting due to a prior teaching engagement. However, my senior examiner will be there, as well as Sam, Rick and others who read these postings.

Finally, another project I gave input on was the often debated certification at www.mfce.us. That’s my 2 cents on the subject…
