Introduction

Increasing necessity of e-mail, Internet resources etc, offers serious security concerns. Biometrics is replacing passwords. Biometrics can be defined as recognizing and identifying a person based on physiological or behavioural characteristics.

Unlike the skin, through which near-infrared light passes, deoxygenated haemoglobin in the blood flowing through the veins absorbs near-infrared rays, causing it to be visible as black regions to the scanner. Arteries and capillaries, whose blood contains oxygenated haemoglobin, which does not absorb near-infrared light, are invisible to the sensor, hence we chosen “VEINS”.

Fujitsu research is the one main company which has come up with first basis of “PALM VEIN TECHNOLOGY".

Reflection photography:

There are two types of vein photography-

1. Reflection

Reflection is more useful technique at low ambient temperatures as blood flow decreases at cool temperatures.

2. Transmission

At cool temperatures transmission method provides low contrast images.

Advantages:

1. Very economical.

2. Highest factor of security.

3. One time registry and usage throughout life.

4. More advantageous than other biometric techniques.

Applications:

1. Managements in healthcare.

2. Operator authentication.

3. Owner authentication.

4. Attendance authentication.

Pal vein authentication:

Palm vein authentication uses the vascular patterns of an individual’s palm as personal identification data.
Compared with a finger [1] or the back of a hand, a palm has a broader and more complicated vascular pattern and thus contains a wealth of differentiating features for personal identification. The palm is an ideal part of the body for this technology; it normally does not have hair which can be an obstacle for photographing the blood vessel pattern, and it is less susceptible to…...

Hydrogen Storage

...Assignment-2 Hydrogen storage Introduction Hydrogen, the most abundant element in the universe, has great potential as an energy source. It is non-polluting, and forms water as a by-product during use. Hydrogen storage includes physical storage via compression or liquefaction, and storage in materials via reversible sorption processes or chemical reaction. Metal hydrides, Chemical hydrides and Carbon based materials are recent research topics for hydrogen storage. Metal hydrides The hydrogen storage alloys in common use occur in four different forms: AB5 (e.g., LaNi5), AB (e.g., FeTi), A2B (e.g., Mg2Ni) and AB2 (e.g., ZrV2).Research is being conducted to modify the compositions of these base alloys by alloying with various other elements. Such modifications can enhance their stability during cycles of charging and discharging, allow them to undergo cycles at ambient pressure and temperature, increase their hydrogen storage capacity, and increase their hydrogen absorption/desorption rate. Sodium aluminohydride (NaAlH4) is presently the most promising reversible complex hydride for hydrogen storage. It has a reversible storage capacity of 5.5 wt. %, whereas its total hydrogen content amounts to 7.4 wt. %. Reversible thermal dissociation occurs in two steps 3NaAlH4 ⇄ Na3AlH6 + 2Al + 3H2 (1) Na3AlH6 ⇄ 3NaH + Al + 1.5H2 ...

Cloud Storage

...Cloud Storage Flash Research Paper Cloud computing is one of the biggest buzzwords flying around the technology world lately. Our company is located in New Orleans, LA, and in 2004 when Hurricane Katrina hit we had to completely start over with our data because all backups were destroyed with the building by the water. A solid, growing and ever-cheapening option for backups for us is cloud storage. The main idea of this technology is that it keeps all backups in a completely remote location and allows it to be accessed anywhere that we can get Internet. It is a safe and fairly cheap alternative to storing backups in our own datacenter or off site down the street like we do now. According to our data needs we only need to pay the hosting site to lease the amount of storage that we use, rather than having to spend a lot on dedicated servers because they can use their multiple servers on multiple companies. The main benefit to this technology is the fact that we don’t need to do any of the tedious tasks of maintaining, purchasing, and supporting servers, they are all handled by the hosting company. Cost cutting is the main benefit there as we can focus our IT people on optimizing our company rather than paying them to maintain the backups. Also all of the servers are placed off site. One company that I found that would provide this service for us well is the company Barracuda Networks. They are situated in Campbell, CA, and completely away from our natural-disaster-prone...

Dna Storage

...DNA DATA STORAGE GOOD OR BAD? Thomas Tyrrell Will Combs With the growth of the amount of data that is now being stored, the idea behind storing that data in DNA is a fascinating one. Companies, governments and universities face an enormous challenge storing the ever-growing flood of digitized information, the videos, books, movies and songs sent over the Internet. Some researchers have looked for answers in biology. In recent years, they have found ways to encode trademarks in cells and store pieces of music in the genetic code of micro-organisms. Many movies have explored the human DNA as both an advantage and a disadvantage. Some might say that storing information in our DNA is a bad thing. But in my opinion the advantages are too great to ignore. This will open up an entirely new world for human evolution. Being able to store personal data in your own DNA will increase security levels to an unprecedented level. And with the flow of information these days the need for this security is at an all time high. The first bits of digital information were stored in DNA in 1988. However, it was impractical, both difficult and expensive. Even as recently as 2012, costs and times for reading and writing were only practical for century-scale archives. The latest development makes storing data on a 50-year timescale feasible, and archives for shorter timescales could become cost effective within a decade. A team of researchers headed by Nick Goldman and Ewan Birney at the......

Computer Storage

...COMPUTER STORAGE The device, which is used to store data, is called computer storage. We can divide computer storage into following categories. Computer Storage Permanent Secondary Temporary ROM Optical Disk Magnetic Disk Magnetic Tape RAM Cache C.D DVD H.D F.D ZIP Secondary Storage It is not possible to store large amount of data for future use in primary memory of computer because its size is small and it cannot store data on permanent basis. So it is necessary to use some extra media to store large amount of data. That kind of memory is called secondary storage, auxiliary storage, additional storage, external storage or semi-permanent storage. This memory is cheaper that primary memory due to different storage mechanism. Its speed is also slower than RAM. There are two types of secondary memory. Sequential Access Storage: Sequential Access Memory is one in which data is retrieved is in the same sequence in which it is stored. Direct/Random Access Storage: Direct Access Storage is one in which data is retrieved directly/randomly without any sequence. MAGNETIC TAPE Magnetic tape is one of the oldest & popular devices used for storing data permanently. As its name suggest, this device stores information on a magnetic tape that is made of plastic (Mylar) that is the form of magnetic spots. Size The tape ribbon itself is stored in reels of 50 to 2400 feet or small cartridge or cassette. Quality It is similar to the tape used on......

Storage Strategy

...STORAGE STRATEGY According to our forecasting, the natural gas price will increase even if it’s quite impossible to calculate the spot price on November 25th. Last year during the period September 27th – November 25th the price rose by almost 20% (from USD 3.297 to USD 3.901). Furthermore, natural gas has a seasonal trend (like other commodities) and the demand for it is usually higher during the winter (from November to March) because natural gas is used to heat residential and commercial buildings. In this case of increasing price,the best strategies are buying now : we can do it buying now at the spot price or buy now a future contract for natural gas. The only difference between the two strategies is the delivery : in the first scenario we will take delivery now whereas in the second one the delivery will take on November the 26th . As mentioned above ,a good purchasing strategy could be buy now ,September the 27th , at the spot price USD 3.50/MMBtu and taking now delivery . We have to buy CAN 5,000,000 of natural gas on the NYMEX.For doing that we are going to convert our currency in USD : on September the 27th the currency exchange is USD 1= CAN 0.9708 ,so our amount is USD 4,854,000 and we can buy 1,386,857.14 MMBtu of natural gas. ADVANTAGES Firstly, the main goal of a supplier manager is to save money instead of speculate on the commodities exchange : if we think that the price is going to increase on November 25th (and this is what emerges from our......

Cloud Storage

...meeting, or it can be as personal as photos, contact information, phone numbers, addresses, music or anniversary dates. In a sense, it is a folder; of one’s important documents. But as that information grows with a person, so too must the storage capacity of their devices. As technology continues to advance, we are now embarking on a new error, one where we are using a new storage device called, Cloud Storage. This new service is allowing people to have faster access to their personal information and even be able to have more information saved without the worries of overloading their devices with too much ‘stuff’. By definition, Cloud Storage is defined by the practice of using a network of remote servers, hosted on the Internet, to store, manage, and process data, rather than a local server or a personal computer, such as a internal or external hard drive.1 Therefore, putting your data into the ‘cloud’, such as it may, you are essentially handing it over to a provider who may have data centers in many different places, countries or even continents. In general, it really refers to saving data to an off-site storage system, which is maintained by a third party.2 Instead of storing information to your computer's hard drive or other local storage device, you would save it to a remote database....

Cloud Storage

...Week 11 Discussion 1. The days have gone when personal documents, photos and music was stored on computer’s hard drive. Cloud storage is the solution to the ever-present need of storage of all digital property. Cloud storage is an alternate to buy new hard disks and deleting old files to create space. It is convenient and cost-effective. Cloud storage stores data on a server and not local hard drive. This helps in having back up, sync and access to the data on all possible devices that have internet connection. 2. I personally feel that it is a very good way to track personal information. At the same time I also feel that the mobiles today are so high-end that they have huge storage capacity in-built. Music, photos and documents can be stored there too without the requirement of internet access and issues concerning security. However, the advantages are more in storing with cloud than on mobiles. Certain restriction with storage is there in case of mobile. The advantages and disadvantages are listed below. Advantages: * Flexibility * Low-cost * Speed * Easy management * Device Diversity * Increased storage capacity * Easy to understand * Automatic updating * Customize setting Disadvantages: * Dependency * Risk * Constant internet connection * Security * Migration......

Cloud Storage

...SWIFTSTACK TECH BRIEF Cloudy Weather for Enterprise Storage – an Enterprise Storage Veteran Looks Forward July 2014 by Dave Roberson Executive Summary This whitepaper looks at the root causes of user demands for better, cheaper storage services and IT’s options to meet those demands. In particular, it explains how the shift in value off proprietary hardware and onto open software stacks is happening in storage just as happened over the last decade with server virtualization. Enterprise storage as we have known it for the last four decades is facing significant internal and external pressures. The rapid growth of inexpensive or even free public cloud storage for consumers has created a bring-your-own storage grass-roots revolution demanding IT deliver simple self-service storage at costs far below current chargeback levels. At the same time the capacity requirements for user-generated content from sources like mobile applications is becoming a driving force in storage expansion. While public cloud options exist for enterprises they still have often unacceptable gaps in security and control despite their favorable economics compared to legacy on-premise storage. All of these factors are making it both technically and economically indefensible to just keep expanding your reliance on existing legacy NAS and SANs that suffer from years of vendor lock-in and are burdened by costly proprietary hardware. Something new is needed and the option of pushing data out to public cloud......

Hard drives are comprised of platters, have read/write heads on top and bottom for each platter. Since they are coated with magnetic film, which contain the bits, they should never be exposed to a magnet as it may result in data loss. Hard drives and gilded to protect their data, but floppy disks are not. The BIOS can be flashed to upgrade the system. The hard drives can attach to the motherboard using different interfaces, such as PATA, SATA, SCSI, USB, and FireWire; PATA (Parallel ATA) interface is most commonly used and is sometimes referred to as IDE or EIDE. The IDE (PATA) cable has 2 connector which are master and slave, the motherboard supports 2 cables which are primary and secondary. The motherboard can support 4 devices total (primary master/slave and secondary master/slave). The motherboard connector may be color coded, blue is primary and black is second. The cable connectors may also be color coded, blue goes into motherboard (regardless of primary or secondary), black goes to first device and grey is second device. The jumpers on the drive determine the master/slave designation. The hard drive should be installed as master on the primary cable, other devices should be second to improve performance.

Gas Storage

...Gas Storage With the ever growing reserves of natural gas being discovered, production of this fossil fuel is at an all-time high. Production of natural gas in the US has increased year over year for the past 11 years up to about 29 million cubic feet in 2015. With this surplus in supply, produced gas must be stored until it’s needed. There are 3 main areas where gas can be stored for longer durations once brought to surface. These 3 areas are depleted gas reservoirs, which make up about 85-90% of storage, aquifers and salt caverns. “Typically, the turn-over rate for natural gas in these facilities is a year; natural gas is generally injected during the summer (non-heating season), which usually runs from April through October, and withdrawn during the winter (heating season), usually from November to March.” (naturalgas.org). Unfortunately, this year that wasn’t the case. Due to the relative warm winter in the US, gas wasn’t needed as much as in years past and gas withdrawal from storage was at one of the lowest points in Pennsylvania history. If you pair that with record production, you can understand why the natural gas industry has been hit so hard recently. Depleted Gas Storage Fields In general these are the most common and cheapest ways to store gas. They can date back in the US all the way to 1930. These storage wells are just wells that had already been drilled and had the gas brought to the surface. This helps with the storage for a few......
